FOURTH ARTICLE [I, Q. 41, Art. 4]

Whether in God There Is a Power in Respect of the Notional Acts?

Objection 1: It would seem that in God there is no power in respect

of the notional acts. For every kind of power is either active or

passive; neither of which can be here applied, there being in God

nothing which we call passive power, as above explained (Q. 25, A.

1); nor can active power belong to one person as regards another,

since the divine persons were not made, as stated above (A. 3).

Therefore in God there is no power in respect of the notional acts.

Obj. 2: Further, the object of power is what is possible. But the

divine persons are not regarded as possible, but necessary.

Therefore, as regards the notional acts, whereby the divine persons

proceed, there cannot be power in God.

Obj. 3: Further, the Son proceeds as the word, which is the concept

of the intellect; and the Holy Ghost proceeds as love, which belongs

to the will. But in God power exists as regards effects, and not as

regards intellect and will, as stated above (Q. 25, A. 1). Therefore,

in God power does not exist in reference to the notional acts.

_On the contrary,_ Augustine says (Contra Maxim. iii, 1): "If God the

Father could not beget a co-equal Son, where is the omnipotence of

God the Father?" Power therefore exists in God regarding the notional

acts.

_I answer that,_ As the notional acts exist in God, so must there be

also a power in God regarding these acts; since power only means the

principle of act. So, as we understand the Father to be principle of

generation; and the Father and the Son to be the principle of

spiration, we must attribute the power of generating to the Father,

and the power of spiration to the Father and the Son; for the power

of generation means that whereby the generator generates. Now every

generator generates by something. Therefore in every generator we

must suppose the power of generating, and in the spirator the power

of spirating.

Reply Obj. 1: As a person, according to notional acts, does not

proceed as if made; so the power in God as regards the notional acts

has no reference to a person as if made, but only as regards the

person as proceeding.

Reply Obj. 2: Possible, as opposed to what is necessary, is a

consequence of a passive power, which does not exist in God. Hence,

in God there is no such thing as possibility in this sense, but only

in the sense of possible as contained in what is necessary; and in

this latter sense it can be said that as it is possible for God to

be, so also is it possible that the Son should be generated.

Reply Obj. 3: Power signifies a principle: and a principle implies

distinction from that of which it is the principle. Now we must

observe a double distinction in things said of God: one is a real

distinction, the other is a distinction of reason only. By a real

distinction, God by His essence is distinct from those things of

which He is the principle by creation: just as one person is distinct

from the other of which He is principle by a notional act. But in God

the distinction of action and agent is one of reason only, otherwise

action would be an accident in God. And therefore with regard to

those actions in respect of which certain things proceed which are

distinct from God, either personally or essentially, we may ascribe

power to God in its proper sense of principle. And as we ascribe to

God the power of creating, so we may ascribe the power of begetting

and of spirating. But "to understand" and "to will" are not such

actions as to designate the procession of something distinct from

God, either essentially or personally. Wherefore, with regard to

these actions we cannot ascribe power to God in its proper sense, but

only after our way of understanding and speaking: inasmuch as we

designate by different terms the intellect and the act of

understanding in God, whereas in God the act of understanding is His

very essence which has no principle.
