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 ( Question [3], Article [3]). Therefore, there is no power in God.
Objection 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.
Objection 4: Further, it was shown above ( Question [14], Article [8]; Question [19], Article [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 ( Question [3], Article [2]; Question [4], Articles [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 to Objection 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 to Objection 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 to Objection 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 to Objection 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.
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.
Objection 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.
Objection 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 ( Article [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 ( Question [7], Article [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 ( Question [7], Article [1]) it follows that His power likewise is infinite.
Reply to Objection 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 ( Question [7], Article [1]); and consequently so also His power. It does not follow, therefore, that it is imperfect.
Reply to Objection 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 ( Question [3], Article [5]; Question [4], Article [3]). Whence it follows that His effect is always less than His power. It is not necessary,
