I haven't read much of this thread and no way am I going to either, "let the dead bury the dead" to steal a phrase from the human member of the trinity. And besides I'm lazy.:)
Anyway when we use the word "God" it carries so many different ideas,,, some based on some prejudice of cultural and religious background.
I think belief in a Deity can be good if the deity is a balanced one,,and not restricted by religious dogma,, I mean it can act as a healer of the psyche,,even with religious dogma it can act this way,, but better I think with freedom to break away from dogma or not dogma restricted.
Gods and goddesses are deeply embedded archetypes in the collective human unconscious,,they form a basis of how we view the world due to our evolved instincts,, and were present even before we gained consciousness,, ego consciousness,, is a late arrival on the scene of human evolution,,before that was unconscious instinct (expressed so well in the mythology of Adam and Eve eating the fruit of knowledge of good and bad(thus having there eyes opened to see good and bad) Myths are a projection of the inner workings of the collective human unconscious. We need to look at them metaphorically not literally to get the real meanings.
