And the Lord God said, “It is not good that man should be alone; I will make him a helper comparable to him.”And the Lord God caused a deep sleep to fall on Adam, and he slept; and He took one of his ribs, and closed up the flesh in its place. 22 Then the rib which the Lord God had taken from man He made into a woman, and He brought her to the man.And Adam said:



“This is now bone of my bones

And flesh of my flesh;

She shall be called Woman,

Because she was taken out of Man.”



Therefore a man shall leave his father and mother and be joined to his wife, and they shall become one flesh.



Genesis 2:18, 21, 23-24



Jesus said, “Haven’t you read that at the beginning the Creator ‘made them male and female,’ and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’? So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”



Matthew 19:4-6



Marriage was created and defined by God and confirmed by Jesus. End of Argument.
