A relevant post from Triablogue on the subject.
I should mention: I’m highly sympathetic to the argument there, and in fact, given his argument from Proverbs 5, I think I might have spoken too lightly in my comments in Dan’s post. I think it’s definitely an open possibility that even the OT prohibited engaging in polygamy. In which case, I would have to say, if polygamy is permissible at all, it is only permissible in the sense I raised in my comment to Dan in his previous post: it is permissible to remain in it if you have already been polygamously married.
