Reply Obj. 2: Although things are immutably in God, yet in themselves they are subject to change. To this it is that the blotting out of the book of life refers.

Reply Obj. 3: The way in which one is said to be blotted out of the book of life is that in which one is said to be written therein anew; either in the opinion of men, or because he begins again to have relation towards eternal life through grace; which also is included in the knowledge of God, although not anew. _____________________

QUESTION 25

THE POWER OF GOD (In Six Articles)

After considering the divine foreknowledge and will, and other things pertaining thereto, it remains for us to consider the power of God. About this are six points of inquiry:

(1) Whether there is power in God?

(2) Whether His power is infinite?

(3) Whether He is almighty?

(4) Whether He could make the past not to have been?

(5) Whether He could do what He does not, or not do what He does?

(6) Whether what He makes He could make better? _____________________

FIRST ARTICLE [I, Q. 25, Art. 1]

Whether There Is Power in God?

Objection 1: It seems that power is not in God. For as primary matter is to power, so God, who is the first agent, is to act. But primary matter, considered in itself, is devoid of all act. Therefore, the first agent--namely, God--is devoid of power.

Obj. 2: Further, according to the Philosopher (Metaph. vi, 19), better than every power is its act. For form is better than matter; and action than active power, since it is its end. But nothing is better than what is in God; because whatsoever is in God, is God, as was shown above (Q. 3, A. 3). Therefore, there is no power in God.

Obj. 3: Further, Power is the principle of operation. But the divine power is God's essence, since there is nothing accidental in God: and of the essence of God there is no principle. Therefore there is no power in God.

Obj. 4: Further, it was shown above (Q. 14, A. 8; Q. 19, A. 4) that God's knowledge and will are the cause of things. But the cause and principle of a thing are identical. We ought not, therefore, to assign power to God; but only knowledge and will.

On the contrary, It is said: "Thou art mighty, O Lord, and Thy truth is round about Thee" (Ps. 88:9).

I answer that, Power is twofold--namely, passive, which exists not at all in God; and active, which we must assign to Him in the highest degree. For it is manifest that everything, according as it is in act and is perfect, is the active principle of something: whereas everything is passive according as it is deficient and imperfect. Now it was shown above (Q. 3, A. 2; Q. 4, AA. 1, 2), that God is pure act, simply and in all ways perfect, nor in Him does any imperfection find place. Whence it most fittingly belongs to Him to be an active principle, and in no way whatsoever to be passive. On the other hand, the notion of active principle is consistent with active power. For active power is the principle of acting upon something else; whereas passive power is the principle of being acted upon by something else, as the Philosopher says (Metaph. v, 17). It remains, therefore, that in God there is active power in the highest degree.

Reply Obj. 1: Active power is not contrary to act, but is founded upon it, for everything acts according as it is actual: but passive power is contrary to act; for a thing is passive according as it is potential. Whence this potentiality is not in God, but only active power.

Reply Obj. 2: Whenever act is distinct from power, act must be nobler than power. But God's action is not distinct from His power, for both are His divine essence; neither is His existence distinct from His essence. Hence it does not follow that there should be anything in God nobler than His power.

Reply Obj. 3: In creatures, power is the principle not only of action, but likewise of effect. Thus in God the idea of power is retained, inasmuch as it is the principle of an effect; not, however, as it is a principle of action, for this is the divine essence itself; except, perchance, after our manner of understanding, inasmuch as the divine essence, which pre-contains in itself all perfection that exists in created things, can be understood either under the notion of action, or under that of power; as also it is understood under the notion of suppositum possessing nature, and under that of nature. Accordingly the notion of power is retained in God in so far as it is the principle of an effect.

Reply Obj. 4: Power is predicated of God not as something really distinct from His knowledge and will, but as differing from them logically; inasmuch as power implies a notion of a principle putting into execution what the will commands, and what knowledge directs, which three things in God are identified. Or we may say, that the knowledge or will of God, according as it is the effective principle, has the notion of power contained in it. Hence the consideration of the knowledge and will of God precedes the consideration of His power, as the cause precedes the operation and effect. _____________________

SECOND ARTICLE [I, Q. 25, Art. 2]

Whether the Power of God Is Infinite?

Objection 1: It seems that the power of God is not infinite. For everything that is infinite is imperfect according to the Philosopher (Phys. iii, 6). But the power of God is far from imperfect. Therefore it is not infinite.

Obj. 2: Further, every power is made known by its effect; otherwise it would be ineffectual. If, then, the power of God were infinite, it could produce an infinite effect, but this is impossible.

Obj. 3: Further, the Philosopher proves (Phys. viii, 79) that if the power of any corporeal thing were infinite, it would cause instantaneous movement. God, however, does not cause instantaneous movement, but moves the spiritual creature in time, and the corporeal creature in place and time, as Augustine says (Gen. ad lit. 20, 22, 23). Therefore, His power is not infinite.

On the contrary, Hilary says (De Trin. viii), that "God's power is immeasurable. He is the living mighty one." Now everything that is immeasurable is infinite. Therefore the power of God is infinite.

I answer that, As stated above (A. 1), active power exists in God according to the measure in which He is actual. Now His existence is infinite, inasmuch as it is not limited by anything that receives it, as is clear from what has been said, when we discussed the infinity of the divine essence (Q. 7, A. 1). Wherefore, it is necessary that the active power in God should be infinite. For in every agent is it found that the more perfectly an agent has the form by which it acts the greater its power to act. For instance, the hotter a thing is, the greater the power has it to give heat; and it would have infinite power to give heat, were its own heat infinite. Whence, since the divine essence, through which God acts, is infinite, as was shown above (Q. 7, A. 1) it follows that His power likewise is infinite.

Reply Obj. 1: The Philosopher is here speaking of an infinity in regard to matter not limited by any form; and such infinity belongs to quantity. But the divine essence is otherwise, as was shown above (Q. 7, A. 1); and consequently so also His power. It does not follow, therefore, that it is imperfect.

Reply Obj. 2: The power of a univocal agent is wholly manifested in its effect. The generative power of man, for example, is not able to do more than beget man. But the power of a non-univocal agent does not wholly manifest itself in the production of its effect: as, for example, the power of the sun does not wholly manifest itself in the production of an animal generated from putrefaction. Now it is clear that God is not a univocal agent. For nothing agrees with Him either in species or in genus, as was shown above (Q. 3, A. 5; Q. 4, A. 3). Whence it follows that His effect is always less than His power. It is not necessary, therefore, that the infinite power of God should be manifested so as to produce an infinite effect. Yet even if it were to produce no effect, the power of God would not be ineffectual; because a thing is ineffectual which is ordained towards an end to which it does not attain. But the power of God is not ordered toward its effect as towards an end; rather, it is the end of the effect produced by it.

Reply Obj. 3: The Philosopher (Phys. viii, 79) proves that if a body had infinite power, it would cause a non-temporal movement. And he shows that the power of the mover of heaven is infinite, because it can move in an infinite time. It remains, therefore, according to his reckoning, that the infinite power of a body, if such existed, would move without time; not, however, the power of an incorporeal mover. The reason of this is that one body moving another is a univocal agent; wherefore it follows that the whole power of the agent is made known in its motion. Since then the greater the power of a moving body, the more quickly does it move; the necessary conclusion is that if its power were infinite, it would move beyond comparison faster, and this is to move without time. An incorporeal mover, however, is not a univocal agent; whence it is not necessary that the whole of its power should be manifested in motion, so as to move without time; and especially since it moves in accordance with the disposition of its will. _____________________

THIRD ARTICLE [I, Q. 25, Art. 3]

Whether God Is Omnipotent?

Objection 1: It seems that God is not omnipotent. For movement and passiveness belong to everything. But this is impossible with God, for He is immovable, as was said above (Q. 2, A. 3). Therefore He is not omnipotent.

Obj. 2: Further, sin is an act of some kind. But God cannot sin, nor "deny Himself" as it is said in 2 Tim. 2:13. Therefore He is not omnipotent.

Obj. 3: Further, it is said of God that He manifests His omnipotence "especially by sparing and having mercy" [*Collect, 10th Sunday after Pentecost]. Therefore the greatest act possible to the divine power is to spare and have mercy. There are things much greater, however, than sparing and having mercy; for example, to create another world, and the like. Therefore God is not omnipotent.

Obj. 4: Further, upon the text, "God hath made foolish the wisdom of this world" (1 Cor. 1:20), a gloss says: "God hath made the wisdom of this world foolish [*Vulg.: 'Hath not God', etc.] by showing those things to be possible which it judges to be impossible." Whence it would seem that nothing is to be judged possible or impossible in reference to inferior causes, as the wisdom of this world judges them; but in reference to the divine power. If God, then, were omnipotent, all things would be possible; nothing, therefore impossible. But if we take away the impossible, then we destroy also the necessary; for what necessarily exists is impossible not to exist. Therefore there would be nothing at all that is necessary in things if God were omnipotent. But this is an impossibility. Therefore God is not omnipotent.

On the contrary, It is said: "No word shall be impossible with God" (Luke 1:37).

I answer that, All confess that God is omnipotent; but it seems difficult to explain in what His omnipotence precisely consists: for there may be doubt as to the precise meaning of the word 'all' when we say that God can do all things. If, however, we consider the matter aright, since power is said in reference to possible things, this phrase, "God can do all things," is rightly understood to mean that God can do all things that are possible; and for this reason He is said to be omnipotent. Now according to the Philosopher (Metaph. v, 17), a thing is said to be possible in two ways. First in relation to some power, thus whatever is subject to human power is said to be possible to man. Secondly absolutely, on account of the relation in which the very terms stand to each other. Now God cannot be said to be omnipotent through being able to do all things that are possible to created nature; for the divine power extends farther than that. If, however, we were to say that God is omnipotent because He can do all things that are possible to His power, there would be a vicious circle in explaining the nature of His power. For this would be saying nothing else but that God is omnipotent, because He can do all that He is able to do.

It remains therefore, that God is called omnipotent because He can do all things that are possible absolutely; which is the second way of saying a thing is possible. For a thing is said to be possible or impossible absolutely, according to the relation in which the very terms stand to one another, possible if the predicate is not incompatible with the subject, as that Socrates sits; and absolutely impossible when the predicate is altogether incompatible with the subject, as, for instance, that a man is a donkey.

It must, however, be remembered that since every agent produces an effect like itself, to each active power there corresponds a thing possible as its proper object according to the nature of that act on which its active power is founded; for instance, the power of giving warmth is related as to its proper object to the being capable of being warmed. The divine existence, however, upon which the nature of power in God is founded, is infinite, and is not limited to any genus of being; but possesses within itself the perfection of all being. Whence, whatsoever has or can have the nature of being, is numbered among the absolutely possible things, in respect of which God is called omnipotent. Now nothing is opposed to the idea of being except non-being. Therefore, that which implies being and non-being at the same time is repugnant to the idea of an absolutely possible thing, within the scope of the divine omnipotence. For such cannot come under the divine omnipotence, not because of any defect in the power of God, but because it has not the nature of a feasible or possible thing. Therefore, everything that does not imply a contradiction in terms, is numbered amongst those possible things, in respect of which God is called omnipotent: whereas whatever implies contradiction does not come within the scope of divine omnipotence, because it cannot have the aspect of possibility. Hence it is better to say that such things cannot be done, than that God cannot do them. Nor is this contrary to the word of the angel, saying: "No word shall be impossible with God." For whatever implies a contradiction cannot be a word, because no intellect can possibly conceive such a thing.

Reply Obj. 1: God is said to be omnipotent in respect to His active power, not to passive power, as was shown above (A. 1). Whence the fact that He is immovable or impassible is not repugnant to His omnipotence.

Reply Obj. 2: To sin is to fall short of a perfect action; hence to be able to sin is to be able to fall short in action, which is repugnant to omnipotence. Therefore it is that God cannot sin, because of His omnipotence. Nevertheless, the Philosopher says (Topic. iv, 3) that God can deliberately do what is evil. But this must be understood either on a condition, the antecedent of which is impossible--as, for instance, if we were to say that God can do evil things if He will. For there is no reason why a conditional proposition should not be true, though both the antecedent and consequent are impossible: as if one were to say: "If man is a donkey, he has four feet." Or he may be understood to mean that God can do some things which now seem to be evil: which, however, if He did them, would then be good. Or he is, perhaps, speaking after the common manner of the heathen, who thought that men became gods, like Jupiter or Mercury.

Reply Obj. 3: God's omnipotence is particularly shown in sparing and having mercy, because in this is it made manifest that God has supreme power, that He freely forgives sins. For it is not for one who is bound by laws of a superior to forgive sins of his own free will. Or, because by sparing and having mercy upon men, He leads them on to the participation of an infinite good; which is the ultimate effect of the divine power. Or because, as was said above (Q. 21, A. 4), the effect of the divine mercy is the foundation of all the divine works. For nothing is due to anyone, except on account of something already given him gratuitously by God. In this way the divine omnipotence is particularly made manifest, because to it pertains the first foundation of all good things.

Reply Obj. 4: The absolute possible is not so called in reference either to higher causes, or to inferior causes, but in reference to itself. But the possible in reference to some power is named possible in reference to its proximate cause. Hence those things which it belongs to God alone to do immediately--as, for example, to create, to justify, and the like--are said to be possible in reference to a higher cause. Those things, however, which are of such kind as to be done by inferior causes are said to be possible in reference to those inferior causes. For it is according to the condition of the proximate cause that the effect has contingency or necessity, as was shown above (Q. 14, A. 1, ad 2). Thus is it that the wisdom of the world is deemed foolish, because what is impossible to nature, it judges to be impossible to God. So it is clear that the omnipotence of God does not take away from things their impossibility and necessity. _____________________

FOURTH ARTICLE [I, Q. 25, Art. 4]

Whether God Can Make the Past Not to Have Been?

Objection 1: It seems that God can make the past not to have been. For what is impossible in itself is much more impossible than that which is only impossible accidentally. But God can do what is impossible in itself, as to give sight to the blind, or to raise the dead. Therefore, and much more can He do what is only impossible accidentally. Now for the past not to have been is impossible accidentally: thus for Socrates not to be running is accidentally impossible, from the fact that his running is a thing of the past. Therefore God can make the past not to have been.

Obj. 2: Further, what God could do, He can do now, since His power is not lessened. But God could have effected, before Socrates ran, that he should not run. Therefore, when he has run, God could effect that he did not run.

Obj. 3: Further, charity is a more excellent virtue than virginity. But God can supply charity that is lost; therefore also lost virginity. Therefore He can so effect that what was corrupt should not have been corrupt.

On the contrary, Jerome says (Ep. 22 ad Eustoch.): "Although God can do all things, He cannot make a thing that is corrupt not to have been corrupted." Therefore, for the same reason, He cannot effect that anything else which is past should not have been.

I answer that, As was said above (Q. 7, A. 2), there does not fall under the scope of God's omnipotence anything that implies a contradiction. Now that the past should not have been implies a contradiction. For as it implies a contradiction to say that Socrates is sitting, and is not sitting, so does it to say that he sat, and did not sit. But to say that he did sit is to say that it happened in the past. To say that he did not sit, is to say that it did not happen. Whence, that the past should not have been, does not come under the scope of divine power. This is what Augustine means when he says (Contra Faust. xxix, 5): "Whosoever says, If God is almighty, let Him make what is done as if it were not done, does not see that this is to say: If God is almighty let Him effect that what is true, by the very fact that it is true, be false": and the Philosopher says (Ethic. vi, 2): "Of this one thing alone is God deprived--namely, to make undone the things that have been done."

Reply Obj. 1: Although it is impossible accidentally for the past not to have been, if one considers the past thing itself, as, for instance, the running of Socrates; nevertheless, if the past thing is considered as past, that it should not have been is impossible, not only in itself, but absolutely since it implies a contradiction. Thus, it is more impossible than the raising of the dead; in which there is nothing contradictory, because this is reckoned impossible in reference to some power, that is to say, some natural power; for such impossible things do come beneath the scope of divine power.

