IIRC, the Vatican Website has an article that explains that homosexuality is NOT a sin. We are exactly as G-d made us and wants us.
According to the article it is homosexual acts that is sinful.
(I assume because a new life cannot be created thru homosexual sex—which is, of course, the ONLY purpose for sex ;) ///
So, where do the so-called Christians get-off judging other people?
