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
manifest
