What Paul means
The point of the verse is not hard to see once you read it in context. Paul says this case is so shameful that it would be recognized as disgraceful even outside the church. He is not trying to satisfy curiosity about the family tree. He is confronting a church that had become too comfortable with open sin.
That is why the wording matters. “His father’s wife” is ordinary family language, but it points to a relationship that crossed a boundary. In biblical reading, the most common background is Leviticus 18:8 and 20:11, where relations with a father’s wife are forbidden. That connection helps explain why Paul reacts so strongly.
Why the verse is hard
The verse is brief, and Paul leaves out the details readers usually want. He does not say whether the father was alive or dead. He does not explain whether the woman was a current spouse, a former spouse, or a stepmother by remarriage. He also does not describe the legal arrangement in full.
But the missing details are not the main issue. Paul’s concern is the sin itself and the church’s response. In 1 Corinthians 5:2, he rebukes the Corinthians for being proud instead of grieved. That means the passage is about more than one relationship. It is also about a congregation that had stopped treating holiness seriously.
The most likely meaning of ‘his father’s wife’
Most interpreters read the phrase as a stepmother or a father’s spouse. That is the clearest reading because it fits the wording and the Old Testament background. It also explains why Paul treats the case as a public scandal rather than a private misunderstanding.
A few readers think the father may have died and the man then entered a relationship with the widow. Even then, the family connection would still make the relationship morally offensive in Paul’s argument. So the exact scenario can be debated, but the basic judgment does not change: Paul sees a forbidden and disgraceful union.
How to read the chapter as a whole
1 Corinthians 5 is not just a verse about one man. It is a chapter about how a church should respond when serious sin is being tolerated openly.
Paul’s logic moves like this:
- the sin is real and serious
- the church knows about it
- the church has become proud instead of sorrowful
- the proper response is discipline, not denial
That is why the chapter keeps moving beyond the isolated act. Paul wants the Corinthians to see that their problem is spiritual pride. They have mistaken tolerance for maturity.
For sermon prep or Bible study, that is the safest way to frame the passage. The headline is not family gossip. The headline is a church that would not grieve what God calls wrong.
Main ways Christians understand it
1) The stepmother reading
This is the most common view. The man is sexually involved with his stepmother or his father’s wife. That is the reading that most directly fits the wording and the Old Testament background.
2) A relationship after the father’s death
Some think the father had died, and the woman was a widow. Even so, the relationship would still have crossed a serious family boundary. This view changes the family arrangement, but not the force of Paul’s rebuke.
3) A shorthand description of a broader scandal
Another cautious reading says Paul may be using a short phrase to identify a well-known scandal without giving every detail. That is possible, and it actually fits the style of the letter. Paul is writing to correct behavior, not to give a biography.
What the verse does not mean
This verse does not make every remarriage or blended-family situation suspect. It is much narrower than that.
It also does not mean Paul is mainly interested in shock value. His concern is holiness, repentance, and the church’s witness.
And it does not mean the passage settles every modern question about marriage law. Paul is addressing a specific church problem in Corinth, not writing a general family policy manual.

Verdict
1 Corinthians 5:1 is Paul’s short but serious description of a forbidden sexual relationship, most likely involving a stepmother or father’s wife. The verse is difficult because Paul does not give family-tree details, but he is not unclear about the moral issue. He sees the case as openly shameful and rebukes the church for treating it too lightly.
