I think if you are looking for moral authority you should pick and institution whose leaders don't diddle children.
Gee, I never would have expected that response.
This is the fallacy of guilt by association. The priest himself is not accused of child abuse. In this case, his competence to judge what forms of "entertainment" represent entranceways to the occult follows from his performance of 20-25 exorcisms per year, in which case, his judgement carries more authority than yours.
Regardless, despite the media hype, the percentage of "diddlers" in the Catholic Church is comparable to that in other Christian denominations (and probably to teaching, although I don't know of any reliable numbers). Not that the problem isn't horrible, but these facts help to put the problem into perspective.
Furthermore, sexual abuse within families is far more common than sexual abuse by clergy, yet no one advocates the dissolution of families for this reason.
The real problem is two-fold, the transferral of priests accused of child abuse by bishops and the admittance of homosexuals into the priesthood. Both are the result of poor decisions by individual bishops. The Catholic Church does not hold that bishops are infallible or impeccable. Judas was a bishop, chosen by Jesus Himself.
