I think people make a big deal out of "This is God's beer" that's just not really there. However I like the angelic idea in general. Pair him with Uriel and Harry's got 2 "watchers" on his side. They could be the same I guess, but that'd be a little lame.

Man, I wish Christian tradition still had all this great apocrypha and mythology going on. SO INTERESTING!
