Q: Objection 1: It would seem that in God the essence is not the same as person. For whenever essence is the same as person or
suppositum,
there can be only one
suppositum
of one nature, as is clear in the case of all separate substances. For in those things which are really one and the same, one cannot be multiplied apart from the other. But in God there is one essence and three persons, as is clear from what is above expounded (Q. 28, A. 3; Q. 30, A. 2). Therefore essence is not the same as person.

Obj. 2: Further, simultaneous affirmation and negation of the same things in the same respect cannot be true. But affirmation and negation are true of essence and of person. For person is distinct, whereas essence is not. Therefore person and essence are not the same.

Obj. 3: Further, nothing can be subject to itself. But person is subject to essence; whence it is called
suppositum
or "hypostasis." Therefore person is not the same as essence.
Q: Objection 1: It would seem not right to say that the three persons are of one essence. For Hilary says (De Synod.) that the Father, Son and Holy Ghost "are indeed three by substance, but one in harmony." But the substance of God is His essence. Therefore the three persons are not of one essence.

Obj. 2: Further, nothing is to be affirmed of God except what can be confirmed by the authority of Holy Writ, as appears from Dionysius (Div. Nom. i). Now Holy Writ never says that the Father, Son and Holy Ghost are of one essence. Therefore this should not be asserted.

Obj. 3: Further, the divine nature is the same as the divine essence. It suffices therefore to say that the three persons are of one nature.

Obj. 4: Further, it is not usual to say that the person is of the essence; but rather that the essence is of the person. Therefore it does not seem fitting to say that the three persons are of one essence.

Obj. 5: Further, Augustine says (De Trin. vii, 6) that we do not say that the three persons are "from one essence [ex una essentia]," lest we should seem to indicate a distinction between the essence and the persons in God. But prepositions which imply transition, denote the oblique case. Therefore it is equally wrong to say that the three persons are "of one essence [unius essentiae]."

Obj. 6: Further, nothing should be said of God which can be occasion of error. Now, to say that the three persons are of one essence or substance, furnishes occasion of error. For, as Hilary says (De Synod.): "One substance predicated of the Father and the Son signifies either one subsistent, with two denominations; or one substance divided into two imperfect substances; or a third prior substance taken and assumed by the other two." Therefore it must not be said that the three persons are of one substance.
Q: Objection 1: It would seem that essential names, as the name "God," should not be predicated in the singular of the three persons, but in the plural. For as "man" signifies "one that has humanity," so God signifies "one that has Godhead." But the three persons are three who have Godhead. Therefore the three persons are "three Gods."

Obj. 2: Further, Gen. 1:1, where it is said, "In the beginning God created heaven and earth," the Hebrew original has "Elohim," which may be rendered "Gods" or "Judges": and this word is used on account of the plurality of persons. Therefore the three persons are "several Gods," and not "one" God.

Obj. 3: Further, this word "thing" when it is said absolutely, seems to belong to substance. But it is predicated of the three persons in the plural. For Augustine says (De Doctr. Christ. i, 5): "The things that are the objects of our future glory are the Father, Son and Holy Ghost." Therefore other essential names can be predicated in the plural of the three persons.

Obj. 4: Further, as this word "God" signifies "a being who has Deity," so also this word "person" signifies a being subsisting in an intellectual nature. But we say there are three persons. So for the same reason we can say there are "three Gods."
Q: Objection 1: It would seem that the concrete, essential names cannot stand for the person, so that we can truly say "God begot God." For, as the logicians say, "a singular term signifies what it stands for." But this name "God" seems to be a singular term, for it cannot be predicated in the plural, as above explained (A. 3). Therefore, since it signifies the essence, it stands for essence, and not for person.

Obj. 2: Further, a term in the subject is not modified by a term in the predicate, as to its signification; but only as to the sense signified in the predicate. But when I say, "God creates," this name "God" stands for the essence. So when we say "God begot," this term "God" cannot by reason of the notional predicate, stand for person.

Obj. 3: Further, if this be true, "God begot," because the Father generates; for the same reason this is true, "God does not beget," because the Son does not beget. Therefore there is God who begets, and there is God who does not beget; and thus it follows that there are two Gods.

Obj. 4: Further, if "God begot God," He begot either God, that is Himself, or another God. But He did not beget God, that is Himself; for, as Augustine says (De Trin. i, 1), "nothing begets itself." Neither did He beget another God; as there is only one God. Therefore it is false to say, "God begot God."

