I love to hear statements like: "God doesn't support Gay Marriage" or "Gay Marriage is a sin, the Bible says so". But the funny thing is, the Bible says nothing about it... Nothing.
I found this piece in HuffPo, by Lee Jefferson that points out a couple of things the Bible doesn't discuss:
Second, the Bible does not clearly endorse one form of marriage over another. Adam and Eve as the divine groom and bride is one Biblical arrow in the quiver of same-sex union opponents. The Yahwist creation story in Genesis (the second creation story) has God forming Eve out of Adam's rib, and Adam exclaiming their unity ("this is at last bone of my bones and flesh of my flesh"). This is a gender creation story, not a creation of marriage story. Adam and Eve do not exchange rings, say "I do" and have a jazz band reception in Paradise.Unless these folks are ready a new, new version of the Bible, Gay Marriage is nowhere to be found. Please check out the article.
Third, the Biblical arguments against same-sex marriage are not proffered from texts that deal with marriage, but from texts that purportedly deal with same-sex orientation. Same-sex marriage is rejected as un-Christian and immoral on the basis of a myopic reading of a very few Biblical texts. And the texts in question are scant indeed. The most referenced texts are Genesis 19; the holiness codes of Leviticus 17-26, and in the New Testament, Paul's First Letter to the Corinthians 6:9 and his Letter to the Romans 1:26-27. Not only does one have to "hunt" for references to same-sex practices, but there are no gospel texts that treat the matter. There is nothing attributed to Jesus of Nazareth that has anything to do with same-sex orientation. According to the gospels, Jesus never commented on same-sex practices; that fact certainly bears repeating to anyone criticizing the gay community on Christian grounds. Largely, same-sex practice is a topic of little interest to the Biblical authors.
