Sci-Fi Spirituality?

Remember a movie called Powder? It's about an albino who could use the totality of his brain. He was more "fully human," if you will. That's what made him a "spiritual" being. Great flick.

Anyway, I had thought of using religious parlance as if some sense of "God-Presence" were common place. (Could it be that the existence of "God" has been "proven"? It is sci-fi after all.) In this setting, dualism is out (which causes its own problems). Since fully human and fully divine are considered to be two sides of the same coin, psychic ability is considered to be a sign of call to priesthood. (It's the whole gifting/calling thing.) This may very well create a caste and have its own dark and violent side (which of course challenges the whole foundation of the religious orders).
