You can make perfectly reasonable arguments either way on this. One can also make particularly dumb ones:
The Vatican predictably dismissed the programme as “more smoke than fire”, but it would do well to study it. For it makes clear that the celibacy that the Catholic Church continues routinely to demand of all who want to become priests is a strain even for the best of them. There is no suggestion that John Paul II broke his vow of celibacy with the married Mrs Tymieniecka, but his yearning for intimacy with her is plain.
That an ordained priest does not fuck another man’s legal wife is pretty much nothing at all to do with priestly celibacy, is it?
The rules about adultery might have the teensiest to do with it maybe?