Reply Obj. 2: As God, in accordance with the perfection of the divine power, can do all things, and yet some things are not subject to His power, because they fall short of being possible; so, also, if we regard the immutability of the divine power, whatever God could do, He can do now. Some things, however, at one time were in the nature of possibility, whilst they were yet to be done, which now fall short of the nature of possibility, when they have been done. So is God said not to be able to do them, because they themselves cannot be done.

Reply Obj. 3: God can remove all corruption of the mind and body from a woman who has fallen; but the fact that she had been corrupt cannot be removed from her; as also is it impossible that the fact of having sinned or having lost charity thereby can be removed from the sinner. _____________________

FIFTH ARTICLE [I, Q. 25, Art. 5]

Whether God Can Do What He Does Not?

Objection 1: It seems that God cannot do other than what He does. For God cannot do what He has not foreknown and pre-ordained that He would do. But He neither foreknew nor pre-ordained that He would do anything except what He does. Therefore He cannot do except what He does.

Obj. 2: Further, God can only do what ought to be done and what is right to be done. But God is not bound to do what He does not; nor is it right that He should do what He does not. Therefore He cannot do except what He does.

Obj. 3: Further, God cannot do anything that is not good and befitting creation. But it is not good for creatures nor befitting them to be otherwise than as they are. Therefore God cannot do except what He does.

On the contrary, It is said: "Thinkest thou that I cannot ask My Father, and He will give Me presently more than twelve legions of angels?" (Matt. 26:53). But He neither asked for them, nor did His Father show them to refute the Jews. Therefore God can do what He does not.

I answer that, In this matter certain persons erred in two ways. Some laid it down that God acts from natural necessity in such way that as from the action of nature nothing else can happen beyond what actually takes place--as, for instance, from the seed of man, a man must come, and from that of an olive, an olive; so from the divine operation there could not result other things, nor another order of things, than that which now is. But we showed above (Q. 19, A. 3) that God does not act from natural necessity, but that His will is the cause of all things; nor is that will naturally and from any necessity determined to those things. Whence in no way at all is the present course of events produced by God from any necessity, so that other things could not happen. Others, however, said that the divine power is restricted to this present course of events through the order of the divine wisdom and justice without which God does nothing. But since the power of God, which is His essence, is nothing else but His wisdom, it can indeed be fittingly said that there is nothing in the divine power which is not in the order of the divine wisdom; for the divine wisdom includes the whole potency of the divine power. Yet the order placed in creation by divine wisdom, in which order the notion of His justice consists, as said above (Q. 21, A. 2), is not so adequate to the divine wisdom that the divine wisdom should be restricted to this present order of things. Now it is clear that the whole idea of order which a wise man puts into things made by him is taken from their end. So, when the end is proportionate to the things made for that end, the wisdom of the maker is restricted to some definite order. But the divine goodness is an end exceeding beyond all proportion things created. Whence the divine wisdom is not so restricted to any particular order that no other course of events could happen. Wherefore we must simply say that God can do other things than those He has done.

Reply Obj. 1: In ourselves, in whom power and essence are distinct from will and intellect, and again intellect from wisdom, and will from justice, there can be something in the power which is not in the just will nor in the wise intellect. But in God, power and essence, will and intellect, wisdom and justice, are one and the same. Whence, there can be nothing in the divine power which cannot also be in His just will or in His wise intellect. Nevertheless, because His will cannot be determined from necessity to this or that order of things, except upon supposition, as was said above (Q. 19, A. 3), neither are the wisdom and justice of God restricted to this present order, as was shown above; so nothing prevents there being something in the divine power which He does not will, and which is not included in the order which He has place in things. Again, because power is considered as executing, the will as commanding, and the intellect and wisdom as directing; what is attributed to His power considered in itself, God is said to be able to do in accordance with His absolute power. Of such a kind is everything which has the nature of being, as was said above (A. 3). What is, however, attributed to the divine power, according as it carries into execution the command of a just will, God is said to be able to do by His ordinary power. In this manner, we must say that God can do other things by His absolute power than those He has foreknown and pre-ordained He would do. But it could not happen that He should do anything which He had not foreknown, and had not pre-ordained that He would do, because His actual doing is subject to His foreknowledge and pre-ordination, though His power, which is His nature, is not so. For God does things because He wills so to do; yet the power to do them does not come from His will, but from His nature.

Reply Obj. 2: God is bound to nobody but Himself. Hence, when it is said that God can only do what He ought, nothing else is meant by this than that God can do nothing but what is befitting to Himself, and just. But these words "befitting" and "just" may be understood in two ways: one, in direct connection with the verb "is"; and thus they would be restricted to the present order of things; and would concern His power. Then what is said in the objection is false; for the sense is that God can do nothing except what is now fitting and just. If, however, they be joined directly with the verb "can" (which has the effect of extending the meaning), and then secondly with "is," the present will be signified, but in a confused and general way. The sentence would then be true in this sense: "God cannot do anything except that which, if He did it, would be suitable and just."

Reply Obj. 3: Although this order of things be restricted to what now exists, the divine power and wisdom are not thus restricted. Whence, although no other order would be suitable and good to the things which now are, yet God can do other things and impose upon them another order. _____________________

SIXTH ARTICLE [I, Q. 25, Art. 6]

Whether God Can Do Better Than What He Does?

Objection 1: It seems that God cannot do better than He does. For whatever God does, He does in a most powerful and wise way. But a thing is so much the better done as it is more powerfully and wisely done. Therefore God cannot do anything better than He does.

Obj. 2: Further, Augustine thus argues (Contra Maximin. iii, 8): "If God could, but would not, beget a Son His equal, He would have been envious." For the same reason, if God could have made better things than He has done, but was not willing so to do, He would have been envious. But envy is far removed from God. Therefore God makes everything of the best. He cannot therefore make anything better than He does.

Obj. 3: Further, what is very good and the best of all cannot be bettered; because nothing is better than the best. But as Augustine says (Enchiridion 10), "each thing that God has made is good, and, taken all together they are very good; because in them all consists the wondrous beauty of the universe." Therefore the good in the universe could not be made better by God.

Obj. 4: Further, Christ as man is full of grace and truth, and has the Spirit without measure; and so He cannot be better. Again created happiness is described as the highest good, and thus cannot be better. And the Blessed Virgin Mary is raised above all the choirs of angels, and so cannot be better than she is. God cannot therefore make all things better than He has made them.

On the contrary, It is said (Eph. 3:20): "God is able to do all things more abundantly than we desire or understand."

I answer that, The goodness of anything is twofold; one, which is of the essence of it--thus, for instance, to be rational pertains to the essence of man. As regards this good, God cannot make a thing better than it is itself; although He can make another thing better than it; even as He cannot make the number four greater than it is; because if it were greater it would no longer be four, but another number. For the addition of a substantial difference in definitions is after the manner of the addition of unity of numbers (Metaph. viii, 10). Another kind of goodness is that which is over and above the essence; thus, the good of a man is to be virtuous or wise. As regards this kind of goodness, God can make better the things He has made. Absolutely speaking, however, God can make something else better than each thing made by Him.

Reply Obj. 1: When it is said that God can make a thing better than He makes it, if "better" is taken substantively, this proposition is true. For He can always make something else better than each individual thing: and He can make the same thing in one way better than it is, and in another way not; as was explained above. If, however, "better" is taken as an adverb, implying the manner of the making; thus God cannot make anything better than He makes it, because He cannot make it from greater wisdom and goodness. But if it implies the manner of the thing done, He can make something better; because He can give to things made by Him a better manner of existence as regards the accidents, although not as regards the substance.

Reply Obj. 2: It is of the nature of a son that he should be equal to his father, when he comes to maturity. But it is not of the nature of anything created, that it should be better than it was made by God. Hence the comparison fails.

Reply Obj. 3: The universe, the present creation being supposed, cannot be better, on account of the most beautiful order given to things by God; in which the good of the universe consists. For if any one thing were bettered, the proportion of order would be destroyed; as if one string were stretched more than it ought to be, the melody of the harp would be destroyed. Yet God could make other things, or add something to the present creation; and then there would be another and a better universe.

Reply Obj. 4: The humanity of Christ, from the fact that it is united to the Godhead; and created happiness from the fact that it is the fruition of God; and the Blessed Virgin from the fact that she is the mother of God; have all a certain infinite dignity from the infinite good, which is God. And on this account there cannot be anything better than these; just as there cannot be anything better than God. _____________________

QUESTION 26

OF THE DIVINE BEATITUDE (In Four Articles)

After considering all that pertains to the unity of the divine essence, we come to treat of the divine beatitude. Concerning this, there are four points of inquiry:

(1) Whether beatitude belongs to God?

(2) In regard to what is God called blessed; does this regard His act of intellect?

(3) Whether He is essentially the beatitude of each of the blessed?

(4) Whether all other beatitude is included in the divine beatitude? _____________________

FIRST ARTICLE [I, Q. 26, Art. 1]

Whether Beatitude Belongs to God?

Objection 1: It seems that beatitude does not belong to God. For beatitude according to Boethius (De Consol. iv) "is a state made perfect by the aggregation of all good things." But the aggregation of goods has no place in God; nor has composition. Therefore beatitude does not belong to God.

Obj. 2: Further, beatitude or happiness is the reward of virtue, according to the Philosopher (Ethic. i, 9). But reward does not apply to God; as neither does merit. Therefore neither does beatitude.

On the contrary, The Apostle says: "Which in His times He shall show, who is the Blessed and only Almighty, the King of Kings and Lord of Lords." (1 Tim. 6:15).

I answer that, Beatitude belongs to God in a very special manner. For nothing else is understood to be meant by the term beatitude than the perfect good of an intellectual nature; which is capable of knowing that it has a sufficiency of the good which it possesses, to which it is competent that good or ill may befall, and which can control its own actions. All of these things belong in a most excellent manner to God, namely, to be perfect, and to possess intelligence. Whence beatitude belongs to God in the highest degree.

Reply Obj. 1: Aggregation of good is in God, after the manner not of composition, but of simplicity; for those things which in creatures is manifold, pre-exist in God, as was said above (Q. 4, A. 2; Q. 13, A. 4), in simplicity and unity.

Reply Obj. 2: It belongs as an accident to beatitude or happiness to be the reward of virtue, so far as anyone attains to beatitude; even as to be the term of generation belongs accidentally to a being, so far as it passes from potentiality to act. As, then, God has being, though not begotten; so He has beatitude, although not acquired by merit. _____________________

SECOND ARTICLE [I, Q. 26, Art. 2]

Whether God Is Called Blessed in Respect of His Intellect?

Objection 1: It seems that God is not called blessed in respect to His intellect. For beatitude is the highest good. But good is said to be in God in regard to His essence, because good has reference to being which is according to essence, according to Boethius (De Hebdom.). Therefore beatitude also is said to be in God in regard to His essence, and not to His intellect.

Obj. 2: Further, Beatitude implies the notion of end. Now the end is the object of the will, as also is the good. Therefore beatitude is said to be in God with reference to His will, and not with reference to His intellect.

On the contrary, Gregory says (Moral. xxxii, 7): "He is in glory, Who whilst He rejoices in Himself, needs not further praise." To be in glory, however, is the same as to be blessed. Therefore, since we enjoy God in respect to our intellect, because "vision is the whole of the reward," as Augustine says (De Civ. Dei xxii), it would seem that beatitude is said to be in God in respect of His intellect. it would seem that beatitude is said to be in God in respect of His intellect.

I answer that, Beatitude, as stated above (A. 1), is the perfect good of an intellectual nature. Thus it is that, as everything desires the perfection of its nature, intellectual nature desires naturally to be happy. Now that which is most perfect in any intellectual nature is the intellectual operation, by which in some sense it grasps everything. Whence the beatitude of every intellectual nature consists in understanding. Now in God, to be and to understand are one and the same thing; differing only in the manner of our understanding them. Beatitude must therefore be assigned to God in respect of His intellect; as also to the blessed, who are called blessed [beati] by reason of the assimilation to His beatitude.

Reply Obj. 1: This argument proves that beatitude belongs to God; not that beatitude pertains essentially to Him under the aspect of His essence; but rather under the aspect of His intellect.

Reply Obj. 2: Since beatitude is a good, it is the object of the will; now the object is understood as prior to the act of a power. Whence in our manner of understanding, divine beatitude precedes the act of the will at rest in it. This cannot be other than the act of the intellect; and thus beatitude is to be found in an act of the intellect. _____________________

THIRD ARTICLE [I, Q. 26, Art. 3]

Whether God Is the Beatitude of Each of the Blessed?

Objection 1: It seems that God is the beatitude of each of the blessed. For God is the supreme good, as was said above (Q. 6, AA. 2, 4). But it is quite impossible that there should be many supreme goods, as also is clear from what has been said above (Q. 11, A. 3). Therefore, since it is of the essence of beatitude that it should be the supreme good, it seems that beatitude is nothing else but God Himself.

Obj. 2: Further, beatitude is the last end of the rational nature. But to be the last end of the rational nature belongs only to God. Therefore the beatitude of every blessed is God alone.

On the contrary, The beatitude of one is greater than that of another, according to 1 Cor. 15:41: "Star differeth from star in glory." But nothing is greater than God. Therefore beatitude is something different from God.

I answer that, The beatitude of an intellectual nature consists in an act of the intellect. In this we may consider two things, namely, the object of the act, which is the thing understood; and the act itself which is to understand. If, then, beatitude be considered on the side of the object, God is the only beatitude; for everyone is blessed from this sole fact, that he understands God, in accordance with the saying of Augustine (Confess. v, 4): "Blessed is he who knoweth Thee, though he know nought else." But as regards the act of understanding, beatitude is a created thing in beatified creatures; but in God, even in this way, it is an uncreated thing.

Reply Obj. 1: Beatitude, as regards its object, is the supreme good absolutely, but as regards its act, in beatified creatures it is their supreme good, not absolutely, but in that kind of goods which a creature can participate.

Reply Obj. 2: End is twofold, namely, objective and subjective,as the Philosopher says (Greater Ethics i, 3), namely, the "thing itself" and "its use." Thus to a miser the end is money, and its acquisition. Accordingly God is indeed the last end of a rational creature, as the thing itself; but created beatitude is the end, as the use, or rather fruition, of the thing. _____________________

FOURTH ARTICLE [I, Q. 26, Art. 4]

Whether All Other Beatitude Is Included in the Beatitude of God?

Objection 1: It seems that the divine beatitude does not embrace all other beatitudes. For there are some false beatitudes. But nothing false can be in God. Therefore the divine beatitude does not embrace all other beatitudes.

Obj. 2: Further, a certain beatitude, according to some, consists in things corporeal; as in pleasure, riches, and such like. Now none of these have to do with God, since He is incorporeal. Therefore His beatitude does not embrace all other beatitudes.

On the contrary, Beatitude is a certain perfection. But the divine perfection embraces all other perfection, as was shown above (Q. 4, A. 2). Therefore the divine beatitude embraces all other beatitudes.

I answer that, Whatever is desirable in whatsoever beatitude, whether true or false, pre-exists wholly and in a more eminent degree in the divine beatitude. As to contemplative happiness, God possesses a continual and most certain contemplation of Himself and of all things else; and as to that which is active, He has the governance of the whole universe. As to earthly happiness, which consists in delight, riches, power, dignity, and fame, according to Boethius (De Consol. iii, 10), He possesses joy in Himself and all things else for His delight; instead of riches He has that complete self-sufficiency, which is promised by riches; in place of power, He has omnipotence; for dignities, the government of all things; and in place of fame, He possesses the admiration of all creatures.

Reply Obj. 1: A particular kind of beatitude is false according as it falls short of the idea of true beatitude; and thus it is not in God. But whatever semblance it has, howsoever slight, of beatitude, the whole of it pre-exists in the divine beatitude.