Obj. 5: Further, if "God begot God," He begot either God who is the Father, or God who is not the Father. If God who is the Father, then God the Father was begotten. If God who is not the Father, then there is a God who is not God the Father: which is false. Therefore it cannot be said that "God begot God."
Q: Objection 1: It would seem that abstract essential names can stand for the person, so that this proposition is true, "Essence begets essence." For Augustine says (De Trin. vii, i, 2): "The Father and the Son are one Wisdom, because they are one essence; and taken singly Wisdom is from Wisdom, as essence from essence."

Obj. 2: Further, generation or corruption in ourselves implies generation or corruption of what is within us. But the Son is generated. Therefore since the divine essence is in the Son, it seems that the divine essence is generated.

Obj. 3: Further, God and the divine essence are the same, as is clear from what is above explained (Q. 3, A. 3). But, as was shown, it is true to say that "God begets God." Therefore this is also true: "Essence begets essence."

Obj. 4: Further, a predicate can stand for that of which it is predicated. But the Father is the divine essence; therefore essence can stand for the person of the Father. Thus the essence begets.

Obj. 5: Further, the essence is "a thing begetting," because the essence is the Father who is begetting. Therefore if the essence is not begetting, the essence will be "a thing begetting," and "not begetting": which cannot be.

Obj. 6: Further, Augustine says (De Trin. iv, 20): "The Father is the principle of the whole Godhead." But He is principle only by begetting or spirating. Therefore the Father begets or spirates the Godhead.
Q: Whether the Persons Can Be Predicated of the Essential Terms?

A: On the contrary,
Augustine says, in his sermon on Faith [*Serm. ii, in coena Domini], "We believe that one God is one divinely named Trinity."

I answer that,
As above explained (A. 5), although adjectival terms, whether personal or notional, cannot be predicated of the essence, nevertheless substantive terms can be so predicated, owing to the real identity of essence and person. The divine essence is not only really the same as one person, but it is really the same as the three persons. Whence, one person, and two, and three, can be predicated of the essence as if we were to say, "The essence is the Father, and the Son, and the Holy Ghost." And because this word "God" can of itself stand for the essence, as above explained (A. 4, ad 3), hence, as it is true to say, "The essence is the three persons"; so likewise it is true to say, "God is the three persons."

Reply Obj. 1: As above explained this term "man" can of itself stand for person, whereas an adjunct is required for it to stand for the universal human nature. So it is false to say, "Man is every man"; because it cannot be verified of any particular human subject. On the contrary, this word "God" can of itself be taken for the divine essence. So, although to say of any of the
supposita
of the divine nature, "God is the Trinity," is untrue, nevertheless it is true of the divine essence. This was denied by Porretanus because he did not take note of this distinction.

Reply Obj. 2: When we say, "God," or "the divine essence is the Father," the predication is one of identity, and not of the lower in regard to a higher species: because in God there is no universal and singular. Hence, as this proposition, "The Father is God" is of itself true, so this proposition "God is the Father" is true of itself, and by no means accidentally.
Q: Objection 1: It would seem that the persons cannot be predicated of the concrete essential names; so that we can say for instance, "God is three persons"; or "God is the Trinity." For it is false to say, "man is every man," because it cannot be verified as regards any particular subject. For neither Socrates, nor Plato, nor anyone else is every man. In the same way this proposition, "God is the Trinity," cannot be verified of any one of the
supposita
of the divine nature. For the Father is not the Trinity; nor is the Son; nor is the Holy Ghost. So to say, "God is the Trinity," is false.

Obj. 2: Further, the lower is not predicated of the higher except by accidental predication; as when I say, "animal is man"; for it is accidental to animal to be man. But this name "God" as regards the three persons is as a general term to inferior terms, as Damascene says (De Fide Orth. iii, 4). Therefore it seems that the names of the persons cannot be predicated of this name "God," except in an accidental sense.
Q: Whether the Essential Names Should Be Appropriated to the Persons?

A: On the contrary,
the Apostle says: "Christ the power of God and the wisdom of God" (1 Cor. 1:24).

