I believe you are being PC again Steve...
Not that I really give a hoot, but the Bible clearly states that marriage is between a man and a woman.
How are two dudes sucking each other's winkies, gonna conceive a child...?
You can't have it both ways.
Agree .. just not in the Adam and Eve story and not until it was written. And many "early" marriages weren't necessarily for children. Family fortune, land, war and even peace were often higher on the priority list.
Not saying the bible doesn't overall focus on marriage between man and women .. was only refuting Canute's premise that the bible was the first to create it.