Reply Obj. 2: The good that exists in things corporeal in a corporeal manner, is also in God, but in a spiritual manner.

We have now spoken enough concerning what pertains to the unity of the divine essence. _____________________

TREATISE ON THE MOST HOLY TRINITY (QQ. 27-43) _____________________

QUESTION 27

THE PROCESSION OF THE DIVINE PERSONS (In Five Articles)

Having considered what belongs to the unity of the divine essence, it remains to treat of what belongs to the Trinity of the persons in God. And because the divine Persons are distinguished from each other according to the relations of origin, the order of the doctrine leads us to consider firstly, the question of origin or procession; secondly, the relations of origin; thirdly, the persons.

Concerning procession there are five points of inquiry:

(1) Whether there is procession in God?

(2) Whether any procession in God can be called generation?

(3) Whether there can be any other procession in God besides generation?

(4) Whether that other procession can be called generation?

(5) Whether there are more than two processions in God? _____________________

FIRST ARTICLE [I, Q. 27, Art. 1]

Whether There Is Procession in God?

Objection 1: It would seem that there cannot be any procession in God. For procession signifies outward movement. But in God there is nothing mobile, nor anything extraneous. Therefore neither is there procession in God.

Obj. 2: Further, everything which proceeds differs from that whence it proceeds. But in God there is no diversity; but supreme simplicity. Therefore in God there is no procession.

Obj. 3: Further, to proceed from another seems to be against the nature of the first principle. But God is the first principle, as shown above (Q. 2, A. 3). Therefore in God there is no procession.

On the contrary, Our Lord says, "From God I proceeded" (John 8:42).

I answer that, Divine Scripture uses, in relation to God, names which signify procession. This procession has been differently understood. Some have understood it in the sense of an effect, proceeding from its cause; so Arius took it, saying that the Son proceeds from the Father as His primary creature, and that the Holy Ghost proceeds from the Father and the Son as the creature of both. In this sense neither the Son nor the Holy Ghost would be true God: and this is contrary to what is said of the Son, "That . . . we may be in His true Son. This is true God" (1 John 5:20). Of the Holy Ghost it is also said, "Know you not that your members are the temple of the Holy Ghost?" (1 Cor. 6:19). Now, to have a temple is God's prerogative. Others take this procession to mean the cause proceeding to the effect, as moving it, or impressing its own likeness on it; in which sense it was understood by Sabellius, who said that God the Father is called Son in assuming flesh from the Virgin, and that the Father also is called Holy Ghost in sanctifying the rational creature, and moving it to life. The words of the Lord contradict such a meaning, when He speaks of Himself, "The Son cannot of Himself do anything" (John 5:19); while many other passages show the same, whereby we know that the Father is not the Son. Careful examination shows that both of these opinions take procession as meaning an outward act; hence neither of them affirms procession as existing in God Himself; whereas, since procession always supposes action, and as there is an outward procession corresponding to the act tending to external matter, so there must be an inward procession corresponding to the act remaining within the agent. This applies most conspicuously to the intellect, the action of which remains in the intelligent agent. For whenever we understand, by the very fact of understanding there proceeds something within us, which is a conception of the object understood, a conception issuing from our intellectual power and proceeding from our knowledge of that object. This conception is signified by the spoken word; and it is called the word of the heart signified by the word of the voice.

As God is above all things, we should understand what is said of God, not according to the mode of the lowest creatures, namely bodies, but from the similitude of the highest creatures, the intellectual substances; while even the similitudes derived from these fall short in the representation of divine objects. Procession, therefore, is not to be understood from what it is in bodies, either according to local movement or by way of a cause proceeding forth to its exterior effect, as, for instance, like heat from the agent to the thing made hot. Rather it is to be understood by way of an intelligible emanation, for example, of the intelligible word which proceeds from the speaker, yet remains in him. In that sense the Catholic Faith understands procession as existing in God.

Reply Obj. 1: This objection comes from the idea of procession in the sense of local motion, or of an action tending to external matter, or to an exterior effect; which kind of procession does not exist in God, as we have explained.

Reply Obj. 2: Whatever proceeds by way of outward procession is necessarily distinct from the source whence it proceeds, whereas, whatever proceeds within by an intelligible procession is not necessarily distinct; indeed, the more perfectly it proceeds, the more closely it is one with the source whence it proceeds. For it is clear that the more a thing is understood, the more closely is the intellectual conception joined and united to the intelligent agent; since the intellect by the very act of understanding is made one with the object understood. Thus, as the divine intelligence is the very supreme perfection of God (Q. 14, A. 2), the divine Word is of necessity perfectly one with the source whence He proceeds, without any kind of diversity.

Reply Obj. 3: To proceed from a principle, so as to be something outside and distinct from that principle, is irreconcilable with the idea of a first principle; whereas an intimate and uniform procession by way of an intelligible act is included in the idea of a first principle. For when we call the builder the principle of the house, in the idea of such a principle is included that of his art; and it would be included in the idea of the first principle were the builder the first principle of the house. God, Who is the first principle of all things, may be compared to things created as the architect is to things designed. _____________________

SECOND ARTICLE [I, Q. 27, Art. 2]

Whether Any Procession in God Can Be Called Generation?

Objection 1: It would seem that no procession in God can be called generation. For generation is change from non-existence to existence, and is opposed to corruption; while matter is the subject of both. Nothing of all this belongs to God. Therefore generation cannot exist in God.

Obj. 2: Further, procession exists in God, according to an intelligible mode, as above explained (A. 1). But such a process is not called generation in us; therefore neither is it to be so called in God.

Obj. 3: Further, anything that is generated derives existence from its generator. Therefore such existence is a derived existence. But no derived existence can be a self-subsistence. Therefore, since the divine existence is self-subsisting (Q. 3, A. 4), it follows that no generated existence can be the divine existence. Therefore there is no generation in God.

On the contrary, It is said (Ps. 2:7): "This day have I begotten Thee."

I answer that, The procession of the Word in God is called generation. In proof whereof we must observe that generation has a twofold meaning: one common to everything subject to generation and corruption; in which sense generation is nothing but change from non-existence to existence. In another sense it is proper and belongs to living things; in which sense it signifies the origin of a living being from a conjoined living principle; and this is properly called birth. Not everything of that kind, however, is called begotten; but, strictly speaking, only what proceeds by way of similitude. Hence a hair has not the aspect of generation and sonship, but only that has which proceeds by way of a similitude. Nor will any likeness suffice; for a worm which is generated from animals has not the aspect of generation and sonship, although it has a generic similitude; for this kind of generation requires that there should be a procession by way of similitude in the same specific nature; as a man proceeds from a man, and a horse from a horse. So in living things, which proceed from potential to actual life, such as men and animals, generation includes both these kinds of generation. But if there is a being whose life does not proceed from potentiality to act, procession (if found in such a being) excludes entirely the first kind of generation; whereas it may have that kind of generation which belongs to living things. So in this manner the procession of the Word in God is generation; for He proceeds by way of intelligible action, which is a vital operation:--from a conjoined principle (as above described):--by way of similitude, inasmuch as the concept of the intellect is a likeness of the object conceived:--and exists in the same nature, because in God the act of understanding and His existence are the same, as shown above (Q. 14, A. 4). Hence the procession of the Word in God is called generation; and the Word Himself proceeding is called the Son.

Reply Obj. 1: This objection is based on the idea of generation in the first sense, importing the issuing forth from potentiality to act; in which sense it is not found in God.

Reply Obj. 2: The act of human understanding in ourselves is not the substance itself of the intellect; hence the word which proceeds within us by intelligible operation is not of the same nature as the source whence it proceeds; so the idea of generation cannot be properly and fully applied to it. But the divine act of intelligence is the very substance itself of the one who understands (Q. 14, A. 4). The Word proceeding therefore proceeds as subsisting in the same nature; and so is properly called begotten, and Son. Hence Scripture employs terms which denote generation of living things in order to signify the procession of the divine Wisdom, namely, conception and birth; as is declared in the person of the divine Wisdom, "The depths were not as yet, and I was already conceived; before the hills, I was brought forth." (Prov. 8:24). In our way of understanding we use the word "conception" in order to signify that in the word of our intellect is found the likeness of the thing understood, although there be no identity of nature.

Reply Obj. 3: Not everything derived from another has existence in another subject; otherwise we could not say that the whole substance of created being comes from God, since there is no subject that could receive the whole substance. So, then, what is generated in God receives its existence from the generator, not as though that existence were received into matter or into a subject (which would conflict with the divine self-subsistence); but when we speak of His existence as received, we mean that He Who proceeds receives divine existence from another; not, however, as if He were other from the divine nature. For in the perfection itself of the divine existence are contained both the Word intelligibly proceeding and the principle of the Word, with whatever belongs to His perfection (Q. 4, A. 2). _____________________

THIRD ARTICLE [I, Q. 27, Art. 3]

Whether Any Other Procession Exists in God Besides That of the Word?

Objection 1: It would seem that no other procession exists in God besides the generation of the Word. Because, for whatever reason we admit another procession, we should be led to admit yet another, and so on to infinitude; which cannot be. Therefore we must stop at the first, and hold that there exists only one procession in God.

Obj. 2: Further, every nature possesses but one mode of self-communication; because operations derive unity and diversity from their terms. But procession in God is only by way of communication of the divine nature. Therefore, as there is only one divine nature (Q. 11, A. 4), it follows that only one procession exists in God.

Obj. 3: Further, if any other procession but the intelligible procession of the Word existed in God, it could only be the procession of love, which is by the operation of the will. But such a procession is identified with the intelligible procession of the intellect, inasmuch as the will in God is the same as His intellect (Q. 19, A. 1). Therefore in God there is no other procession but the procession of the Word.

On the contrary, The Holy Ghost proceeds from the Father (John 15:26); and He is distinct from the Son, according to the words, "I will ask My Father, and He will give you another Paraclete" (John 14:16). Therefore in God another procession exists besides the procession of the Word.

I answer that, There are two processions in God; the procession of the Word, and another.

In evidence whereof we must observe that procession exists in God, only according to an action which does not tend to anything external, but remains in the agent itself. Such an action in an intellectual nature is that of the intellect, and of the will. The procession of the Word is by way of an intelligible operation. The operation of the will within ourselves involves also another procession, that of love, whereby the object loved is in the lover; as, by the conception of the word, the object spoken of or understood is in the intelligent agent. Hence, besides the procession of the Word in God, there exists in Him another procession called the procession of love.

Reply Obj. 1: There is no need to go on to infinitude in the divine processions; for the procession which is accomplished within the agent in an intellectual nature terminates in the procession of the will.

Reply Obj. 2: All that exists in God, is God (Q. 3, AA. 3, 4); whereas the same does not apply to others. Therefore the divine nature is communicated by every procession which is not outward, and this does not apply to other natures.

Reply Obj. 3: Though will and intellect are not diverse in God, nevertheless the nature of will and intellect requires the processions belonging to each of them to exist in a certain order. For the procession of love occurs in due order as regards the procession of the Word; since nothing can be loved by the will unless it is conceived in the intellect. So as there exists a certain order of the Word to the principle whence He proceeds, although in God the substance of the intellect and its concept are the same; so, although in God the will and the intellect are the same, still, inasmuch as love requires by its very nature that it proceed only from the concept of the intellect, there is a distinction of order between the procession of love and the procession of the Word in God. _____________________

FOURTH ARTICLE [I, Q. 27, Art. 4]

Whether the Procession of Love in God Is Generation?

Objection 1: It would seem that the procession of love in God is generation. For what proceeds by way of likeness of nature among living things is said to be generated and born. But what proceeds in God by way of love proceeds in the likeness of nature; otherwise it would be extraneous to the divine nature, and would be an external procession. Therefore what proceeds in God by way of love, proceeds as generated and born.

Obj. 2: Further, as similitude is of the nature of the word, so does it belong to love. Hence it is said, that "every beast loves its like" (Ecclus. 13:19). Therefore if the Word is begotten and born by way of likeness, it seems becoming that love should proceed by way of generation.

Obj. 3: Further, what is not in any species is not in the genus. So if there is a procession of love in God, there ought to be some special name besides this common name of procession. But no other name is applicable but generation. Therefore the procession of love in God is generation.

On the contrary, Were this true, it would follow that the Holy Ghost Who proceeds as love, would proceed as begotten; which is against the statement of Athanasius: "The Holy Ghost is from the Father and the Son, not made, nor begotten, but proceeding."

I answer that, The procession of love in God ought not to be called generation. In evidence whereof we must consider that the intellect and the will differ in this respect, that the intellect is made actual by the object understood residing according to its own likeness in the intellect; whereas the will is made actual, not by any similitude of the object willed within it, but by its having a certain inclination to the thing willed. Thus the procession of the intellect is by way of similitude, and is called generation, because every generator begets its own like; whereas the procession of the will is not by way of similitude, but rather by way of impulse and movement towards an object.

So what proceeds in God by way of love, does not proceed as begotten, or as son, but proceeds rather as spirit; which name expresses a certain vital movement and impulse, accordingly as anyone is described as moved or impelled by love to perform an action.

Reply Obj. 1: All that exists in God is one with the divine nature. Hence the proper notion of this or that procession, by which one procession is distinguished from another, cannot be on the part of this unity: but the proper notion of this or that procession must be taken from the order of one procession to another; which order is derived from the nature of the will and intellect. Hence, each procession in God takes its name from the proper notion of will and intellect; the name being imposed to signify what its nature really is; and so it is that the Person proceeding as love receives the divine nature, but is not said to be born.

Reply Obj. 2: Likeness belongs in a different way to the word and to love. It belongs to the word as being the likeness of the object understood, as the thing generated is the likeness of the generator; but it belongs to love, not as though love itself were a likeness, but because likeness is the principle of loving. Thus it does not follow that love is begotten, but that the one begotten is the principle of love.

Reply Obj. 3: We can name God only from creatures (Q. 13, A. 1). As in creatures generation is the only principle of communication of nature, procession in God has no proper or special name, except that of generation. Hence the procession which is not generation has remained without a special name; but it can be called spiration, as it is the procession of the Spirit. _____________________

FIFTH ARTICLE [I, Q. 27, Art. 5]

Whether There Are More Than Two Processions in God?

Objection 1: It would seem that there are more than two processions in God. As knowledge and will are attributed to God, so is power. Therefore, if two processions exist in God, of intellect and will, it seems that there must also be a third procession of power.

Obj. 2: Further, goodness seems to be the greatest principle of procession, since goodness is diffusive of itself. Therefore there must be a procession of goodness in God.

Obj. 3: Further, in God there is greater power of fecundity than in us. But in us there is not only one procession of the word, but there are many: for in us from one word proceeds another; and also from one love proceeds another. Therefore in God there are more than two processions.

On the contrary, In God there are not more than two who proceed--the Son and the Holy Ghost. Therefore there are in Him but two processions.

I answer that, The divine processions can be derived only from the actions which remain within the agent. In a nature which is intellectual, and in the divine nature these actions are two, the acts of intelligence and of will. The act of sensation, which also appears to be an operation within the agent, takes place outside the intellectual nature, nor can it be reckoned as wholly removed from the sphere of external actions; for the act of sensation is perfected by the action of the sensible object upon sense. It follows that no other procession is possible in God but the procession of the Word, and of Love.

Reply Obj. 1: Power is the principle whereby one thing acts on another. Hence it is that external action points to power. Thus the divine power does not imply the procession of a divine person; but is indicated by the procession therefrom of creatures.

Reply Obj. 2: As Boethius says (De Hebdom.), goodness belongs to the essence and not to the operation, unless considered as the object of the will.

Thus, as the divine processions must be denominated from certain actions; no other processions can be understood in God according to goodness and the like attributes except those of the Word and of love, according as God understands and loves His own essence, truth and goodness.

