Piggy,
I notice that you continue to frame all usage of the word "God," as Theist.
And when it's not Theist, it's dismissed as "Humpty-Dumptyism," ie meaningless.
A non-theistic definition of God is like a non-mammalian definition of man.
For example, your reply to the concept that God is the Universe or the transcendent totality of reality, is that this is empty because it defines God as what God isn't. In your definition God can't be the Universe, because God is outside/apart from the Universe. This is an assumption of Theism.
That's not actually my objection.
If you say that "God is the universe", what have you said?
Either you're saying that God is God, and God is also the universe, or you're saying that "God" is simply a synonym for "universe".
If it's the latter, then God has no qualities in and of itself.
The universe is the universe, and we know it exists, and we can consider the universe as the universe, with all the qualities we can verify, without ever touching on the topic of God.
So if you say that "God is the universe" but has no independent qualities, then this becomes one of those cases in which God is merely equivalent to something which, considered on its own, is not God.
So it is one of those cases in which we're asked to believe that God may exist under conditions in which God and not-God are indistinguishable.
And it is unreasonable to demand that anyone accept such conditions. Under those conditions, "God exists" becomes a totally meaningless statement.
But that doesn't have to be the case. For instance, I can say that George is my father, and George is my mother's husband. If they divorce and my mother remarries, George is still my father, but he is not my mother's husband.
George is my father because I have half his DNA. He's my mother's husband because my mother is married to him.
So "God is the universe" could be a statement like "My father is my mother's husband". If that is the case, then we need to know what qualities God has other than being the universe. Otherwise, God remains undefined, and claims about undefined entities are meaningless.
Bur you make a very shallow dismissal of Non-Theistic God language.
You've done little to address God as
The Rational Logos (Augustine, Spinoza, Einstein)
The Ground of Being (Eckhart, Tillich)
The Eternal You (Buber)
and other Non-Theistic views.
It's not that I'm a propnent of these, but I do respect them for their reach toward transcendence and a reality at large that we must relate to as personal beings, but do not have the language or the equipment in our skulls to comprehend.
Care to describe what these are and see if they're not empty, nonsensical, or contrary to fact?
