This may be the weirdest question ever asked here, but it's actually quite a serious one - by which, of course, I mean that It's not an idle speculation. I've had an idea for a novel and I wondered if it was in keeping with Catholic doctrine. The idea is that the ancient Celtic gods really did exist, and continue to exist to this day, but now live amongst the general population, suitably disguised. So far, so Buffy the Vampire Slayer.
My twist is this: the likes of Richard Dawkins has said, in that rather undergraduate, "aha, gotcha!" way that the New Atheists specialize in that he doesn't believe in one more god than Christians don't believe in. He argues that if we find Thor and Odin impossible to believe in, then why do we continue to believe in a Supreme Creator? The standard answer is that Thor and Odin, if they were to exist, would be merely created beings, like any other, existing in time and space, just as we do. Essentially they would be just tremendously powerful living beings, but not "God". Now, suppose such a being really did exist, and accepted the existence of the Supreme Creator, and that he himself was merely a very powerful being. Assuming that he or she had no more communication with God than you or I, that they had no more certain knowledge of the existence of God that you or I have, could such a being partake of the sacraments of the Catholic Church? Could he be baptized? Could he receive Communion? Is there anything in scripture or the cathecism or moral theology which would prevent him using his powers in the service of the Church or the general good?
As I say, weird question, but I'm a weird guy.
