I went to Catholic school (in Canada) and was taught (by priests and nuns) that Christianity probably started as a mushroom cult, Jesus probably didn't exist but was a composite of various wandering prophets/lunatics wandering around about that time (apparently it's been a popular way for idle young men to pick up chicks for centuries), etc... The bible was taught as a (very flawed) historical document and not the literal "word of god" as it was decades before. Even services were performed as comforting archaic rituals rather than stodgy religious services. This was consistent across schools, and even the one that was the seat of a cardinal was no different.

The Catholic religion gets a lot of flack (and deservedly so!), but at least they recognize it's basically just ritualistic bullshit (in Canada at least). Looking back, I think they are just happy to have people in their weird shroomless mushroom cult.
