” But on the other hand he seems to overlook the many examples of polygamy in the O.T. and if it was indeed a common practice in N.T times there is very little explicit condemnation of it and no details I can recall of how to deal with the problem in the way you suggest.

Craig, God allowed a lot of things because of sin. What was happening to widows in the OC? Or women who had been raped? Even married woman were nothing if they could not supply a male son. That is sin. It was the sin of patriarchy.

Because of the sin of Patriarchy women had to have protection of a male for basic food and shelter. Polygamy plays into all of this.

God does not “overlook” polygamy. He allowed it because of sin.
Have you ever wondered why God implemented the Law in the first place?

I think we make the mistake of reading the OT and thinking God approved of things He did not. He was working through sinful people for His purposes. Do you think God approved of Abraham having sex with his wife’s servant in order to have a son? Yet Abraham was praised for believing God. How can this be?

Do you think God approved of Solomon’s 600 wives? Or David’s sex with Bathsheba? Or his planned murder of her husband to get him out of the way? David lost their son over it.

Where do you find slavery condemned in the NT? Yet, we cannot imagine owning another human today even though, just 150 years ago, many professing Christians owned other humans and claimed it was Biblical? What changed?

Before the fall, God commanded One Flesh Union. He did not change His mind on that.
