I'm not a liberal by any sense of the word but I have studied the meaning of the scriptures and it might surprise us, what we claim to be "pretty clear" on the subject usually isn't.
To consider the other side's views, let's look a closer at scripture again whether it is really talking about divorce here. Context and history of what Jesus is saying is very important. Many would say that marriage is for life and you can't divorce except in cases of adultery, and if you do remarry you commit adultery. That's one interpretation. But there is another, believe it or not.
When I read the bible on the passages claimed to say divorce, it says putting away. It doesn't say divorce. Why is that? Look up any reputable bible translation like KJV or ASV it doesnt say divorce it says put away.
Jesus said:
Mat 19:9 And I say to you, Whoever shall put away his wife, except for fornication, and shall marry another, commits adultery; and whoever marries her who is put away commits adultery.
Jesus is speaking about "putting away". Do we even know what that means? Maybe putting away is not the same as divorce? Perhaps Jesus was referring to the Pharisees putting away their wives without giving them a divorce notice?
Perhaps Jesus was addressing the way the Jewish men would put away their wives for any reason, even trivial reasons?
The reason it causes her to commit adultery, is because there was no proper divorce certificate. The man would simply "put away" his wife without giving her a proper divorce. This meant she was still legally married to her husband while he married someone else, or she married another.
Does the bible really say God hates divorce? Well no it doesn't really, it says He hates putting away:
Mal 2:16 For the LORD, the God of Israel, saith that he hateth putting away:
What does God hate? God hated the practice of sending away their wives without giving them a certificate of divorce, and then illegally marrying another. This also prevented the wife they separated from, from marrying another. It may have resulted in the wife being without rights in society, having to beg , or go into prostitution.
When God divorced Israel, God cut off the relationship properly. Note as it says below, first he put her away, and then he gave her a bill of divorce. If God hated divorce so much, why did God Himself divorce Israel? We know that God doesn't commit sin, yet it says that God gave her a bill of divorce..so divorce must not be as much of a sin as people claim it to be.
Jer 3:8 And I saw, when for all the causes whereby backsliding Israel committed adultery I had put her away, and given her a bill of divorce; yet her treacherous sister Judah feared not, but went and played the harlot also.
If we take a look at Strong's, the word for divorce here means a cutting of the matrimonial bond. The word for puttng away literally means to send away. What should be obvious is that putting away (sending) is not the same as divorce (cutting). Putting away seems something less than divorce, maybe the start of divorce.
Three things were needed for a proper divorce, writing a bill of divorce, putting it into her hand, and sending her out of the house. Then it says she may be another man's wife.
Deu 24:1 When a man hath taken a wife, and married her, and it come to pass that she find no favor in his eyes, because he hath found some uncleanness in her: then let him write her a bill of divorcement, and give it in her hand, and send her out of his house.
Deu 24:2 And when she is departed out of his house, she may go and be another man's wife.
So those passages which most people say refer to divorce (cutting), do not say divorce, they actually say putting away (sending).
Maybe Jesus's teachings are not about divorce, but about the men putting away their wives without good cause. Regardless of our interpretation, Jesus's teachings here do not address the situation of an abusive husband, whether or not a woman can divorce. It seems to me to be all about men putting away their wives, which makes sense as He is talking to men (his disciples) afterall.
Now to consider why fornication is the one thing that is acceptable with putting away..
Mat 5:32 But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
Firstly, note it says put away his wife, there is no mention of the bill of divorce, which is something else. Why is fornication the thing which is allowed? Because fornication means there was no proper marriage to begin with. In other words, she should simply be put away, and there is no need for a written bill of divorce since there is no legal marriage (since they were engaged in fornication).It could also be noted that this exception of fornication is not mentioned at all in Mark's gospel. If we were to take Mark's gospel at face value and ignore Matthew, Mark gives no grounds for divorce whatsoever, not even fornication.
I believe Christians are far too quick to make rules and regulations from misinterpreted passages. Even pastors don't understand these passages properly. In doing so, the legalism is even stricter than in Judaism i.e. "you can't divorce under any circumstances except adultery and if you do you commit adultery". Yet it says in Deu 24:2 that a divorced woman may marry another. Since when did Christianity replace the Law of Moses with an even stricter one? Aren't the Christians supposed to be living by grace and not under law? Yet in many instances I find the laws which christians live by and what preachers preach , to be far more strict than the Law of Moses. And no one can keep these christian laws on divorce anyway, considering the divorce rate amongst Christians is really no better than the rest of the world.
Think about this issue from the point of view of a God of grace, mercy and love. Why should a woman who through no fault of her own be subjected to abuse by her husband, pay the price for it the rest of her life by never being allowed to divorce or remarry. That doesn't sound fair to me. Instead, she is held at ransom for the rest of her life for the man which abused her. Then for the wife's ( or husbands) sake it is better that the husband (or wife) has an affair than to be abused.
Although marriage for life is God's intention as Jesus said, we don't live in a perfect world and sometimes divorce is the proper thing to be done, just as God divorced Israel after they had backslidden too far. And after divorce there should be no threat of being labelled an adulterer if a divorcee wishes to marry another.
I believe Jesus was making tighter rules however, about the way they went about divorce. I believe Jesus was really addressing the loose standards under Moses's time. He was saying "guys you can't divorce your wife for any reason you like, as you did under Moses". Under Moses the man could divorce his wife if he found something displeasing with her. Now he is telling them, God's intention is to be married for life.
However, I don't think Jesus was saying that properly divorced people if they remarry, commit adultery. He was not saying, that divorce is acceptable only after adultery, but no other situation (violence, abuse etc included). He was not addressing the situation of a woman in an abusive relationship, but was speaking to men (his disciples) about putting away their wives.
