All you have to do is read the Bible story of Abraham or Jacob and see the misery that having MULTIPLE WIVES brings into a home, to KNOW that POLYGAMY was never God's plan. It brings no more happiness today than it did back then.
As Christians, if we want God's blessing on our family, we need to follow the PLAN He gave us from Creation ~ ONE MAN & ONE WOMAN
Yes, if your goal is to believe anything you want you do what all people who want to hold fast to their beliefs "as" truth do.
They …
1.) Gather whatever they can “use” to prove what they “want to believe” to be truth.
2.) Accumulate all evidence they believe proves all opposing views incorrect.
3.) Assume their beliefs are unquestionable truth, and interpret everything in such a way as to make it all support, or at least not negate, their beliefs. Think about it. If your beliefs are unquestionable truths, all “valid” data, must support … or at least not negate, your infallible beliefs, right?
4.) Reinterpret, ignore, discredit, invalidate … anything that doesn’t seem to fit with their views, Why? Our beliefs are “Fact” Valid data interpreted correctly can’t contradict the facts.
5.) Gather all the other experiences, feelings, data … to solidify their beliefs such as signs, wonders, spiritual gifts or facts about your belief group. Things like: we have a burning in the bosom, we speak in tongues, we perform signs or wonders, a statue of Mary came to life and told us our belief groups views are correct, we have prayed to God for the truth and received “feelings” or even signs from heaven. Or, on a more concrete level: Our belief group is the oldest, largest, fastest growing, wealthiest, has the most experts with doctorates… Include anything that adds assurance that your views and belief group have the most truth.
But these are the things we do "if" we just want to believe what we want to believe, and have reasons for discarding the rest. This process closes our eyes, ears and hearts to even considering anything else. And this process allows all the people from every belief group that believes themselves Christian to believe the gospel is simple, while each of them believes completely different “simple” gospels. Everyone gets what they want. And every belief group knows they love the truth and have the truth using this Methodology.
So, decide what you want to believe, gather what you can "use" to prove those things true and "use" to prove all opposing beliefs false, and interpret your selected data in the light of the beliefs you so love. But no one gets to truth this way. At best you will harden yourself into what you "want to believe".
Here's the problem. As other people have stated, polygamy was practiced all the way through the bible. Historians of the day said the practice was everywhere. If the Genesis passage, "For this reason..." was a command of God, everyone including God the Father missed it. Jer. 3:6-11, Eze. 23:1-30 ... Note, the modern definition of adultery is not God's. David already had 7 wives BEFORE he committed adultery, and took at least 10 more afterwards. When was Solomon accused of adultery. God says His wives committed adultery against Him. Are you accusing God of not knowing His own will? Are you accusing God of sin?
But what about Jesus command to only have one wife?
The Passage in Question
Mat 19:3 Some Pharisees came to Jesus, testing Him and asking, "Is it lawful for a man to divorce his wife for any reason at all?" 4 And He answered and said, "Have you not read that He who created them from the beginning MADE THEM MALE AND FEMALE, 5 and said, 'FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH'? 6 "So they are no longer two, but one flesh. What therefore God has joined together, let no man separate." 7 They *said to Him, "Why then did Moses command to GIVE HER A CERTIFICATE OF DIVORCE AND SEND her AWAY?" 8 He *said to them, "Because of your hardness of heart Moses permitted you to divorce your wives; but from the beginning it has not been this way. 9 "And I say to you, whoever divorces his wife, except for immorality, and marries another woman commits adultery." 10 The disciples *said to Him, "If the relationship of the man with his wife is like this, it is better not to marry."
Context: The Law the Pharisees are Questioning:
Deu 24:1 "When a man takes a wife and marries her, and it happens that she finds no favor in his eyes because he has found some indecency in her, and he writes her a certificate of divorce and puts it in her hand and sends her out from his house, 2 and she leaves his house and goes and becomes another man's wife, 3 and if the latter husband turns against her and writes her a certificate of divorce and puts it in her hand and sends her out of his house, or if the latter husband dies who took her to be his wife, 4 then her former husband who sent her away is not allowed to take her again to be his wife, since she has been defiled; for that is an abomination before the LORD, and you shall not bring sin on the land which the LORD your God gives you as an inheritance.
For background as to what God really did command regarding marriage, read: Ex. 21:10, Lev. 18:5-23, Lev. 20:10-21, Deu 21:15-17, Deu. 25:5-6, Isa 4:1, Jer. 31:32.
And, from a Jewish perspective you were not officially married until you became one flesh. Then the marriage is "consummated". So Solomon was "married" and had sex with about 1000 women. He did sin, but it wasn't the number, it was that he took foreign wives. The biblical family, including for God the Father, is a husband, all his wives, and all the kids by all those wives. Which explains how popular polygamy was in Jesus day.
So let's look at Jesus reply to the "Can I divorce any of my wives for any reason at all.
4 And He answered and said, "Have you not read that He who created them from the beginning MADE THEM MALE AND FEMALE, 5 and said, 'FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH'? 6 "So they are no longer two, but one flesh. What therefore God has joined together, let no man separate."
If Jesus is saying God only intended monogamy and that is the only valid God approved marriage, what happens? Mass chaos. Well, I am the second born son, but of my father's first wife. His second wife had a son before her. Does this mean that I can kick my elder brother to the curb and claim his inheritance? From the divorce standpoint, if it is only the first wife that is approved by God, do I have to kick all my other wives to the curb? Their kids as well? Are you saying that I cannot divorce my first wife, but I can do so with every other wife? Jesus is descended from Solomon. From David's 8th wife? If that is invalid, what about Jesus kingship?
In a society where polygamy is not unusual, and where everyone including God practices it, if Jesus was making such a claim reversing all the O.T. laws and creating a meaning for that Genesis verse no one before Jesus at this moment is claiming all kinds of questions present themselves and it would have disrupted society of that day from the top to the bottom.
BUT ... if Jesus is saying, if you had sex with them God considers you joined, whether you have one wife or twenty-two wives, then their response to Jesus statement makes sense.
10 The disciples *said to Him, "If the relationship of the man with his wife is like this, it is better not to marry."
If your goal is to believe what you want whether it accuses God of sin, or of not knowing His own will or not, have at it.
1Ti 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils; 2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
Interestingly, almost all of Christianity allows marriage. Even Roman Catholic priests can marry. they must just give up some of their rights to practice some sacraments. These are the end times. What almost all groups within Christianity forbid is polygamy. Just about everyone forbids a man from taking a second wife.
I get it. If your goal is to hold fast to a belief, no amount of biblical truth, context, logic, reason will ever convince you otherwise. As far as trouble with multiple wives. Yes. Even with one you will have trouble. With more than one you will have heaps of trouble.
1Co 7:28 But if you marry, you have not sinned; and if a virgin marries, she has not sinned. Yet such will have trouble in this life, and I am trying to spare you.
