I am guessing that we are talking about the catholic church, and I could be wrong because I dont know about their rules, but I dont believe they would have rule not severely punishing or sending to police pedos. I would guess they catagorized it as someone who broke a rule, not committed a crime.
That is a long wiki page, you will need to point to the part you are referring to.
If you want to point to institutions with pedo problem, then you should look at government schools which have much more than churches. But I think this is more about ragging on religious institutions than actually understanding what is happening.
