I think the term god is meant to represent Thomas Aquinas' interpetation of it:
- God is simple, without composition of parts, such as body and soul, or matter and form.
- God is perfect, lacking nothing. That is, God is distinguished from other beings on account of God's complete actuality.
- God is infinite. That is, God is not finite in the ways that created beings are physically, intellectually, and emotionally limited. This infinity is to be distinguished from infinity of size and infinity of number.
- God is immutable, incapable of change on the levels of God's essence and character.
- God is one, without diversification within God's self. The unity of God is such that God's essence is the same as God's existence. In Aquinas's words, "in itself the proposition 'God exists' is necessarily true, for in it subject and predicate are the same."
As anything that is beyond comprehension, is god. Too many people confuse this concept with dogma and equate the term god with a figurative man.
To that extent, believing in god is being in anything.
I don't know what I think of it honestly. I won't deny the possibility of a god, especially not one simply consisting of everything in existence past comprehension, but I won't embrace one either; especially not a dogmatic god.
