Elder-Basilisk said:Good alternatives, but how about:
Alternative 3: the magics of the clerics represent divine gifts to them intended to enable them to more fully embody the God's will on earth by performing acts beyond ordinary mortal ken. However, these gifts, once given are irrevocable and if a gifted one falls from the true path, s/he retains at least a portion of the gift to use or abuse.
Ah, a more "Roman Catholic"-ish interpretation of what it means to be a priest. (Under RC ecclesiology, it is not possible for a priest to ever cease being a priest, no matter what--that priest's "powers" are fully intact forever. Even a defrocked priest is still "functional", albeit forbidden to exercise those functions. Yes, it does lead to strange and contradictory results.)
