I think the problem lies with the Catholic law or rule that says priests have to remain celibate. Which is not biblical. God never intended for them to be celibate. You would think the catholic leaders would know that rules like that do little to change the heart. When they give into sexual temptation, it often leads to unnatural sexual acts like homosexuality and pedophilia.
Absolutely there are other sexual predators in other denominations, but it is a fact that a higher percentage of them are in the catholic church. What is the reason for that? Probably the celibacy rule, and the fact that the Pope and other catholic leaders try to hide it from the public eye. Trying to hide this, or deny it, is as bad as the act itself, because it just leads to more of it.
