Theology is "theo-logos" or god logic. A god is a high level force or principle that guides or controls a lower one. So theology is the logic of high level control.

But abstractions are hard for human brains.

So most people's brains hear "the god of something" as a person. But for theologians, a god is always abstract. (Though a god's characteristics may be seen in humans).

The highest controlling force, the ultimate god above all gods, must be logic itself. Because if logic says a thing, then it is so. That is, logic rules everything else.

If a god cannot be proven by logic then it is not supported by the highest god. It therefore risks being destroyed by the superior god.