Reply Obj. 3: As above explained (Q. 14, A. 5; Q. 19, A. 5), God understands all things by one simple act; and by one act also He wills all things. Hence there cannot exist in Him a procession of Word from Word, nor of Love from Love: for there is in Him only one perfect Word, and one perfect Love; thereby being manifested His perfect fecundity. _____________________

QUESTION 28

THE DIVINE RELATIONS (In Four Articles)

The divine relations are next to be considered, in four points of inquiry:

(1) Whether there are real relations in God?

(2) Whether those relations are the divine essence itself, or are extrinsic to it?

(3) Whether in God there can be several relations distinct from each other?

(4) The number of these relations. _____________________

FIRST ARTICLE [I, Q. 28, Art. 1]

Whether There Are Real Relations in God?

Objection 1: It would seem that there are no real relations in God. For Boethius says (De Trin. iv), "All possible predicaments used as regards the Godhead refer to the substance; for nothing can be predicated relatively." But whatever really exists in God can be predicated of Him. Therefore no real relation exists in God.

Obj. 2: Further, Boethius says (De Trin. iv) that, "Relation in the Trinity of the Father to the Son, and of both to the Holy Ghost, is the relation of the same to the same." But a relation of this kind is only a logical one; for every real relation requires and implies in reality two terms. Therefore the divine relations are not real relations, but are formed only by the mind.

Obj. 3: Further, the relation of paternity is the relation of a principle. But to say that God is the principle of creatures does not import any real relation, but only a logical one. Therefore paternity in God is not a real relation; while the same applies for the same reason to the other relations in God.

Obj. 4: Further, the divine generation proceeds by way of an intelligible word. But the relations following upon the operation of the intellect are logical relations. Therefore paternity and filiation in God, consequent upon generation, are only logical relations.

On the contrary, The Father is denominated only from paternity; and the Son only from filiation. Therefore, if no real paternity or filiation existed in God, it would follow that God is not really Father or Son, but only in our manner of understanding; and this is the Sabellian heresy.

I answer that, relations exist in God really; in proof whereof we may consider that in relations alone is found something which is only in the apprehension and not in reality. This is not found in any other genus; forasmuch as other genera, as quantity and quality, in their strict and proper meaning, signify something inherent in a subject. But relation in its own proper meaning signifies only what refers to another. Such regard to another exists sometimes in the nature of things, as in those things which by their own very nature are ordered to each other, and have a mutual inclination; and such relations are necessarily real relations; as in a heavy body is found an inclination and order to the centre; and hence there exists in the heavy body a certain respect in regard to the centre and the same applies to other things. Sometimes, however, this regard to another, signified by relation, is to be found only in the apprehension of reason comparing one thing to another, and this is a logical relation only; as, for instance, when reason compares man to animal as the species to the genus. But when something proceeds from a principle of the same nature, then both the one proceeding and the source of procession, agree in the same order; and then they have real relations to each other. Therefore as the divine processions are in the identity of the same nature, as above explained (Q. 27, AA. 2, 4), these relations, according to the divine processions, are necessarily real relations.

Reply Obj. 1: Relationship is not predicated of God according to its proper and formal meaning, that is to say, in so far as its proper meaning denotes comparison to that in which relation is inherent, but only as denoting regard to another. Nevertheless Boethius did not wish to exclude relation in God; but he wished to show that it was not to be predicated of Him as regards the mode of inherence in Himself in the strict meaning of relation; but rather by way of relation to another.

Reply Obj. 2: The relation signified by the term "the same" is a logical relation only, if in regard to absolutely the same thing; because such a relation can exist only in a certain order observed by reason as regards the order of anything to itself, according to some two aspects thereof. The case is otherwise, however, when things are called the same, not numerically, but generically or specifically. Thus Boethius likens the divine relations to a relation of identity, not in every respect, but only as regards the fact that the substance is not diversified by these relations, as neither is it by relation of identity.

Reply Obj. 3: As the creature proceeds from God in diversity of nature, God is outside the order of the whole creation, nor does any relation to the creature arise from His nature; for He does not produce the creature by necessity of His nature, but by His intellect and will, as is above explained (Q. 14, AA. 3, 4; Q. 19, A. 8). Therefore there is no real relation in God to the creature; whereas in creatures there is a real relation to God; because creatures are contained under the divine order, and their very nature entails dependence on God. On the other hand, the divine processions are in one and the same nature. Hence no parallel exists.

Reply Obj. 4: Relations which result from the mental operation alone in the objects understood are logical relations only, inasmuch as reason observes them as existing between two objects perceived by the mind. Those relations, however, which follow the operation of the intellect, and which exist between the word intellectually proceeding and the source whence it proceeds, are not logical relations only, but are real relations; inasmuch as the intellect and the reason are real things, and are really related to that which proceeds from them intelligibly; as a corporeal thing is related to that which proceeds from it corporeally. Thus paternity and filiation are real relations in God. _____________________

SECOND ARTICLE [I, Q. 28, Art. 2]

Whether Relation in God Is the Same As His Essence?

Objection 1: It would seem that the divine relation is not the same as the divine essence. For Augustine says (De Trin. v) that "not all that is said of God is said of His substance, for we say some things relatively, as Father in respect of the Son: but such things do not refer to the substance." Therefore the relation is not the divine essence.

Obj. 2: Further, Augustine says (De Trin. vii) that, "every relative expression is something besides the relation expressed, as master is a man, and slave is a man." Therefore, if relations exist in God, there must be something else besides relation in God. This can only be His essence. Therefore essence differs from relation.

Obj. 3: Further, the essence of relation is the being referred to another, as the Philosopher says (Praedic. v). So if relation is the divine essence, it follows that the divine essence is essentially itself a relation to something else; whereas this is repugnant to the perfection of the divine essence, which is supremely absolute and self-subsisting (Q. 3, A. 4). Therefore relation is not the divine essence.

On the contrary, Everything which is not the divine essence is a creature. But relation really belongs to God; and if it is not the divine essence, it is a creature; and it cannot claim the adoration of latria; contrary to what is sung in the Preface: "Let us adore the distinction of the Persons, and the equality of their Majesty."

I answer that, It is reported that Gilbert de la Porree erred on this point, but revoked his error later at the council of Rheims. For he said that the divine relations are assistant, or externally affixed.

To perceive the error here expressed, we must consider that in each of the nine genera of accidents there are two points for remark. One is the nature belonging to each one of them considered as an accident; which commonly applies to each of them as inherent in a subject, for the essence of an accident is to inhere. The other point of remark is the proper nature of each one of these genera. In the genera, apart from that of relation, as in quantity and quality, even the true idea of the genus itself is derived from a respect to the subject; for quantity is called the measure of substance, and quality is the disposition of substance. But the true idea of relation is not taken from its respect to that in which it is, but from its respect to something outside. So if we consider even in creatures, relations formally as such, in that aspect they are said to be "assistant," and not intrinsically affixed, for, in this way, they signify a respect which affects a thing related and tends from that thing to something else; whereas, if relation is considered as an accident, it inheres in a subject, and has an accidental existence in it. Gilbert de la Porree considered relation in the former mode only.

Now whatever has an accidental existence in creatures, when considered as transferred to God, has a substantial existence; for there is no accident in God; since all in Him is His essence. So, in so far as relation has an accidental existence in creatures, relation really existing in God has the existence of the divine essence in no way distinct therefrom. But in so far as relation implies respect to something else, no respect to the essence is signified, but rather to its opposite term.

Thus it is manifest that relation really existing in God is really the same as His essence and only differs in its mode of intelligibility; as in relation is meant that regard to its opposite which is not expressed in the name of essence. Thus it is clear that in God relation and essence do not differ from each other, but are one and the same.

Reply Obj. 1: These words of Augustine do not imply that paternity or any other relation which is in God is not in its very being the same as the divine essence; but that it is not predicated under the mode of substance, as existing in Him to Whom it is applied; but as a relation. So there are said to be two predicaments only in God, since other predicaments import habitude to that of which they are spoken, both in their generic and in their specific nature; but nothing that exists in God can have any relation to that wherein it exists or of whom it is spoken, except the relation of identity; and this by reason of God's supreme simplicity.

Reply Obj. 2: As the relation which exists in creatures involves not only a regard to another, but also something absolute, so the same applies to God, yet not in the same way. What is contained in the creature above and beyond what is contained in the meaning of relation, is something else besides that relation; whereas in God there is no distinction, but both are one and the same; and this is not perfectly expressed by the word "relation," as if it were comprehended in the ordinary meaning of that term. For it was above explained (Q. 13, A. 2), in treating of the divine names, that more is contained in the perfection of the divine essence than can be signified by any name. Hence it does not follow that there exists in God anything besides relation in reality; but only in the various names imposed by us.

Reply Obj. 3: If the divine perfection contained only what is signified by relative names, it would follow that it is imperfect, being thus related to something else; as in the same way, if nothing more were contained in it than what is signified by the word "wisdom," it would not in that case be a subsistence. But as the perfection of the divine essence is greater than can be included in any name, it does not follow, if a relative term or any other name applied to God signify something imperfect, that the divine essence is in any way imperfect; for the divine essence comprehends within itself the perfection of every genus (Q. 4, A. 2). _____________________

THIRD ARTICLE [I, Q. 28, Art. 3]

Whether the Relations in God Are Really Distinguished from Each Other?

Objection 1: It would seem that the divine relations are not really distinguished from each other. For things which are identified with the same, are identified with each other. But every relation in God is really the same as the divine essence. Therefore the relations are not really distinguished from each other.

Obj. 2: Further, as paternity and filiation are by name distinguished from the divine essence, so likewise are goodness and power. But this kind of distinction does not make any real distinction of the divine goodness and power. Therefore neither does it make any real distinction of paternity and filiation.

Obj. 3: Further, in God there is no real distinction but that of origin. But one relation does not seem to arise from another. Therefore the relations are not really distinguished from each other.

On the contrary, Boethius says (De Trin.) that in God "the substance contains the unity; and relation multiplies the trinity." Therefore, if the relations were not really distinguished from each other, there would be no real trinity in God, but only an ideal trinity, which is the error of Sabellius.

I answer that, The attributing of anything to another involves the attribution likewise of whatever is contained in it. So when "man" is attributed to anyone, a rational nature is likewise attributed to him. The idea of relation, however, necessarily means regard of one to another, according as one is relatively opposed to another. So as in God there is a real relation (A. 1), there must also be a real opposition. The very nature of relative opposition includes distinction. Hence, there must be real distinction in God, not, indeed, according to that which is absolute--namely, essence, wherein there is supreme unity and simplicity--but according to that which is relative.

Reply Obj. 1: According to the Philosopher (Phys. iii), this argument holds, that whatever things are identified with the same thing are identified with each other, if the identity be real and logical; as, for instance, a tunic and a garment; but not if they differ logically. Hence in the same place he says that although action is the same as motion, and likewise passion; still it does not follow that action and passion are the same; because action implies reference as of something "from which" there is motion in the thing moved; whereas passion implies reference as of something "which is from" another. Likewise, although paternity, just as filiation, is really the same as the divine essence; nevertheless these two in their own proper idea and definitions import opposite respects. Hence they are distinguished from each other.

Reply Obj. 2: Power and goodness do not import any opposition in their respective natures; and hence there is no parallel argument.

Reply Obj. 3: Although relations, properly speaking, do not arise or proceed from each other, nevertheless they are considered as opposed according to the procession of one from another. _____________________

FOURTH ARTICLE [I, Q. 28, Art. 3]

Whether in God There Are Only Four Real Relations--Paternity, Filiation, Spiration, and Procession?

Objection 1: It would seem that in God there are not only four real relations--paternity, filiation, spiration and procession. For it must be observed that in God there exist the relations of the intelligent agent to the object understood; and of the one willing to the object willed; which are real relations not comprised under those above specified. Therefore there are not only four real relations in God.

Obj. 2: Further, real relations in God are understood as coming from the intelligible procession of the Word. But intelligible relations are infinitely multiplied, as Avicenna says. Therefore in God there exists an infinite series of real relations.

Obj. 3: Further, ideas in God are eternal (Q. 15, A. 1); and are only distinguished from each other by reason of their regard to things, as above stated. Therefore in God there are many more eternal relations.

Obj. 4: Further, equality, and likeness, and identity are relations: and they are in God from eternity. Therefore several more relations are eternal in God than the above named.

Obj. 5: Further, it may also contrariwise be said that there are fewer relations in God than those above named. For, according to the Philosopher (Phys. iii text 24), "It is the same way from Athens to Thebes, as from Thebes to Athens." By the same way of reasoning there is the same relation from the Father to the Son, that of paternity, and from the Son to the Father, that of filiation; and thus there are not four relations in God.

I answer that, According to the Philosopher (Metaph. v), every relation is based either on quantity, as double and half; or on action and passion, as the doer and the deed, the father and the son, the master and the servant, and the like. Now as there is no quantity in God, for He is great without quantity, as Augustine says (De Trin. i, 1) it follows that a real relation in God can be based only on action. Such relations are not based on the actions of God according to any extrinsic procession, forasmuch as the relations of God to creatures are not real in Him (Q. 13, A. 7). Hence, it follows that real relations in God can be understood only in regard to those actions according to which there are internal, and not external, processions in God. These processions are two only, as above explained (Q. 27, A. 5), one derived from the action of the intellect, the procession of the Word; and the other from the action of the will, the procession of love. In respect of each of these processions two opposite relations arise; one of which is the relation of the person proceeding from the principle; the other is the relation of the principle Himself. The procession of the Word is called generation in the proper sense of the term, whereby it is applied to living things. Now the relation of the principle of generation in perfect living beings is called paternity; and the relation of the one proceeding from the principle is called filiation. But the procession of Love has no proper name of its own (Q. 27, A. 4); and so neither have the ensuing relations a proper name of their own. The relation of the principle of this procession is called spiration; and the relation of the person proceeding is called procession: although these two names belong to the processions or origins themselves, and not to the relations.

Reply Obj. 1: In those things in which there is a difference between the intellect and its object, and the will and its object, there can be a real relation, both of science to its object, and of the willer to the object willed. In God, however, the intellect and its object are one and the same; because by understanding Himself, God understands all other things; and the same applies to His will and the object that He wills. Hence it follows that in God these kinds of relations are not real; as neither is the relation of a thing to itself. Nevertheless, the relation to the word is a real relation; because the word is understood as proceeding by an intelligible action; and not as a thing understood. For when we understand a stone; that which the intellect conceives from the thing understood, is called the word.

Reply Obj. 2: Intelligible relations in ourselves are infinitely multiplied, because a man understands a stone by one act, and by another act understands that he understands the stone, and again by another, understands that he understands this; thus the acts of understanding are infinitely multiplied, and consequently also the relations understood. This does not apply to God, inasmuch as He understands all things by one act alone.

Reply Obj. 3: Ideal relations exist as understood by God. Hence it does not follow from their plurality that there are many relations in God; but that God knows these many relations.

Reply Obj. 4: Equality and similitude in God are not real relations; but are only logical relations (Q. 42, A. 3, ad 4).

Reply Obj. 5: The way from one term to another and conversely is the same; nevertheless the mutual relations are not the same. Hence, we cannot conclude that the relation of the father to the son is the same as that of the son to the father; but we could conclude this of something absolute, if there were such between them. _____________________

QUESTION 29

THE DIVINE PERSONS (In Four Articles)

Having premised what have appeared necessary notions concerning the processions and the relations, we must now approach the subject of the persons.

First, we shall consider the persons absolutely, and then comparatively as regards each other. We must consider the persons absolutely first in common; and then singly.

The general consideration of the persons seemingly involves four points:

(1) The signification of this word "person";

(2) the number of the persons;

(3) what is involved in the number of persons, or is opposed thereto; as diversity, and similitude, and the like; and

(4) what belongs to our knowledge of the persons.

