Yeah, "I AM THAT I AM."
I get hiding wisdom from the wise but I don't think God is into obfuscation for its own sake, do you?
Using words can be a form of obfuscation. I see people are bandying the word "cult" around in this thread. People have a tendency to want to label and categorize things. Words can be helpful, generally speaking, but they are inexact and approximate. If I say "chair" to you, you have no idea what color it is, how big it is, what it's made of, what shape it is. If you visited me and I pointed to a chair and said, "You can sit in that chair if you like," your mind takes the word "chair" and you direct your attention in the direction I pointed. When you see the chair for yourself, you know exactly what I meant. Your mind can fill in many details once you perceive the reality of the chair for yourself. If you can't see it, no amount of speculation, no amount of extra words, will produce the precise picture of actually seeing it for yourself. The best you can do is to invent a mental picture in your mind of what I meant by "chair."
Chairs exist with conditions applying. For something to be a chair, it has to meet certain conditions in reality. If an object meets those conditions, we say, "Yes, I'd call that a chair." If it doesn't meet those conditions, we say, "I don't think that is a chair."
God exists unconditionally. Nothing caused Him to exist, He would exist if nothing else existed. Where no conditions exist, words are inadequate since our human wants always want to categorize, classify and put in boxes. God Is. The "absolute truth" does not have any noun following that, no description, nothing. The second you add a noun or description, you've introduced an error of some sort, perhaps small, perhaps huge.
Now while God exists without conditions, I believe He can act interact with creation within time and space. Such actions do not define God however.
I even object to the Catholic idea (carried on by many Protestants) that God has a "'substance." The idea makes me laugh in fact. Substance implies for me something tangible, something I can pin down or weigh, analyze scientifically. The idea that God is a person or three persons leaves me gasping; and the history of how that came about may be worth examining.
At first, the decree of one of the Ecumenical Councils was that God had three personae. That I can agree with since persona in Greek means a mask or a role in a drama. Not three persons, but three masks or personae. God relates to us three ways wearing three different masks. The Catholic theologians weren't always the best with Greek and made that into three persons. God may take on the role a person, appearing to humans as a person -- or as three persons as He did with Abraham -- but such appearances should not lead us into believing what we see is actually God Himself. Hagar thought that! An angel appeared to her, and she said she had seen God. Yet it is true in another way that if you see an angel you have "seen" God -- since Hebrew is like English in that "see" can mean both "view with the eyes" or "perceive the reality of."
Angels are manifestations of God. So while you're not seeing God in His totality, you saw a minute fraction of something which convinced you that God is real, He truly exists. I have "seen" God in some of my fellow human beings. That does not make them "God" however. I am reluctatnt ot discuss visions, but I once saw Jesus in Glory so bright I could not bear to look. I still would not say Jesus is God. I saw God in him however; and that is all the God I expect to see.
The various manifestations of God within time and space do not define God for me. God exists independently of both time and space. Time and space are part of the creation. God is eternal, not subject to time and space. So a particular manifestation of God might cease to exist within time and space, but that could not mean God died. Indeed, the problem with mankind is that the Divine Fire went out. It is said God is a fire and also that angels are fire. Man was also meant to have fire -- but the Sacred Flames went out. Thus the Holy Spirit as a fire needed to be rekindled. Every man, woman and child could become part of how God manifests in the universe. God can fill them all. It would be a mistake however to say that someone is God Himself because he has the Holy Spirit.
