Paul begins a long discussion of marriage and divorce with what appears to be a quotation: “It is good for a man not to touch a woman” (7:1-2). Who said this? Paul, or the Corinthians? In modern commentaries, this is the Corinthian attitude about marriage and sexual relationships, possibly another slogan from a faction in the church. Alternatively, some translations and commentators take this as Paul’s statement from an earlier letter or teaching at Corinth. Like 5:9-11, this statement was misunderstood and now needs to be clarified.
In contrast to Roman sexual ethics, someone in the Corinthian church claimed it was better for believers to be celibate. If they are married to an unbelieving spouse, they must divorce the unbeliever and if they are unmarried, they should never marry.
To “touch a woman” is a euphemism for sexual relations, not marriage. The NIV (1984) originally translated the word as marriage; the NIV (2011) and the ESV both have “sexual relations; the NRSV has the literal phrase, “touch a woman.” This phrase refers to sex as recreation as opposed to procreation. There are at least twenty-five examples from Greek and Roman sources (Ciampa and Rosner, 1 Corinthians, 273-4; Gordon Fee, “1 Corinthians 7:1 in the NIV,” JETS 23 (1980): 307-24). Ciampa and Rosner suggest “it is not good for a man to bed/bang/shag a woman” (1 Corinthians, 275). Perhaps to update this a bit more: “it is not good for a person to hook up” or “it is not good to have friends with benefits.”
In the Roman world, sexual relations in marriage were intended for procreation, having legitimate heirs. A man was expected by society to meet his physical needs by extramarital affairs, prostitution, or his slaves. Sex with a married woman was forbidden (adultery was outlawed by Augustus, but men could have sex with unmarried women (and slaves). Kyle Harper suggests “Slaves played something like the part that masturbation has played in most cultures” (From Shame to Sin, 27). Prostitution was legal and common, as was homosexual sex (although it was not necessarily a romantic relationship). Sexual desires were like any other physical desire. Sometimes you need to burp to feel better.
If the Christian was to refrain from extramarital relationships (which were not considered out of bounds by the culture), and the marriage relationship was the only proper place for sexual relations, then Gentile converts to Christianity may have been surprised by recreational sex in the marriage relationship. Does Paul really mean men ought to satisfy their sexual desires with their wife (as opposed to with a prostitute or slave)?
Why would some Corinthian Christians consider abstinence as a good thing? It is possible Paul’s earlier command not to associate with sexually immoral people was misunderstood. If a person was married to a spouse who had been a “sexually immoral” person, perhaps spouses thought they should give up relations with them or even divorce them. That some Corinthian believers were practicing celibacy even in marriage may explain why some men were visiting prostitutes (6:12-17). Men may have thought using prostitution was an appropriate outlet that did not count as “touching a woman.”
Paul therefore challenges the prevailing Greco-Roman culture with his views on sex within marriage as well as outside marriage. Although modern readers are more familiar with Paul’s restriction of sexual relations to marriage, this would have shocked the original readers.

This is extremely interesting. I assume this is another application of a Jewish ethic to Gentiles who come to worship the Jewish God and Messiah. Is that accurate?
Yes, one of many problems which arose when Gentiles began to follow Jesus (meat sacrificed to idols is another major problem in 1 Corinthians 8). In fact, I think most, if not all, the problems in 1 Corinthians are the result of Gentiles not fully applying the Gospel to aspects of their lives, they are trying to do Christianity like a Roman.
Assume, as I think most scholars do, these were primarily “God fearers,” Gentiles who worshipped the Jewish god, engaged in some aspects of Jewish religious and cultural life, but were not ready to forsake their gods and peoples to join the Jewish people. Along comes Paul with a new message about how this works: Gentiles can worship the Jewish God through his Messiah as Gentiles; i.e, without fully adopting Torah and joining the Jewish nation. Yet to do so, these Gentiles must now accept some key Jewish practices. Chief among them is rejecting other gods as worthy of worship. But also a radically different sexual ethic. These God fearers had worshipped the Jewish God just fine while maintaining a “normal” sex life. Now Paul tells them the inclusion of the Messiah requires a complete upending of that life. They’re still Gentiles. But in key ways, they must live as Jews. I think the confusion would be understandable. I think a case could be made it still is. At least in the West, most Christians (and Jews) appear comfortable with a version of a”Gentile” sexual ethic.
I always thought this portion of Corinthians was common sense when I was kid. In American Christian culture these things were just kinda normal. As I have gotten older the more I understand why this teaching is so important. While American Christian culture holds this as the standard, this standard gets broken all the time. Affairs, divorce and other things happen more often than you realize. That’s not even mentioning other cultures where you might find it more the Graeco-Roman culture of Corinth. This phrase of do “it is good for a man not to have sexual relations with a woman” is fairly clear in my opinion. He in the next verse starts talking about how a man should have his own wife and a wife should have her own husband. There is an idea of ownership that I see. Paul says not to deny the spouse their conjugal rights. It seems to me that married couples should be exercising their right to biblical sex. So the phrase we see in verse one would apply to sex outside of marriage, ie: affairs, unwed sex, prostitutes. I think some might think abstinence is a good thing possibly because that is what the jewish religious leaders would do. So this culture might spill its way into Christianity. Also it could be that they thought if it was wrong to have relations with a prostitute that it might well be wrong entirely to have sex. We are not entirely sure if Paul had written any earlier letters to Corinth so it is possible that this was an issue that was addressed and taken to the extreme, and Paul is is simply clearing the air.