Four subjects of inquiry are comprised in the first point:

(1) The definition of "person."

(2) The comparison of person to essence, subsistence, and hypostasis.

(3) Whether the name of person is becoming to God?

(4) What does it signify in Him? _____________________

FIRST ARTICLE [I, Q. 29, Art. 1]

The Definition of "Person"

Objection 1: It would seem that the definition of person given by Boethius (De Duab. Nat.) is insufficient--that is, "a person is an individual substance of a rational nature." For nothing singular can be subject to definition. But "person" signifies something singular. Therefore person is improperly defined.

Obj. 2: Further, substance as placed above in the definition of person, is either first substance, or second substance. If it is the former, the word "individual" is superfluous, because first substance is individual substance; if it stands for second substance, the word "individual" is false, for there is contradiction of terms; since second substances are the genera or species. Therefore this definition is incorrect.

Obj. 3: Further, an intentional term must not be included in the definition of a thing. For to define a man as "a species of animal" would not be a correct definition; since man is the name of a thing, and species is a name of an intention. Therefore, since person is the name of a thing (for it signifies a substance of a rational nature), the word "individual" which is an intentional name comes improperly into the definition.

Obj. 4: Further, "Nature is the principle of motion and rest, in those things in which it is essentially, and not accidentally," as Aristotle says (Phys. ii). But person exists in things immovable, as in God, and in the angels. Therefore the word "nature" ought not to enter into the definition of person, but the word should rather be "essence."

Obj. 5: Further, the separated soul is an individual substance of the rational nature; but it is not a person. Therefore person is not properly defined as above.

I answer that, Although the universal and particular exist in every genus, nevertheless, in a certain special way, the individual belongs to the genus of substance. For substance is individualized by itself; whereas the accidents are individualized by the subject, which is the substance; since this particular whiteness is called "this," because it exists in this particular subject. And so it is reasonable that the individuals of the genus substance should have a special name of their own; for they are called "hypostases," or first substances.

Further still, in a more special and perfect way, the particular and the individual are found in the rational substances which have dominion over their own actions; and which are not only made to act, like others; but which can act of themselves; for actions belong to singulars. Therefore also the individuals of the rational nature have a special name even among other substances; and this name is "person."

Thus the term "individual substance" is placed in the definition of person, as signifying the singular in the genus of substance; and the term "rational nature" is added, as signifying the singular in rational substances.

Reply Obj. 1: Although this or that singular may not be definable, yet what belongs to the general idea of singularity can be defined; and so the Philosopher (De Praedic., cap. De substantia) gives a definition of first substance; and in this way Boethius defines person.

Reply Obj. 2: In the opinion of some, the term "substance" in the definition of person stands for first substance, which is the hypostasis; nor is the term "individual" superfluously added, forasmuch as by the name of hypostasis or first substance the idea of universality and of part is excluded. For we do not say that man in general is an hypostasis, nor that the hand is since it is only a part. But where "individual" is added, the idea of assumptibility is excluded from person; for the human nature in Christ is not a person, since it is assumed by a greater--that is, by the Word of God. It is, however, better to say that substance is here taken in a general sense, as divided into first and second, and when "individual" is added, it is restricted to first substance.

Reply Obj. 3: Substantial differences being unknown to us, or at least unnamed by us, it is sometimes necessary to use accidental differences in the place of substantial; as, for example, we may say that fire is a simple, hot, and dry body: for proper accidents are the effects of substantial forms, and make them known. Likewise, terms expressive of intention can be used in defining realities if used to signify things which are unnamed. And so the term "individual" is placed in the definition of person to signify the mode of subsistence which belongs to particular substances.

Reply Obj. 4: According to the Philosopher (Metaph. v, 5), the word "nature" was first used to signify the generation of living things, which is called nativity. And because this kind of generation comes from an intrinsic principle, this term is extended to signify the intrinsic principle of any kind of movement. In this sense he defines "nature" (Phys. ii, 3). And since this kind of principle is either formal or material, both matter and form are commonly called nature. And as the essence of anything is completed by the form; so the essence of anything, signified by the definition, is commonly called nature. And here nature is taken in that sense. Hence Boethius says (De Duab. Nat.) that, "nature is the specific difference giving its form to each thing," for the specific difference completes the definition, and is derived from the special form of a thing. So in the definition of "person," which means the singular in a determined genus, it is more correct to use the term "nature" than "essence," because the latter is taken from being, which is most common.

Reply Obj. 5: The soul is a part of the human species; and so, although it may exist in a separate state, yet since it ever retains its nature of unibility, it cannot be called an individual substance, which is the hypostasis or first substance, as neither can the hand nor any other part of man; thus neither the definition nor the name of person belongs to it. _____________________

SECOND ARTICLE [I, Q. 29, Art. 2]

Whether "Person" Is the Same As Hypostasis, Subsistence, and Essence?

Objection 1: It would seem that "person" is the same as "hypostasis," "subsistence," and "essence." For Boethius says (De Duab. Nat.) that "the Greeks called the individual substance of the rational nature by the name hypostasis." But this with us signifies "person." Therefore "person" is altogether the same as "hypostasis."

Obj. 2: Further, as we say there are three persons in God, so we say there are three subsistences in God; which implies that "person" and "subsistence" have the same meaning. Therefore "person" and "subsistence" mean the same.

Obj. 3: Further, Boethius says (Com. Praed.) that the Greek ousia,which means essence, signifies a being composed of matter and form. Now that which is composed of matter and form is the individual substance called "hypostasis" and "person." Therefore all the aforesaid names seem to have the same meaning.

Obj. 4: On the contrary, Boethius says (De Duab. Nat.) that genera and species only subsist; whereas individuals are not only subsistent, but also substand. But subsistences are so called from subsisting, as substance or hypostasis is so called from substanding. Therefore, since genera and species are not hypostases or persons, these are not the same as subsistences.

Obj. 5: Further, Boethius says (Com. Praed.) that matter is called hypostasis, and form is called ousiosis--that is, subsistence. But neither form nor matter can be called person. Therefore person differs from the others.

I answer that, According to the Philosopher (Metaph. v), substance is twofold. In one sense it means the quiddity of a thing, signified by its definition, and thus we say that the definition means the substance of a thing; in which sense substance is called by the Greeks ousia, what we may call "essence." In another sense substance means a subject or suppositum, which subsists in the genus of substance. To this, taken in a general sense, can be applied a name expressive of an intention; and thus it is called suppositum. It is also called by three names signifying a reality--that is, "a thing of nature," "subsistence," and "hypostasis," according to a threefold consideration of the substance thus named. For, as it exists in itself and not in another, it is called "subsistence"; as we say that those things subsist which exist in themselves, and not in another. As it underlies some common nature, it is called "a thing of nature"; as, for instance, this particular man is a human natural thing. As it underlies the accidents, it is called "hypostasis," or "substance." What these three names signify in common to the whole genus of substances, this name "person" signifies in the genus of rational substances.

Reply Obj. 1: Among the Greeks the term "hypostasis," taken in the strict interpretation of the word, signifies any individual of the genus substance; but in the usual way of speaking, it means the individual of the rational nature, by reason of the excellence of that nature.

Reply Obj. 2: As we say "three persons" plurally in God, and "three subsistences," so the Greeks say "three hypostases." But because the word "substance," which, properly speaking, corresponds in meaning to "hypostasis," is used among us in an equivocal sense, since it sometimes means essence, and sometimes means hypostasis, in order to avoid any occasion of error, it was thought preferable to use "subsistence" for hypostasis, rather than "substance."

Reply Obj. 3: Strictly speaking, the essence is what is expressed by the definition. Now, the definition comprises the principles of the species, but not the individual principles. Hence in things composed of matter and form, the essence signifies not only the form, nor only the matter, but what is composed of matter and the common form, as the principles of the species. But what is composed of this matter and this form has the nature of hypostasis and person. For soul, flesh, and bone belong to the nature of man; whereas this soul, this flesh and this bone belong to the nature of this man. Therefore hypostasis and person add the individual principles to the idea of essence; nor are these identified with the essence in things composed of matter and form, as we said above when treating of divine simplicity (Q. 3, A. 3).

Reply Obj. 4: Boethius says that genera and species subsist, inasmuch as it belongs to some individual things to subsist, from the fact that they belong to genera and species comprised in the predicament of substance, but not because the species and genera themselves subsist; except in the opinion of Plato, who asserted that the species of things subsisted separately from singular things. To substand, however, belongs to the same individual things in relation to the accidents, which are outside the essence of genera and species.

Reply Obj. 5: The individual composed of matter and form substands in relation to accident from the very nature of matter. Hence Boethius says (De Trin.): "A simple form cannot be a subject." Its self-subsistence is derived from the nature of its form, which does not supervene to the things subsisting, but gives actual existence to the matter and makes it subsist as an individual. On this account, therefore, he ascribes hypostasis to matter, and ousiosis, or subsistence, to the form, because the matter is the principle of substanding, and form is the principle of subsisting. _____________________

THIRD ARTICLE [I, Q. 29, Art. 3]

Whether the Word "Person" Should Be Said of God?

Objection 1: It would seem that the name "person" should not be said of God. For Dionysius says (Div. Nom.): "No one should ever dare to say or think anything of the supersubstantial and hidden Divinity, beyond what has been divinely expressed to us by the oracles." But the name "person" is not expressed to us in the Old or New Testament. Therefore "person" is not to be applied to God.

Obj. 2: Further, Boethius says (De Duab. Nat.): "The word person seems to be taken from those persons who represented men in comedies and tragedies. For person comes from sounding through [personando], since a greater volume of sound is produced through the cavity in the mask. These "persons" or masks the Greeks called prosopa, as they were placed on the face and covered the features before the eyes." This, however, can apply to God only in a metaphorical sense. Therefore the word "person" is only applied to God metaphorically.

Obj. 3: Further, every person is a hypostasis. But the word "hypostasis" does not apply to God, since, as Boethius says (De Duab. Nat.), it signifies what is the subject of accidents, which do not exist in God. Jerome also says (Ep. ad Damas.) that, "in this word hypostasis, poison lurks in honey." Therefore the word "person" should not be said of God.

Obj. 4: Further, if a definition is denied of anything, the thing defined is also denied of it. But the definition of "person," as given above, does not apply to God. Both because reason implies a discursive knowledge, which does not apply to God, as we proved above (Q. 14, A. 12); and thus God cannot be said to have "a rational nature." And also because God cannot be called an individual substance, since the principle of individuation is matter; while God is immaterial: nor is He the subject of accidents, so as to be called a substance. Therefore the word "person" ought not to be attributed to God.

On the contrary, In the Creed of Athanasius we say: "One is the person of the Father, another of the Son, another of the Holy Ghost."

I answer that, "Person" signifies what is most perfect in all nature--that is, a subsistent individual of a rational nature. Hence, since everything that is perfect must be attributed to God, forasmuch as His essence contains every perfection, this name "person" is fittingly applied to God; not, however, as it is applied to creatures, but in a more excellent way; as other names also, which, while giving them to creatures, we attribute to God; as we showed above when treating of the names of God (Q. 13, A. 2).

Reply Obj. 1: Although the word "person" is not found applied to God in Scripture, either in the Old or New Testament, nevertheless what the word signifies is found to be affirmed of God in many places of Scripture; as that He is the supreme self-subsisting being, and the most perfectly intelligent being. If we could speak of God only in the very terms themselves of Scripture, it would follow that no one could speak about God in any but the original language of the Old or New Testament. The urgency of confuting heretics made it necessary to find new words to express the ancient faith about God. Nor is such a kind of novelty to be shunned; since it is by no means profane, for it does not lead us astray from the sense of Scripture. The Apostle warns us to avoid "profane novelties of words" (1 Tim. 6:20).

Reply Obj. 2: Although this name "person" may not belong to God as regards the origin of the term, nevertheless it excellently belongs to God in its objective meaning. For as famous men were represented in comedies and tragedies, the name "person" was given to signify those who held high dignity. Hence, those who held high rank in the Church came to be called "persons." Thence by some the definition of person is given as "hypostasis distinct by reason of dignity." And because subsistence in a rational nature is of high dignity, therefore every individual of the rational nature is called a "person." Now the dignity of the divine nature excels every other dignity; and thus the name "person" pre-eminently belongs to God.

Reply Obj. 3: The word "hypostasis" does not apply to God as regards its source of origin, since He does not underlie accidents; but it applies to Him in its objective sense, for it is imposed to signify the subsistence. Jerome said that "poison lurks in this word," forasmuch as before it was fully understood by the Latins, the heretics used this term to deceive the simple, to make people profess many essences as they profess several hypostases, inasmuch as the word "substance," which corresponds to hypostasis in Greek, is commonly taken amongst us to mean essence.

Reply Obj. 4: It may be said that God has a rational nature, if reason be taken to mean, not discursive thought, but in a general sense, an intelligent nature. But God cannot be called an "individual" in the sense that His individuality comes from matter; but only in the sense which implies incommunicability. "Substance" can be applied to God in the sense of signifying self-subsistence. There are some, however, who say that the definition of Boethius, quoted above (A. 1), is not a definition of person in the sense we use when speaking of persons in God. Therefore Richard of St. Victor amends this definition by adding that "Person" in God is "the incommunicable existence of the divine nature." _____________________

FOURTH ARTICLE [I, Q. 29, Art. 4]

Whether This Word "Person" Signifies Relation?

Objection 1: It would seem that this word "person," as applied to God, does not signify relation, but substance. For Augustine says (De Trin. vii, 6): "When we speak of the person of the Father, we mean nothing else but the substance of the Father, for person is said in regard to Himself, and not in regard to the Son."

Obj. 2: Further, the interrogation "What?" refers to essence. But, as Augustine says: "When we say there are three who bear witness in heaven, the Father, the Word, and the Holy Ghost, and it is asked, Three what? the answer is, Three persons." Therefore person signifies essence.

Obj. 3: According to the Philosopher (Metaph. iv), the meaning of a word is its definition. But the definition of "person" is this: "The individual substance of the rational nature," as above stated. Therefore "person" signifies substance.

Obj. 4: Further, person in men and angels does not signify relation, but something absolute. Therefore, if in God it signified relation, it would bear an equivocal meaning in God, in man, and in angels.

On the contrary, Boethius says (De Trin.) that "every word that refers to the persons signifies relation." But no word belongs to person more strictly than the very word "person" itself. Therefore this word "person" signifies relation.

I answer that, A difficulty arises concerning the meaning of this word "person" in God, from the fact that it is predicated plurally of the Three in contrast to the nature of the names belonging to the essence; nor does it in itself refer to another, as do the words which express relation.

Hence some have thought that this word "person" of itself expresses absolutely the divine essence; as this name "God" and this word "Wise"; but that to meet heretical attack, it was ordained by conciliar decree that it was to be taken in a relative sense, and especially in the plural, or with the addition of a distinguishing adjective; as when we say, "Three persons," or, "one is the person of the Father, another of the Son," etc. Used, however, in the singular, it may be either absolute or relative. But this does not seem to be a satisfactory explanation; for, if this word "person," by force of its own signification, expresses the divine essence only, it follows that forasmuch as we speak of "three persons," so far from the heretics being silenced, they had still more reason to argue. Seeing this, others maintained that this word "person" in God signifies both the essence and the relation. Some of these said that it signifies directly the essence, and relation indirectly, forasmuch as "person" means as it were "by itself one" [per se una]; and unity belongs to the essence. And what is "by itself" implies relation indirectly; for the Father is understood to exist "by Himself," as relatively distinct from the Son. Others, however, said, on the contrary, that it signifies relation directly; and essence indirectly; forasmuch as in the definition of "person" the term nature is mentioned indirectly; and these come nearer to the truth.

