Here's an observation and I invite responses. Patriarchy cannot flourish without the acceptance of the legitimacy of polygyny. Polygyny need not be practiced for a man to be a patriarch, but the possibility of plural marriage must be allowed for a man to truly be a patriarch. If a man's wife has the authority to forbid him marrying an additional wife, then he is not yet a functioning patriarch. A godly husband will take his wife's advice, desires and feelings into consideration, but he must answer to God's authority only.
Biblical polygyny cannot function correctly without patriarchy. Polygyny, as it is portrayed in the Bible is so much more than physical desire or even love. It may involve both of these but also includes at a higher level of importance, honor, responsibility, compassion and godliness. The character of a man is extremely important in both polygyny and patriarchy. In my opinion, our nations emphasis on birth control is un-Biblical. Large families are in keeping with God's program. Also, I believe, no woman should have to raise children by herself. No man or woman should have to live out their lives alone unless they so choose. Biblical polygyny is the answer to these situations. I am not promoting civil disobedience, but simply telling what the Bible says. Try as I might, I can find no other workable solution to these problems of loss of progeny, single parents and loneliness for Christian people than Biblical polygyny. The only alternative is being unequally yoked together with unbelievers, which is unacceptable to godliness.
