Do you know what reason the Bible gives for homosexuality being a sin? I'm asking because I honestly don't know. Is there a reason given? Or does it just say two men sleeping together is an "abomination"?
I know you asked Gadfly but I do happen to have an answer for this question which I found in a book entitled "what the bible really says about homosexuality." In the book it states that the reason homosexuality was considered an abomination was because homosexuality was often practiced by the gentiles in their rituals and daily lives and the Jews were not to do anything that the gentiles did. Or at least it was something along those lines. I'd have to look it over to get the details but I'd have to see if I can find the book at a library or something.
