I can understand why some people might not want plural marriage to exist. I can understand why it might upset some people. I accept that. But to then deny the very plain teaching of the Bible and still claim to be a Bible-believing Christian is most definitely not acceptable. Someone who denies the plain sense of the Word of Elohim (God) is living in a delusion. To try and change the sense of scripture to mean something other than what it says is called twisting the Scriptures. And the biggest irony of all is that the monogamy-only people accuse those of us who have more than one wife of doing this very thing! This is a most serious sin and is called "bearing false witness" - it is a violation of the 9th Commandment (Exodus 20:16). To lie in this fashion by denying the Word of God is as serious sin on its own but then to persecute those with multiple wives is, I would suggest, to put the salvation of souls on the chopping block.
I am sometimes asked if I think plural marriage is a salvation issue. At first I hesitated, not wanting to be understood to mean that if you don't practice it you won't be saved, because that is not true. Marriage is not a salvation issue. But in an indirect way there is no doubt that it can be. And I would cite two instances at least.
First, if a woman is forced to marry an unbeliever because there aren't enough godly men to go around in a monogamy-only culture she is opening herself up to spiritual destruction. Marriage to an unbeliever is forbidden:
"Do not be unequally yoked together with unbelievers. For what fellowship has righteousness with lawlessness? And what communion has light with darkness? And what accord has Christ with Belial? Or what part has a believer with an unbeliever? And what agreement has the temple of Eloah (God) with idols? For you are the temple of the living Eloah (God)" (2 Cor.6:13-16, NKJV).
That leaves her with the option of remaining an old maid - a spinster which is hardly attractive. And if she cannot control her natural sexual urge for intimate union with a husband, what will she do? Marry the next best thing to a believer. Paul recognised this problem when he advised:
"... if they [single people] cannot exercise self-control, let them marry. For it is better to marry than to burn with passion" (1 Cor.7:9, NKJV).
It is a fact that more women are coming to Christ than men. It has always been that way (where conversion has been non-compulsive). Logically, polygamy is the only solution. To deny a woman a multiple marriage is therefore to risk her salvation.
In the second place, those who preach monogamy-only may actually be damning souls to hell because they are denying believing women a legitimate place in a plural marriage. And what, do you imagine, Yahweh will say to them on Judgement Day?
"Then He said to the disciples, "It is impossible that no offences should come, but woe to him through whom they do come! It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, than that he should offend one of these little ones" (Luke 17:1-2, NKJV).
The monogamy-only doctrine is an offence to Yahweh because it damns souls to hell. Such a person refusing plural marriage because of false doctrine will probably wish he had never be born when he faces the truth in heaven if he then learns that his doctrine has destroyed souls for eternity. Be warned.