I answer that,
For the manifestation of our faith it is fitting that the essential attributes should be appropriated to the persons. For although the trinity of persons cannot be proved by demonstration, as was above expounded (Q. 32, A. 1), nevertheless it is fitting that it be declared by things which are more known to us. Now the essential attributes of God are more clear to us from the standpoint of reason than the personal properties; because we can derive certain knowledge of the essential attributes from creatures which are sources of knowledge to us, such as we cannot obtain regarding the personal properties, as was above explained (Q. 32, A. 1). As, therefore, we make use of the likeness of the trace or image found in creatures for the manifestation of the divine persons, so also in the same manner do we make use of the essential attributes. And such a manifestation of the divine persons by the use of the essential attributes is called "appropriation."

The divine person can be manifested in a twofold manner by the essential attributes; in one way by similitude, and thus the things which belong to the intellect are appropriated to the Son, Who proceeds by way of intellect, as Word. In another way by dissimilitude; as power is appropriated to the Father, as Augustine says, because fathers by reason of old age are sometimes feeble; lest anything of the kind be imagined of God.

Reply Obj. 1: The essential attributes are not appropriated to the persons as if they exclusively belonged to them; but in order to make the persons manifest by way of similitude, or dissimilitude, as above explained. So, no error in faith can arise, but rather manifestation of the truth.

Reply Obj. 2: If the essential attributes were appropriated to the persons as exclusively belonging to each of them, then it would follow that one person would be as a form as regards another; which Augustine altogether repudiates (De Trin. vi, 2), showing that the Father is wise, not by Wisdom begotten by Him, as though only the Son were Wisdom; so that the Father and the Son together only can be called wise, but not the Father without the Son. But the Son is called the Wisdom of the Father, because He is Wisdom from the Father Who is Wisdom. For each of them is of Himself Wisdom; and both together are one Wisdom. Whence the Father is not wise by the wisdom begotten by Him, but by the wisdom which is His own essence.

Reply Obj. 3: Although the essential attribute is in its proper concept prior to person, according to our way of understanding; nevertheless, so far as it is appropriated, there is nothing to prevent the personal property from being prior to that which is appropriated. Thus color is posterior to body considered as body, but is naturally prior to "white body," considered as white.
Q: Objection 1: It would seem that the essential names should not be appropriated to the persons. For whatever might verge on error in faith should be avoided in the treatment of divine things; for, as Jerome says, "careless words involve risk of heresy" [*In substance Ep. lvii.]. But to appropriate to any one person the names which are common to the three persons, may verge on error in faith; for it may be supposed either that such belong only to the person to whom they are appropriated or that they belong to Him in a fuller degree than to the others. Therefore the essential attributes should not be appropriated to the persons.

Obj. 2: Further, the essential attributes expressed in the abstract signify by mode of form. But one person is not as a form to another; since a form is not distinguished in subject from that of which it is the form. Therefore the essential attributes, especially when expressed in the abstract, are not to be appropriated to the persons.

Obj. 3: Further, property is prior to the appropriated, for property is included in the idea of the appropriated. But the essential attributes, in our way of understanding, are prior to the persons; as what is common is prior to what is proper. Therefore the essential attributes are not to be appropriated to the persons.
Q: Objection 1: It would seem that in God relation is not the same as person. For when things are identical, if one is multiplied the others are multiplied. But in one person there are several relations; as in the person of the Father there is paternity and common spiration. Again, one relation exists in two person, as common spiration in the Father and in the Son. Therefore relation is not the same as person.

Obj. 2: Further, according to the Philosopher (Phys. iv, text. 24), nothing is contained by itself. But relation is in the person; nor can it be said that this occurs because they are identical, for otherwise relation would be also in the essence. Therefore relation, or property, is not the same as person in God.

Obj. 3: Further, when several things are identical, what is predicated of one is predicated of the others. But all that is predicated of a Person is not predicated of His property. For we say that the Father begets; but not that the paternity is begetting. Therefore property is not the same as person in God.
Q: Objection 1: It would seem that the persons are not distinguished by the relations. For simple things are distinct by themselves. But the persons are supremely simple. Therefore they are distinguished by themselves, and not by the relation.

Obj. 2: Further, a form is distinguished only in relation to its genus. For white is distinguished from black only by quality. But "hypostasis" signifies an individual in the genus of substance. Therefore the hypostases cannot be distinguished by relations.

Obj. 3: Further, what is absolute comes before what is relative. But the distinction of the divine persons is the primary distinction. Therefore the divine persons are not distinguished by the relations.

