There are a lot of things that would make someone a lousy marriage partner that aren't Biblical grounds for divorce. There a lot of things that would send someone to Hell that are not Biblical grounds for divorce. (There are married pagans, too, after all.) Jesus did not mention witholding sex as a valid reason for divorce. In first-century Judaism, a husband was supposed to have sex with his wife and a wife was supposed to have sex with her husband, though there was probably more emphasis on sex as a wife's right. I encountered an argument someone made online that 'sexual refusal' was grounds for divorce because it is 'sexual immorality' and the NIV translates porneia as 'sexual immorality' where the KJV used 'fornication.' Their argument was based on the wording of the KJV. Porneia means something more like 'whoring around.' Our traditional wedding ceremony is based on a certain version of the Anglican Book of Common Prayer, and some churches use newer versions along the same thing. The Anglican's modified Roman Catholic traditions, of course. I've read and heard that the old Anglican wedding ceremony included these promises,With this ring I thee wed, with my body I thee worship.They basically agreed to have sex with one another. Maybe it would help marriages today if we'd have couples agree to all the Biblical requirements of marriage, including those in I Corinthians 7. Some people seem to think their marriage is based on whatever they promised on their wedding day. I think one of the reasons this is a big issue in marriages is because of what our culture emphasizes about sex. The issue of sex in our culture has been taken over by fornicators and homosexuals. We have fornicators setting the sexual morality standards in college. To hear these pundits talk, the three sexual sins are rape, having sex without a condom, and denying ones true sexual orientation. Rape is a huge problem on our college campuses. One of the reasons it is a huge problem is because of the fornicator culture. It's considered normal for an unmarried couple to have sex. If they meet in a bar for the first time and go off and have 'consensual sex', that's considered their right. So then throw in a lot of alcohol at bars into the situation, or lots of liquor at a fraternit party, and you have situation where drunk young people have sex with each other, and waking up in the morning and trying to figure out if it is a rape. Rape is one-way, with her accusing him, and the police laughing it off if he complains that he was too drunk to make a rational choice. And then there are flat-out cases of rape where he claims it was consensual. But we used to have a society where fornication was considered a crime and sin. If there was no rape, they could face the penalty for fornication. On college campuses, there are those teaching young people that it is wrong to tell a woman not to go out and get drunk wearing a skimpy outfit, or she might get raped, as if that somehow justifies rape. (Telling people to lock their doors must be immoral.) The main emphasis when it comes to sex is consent. Instead of telling young men not to have sex with women they aren't married to, they tell them not to have sex with her against her will. Historically, under common law, it was understood that a husband and wife were supposed to take care of each other sexually. There are vestiges of this still left. One can still sue for lack of consortion if someone is injured in an accident for some reason. The take-away young people come out of college with is that sex is all about being willing, only if I want it. At least that is what the women come out of college being taught on this subject. We've got a very 'my rights' focused culture, rather than 'my responsibilities.' Where are people hearing the idea that if they get married, they have a responsibility to take care of their partner sexually? Some churches teach this occasionally. My guess is others do not mention it at all, either out of a false prudish sense of morality, or some other reason. Certainly, if a couple were both raised in the church or spent significant time there, or went through some marriage counseling, either. I'm sure there are plenty of men addicting to porn who have dutiful, loving wives. It's kind of shocking to hear comedians make allusions to pornography, and the audiences laugh as if they know the details the comedians are talking about. One comedian was talking about Sarah Palin as fitting some kind of school-teacher porn stereotype. The shocking thing is that porn is so widespread that an audience of regular people know 'inside jokes' about it. Some men come into marriage with a background of watching a lot of porn regularly. But I suspect that some men who repented or maybe never had a major problem with it are tempted by porn if their wives shut them off and ignore them. One blogger described this as a man being so thirsty that he'd drink polluted sewage. I hear that some of the men who go to prostitutes are really lonely hurting types. None of this justifies sin, but there are things that weaken people up for sin. A lot of alcoholics and drug addicts turn to substance abuse in reaction to emotional pain.Anyway, I think this topic is something that needs attention in the church. Husbands and wives need to take care of each other (each their own that is) sexually
