LH - I agree with your distinction between Talmudic law and Christian law.

It seems, though, that many Christians do refer to 'Old Testament' quotes to justify quashing the rights of homosexuals and other groups.

I am no scholar, but I don't recall Christ being quoted as saying there was anything wrong with sex. As for adultery, he did use that 'sinless can cast the first stone'.

However, I think the NT came out against divorce, so folks may want to revert to Moses on that one.
