It's pretty common to hear that the bible condemn homosexuality, I've seen many references to versus. However, there is a good amount of debate as to which verses are actually speaking specifically about homosexuality.
My question then, are there passages in the bible that explicitly, and without ambiguity or extrapolation, state that homosexual relationships are sinful.
I'm looking passage(s) which either directly quote god/Jesus or are statements from someone who is speaking for God as a proxy, in other words the statement is one that can reasonable be believed to be supported by God, not just personal opinion of the speaker. The passage must reference actual sexual relationship between same sex individuals, and must state that god considers it a sin or something worthy of punishment.
Ambiguity due to translation from Hebrew to English seem to be common throughout the bible. I don't expect an answer to prove that the English statement is an accurate translation, since that requires too much research for skeptics and besides which would effectively be asking to prove a negative. However, ideally an answerer will at least attempt to check for any known debates over potential mistranslations for a particular verse before using it as evidence.
I'm pretty sure I know the the answer, but I've not seen a source without an obvious bias tackle the question, so lets see if this turns out to be more complicated then I expect.
While not required at all for the answer, since it's possible to refute the allegation without it, I would appreciate it if an answerer would at least mention rather a given passage is from old or new testament; owing to the fact that some Christians place different weight on the New vs Old Testament. I'm interested in rather passages exist in both testaments.