To determine the question, we must consider that something may be included in the meaning of a less common term, which is not included in the more common term; as "rational" is included in the meaning of "man," and not in the meaning of "animal." So that it is one thing to ask the meaning of the word animal, and another to ask its meaning when the animal in question is man. Also, it is one thing to ask the meaning of this word "person" in general; and another to ask the meaning of "person" as applied to God. For "person" in general signifies the individual substance of a rational figure. The individual in itself is undivided, but is distinct from others. Therefore "person" in any nature signifies what is distinct in that nature: thus in human nature it signifies this flesh, these bones, and this soul, which are the individuating principles of a man, and which, though not belonging to "person" in general, nevertheless do belong to the meaning of a particular human person.

Now distinction in God is only by relation of origin, as stated above (Q. 28, AA. 2, 3), while relation in God is not as an accident in a subject, but is the divine essence itself; and so it is subsistent, for the divine essence subsists. Therefore, as the Godhead is God so the divine paternity is God the Father, Who is a divine person. Therefore a divine person signifies a relation as subsisting. And this is to signify relation by way of substance, and such a relation is a hypostasis subsisting in the divine nature, although in truth that which subsists in the divine nature is the divine nature itself. Thus it is true to say that the name "person" signifies relation directly, and the essence indirectly; not, however, the relation as such, but as expressed by way of a hypostasis. So likewise it signifies directly the essence, and indirectly the relation, inasmuch as the essence is the same as the hypostasis: while in God the hypostasis is expressed as distinct by the relation: and thus relation, as such, enters into the notion of the person indirectly. Thus we can say that this signification of the word "person" was not clearly perceived before it was attacked by heretics. Hence, this word "person" was used just as any other absolute term. But afterwards it was applied to express relation, as it lent itself to that signification, so that this word "person" means relation not only by use and custom, according to the first opinion, but also by force of its own proper signification.

Reply Obj. 1: This word "person" is said in respect to itself, not to another; forasmuch as it signifies relation not as such, but by way of a substance--which is a hypostasis. In that sense Augustine says that it signifies the essence, inasmuch as in God essence is the same as the hypostasis, because in God what He is, and whereby He is are the same.

Reply Obj. 2: The term "what" refers sometimes to the nature expressed by the definition, as when we ask; What is man? and we answer: A mortal rational animal. Sometimes it refers to the suppositum, as when we ask, What swims in the sea? and answer, A fish. So to those who ask, Three what? we answer, Three persons.

Reply Obj. 3: In God the individual--i.e. distinct and incommunicable substance--includes the idea of relation, as above explained.

Reply Obj. 4: The different sense of the less common term does not produce equivocation in the more common. Although a horse and an ass have their own proper definitions, nevertheless they agree univocally in animal, because the common definition of animal applies to both. So it does not follow that, although relation is contained in the signification of divine person, but not in that of an angelic or of a human person, the word "person" is used in an equivocal sense. Though neither is it applied univocally, since nothing can be said univocally of God and creatures (Q. 13, A. 5). _____________________

QUESTION 30

THE PLURALITY OF PERSONS IN GOD (In Four Articles)

We are now led to consider the plurality of the persons: about which there are four points of inquiry:

(1) Whether there are several persons in God?

(2) How many are they?

(3) What the numeral terms signify in God?

(4) The community of the term "person." _____________________

FIRST ARTICLE [I, Q. 30, Art. 1]

Whether There Are Several Persons in God?

Objection 1: It would seem that there are not several persons in God. For person is "the individual substance of a rational nature." If then there are several persons in God, there must be several substances; which appears to be heretical.

Obj. 2: Further, Plurality of absolute properties does not make a distinction of persons, either in God, or in ourselves. Much less therefore is this effected by a plurality of relations. But in God there is no plurality but of relations (Q. 28, A. 3). Therefore there cannot be several persons in God.

Obj. 3: Further, Boethius says of God (De Trin. i), that "this is truly one which has no number." But plurality implies number. Therefore there are not several persons in God.

Obj. 4: Further, where number is, there is whole and part. Thus, if in God there exist a number of persons, there must be whole and part in God; which is inconsistent with the divine simplicity.

On the contrary, Athanasius says: "One is the person of the Father, another of the Son, another of the Holy Ghost." Therefore the Father, and the Son, and the Holy Ghost are several persons.

I answer that, It follows from what precedes that there are several persons in God. For it was shown above (Q. 29, A. 4) that this word "person" signifies in God a relation as subsisting in the divine nature. It was also established (Q. 28, A. 1) that there are several real relations in God; and hence it follows that there are also several realities subsistent in the divine nature; which means that there are several persons in God.

Reply Obj. 1: The definition of "person" includes "substance," not as meaning the essence, but the suppositum which is made clear by the addition of the term "individual." To signify the substance thus understood, the Greeks use the name "hypostasis." So, as we say, "Three persons," they say "Three hypostases." We are not, however, accustomed to say Three substances, lest we be understood to mean three essences or natures, by reason of the equivocal signification of the term.

Reply Obj. 2: The absolute properties in God, such as goodness and wisdom, are not mutually opposed; and hence, neither are they really distinguished from each other. Therefore, although they subsist, nevertheless they are not several subsistent realities--that is, several persons. But the absolute properties in creatures do not subsist, although they are really distinguished from each other, as whiteness and sweetness; on the other hand, the relative properties in God subsist, and are really distinguished from each other (Q. 28, A. 3). Hence the plurality of persons in God.

Reply Obj. 3: The supreme unity and simplicity of God exclude every kind of plurality of absolute things, but not plurality of relations. Because relations are predicated relatively, and thus the relations do not import composition in that of which they are predicated, as Boethius teaches in the same book.

Reply Obj. 4: Number is twofold, simple or absolute, as two and three and four; and number as existing in things numbered, as two men and two horses. So, if number in God is taken absolutely or abstractedly, there is nothing to prevent whole and part from being in Him, and thus number in Him is only in our way of understanding; forasmuch as number regarded apart from things numbered exists only in the intellect. But if number be taken as it is in the things numbered, in that sense as existing in creatures, one is part of two, and two of three, as one man is part of two men, and two of three; but this does not apply to God, because the Father is of the same magnitude as the whole Trinity, as we shall show further on (Q. 42, AA. 1, 4). _____________________

SECOND ARTICLE [I, Q. 30, Art. 2]

Whether There Are More Than Three Persons in God?

Objection 1: It would seem that there are more than three persons in God. For the plurality of persons in God arises from the plurality of the relative properties as stated above (A. 1). But there are four relations in God as stated above (Q. 28, A. 4), paternity, filiation, common spiration, and procession. Therefore there are four persons in God.

Obj. 2: The nature of God does not differ from His will more than from His intellect. But in God, one person proceeds from the will, as love; and another proceeds from His nature, as Son. Therefore another proceeds from His intellect, as Word, besides the one Who proceeds from His nature, as Son; thus again it follows that there are not only three persons in God.

Obj. 3: Further, the more perfect a creature is, the more interior operations it has; as a man has understanding and will beyond other animals. But God infinitely excels every creature. Therefore in God not only is there a person proceeding from the will, and another from the intellect, but also in an infinite number of ways. Therefore there are an infinite number of persons in God.

Obj. 4: Further, it is from the infinite goodness of the Father that He communicates Himself infinitely in the production of a divine person. But also in the Holy Ghost is infinite goodness. Therefore the Holy Ghost produces a divine person; and that person another; and so to infinity.

Obj. 5: Further, everything within a determinate number is measured, for number is a measure. But the divine persons are immense, as we say in the Creed of Athanasius: "The Father is immense, the Son is immense, the Holy Ghost is immense." Therefore the persons are not contained within the number three.

On the contrary, It is said: "There are three who bear witness in heaven, the Father, the Word, and the Holy Ghost" (1 John 5:7). To those who ask, "Three what?" we answer, with Augustine (De Trin. vii, 4), "Three persons." Therefore there are but three persons in God.

I answer that, As was explained above, there can be only three persons in God. For it was shown above that the several persons are the several subsisting relations really distinct from each other. But a real distinction between the divine relations can come only from relative opposition. Therefore two opposite relations must needs refer to two persons: and if any relations are not opposite they must needs belong to the same person. Since then paternity and filiation are opposite relations, they belong necessarily to two persons. Therefore the subsisting paternity is the person of the Father; and the subsisting filiation is the person of the Son. The other two relations are not opposed to each other; therefore these two cannot belong to one person: hence either one of them must belong to both of the aforesaid persons; or one must belong to one person, and the other to the other. Now, procession cannot belong to the Father and the Son, or to either of them; for thus it would follows that the procession of the intellect, which in God is generation, wherefrom paternity and filiation are derived, would issue from the procession of love, whence spiration and procession are derived, if the person generating and the person generated proceeded from the person spirating; and this is against what was laid down above (Q. 27, AA. 3, 4). We must consequently admit that spiration belongs to the person of the Father, and to the person of the Son, forasmuch as it has no relative opposition either to paternity or to filiation; and consequently that procession belongs to the other person who is called the person of the Holy Ghost, who proceeds by way of love, as above explained. Therefore only three persons exist in God, the Father, the Son, and the Holy Ghost.

Reply Obj. 1: Although there are four relations in God, one of them, spiration, is not separated from the person of the Father and of the Son, but belongs to both; thus, although it is a relation, it is not called a property, because it does not belong to only one person; nor is it a personal relation--i.e. constituting a person. The three relations--paternity, filiation, and procession--are called personal properties, constituting as it were the persons; for paternity is the person of the Father, filiation is the person of the Son, procession is the person of the Holy Ghost proceeding.

Reply Obj. 2: That which proceeds by way of intelligence, as word, proceeds according to similitude, as also that which proceeds by way of nature; thus, as above explained (Q. 27, A. 3), the procession of the divine Word is the very same as generation by way of nature. But love, as such, does not proceed as the similitude of that whence it proceeds; although in God love is co-essential as being divine; and therefore the procession of love is not called generation in God.

Reply Obj. 3: As man is more perfect than other animals, he has more intrinsic operations than other animals, because his perfection is something composite. Hence the angels, who are more perfect and more simple, have fewer intrinsic operations than man, for they have no imagination, or feeling, or the like. In God there exists only one real operation--that is, His essence. How there are in Him two processions was above explained (Q. 27, AA. 1, 4).

Reply Obj. 4: This argument would prove if the Holy Ghost possessed another goodness apart from the goodness of the Father; for then if the Father produced a divine person by His goodness, the Holy Ghost also would do so. But the Father and the Holy Ghost have one and the same goodness. Nor is there any distinction between them except by the personal relations. So goodness belongs to the Holy Ghost, as derived from another; and it belongs to the Father, as the principle of its communication to another. The opposition of relation does not allow the relation of the Holy Ghost to be joined with the relation of principle of another divine person; because He Himself proceeds from the other persons who are in God.

Reply Obj. 5: A determinate number, if taken as a simple number, existing in the mind only, is measured by one. But when we speak of a number of things as applied to the persons in God, the notion of measure has no place, because the magnitude of the three persons is the same (Q. 42, AA. 1, 4), and the same is not measured by the same. _____________________

THIRD ARTICLE [I, Q. 30, Art. 3]

Whether the Numeral Terms Denote Anything Real in God?

Objection 1: It would seem that the numeral terms denote something real in God. For the divine unity is the divine essence. But every number is unity repeated. Therefore every numeral term in God signifies the essence; and therefore it denotes something real in God.

Obj. 2: Further, whatever is said of God and of creatures, belongs to God in a more eminent manner than to creatures. But the numeral terms denote something real in creatures; therefore much more so in God.

Obj. 3: Further, if the numeral terms do not denote anything real in God, and are introduced simply in a negative and removing sense, as plurality is employed to remove unity, and unity to remove plurality; it follows that a vicious circle results, confusing the mind and obscuring the truth; and this ought not to be. Therefore it must be said that the numeral terms denote something real in God.

On the contrary, Hilary says (De Trin. iv): "If we admit companionship"--that is, plurality--"we exclude the idea of oneness and of solitude;" and Ambrose says (De Fide i): "When we say one God, unity excludes plurality of gods, and does not imply quantity in God." Hence we see that these terms are applied to God in order to remove something; and not to denote anything positive.

I answer that, The Master (Sent. i, D, 24) considers that the numeral terms do not denote anything positive in God, but have only a negative meaning. Others, however, assert the contrary.

In order to resolve this point, we may observe that all plurality is a consequence of division. Now division is twofold; one is material, and is division of the continuous; from this results number, which is a species of quantity. Number in this sense is found only in material things which have quantity. The other kind of division is called formal, and is effected by opposite or diverse forms; and this kind of division results in a multitude, which does not belong to a genus, but is transcendental in the sense in which being is divided by one and by many. This kind of multitude is found only in immaterial things.

Some, considering only that multitude which is a species of discrete quantity, and seeing that such kind of quantity has no place in God, asserted that the numeral terms do not denote anything real in God, but remove something from Him. Others, considering the same kind of multitude, said that as knowledge exists in God according to the strict sense of the word, but not in the sense of its genus (as in God there is no such thing as a quality), so number exists in God in the proper sense of number, but not in the sense of its genus, which is quantity.

But we say that numeral terms predicated of God are not derived from number, a species of quantity, for in that sense they could bear only a metaphorical sense in God, like other corporeal properties, such as length, breadth, and the like; but that they are taken from multitude in a transcendent sense. Now multitude so understood has relation to the many of which it is predicated, as "one" convertible with "being" is related to being; which kind of oneness does not add anything to being, except a negation of division, as we saw when treating of the divine unity (Q. 11, A. 1); for "one" signifies undivided being. So, of whatever we say "one," we imply its undivided reality: thus, for instance, "one" applied to man signifies the undivided nature or substance of a man. In the same way, when we speak of many things, multitude in this latter sense points to those things as being each undivided in itself.

But number, if taken as a species of quantity, denotes an accident added to being; as also does "one" which is the principle of that number. Therefore the numeral terms in God signify the things of which they are said, and beyond this they add negation only, as stated (Sent. i, D, 24); in which respect the Master was right (Sent. i, D, 24). So when we say, the essence is one, the term "one" signifies the essence undivided; and when we say the person is one, it signifies the person undivided; and when we say the persons are many, we signify those persons, and their individual undividedness; for it is of the very nature of multitude that it should be composed of units.

Reply Obj. 1: One, as it is a transcendental, is wider and more general than substance and relation. And so likewise is multitude; hence in God it may mean both substance and relation, according to the context. Still, the very signification of such names adds a negation of division, beyond substance and relation; as was explained above.

Reply Obj. 2: Multitude, which denotes something real in creatures, is a species of quantity, and cannot be used when speaking of God: unlike transcendental multitude, which adds only indivision to those of which it is predicated. Such a kind of multitude is applicable to God.

Reply Obj. 3: "One" does not exclude multitude, but division, which logically precedes one or multitude. Multitude does not remove unity, but division from each of the individuals which compose the multitude. This was explained when we treated of the divine unity (Q. 11, A. 2).

It must be observed, nevertheless, that the opposite arguments do not sufficiently prove the point advanced. Although the idea of solitude is excluded by plurality, and the plurality of gods by unity, it does not follow that these terms express this signification alone. For blackness is excluded by whiteness; nevertheless, the term whiteness does not signify the mere exclusion of blackness. _____________________

FOURTH ARTICLE [I, Q. 30, Art. 4]

Whether This Term "Person" Can Be Common to the Three Persons?

Objection 1: It would seem that this term "person" cannot be common to the three persons. For nothing is common to the three persons but the essence. But this term "person" does not signify the essence directly. Therefore it is not common to all three.

Obj. 2: Further, the common is the opposite to the incommunicable. But the very meaning of person is that it is incommunicable; as appears from the definition given by Richard of St. Victor (Q. 29, A. 3, ad 4). Therefore this term "person" is not common to all the three persons.

Obj. 3: Further, if the name "person" is common to the three, it is common either really, or logically. But it is not so really; otherwise the three persons would be one person; nor again is it so logically; otherwise person would be a universal. But in God there is neither universal nor particular; neither genus nor species, as we proved above (Q. 3, A. 5). Therefore this term 'person' is not common to the three.

