Since God does not have a body (like us), he “is not composed of extended parts,” as if he were composed of “form and matter.” It’s not as if God were something different from “his own nature.” Nor is it the case that his nature is one thing and his existence another thing. We shouldn’t suppose, either, that God is some type of substance, one that has accidents, traits that can be disposed of or cease to exist. “God is in no way composite. Rather, he is entirely simple.”
