Proposition 1: Strictly speaking, the New Testament says nothing at all about homosexuality.
There is not a single Greek word or phrase in the entire New Testament that should be translated into English as “homosexual” or “homosexuality.” In fact, the very notion of “homosexuality”—like that of “heterosexuality,” “bisexuality,” and even “sexual orientation”—is essentially a modern concept that would simply have been unintelligible to the New Testament writers. The word “homosexuality” came into use only in the latter part of the nineteenth century, and, as New Testament scholar Victor Paul Furnish notes, it and related terms “presume an understanding of human sexuality that was possible only with the advent of modern psychological and sociological analysis.” In other words, “The ancient writers . . . were operating without the vaguest conception of what we have learned to call ‘sexual orientation’.”1 (In the rest of this article I shall use the terms “homosexual” and “homosexuality” strictly for the sake of convenience.)
it's a good read and not terribly long.
