I'll give you this.. since you just want the words of Jesus
"And He answered and said, “Have you not read that He who created them from the beginning MADE THEM MALE AND FEMALE, and said, ‘FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH’?-- Matt. 19:4-5
From the beginning, this is how God seen marriage, husband and wife, having and raising children.
Believe it or not, accept it or reject it. Everybody gets to choose.
But, just because you have a choice doesn't mean you can't make the one thats wrong. For me, anything that doesn't look like this passage would be wrong.
