I know nothing about Scientology...
...except that it makes one jump up and down on a couch while on national tv. (Cruise is a Scientologist, isn't he?) My experience with religion doesn't go beyond a secular study of the Abrahamic "big three," so perhaps I should go back to school and take that elective myself.
My feeling is that Christianity should be approached, as I suggested, as one of many...educators would be far more adept than I at determining how best to divide the curriculum among the contenders. I'd be happy to leave it in their capable if tragically underpaid hands.
