There are those who imagine God to be like a man, composed of body and
soul and subject to passions; but it is clear enough from what has
already been demonstrated how far off men who believe this are from the
true knowledge of God. But these I dismiss, for all men who have in any
way looked into the divine nature deny that God is corporeal. That He
cannot be so they conclusively prove by showing that by "body" we
understand a certain quantity possessing length, breadth, and depth,
limited by some fixed form; and that to attribute these to God, a being
absolutely infinite, is the greatest absurdity. But yet at the same
time, from other arguments by which they endeavor to confirm their
proof, they clearly show that they remove altogether from the divine
nature substance itself corporeal or extended, affirming that it was
created by God. By what divine power, however, it could have been
created they are altogether ignorant, so that it is clear they do not
understand what they themselves say....

But I will refute my adversaries' arguments, which, taken altogether,
come to this. First, that corporeal substance, in so far as it is
substance, consists, as they suppose, of parts, and therefore they deny
that it can be infinite, and consequently that it can pertain to God.
This they illustrate by many examples, one or two of which I will
adduce. If corporeal substance, they say, be infinite, let us conceive
it to be divided into two parts; each part, therefore, will be either
finite or infinite. If each part be finite, then the infinite is
composed of two finite parts, which is absurd. If each part be infinite,
there is then an infinite twice as great as another infinite, which is
also absurd. Again, if infinite quantity be measured by equal parts of a
foot each, it must contain an infinite number of such parts, and
similarly if it be measured by equal parts of an inch each; and
therefore one infinite number will be twelve times greater than another
infinite number. Lastly, if from one point of any infinite quantity it
be imagined that two lines, AB, AC, which at first are at a certain and
determinate distance from one another, be infinitely extended, it is
plain that the distance between B and C will be continually increased,
and at length from being determinate will be indeterminable. Since
therefore these absurdities follow, as they think, from supposing
quantity to be infinite, they conclude that corporeal substance must be
finite, and consequently cannot pertain to the essence of God. A second
argument is assumed from the absolute perfection of God. For God, they
say, since He is a being absolutely perfect, cannot suffer; but
corporeal substance, since it is divisible, can suffer: it follows,
therefore, that it does not pertain to God's essence.
