I thought Catholicism was all about guilt, being repentant for your sins, and having your sins forgiven.
Well yes, but that is only the perfect strategy for manipulation of the people.
You are saying that "Deity X" has placed this poor priest on Earth, had him repress a basic desire which was "X" given, and will then punish him for it. Surely the priest knows, or at least hopes, that his sins will be forgiven... repressed urges and all.
The problem with your logic is that "Deity X" placed the priest on his situation; and you don´t take into consideration that it was men´s greed & ego who put that priest there in the first place. A priest and a street bum are not much different in the eyes of the Lord. Besides, the fact that he is a priest, or whatever, does not means his acts will be considered different than anybody else´s.
This should only break down into deviant behaviour where you have a priest that does not truly believe the very faith that he represents. His "energy" in effect should be expressed as, *gulp*, prayer. (I can't believe you just got me to say that, and I wont repeat it.)
I got a theory on which priests are some the least religious people there are, with a few exceptions. Most priests don´t trust what they are saying, because they have never experience God by their own account, they are just saying stuff they learned from other people, not themselves. You will never wholeheartedly trust something you were told by others if you haven´t experienced it yourself.