On the contrary, Augustine says (De Trin. vii, 4) that when we ask, "Three what?" we say, "Three persons," because what a person is, is common to them.

I answer that, The very mode of expression itself shows that this term "person" is common to the three when we say "three persons"; for when we say "three men" we show that "man" is common to the three. Now it is clear that this is not community of a real thing, as if one essence were common to the three; otherwise there would be only one person of the three, as also one essence.

What is meant by such a community has been variously determined by those who have examined the subject. Some have called it a community of exclusion, forasmuch as the definition of "person" contains the word "incommunicable." Others thought it to be a community of intention, as the definition of person contains the word "individual"; as we say that to be a species is common to horse and ox. Both of these explanations, however, are excluded by the fact that "person" is not a name of exclusion nor of intention, but the name of a reality. We must therefore resolve that even in human affairs this name "person" is common by a community of idea, not as genus or species, but as a vague individual thing. The names of genera and species, as man or animal, are given to signify the common natures themselves, but not the intentions of those common natures, signified by the terms genus or species. The vague individual thing, as "some man," signifies the common nature with the determinate mode of existence of singular things--that is, something self-subsisting, as distinct from others. But the name of a designated singular thing signifies that which distinguishes the determinate thing; as the name Socrates signifies this flesh and this bone. But there is this difference--that the term "some man" signifies the nature, or the individual on the part of its nature, with the mode of existence of singular things; while this name "person" is not given to signify the individual on the part of the nature, but the subsistent reality in that nature. Now this is common in idea to the divine persons, that each of them subsists distinctly from the others in the divine nature. Thus this name "person" is common in idea to the three divine persons.

Reply Obj. 1: This argument is founded on a real community.

Reply Obj. 2: Although person is incommunicable, yet the mode itself of incommunicable existence can be common to many.

Reply Obj. 3: Although this community is logical and not real, yet it does not follow that in God there is universal or particular, or genus, or species; both because neither in human affairs is the community of person the same as community of genus or species; and because the divine persons have one being; whereas genus and species and every other universal are predicated of many which differ in being. _____________________

QUESTION 31

OF WHAT BELONGS TO THE UNITY OR PLURALITY IN GOD (In Four Articles)

We now consider what belongs to the unity or plurality in God; which gives rise to four points of inquiry:

(1) Concerning the word "Trinity";

(2) Whether we can say that the Son is other than the Father?

(3) Whether an exclusive term, which seems to exclude otherness, can be joined to an essential name in God?

(4) Whether it can be joined to a personal term? _____________________

FIRST ARTICLE [I, Q. 31, Art. 1]

Whether There Is Trinity in God?

Objection 1: It would seem there is not trinity in God. For every name in God signifies substance or relation. But this name "Trinity" does not signify the substance; otherwise it would be predicated of each one of the persons: nor does it signify relation; for it does not express a name that refers to another. Therefore the word "Trinity" is not to be applied to God.

Obj. 2: Further, this word "trinity" is a collective term, since it signifies multitude. But such a word does not apply to God; as the unity of a collective name is the least of unities, whereas in God there exists the greatest possible unity. Therefore this word "trinity" does not apply to God.

Obj. 3: Further, every trine is threefold. But in God there is not triplicity; since triplicity is a kind of inequality. Therefore neither is there trinity in God.

Obj. 4: Further, all that exists in God exists in the unity of the divine essence; because God is His own essence. Therefore, if Trinity exists in God, it exists in the unity of the divine essence; and thus in God there would be three essential unities; which is heresy.

Obj. 5: Further, in all that is said of God, the concrete is predicated of the abstract; for Deity is God and paternity is the Father. But the Trinity cannot be called trine; otherwise there would be nine realities in God; which, of course, is erroneous. Therefore the word trinity is not to be applied to God.

On the contrary, Athanasius says: "Unity in Trinity; and Trinity in Unity is to be revered."

I answer that, The name "Trinity" in God signifies the determinate number of persons. And so the plurality of persons in God requires that we should use the word trinity; because what is indeterminately signified by plurality, is signified by trinity in a determinate manner.

Reply Obj. 1: In its etymological sense, this word "Trinity" seems to signify the one essence of the three persons, according as trinity may mean trine-unity. But in the strict meaning of the term it rather signifies the number of persons of one essence; and on this account we cannot say that the Father is the Trinity, as He is not three persons. Yet it does not mean the relations themselves of the Persons, but rather the number of persons related to each other; and hence it is that the word in itself does not express regard to another.

Reply Obj. 2: Two things are implied in a collective term, plurality of the supposita, and a unity of some kind of order. For "people" is a multitude of men comprehended under a certain order. In the first sense, this word "trinity" is like other collective words; but in the second sense it differs from them, because in the divine Trinity not only is there unity of order, but also with this there is unity of essence.

Reply Obj. 3: "Trinity" is taken in an absolute sense; for it signifies the threefold number of persons. "Triplicity" signifies a proportion of inequality; for it is a species of unequal proportion, according to Boethius (Arithm. i, 23). Therefore in God there is not triplicity, but Trinity.

Reply Obj. 4: In the divine Trinity is to be understood both number and the persons numbered. So when we say, "Trinity in Unity," we do not place number in the unity of the essence, as if we meant three times one; but we place the Persons numbered in the unity of nature; as the supposita of a nature are said to exist in that nature. On the other hand, we say "Unity in Trinity"; meaning that the nature is in its supposita.

Reply Obj. 5: When we say, "Trinity is trine," by reason of the number implied, we signify the multiplication of that number by itself; since the word trine imports a distinction in the suppositaof which it is spoken. Therefore it cannot be said that the Trinity is trine; otherwise it follows that, if the Trinity be trine, there would be three supposita of the Trinity; as when we say, "God is trine," it follows that there are three supposita of the Godhead. _____________________

SECOND ARTICLE [I, Q. 31, Art. 2]

Whether the Son Is Other Than the Father?

Objection 1: It would seem that the Son is not other than the Father. For "other" is a relative term implying diversity of substance. If, then, the Son is other than the Father, He must be different from the Father; which is contrary to what Augustine says (De Trin. vii), that when we speak of three persons, "we do not mean to imply diversity."

Obj. 2: Further, whosoever are other from one another, differ in some way from one another. Therefore, if the Son is other than the Father, it follows that He differs from the Father; which is against what Ambrose says (De Fide i), that "the Father and the Son are one in Godhead; nor is there any difference in substance between them, nor any diversity."

Obj. 3: Further, the term alien is taken from alius (other). But the Son is not alien from the Father, for Hilary says (De Trin. vii) that "in the divine persons there is nothing diverse, nothing alien, nothing separable." Therefore the Son is not other than the Father.

Obj. 4: Further, the terms "other person" and "other thing" [alius et aliud] have the same meaning, differing only in gender. So if the Son is another person from the Father, it follows that the Son is a thing apart from the Father.

On the contrary, Augustine [*Fulgentius, De Fide ad Petrum i.] says: "There is one essence of the Father and Son and Holy Ghost, in which the Father is not one thing, the Son another, and the Holy Ghost another; although the Father is one person, the Son another, and the Holy Ghost another."

I answer that, Since as Jerome remarks [*In substance, Ep. lvii.], a heresy arises from words wrongly used, when we speak of the Trinity we must proceed with care and with befitting modesty; because, as Augustine says (De Trin. i, 3), "nowhere is error more harmful, the quest more toilsome, the finding more fruitful." Now, in treating of the Trinity, we must beware of two opposite errors, and proceed cautiously between them--namely, the error of Arius, who placed a Trinity of substance with the Trinity of persons; and the error of Sabellius, who placed unity of person with the unity of essence.

Thus, to avoid the error of Arius we must shun the use of the terms diversity and difference in God, lest we take away the unity of essence: we may, however, use the term "distinction" on account of the relative opposition. Hence whenever we find terms of "diversity" or "difference" of Persons used in an authentic work, these terms of "diversity" or "difference" are taken to mean "distinction." But lest the simplicity and singleness of the divine essence be taken away, the terms "separation" and "division," which belong to the parts of a whole, are to be avoided: and lest quality be taken away, we avoid the use of the term "disparity": and lest we remove similitude, we avoid the terms "alien" and "discrepant." For Ambrose says (De Fide i) that "in the Father and the Son there is no discrepancy, but one Godhead": and according to Hilary, as quoted above, "in God there is nothing alien, nothing separable."

To avoid the heresy of Sabellius, we must shun the term "singularity," lest we take away the communicability of the divine essence. Hence Hilary says (De Trin. vii): "It is sacrilege to assert that the Father and the Son are separate in Godhead." We must avoid the adjective "only" (unici) lest we take away the number of persons. Hence Hilary says in the same book: "We exclude from God the idea of singularity or uniqueness." Nevertheless, we say "the only Son," for in God there is no plurality of Sons. Yet, we do not say "the only God," for the Deity is common to several. We avoid the word "confused," lest we take away from the Persons the order of their nature. Hence Ambrose says (De Fide i): "What is one is not confused; and there is no multiplicity where there is no difference." The word "solitary" is also to be avoided, lest we take away the society of the three persons; for, as Hilary says (De Trin. iv), "We confess neither a solitary nor a diverse God."

This word "other" [alius], however, in the masculine sense, means only a distinction of suppositum; and hence we can properly say that "the Son is other than the Father," because He is another suppositum of the divine nature, as He is another person and another hypostasis.

Reply Obj. 1: "Other," being like the name of a particular thing, refers to the suppositum; and so, there is sufficient reason for using it, where there is a distinct substance in the sense of hypostasis or person. But diversity requires a distinct substance in the sense of essence. Thus we cannot say that the Son is diverse from the Father, although He is another.

Reply Obj. 2: "Difference" implies distinction of form. There is one form in God, as appears from the text, "Who, when He was in the form of God" (Phil. 2:6). Therefore the term "difference" does not properly apply to God, as appears from the authority quoted. Yet, Damascene (De Fide Orth. i, 5) employs the term "difference" in the divine persons, as meaning that the relative property is signified by way of form. Hence he says that the hypostases do not differ from each other in substance, but according to determinate properties. But "difference" is taken for "distinction," as above stated.

Reply Obj. 3: The term "alien" means what is extraneous and dissimilar; which is not expressed by the term "other" [alius]; and therefore we say that the Son is "other" than the Father, but not that He is anything "alien."

Reply Obj. 4: The neuter gender is formless; whereas the masculine is formed and distinct; and so is the feminine. So the common essence is properly and aptly expressed by the neuter gender, but by the masculine and feminine is expressed the determined subject in the common nature. Hence also in human affairs, if we ask, Who is this man? we answer, Socrates, which is the name of the suppositum; whereas, if we ask, What is he? we reply, A rational and mortal animal. So, because in God distinction is by the persons, and not by the essence, we say that the Father is other than the Son, but not something else; while conversely we say that they are one thing, but not one person. _____________________

THIRD ARTICLE [I, Q. 31, Art. 3]

Whether the Exclusive Word "Alone" Should Be Added to the Essential Term in God?

Objection 1: It would seem that the exclusive word "alone" [solus] is not to be added to an essential term in God. For, according to the Philosopher (Elench. ii, 3), "He is alone who is not with another." But God is with the angels and the souls of the saints. Therefore we cannot say that God is alone.

Obj. 2: Further, whatever is joined to the essential term in God can be predicated of every person per se, and of all the persons together; for, as we can properly say that God is wise, we can say the Father is a wise God; and the Trinity is a wise God. But Augustine says (De Trin. vi, 9): "We must consider the opinion that the Father is not true God alone." Therefore God cannot be said to be alone.

Obj. 3: Further if this expression "alone" is joined to an essential term, it would be so joined as regards either the personal predicate or the essential predicate. But it cannot be the former, as it is false to say, "God alone is Father," since man also is a father; nor, again, can it be applied as regards the latter, for, if this saying were true, "God alone creates," it would follow that the "Father alone creates," as whatever is said of God can be said of the Father; and it would be false, as the Son also creates. Therefore this expression "alone" cannot be joined to an essential term in God.

On the contrary, It is said, "To the King of ages, immortal, invisible, the only God" (1 Tim. 1:17).

I answer that, This term "alone" can be taken as a categorematical term, or as a syncategorematical term. A categorematical term is one which ascribes absolutely its meaning to a given suppositum; as, for instance, "white" to man, as when we say a "white man." If the term "alone" is taken in this sense, it cannot in any way be joined to any term in God; for it would mean solitude in the term to which it is joined; and it would follow that God was solitary, against what is above stated (A. 2). A syncategorematical term imports the order of the predicate to the subject; as this expression "every one" or "no one"; and likewise the term "alone," as excluding every other suppositum from the predicate. Thus, when we say, "Socrates alone writes," we do not mean that Socrates is solitary, but that he has no companion in writing, though many others may be with him. In this way nothing prevents the term "alone" being joined to any essential term in God, as excluding the predicate from all things but God; as if we said "God alone is eternal," because nothing but God is eternal.

Reply Obj. 1: Although the angels and the souls of the saints are always with God, nevertheless, if plurality of persons did not exist in God, He would be alone or solitary. For solitude is not removed by association with anything that is extraneous in nature; thus anyone is said to be alone in a garden, though many plants and animals are with him in the garden. Likewise, God would be alone or solitary, though angels and men were with Him, supposing that several persons were not within Him. Therefore the society of angels and of souls does not take away absolute solitude from God; much less does it remove respective solitude, in reference to a predicate.

Reply Obj. 2: This expression "alone," properly speaking, does not affect the predicate, which is taken formally, for it refers to the suppositum, as excluding any other suppositum from the one which it qualifies. But the adverb "only," being exclusive, can be applied either to subject or predicate. For we can say, "Only Socrates"--that is, no one else--"runs: and Socrates runs only"--that is, he does nothing else. Hence it is not properly said that the Father is God alone, or the Trinity is God alone, unless some implied meaning be assumed in the predicate, as, for instance, "The Trinity is God Who alone is God." In that sense it can be true to say that the Father is that God Who alone is God, if the relative be referred to the predicate, and not to the suppositum. So, when Augustine says that the Father is not God alone, but that the Trinity is God alone, he speaks expositively, as he might explain the words, "To the King of ages, invisible, the only God," as applying not to the Father, but to the Trinity alone.

Reply Obj. 3: In both ways can the term "alone" be joined to an essential term. For this proposition, "God alone is Father," can mean two things, because the word "Father" can signify the person of the Father; and then it is true; for no man is that person: or it can signify that relation only; and thus it is false, because the relation of paternity is found also in others, though not in a univocal sense. Likewise it is true to say God alone creates; nor, does it follow, "therefore the Father alone creates," because, as logicians say, an exclusive diction so fixes the term to which it is joined that what is said exclusively of that term cannot be said exclusively of an individual contained in that term: for instance, from the premiss, "Man alone is a mortal rational animal," we cannot conclude, "therefore Socrates alone is such." _____________________

FOURTH ARTICLE [I, Q. 31, Art. 4]

Whether an Exclusive Diction Can Be Joined to the Personal Term?

Objection 1: It would seem that an exclusive diction can be joined to the personal term, even though the predicate is common. For our Lord speaking to the Father, said: "That they may know Thee, the only true God" (John 17:3). Therefore the Father alone is true God.

Obj. 2: Further, He said: "No one knows the Son but the Father" (Matt. 11:27); which means that the Father alone knows the Son. But to know the Son is common (to the persons). Therefore the same conclusion follows.

Obj. 3: Further, an exclusive diction does not exclude what enters into the concept of the term to which it is joined. Hence it does not exclude the part, nor the universal; for it does not follow that if we say "Socrates alone is white," that therefore "his hand is not white," or that "man is not white." But one person is in the concept of another; as the Father is in the concept of the Son; and conversely. Therefore, when we say, The Father alone is God, we do not exclude the Son, nor the Holy Ghost; so that such a mode of speaking is true.

