Jany, you left out the worst bit which is the sentence which follows your quote:
How are we to explain the fact that people who regularly received the Lord’s body and confessed their sins in the sacrament of Penance have offended in this way? It remains a mystery.
A mystery?? It might hard to explain why they did what they did the first time, but there's no mystery as to why the re-offended in such extraordinarly high numbers. It's because the church actively covered up their evil deeds, moved them on to other parishes to hide the problem knowing full well that the chances of them doing it again to other kids was high. We evn have evidence that they had the names and addresses of children being raped by Brendan Snyth and they did nothing. The blame for the vast majority of cases lays squarely at the feet of the institution who's actions led directly to other children being raped and abused.
It's disgusting. The man stinks.
