Chapter 16 — That it is impossible for God to be a body

It is evident, further, that God himself cannot be a body. For in every body some composition is found, since every body has parts. Hence that which is absolutely simple cannot be a body.

Moreover, we find that a body only moves something else by being moved itself, as is clear to one who considers all the cases. So if the first mover is absolutely immovable, he cannot be a body.
