If he hadn't been going out and diddling other men, one could argue that. Once he stuck another man's dick in his mouth or his anus, that argument kind of looses its meaning.
But to be clear this particular priest is a hypocrite. The inference is that all Christian priest/pastors are cannot be made.
man I can't believe I'm about to post this but...
I think Walter's point was that the preacher regardless of being a homosexual himself, truly believes it's a sin and that homosexuals (including himself) will go to hell.
so he hasn't preached anything hypocritical (by the definition of that word) he has preached what he believes to be true.