Obj. 4: Further, the Church sings: "Thou alone art Most High, O Jesus Christ."

On the contrary, This proposition "The Father alone is God" includes two assertions--namely, that the Father is God, and that no other besides the Father is God. But this second proposition is false, for the Son is another from the Father, and He is God. Therefore this is false, The Father alone is God; and the same of the like sayings.

I answer that, When we say, "The Father alone is God," such a proposition can be taken in several senses. If "alone" means solitude in the Father, it is false in a categorematical sense; but if taken in a syncategorematical sense it can again be understood in several ways. For if it exclude (all others) from the form of the subject, it is true, the sense being "the Father alone is God"--that is, "He who with no other is the Father, is God." In this way Augustine expounds when he says (De Trin. vi, 6): "We say the Father alone, not because He is separate from the Son, or from the Holy Ghost, but because they are not the Father together with Him." This, however, is not the usual way of speaking, unless we understand another implication, as though we said "He who alone is called the Father is God." But in the strict sense the exclusion affects the predicate. And thus the proposition is false if it excludes another in the masculine sense; but true if it excludes it in the neuter sense; because the Son is another person than the Father, but not another thing; and the same applies to the Holy Ghost. But because this diction "alone," properly speaking, refers to the subject, it tends to exclude another Person rather than other things. Hence such a way of speaking is not to be taken too literally, but it should be piously expounded, whenever we find it in an authentic work.

Reply Obj. 1: When we say, "Thee the only true God," we do not understand it as referring to the person of the Father, but to the whole Trinity, as Augustine expounds (De Trin. vi, 9). Or, if understood of the person of the Father, the other persons are not excluded by reason of the unity of essence; in so far as the word "only" excludes another thing, as above explained.

The same Reply can be given to Obj. 2. For an essential term applied to the Father does not exclude the Son or the Holy Ghost, by reason of the unity of essence. Hence we must understand that in the text quoted the term "no one" [*Nemo = non-homo, i.e. no man] is not the same as "no man," which the word itself would seem to signify (for the person of the Father could not be excepted), but is taken according to the usual way of speaking in a distributive sense, to mean any rational nature.

Reply Obj. 3: The exclusive diction does not exclude what enters into the concept of the term to which it is adjoined, if they do not differ in suppositum, as part and universal. But the Son differs in suppositum from the Father; and so there is no parity.

Reply Obj. 4: We do not say absolutely that the Son alone is Most High; but that He alone is Most High "with the Holy Ghost, in the glory of God the Father." _____________________

QUESTION 32

THE KNOWLEDGE OF THE DIVINE PERSONS (In Four Articles)

We proceed to inquire concerning the knowledge of the divine persons; and this involves four points of inquiry:

(1) Whether the divine persons can be known by natural reason?

(2) Whether notions are to be attributed to the divine persons?

(3) The number of the notions?

(4) Whether we may lawfully have various contrary opinions of these notions? _____________________

FIRST ARTICLE [I, Q. 32, Art. 1]

Whether the Trinity of the Divine Persons Can Be Known by Natural Reason?

Objection 1: It would seem that the trinity of the divine persons can be known by natural reason. For philosophers came to the knowledge of God not otherwise than by natural reason. Now we find that they said many things about the trinity of persons, for Aristotle says (De Coelo et Mundo i, 2): "Through this number"--namely, three--"we bring ourselves to acknowledge the greatness of one God, surpassing all things created." And Augustine says (Confess. vii, 9): "I have read in their works, not in so many words, but enforced by many and various reasons, that in the beginning was the Word, and the Word was with God, and the Word was God," and so on; in which passage the distinction of persons is laid down. We read, moreover, in a gloss on Rom. 1 and Ex. 8 that the magicians of Pharaoh failed in the third sign--that is, as regards knowledge of a third person--i.e. of the Holy Ghost--and thus it is clear that they knew at least two persons. Likewise Trismegistus says: "The monad begot a monad, and reflected upon itself its own heat." By which words the generation of the Son and procession of the Holy Ghost seem to be indicated. Therefore knowledge of the divine persons can be obtained by natural reason.

Obj. 2: Further, Richard St. Victor says (De Trin. i, 4): "I believe without doubt that probable and even necessary arguments can be found for any explanation of the truth." So even to prove the Trinity some have brought forward a reason from the infinite goodness of God, who communicates Himself infinitely in the procession of the divine persons; while some are moved by the consideration that "no good thing can be joyfully possessed without partnership." Augustine proceeds (De Trin. x, 4; x, 11, 12) to prove the trinity of persons by the procession of the word and of love in our own mind; and we have followed him in this (Q. 27, AA. 1, 3). Therefore the trinity of persons can be known by natural reason.

Obj. 3: Further, it seems to be superfluous to teach what cannot be known by natural reason. But it ought not to be said that the divine tradition of the Trinity is superfluous. Therefore the trinity of persons can be known by natural reason.

On the contrary, Hilary says (De Trin. i), "Let no man think to reach the sacred mystery of generation by his own mind." And Ambrose says (De Fide ii, 5), "It is impossible to know the secret of generation. The mind fails, the voice is silent." But the trinity of the divine persons is distinguished by origin of generation and procession (Q. 30, A. 2). Since, therefore, man cannot know, and with his understanding grasp that for which no necessary reason can be given, it follows that the trinity of persons cannot be known by reason.

I answer that, It is impossible to attain to the knowledge of the Trinity by natural reason. For, as above explained (Q. 12, AA. 4, 12), man cannot obtain the knowledge of God by natural reason except from creatures. Now creatures lead us to the knowledge of God, as effects do to their cause. Accordingly, by natural reason we can know of God that only which of necessity belongs to Him as the principle of things, and we have cited this fundamental principle in treating of God as above (Q. 12, A. 12). Now, the creative power of God is common to the whole Trinity; and hence it belongs to the unity of the essence, and not to the distinction of the persons. Therefore, by natural reason we can know what belongs to the unity of the essence, but not what belongs to the distinction of the persons. Whoever, then, tries to prove the trinity of persons by natural reason, derogates from faith in two ways. Firstly, as regards the dignity of faith itself, which consists in its being concerned with invisible things, that exceed human reason; wherefore the Apostle says that "faith is of things that appear not" (Heb. 11:1), and the same Apostle says also, "We speak wisdom among the perfect, but not the wisdom of this world, nor of the princes of this world; but we speak the wisdom of God in a mystery which is hidden" (1 Cor. 2:6, 7). Secondly, as regards the utility of drawing others to the faith. For when anyone in the endeavor to prove the faith brings forward reasons which are not cogent, he falls under the ridicule of the unbelievers: since they suppose that we stand upon such reasons, and that we believe on such grounds.

Therefore, we must not attempt to prove what is of faith, except by authority alone, to those who receive the authority; while as regards others it suffices to prove that what faith teaches is not impossible. Hence it is said by Dionysius (Div. Nom. ii): "Whoever wholly resists the word, is far off from our philosophy; whereas if he regards the truth of the word"--i.e. "the sacred word, we too follow this rule."

Reply Obj. 1: The philosophers did not know the mystery of the trinity of the divine persons by its proper attributes, such as paternity, filiation, and procession, according to the Apostle's words, "We speak the wisdom of God which none of the princes of the world"--i.e. the philosophers--"knew" (1 Cor. 2:6). Nevertheless, they knew some of the essential attributes appropriated to the persons, as power to the Father, wisdom to the Son, goodness to the Holy Ghost; as will later on appear. So, when Aristotle said, "By this number," etc., we must not take it as if he affirmed a threefold number in God, but that he wished to say that the ancients used the threefold number in their sacrifices and prayers on account of some perfection residing in the number three. In the Platonic books also we find, "In the beginning was the word," not as meaning the Person begotten in God, but as meaning the ideal type whereby God made all things, and which is appropriated to the Son. And although they knew these were appropriated to the three persons, yet they are said to have failed in the third sign--that is, in the knowledge of the third person, because they deviated from the goodness appropriated to the Holy Ghost, in that knowing God "they did not glorify Him as God" (Rom. 1); or, because the Platonists asserted the existence of one Primal Being whom they also declared to be the father of the universe, they consequently maintained the existence of another substance beneath him, which they called "mind" or the "paternal intellect," containing the idea of all things, as Macrobius relates (Som. Scip. iv). They did not, however, assert the existence of a third separate substance which might correspond to the Holy Ghost. So also we do not assert that the Father and the Son differ in substance, which was the error of Origen and Arius, who in this followed the Platonists. When Trismegistus says, "Monad begot monad," etc., this does not refer to the generation of the Son, or to the procession of the Holy Ghost, but to the production of the world. For one God produced one world by reason of His love for Himself.

Reply Obj. 2: Reason may be employed in two ways to establish a point: firstly, for the purpose of furnishing sufficient proof of some principle, as in natural science, where sufficient proof can be brought to show that the movement of the heavens is always of uniform velocity. Reason is employed in another way, not as furnishing a sufficient proof of a principle, but as confirming an already established principle, by showing the congruity of its results, as in astrology the theory of eccentrics and epicycles is considered as established, because thereby the sensible appearances of the heavenly movements can be explained; not, however, as if this proof were sufficient, forasmuch as some other theory might explain them. In the first way, we can prove that God is one; and the like. In the second way, reasons avail to prove the Trinity; as, when assumed to be true, such reasons confirm it. We must not, however, think that the trinity of persons is adequately proved by such reasons. This becomes evident when we consider each point; for the infinite goodness of God is manifested also in creation, because to produce from nothing is an act of infinite power. For if God communicates Himself by His infinite goodness, it is not necessary that an infinite effect should proceed from God: but that according to its own mode and capacity it should receive the divine goodness. Likewise, when it is said that joyous possession of good requires partnership, this holds in the case of one not having perfect goodness: hence it needs to share some other's good, in order to have the goodness of complete happiness. Nor is the image in our mind an adequate proof in the case of God, forasmuch as the intellect is not in God and ourselves univocally. Hence, Augustine says (Tract. xxvii. in Joan.) that by faith we arrive at knowledge, and not conversely.

Reply Obj. 3: There are two reasons why the knowledge of the divine persons was necessary for us. It was necessary for the right idea of creation. The fact of saying that God made all things by His Word excludes the error of those who say that God produced things by necessity. When we say that in Him there is a procession of love, we show that God produced creatures not because He needed them, nor because of any other extrinsic reason, but on account of the love of His own goodness. So Moses, when he had said, "In the beginning God created heaven and earth," subjoined, "God said, Let there be light," to manifest the divine Word; and then said, "God saw the light that it was good," to show proof of the divine love. The same is also found in the other works of creation. In another way, and chiefly, that we may think rightly concerning the salvation of the human race, accomplished by the Incarnate Son, and by the gift of the Holy Ghost. _____________________

SECOND ARTICLE [I, Q. 32, Art. 2]

Whether There Are Notions in God?

Objection 1: It would seem that in God there are no notions. For Dionysius says (Div. Nom. i): "We must not dare to say anything of God but what is taught to us by the Holy Scripture." But Holy Scripture does not say anything concerning notions. Therefore there are none in God.

Obj. 2: Further, all that exists in God concerns the unity of the essence or the trinity of the persons. But the notions do not concern the unity of the essence, nor the trinity of the persons; for neither can what belongs to the essence be predicated of the notions: for instance, we do not say that paternity is wise or creates; nor can what belongs to the persons be so predicated; for example, we do not say that paternity begets, nor that filiation is begotten. Therefore there do not exist notions in God.

Obj. 3: Further, we do not require to presuppose any abstract notions as principles of knowing things which are devoid of composition: for they are known of themselves. But the divine persons are supremely simple. Therefore we are not to suppose any notions in God.

On the contrary, Damascene says (De Fide Orth. iii, 5): "We recognize difference of hypostases [i.e. of persons], in the three properties; i.e. in the paternal, the filial, and the processional." Therefore we must admit properties and notions in God.

I answer that, Prepositivus, considering the simplicity of the persons, said that in God there were no properties or notions, and wherever there were mentioned, he propounded the abstract for the concrete. For as we are accustomed to say, "I beseech your kindness"--i.e. you who are kind--so when we speak of paternity in God, we mean God the Father.

But, as shown above (Q. 3, A. 3, ad 1), the use of concrete and abstract names in God is not in any way repugnant to the divine simplicity; forasmuch as we always name a thing as we understand it. Now, our intellect cannot attain to the absolute simplicity of the divine essence, considered in itself, and therefore, our human intellect apprehends and names divine things, according to its own mode, that is in so far as they are found in sensible objects, whence its knowledge is derived. In these things we use abstract terms to signify simple forms; and to signify subsistent things we use concrete terms. Hence also we signify divine things, as above stated, by abstract names, to express their simplicity; whereas, to express their subsistence and completeness, we use concrete names.

But not only must essential names be signified in the abstract and in the concrete, as when we say Deity and God; or wisdom and wise; but the same applies to the personal names, so that we may say paternity and Father.

Two chief motives for this can be cited. The first arises from the obstinacy of heretics. For since we confess the Father, the Son, and the Holy Ghost to be one God and three persons, to those who ask: "Whereby are They one God? and whereby are They three persons?" as we answer that They are one in essence or deity; so there must also be some abstract terms whereby we may answer that the persons are distinguished; and these are the properties or notions signified by an abstract term, as paternity and filiation. Therefore the divine essence is signified as "What"; and the person as "Who"; and the property as "Whereby."

The second motive is because one person in God is related to two persons--namely, the person of the Father to the person of the Son and the person of the Holy Ghost. This is not, however, by one relation; otherwise it would follow that the Son also and the Holy Ghost would be related to the Father by one and the same relation. Thus, since relation alone multiplies the Trinity, it would follow that the Son and the Holy Ghost would not be two persons. Nor can it be said with Prepositivus that as God is related in one way to creatures, while creatures are related to Him in divers ways, so the Father is related by one relation to the Son and to the Holy Ghost; whereas these two persons are related to the Father by two relations. For, since the very specific idea of a relation is that it refers to another, it must be said that two relations are not specifically different if but one opposite relation corresponds to them. For the relation of lord and father must differ according to the difference of filiation and servitude. Now, all creatures are related to God as His creatures by one specific relation. But the Son and the Holy Ghost are not related to the Father by one and the same kind of relation. Hence there is no parity.

Further, in God there is no need to admit any real relation to the creature (Q. 28, A. 1, 3); while there is no reason against our admitting in God, many logical relations. But in the Father there must be a real relation to the Son and to the Holy Ghost. Hence, corresponding to the two relations of the Son and of the Holy Ghost, whereby they are related to the Father, we must understand two relations in the Father, whereby He is related to the Son and to the Holy Ghost. Hence, since there is only one Person of the Father, it is necessary that the relations should be separately signified in the abstract; and these are what we mean by properties and notions.

Reply Obj. 1: Although the notions are not mentioned in Holy Scripture, yet the persons are mentioned, comprising the idea of notions, as the abstract is contained in the concrete.

Reply Obj. 2: In God the notions have their significance not after the manner of realities, but by way of certain ideas whereby the persons are known; although in God these notions or relations are real, as stated above (Q. 28, A. 1). Therefore whatever has order to any essential or personal act, cannot be applied to the notions; forasmuch as this is against their mode of signification. Hence we cannot say that paternity begets, or creates, or is wise, or is intelligent. The essentials, however, which are not ordered to any act, but simply remove created conditions from God, can be predicated of the notions; for we can say that paternity is eternal, or immense, or such like. So also on account of the real identity, substantive terms, whether personal or essential, can be predicated of the notions; for we can say that paternity is God, and that paternity is the Father.

Reply Obj. 3: Although the persons are simple, still without prejudice to their simplicity, the proper ideas of the persons can be abstractedly signified, as above explained. _____________________
