Where in Genesis 29:29-33 do you discern God’s support of polygyny? In fact, when The Lord saw that Jacob had taken Rachel as a second wife, and loved her but despised Leah, he punished both both Jacob and Rachel by making Rachel barren while Leah bore multiple sons.
Your interpretation is not objective and I’ll explain why. Genesis 29:29-33 shows God’s support for polygamy because God shows concern for that TWO women are not loved equally by the same man (Genesis 29:30-31). If God was against polygamy, He would not be concerned with that aspect but rather with why Rachel is committing adultery with a married man or why is Jacob lusting after a SECOND woman. IF the all-good and perfect God were to ACT Himself in such a situation He would’ve either broken up the polygamous marriage or ordered that the second so called wife be punished. Yet, God ACTS by helping these TWO women, Rachel and Leah, to be loved by ONE husband (Genesis 29:31-33 and Genesis 30:22-24).
In fact, I can’t think of a single polygamous relationship in the Bible that is presented in a positive light. In each, the writers highlight the troubles that these people faced as a direct result of their multiple marriages.
The problem was not polygamy but rather the problem was the form of patriarchy (women suppression, the man RULES the wife, arranged or NON-consensual marriages) that existed in that culture, much like the Middle East today. Under those conditions, BOTH monogamy and polygamy would be practiced in oppressive ways and that’s even if the Biblical writers were “silent” on the feelings and personal behavior of many of the women in monogamy. This oppression has existed cross-culturally and beyond the OT times as well so it’s not just an Old Testament problem.
This is not support of polygamy; it is, at best, a tacit acknowledgement that it happened without having blatant condemnation. But silence is not support. Regulating something is not support (I’d point out that in Exodus, God regulates slavery - and no one is suggesting slavery is moral; we also know God regulated divorce, even though it is clear that He hated it).
In Genesis passages I referred to earlier in this post we see that God was not silent on polygamy. God’s ACTIONS in that case speak louder than any words that you can come up with. A Holy/perfect God treatment of other UNREPENTANT adulterers (polygamists, by your logic) speaks volumes.
Also, slavery is not always a sin and I have Catholic sources I can present here as support. Also, the Bible does not say nor indicate that God hated polygamy. You don’t bless and make nations and have your only holy/begotten son (Jesus) come out of a line of UNREPENTANT polygamists.
God created Adam and gave him ONE wife - Eve. He did not offer him multiple wives. When God commanded Noah to build the ark, he was told to take his own wife, his three sons, and their wives - if polygamy was so common and supported by God, why wouldn’t he choose someone with a polygamous relationship with whom to establish His covenant? He was literally starting over at that point - with four men, each of whom had ONE wife.
It isn’t necessary that the first marriage be polygamy since polygamy was optional. And by your logic, had polygamy been the first or original marriage, all marriages would’ve had to been polygamous.
Here’s my last - Jesus said to his followers that they should go forward and teach everything that He had shared with them. He did not say, “Here is this book - go forward and teach only what is contained in it.” We know that polygamy is not accepted by the time of the New Testament, and that the teachings of those who followed Jesus are not consistent with a polygynous or polygamous society (as a basic point, whenever a husband’s obligation to his wife is mentioned, wife is used as a definite singular noun, not an indefinite noun or a plural noun).
Why? Because that was God’s will and what Jesus commanded to be taught.
First off, the NT does not contain all of the rules on marriage and sexuality so whatever it left out or whatever it’s silent on can be picked up from the OT. My next point will be in two parts. Giving instruction for a two person marriage does logically mean that the authors were AGAINST polygamy. It could be that they were only dealing with monogamy.or just a two person marriage in general and could’ve made rules later on or left it up to people to read the OT. The second part of that point is that some of those same obligations mentioned for the husband towards one wife can also be done towards two wives, as well so there was no need to mention “wife” or “marriage” in any plural form.
It really shouldn’t take going through all of this to show that polygamy is moral. Just the one example I gave you about Jacob and his wives proves my case. Anything beyond that you would have to show that my point on Jacob is wrong or at best you’re setting this up to turn into a contradiction (if we can’t
logically refute each others points).
