Incidentally, I think that Donatism is loosely related to Luther's apostacy in that it encourages clubby churches of the "saved" htat are at the same time frightened of the sacraments. But I don't see a straight link to the pederast priests scandal.
Yes, that makes a lot of sense. As for any connection to the pederast priest scandal, you're right it has no direct link. It's more of a personal thing. It's easy to become discouraged by this filth that seems to have infested even some of the highest levels of our Church leadership. People claim to have "lost their faith" over this. But how can one lose faith in the Sacraments?