Obj. 4: Further, whatever presupposes distinction cannot be the first principle of distinction. But relation presupposes distinction, which comes into its definition; for a relation is essentially what is towards another. Therefore the first distinctive principle in God cannot be relation.
Q: Objection 1: It would seem that the hypostases remain if the properties or relations are mentally abstracted from the persons. For that to which something is added, may be understood when the addition is taken away; as man is something added to animal which can be understood if rational be taken away. But person is something added to hypostasis; for person is "a hypostasis distinguished by a property of dignity." Therefore, if a personal property be taken away from a person, the hypostasis remains.

Obj. 2: Further, that the Father is Father, and that He is someone, are not due to the same reason. For as He is the Father by paternity, supposing He is some one by paternity, it would follow that the Son, in Whom there is not paternity, would not be "someone." So when paternity is mentally abstracted from the Father, He still remains "someone"--that is, a hypostasis. Therefore, if property be removed from person, the hypostasis remains.

Obj. 3: Further, Augustine says (De Trin. v, 6): "Unbegotten is not the same as Father; for if the Father had not begotten the Son, nothing would prevent Him being called unbegotten." But if He had not begotten the Son, there would be no paternity in Him. Therefore, if paternity be removed, there still remains the hypostasis of the Father as unbegotten.
Q: Whether the properties presuppose the notional acts?

A: On the contrary,
Generation is the operation of the person of the Father. But paternity constitutes the person of the Father. Therefore in the order of intelligence, paternity is prior to generation.

I answer that,
According to the opinion that the properties do not distinguish and constitute the hypostases in God, but only manifest them as already distinct and constituted, we must absolutely say that the relations in our mode of understanding follow upon the notional acts, so that we can say, without qualifying the phrase, that "because He begets, He is the Father." A distinction, however, is needed if we suppose that the relations distinguish and constitute the divine hypostases. For origin has in God an active and passive signification--active, as generation is attributed to the Father, and spiration, taken for the notional act, is attributed to the Father and the Son; passive, as nativity is attributed to the Son, and procession to the Holy Ghost. For, in the order of intelligence, origin, in the passive sense, simply precedes the personal properties of the person proceeding; because origin, as passively understood, signifies the way to a person constituted by the property. Likewise, origin signified actively is prior in the order of intelligence to the non-personal relation of the person originating; as the notional act of spiration precedes, in the order of intelligence, the unnamed relative property common to the Father and the Son. The personal property of the Father can be considered in a twofold sense: firstly, as a relation; and thus again in the order of intelligence it presupposes the notional act, for relation, as such, is founded upon an act: secondly, according as it constitutes the person; and thus the notional act presupposes the relation, as an action presupposes a person acting.

Reply Obj. 1: When the Master says that "because He begets, He is Father," the term "Father" is taken as meaning relation only, but not as signifying the subsisting person; for then it would be necessary to say conversely that because He is Father He begets.

Reply Obj. 2: This objection avails of paternity as a relation, but not as constituting a person.

Reply Obj. 3: Nativity is the way to the person of the Son; and so, in the order of intelligence, it precedes filiation, even as constituting the person of the Son. But active generation signifies a proceeding from the person of the Father; wherefore it presupposes the personal property of the Father.

QUESTION 41

OF THE PERSONS IN REFERENCE TO THE NOTIONAL ACTS (In Six Articles)

We now consider the persons in reference to the notional acts, concerning which six points of inquiry arise:

(1) Whether the notional acts are to be attributed to the persons?

(2) Whether these acts are necessary, or voluntary?

(3) Whether as regards these acts, a person proceeds from nothing or from something?

(4) Whether in God there exists a power as regards the notional acts?

(5) What this power means?

(6) Whether several persons can be the term of one notional act?
Q: Objection 1: It would seem that the notional acts are understood before the properties. For the Master of the Sentences says (Sent. i, D, xxvii) that "the Father always is, because He is ever begetting the Son." So it seems that generation precedes paternity in the order of intelligence.

Obj. 2: Further, in the order of intelligence every relation presupposes that on which it is founded; as equality presupposes quantity. But paternity is a relation founded on the action of generation. Therefore paternity presupposes generation.

Obj. 3: Further, active generation is to paternity as nativity is to filiation. But filiation presupposes nativity; for the Son is so called because He is born. Therefore paternity also presupposes generation.
