No money I have ever given has been used for anything of the kind. I know this for a fact. I attend a Latin Mass parish. We’re not really part of the diocesan structure as other parishes are. And, anyway, we have a very good diocese which has not had the problems other diocese have had at anywhere near the frequency other diocese have had them. My previous diocese also had almost no cases of abuse committed by diocesan priests for the decade I lived in that diocese. Pick a good parish and diocese and you don’t have problems.

Follow the law - as good bishops and priests do.
