Considering marriage and the Bible.

I say over and over again in this blog that people of faith pick and choose what they want to believe about their religion. As many people as there are believers in a religion, that's how many different versions of that religion that exist.Although the conservatives talk about traditional marriage, I've yet to see the actual Bible quote that says marriage is one man and one woman. Did I miss that reference somewhere? I might have - I'm not a Biblical scholar.
