I don't know, I don't ever recall hearing about pedophilia being as widespread of a problem in religions that do not require their holy men to be celibate as it is in Catholicism. How many Rabbi pedophiles have you ever heard of? Or Greek Orthodox priests? Or Protestant pastors/reverends?
Speaking from Israel, I've heard of far too many Rabbi pedophiles, though they go mainly for the girls, if it makes any differance. I think we have to look at it not from the celibacy angle(The ultra-Orthodox Jews out here are real egg hatchers) but from the authority angle. A priest who commits these acts does them mainly to alter boys, or other youths inside the Church, correct? These guys are raised in awe of priests. Likely a lot of them want to
become priests. The stigma against opposing priests is likely extremely strong(as a parallel, most of the cases with Rabbis involved girls inside the community), and the boys just shut up, until it explodes out.
Which makes the issue ten times harder for the Church. If the issue is just the priests, they'll clean em' out. But if they have to tell their own members not to trust a "holy man"? To suspect him, to not be in awe of him? That could wreck the Church structure.
Not that I'd weep if the Church, or any religous institution, fell. But I'm pointing out the unlikelyhood of getting the Church to clean house and investigate properly.
