It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Gentiles, that one has his father's wife.
2You are puffed up, and didn't rather mourn, that he who had done this deed might be removed from among you.
3For I most certainly, as being absent in body but present in spirit, have already, as though I were present, judged him who has done this thing.
4In the name of our Lord Jesus Christ, you being gathered together, and my spirit, with the power of our Lord Jesus Christ,
5are to deliver such a one to Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
6Your boasting is not good. Don't you know that a little yeast leavens the whole lump?
7Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.
8Therefore let's keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.
9I wrote to you in my letter to have no company with sexual sinners;
10yet not at all meaning with the sexual sinners of this world, or with the covetous and extortioners, or with idolaters; for then you would have to leave the world.
11But as it is, I wrote to you not to associate with anyone who is called a brother who is a sexual sinner, or covetous, or an idolater, or a slanderer, or a drunkard, or an extortioner. Don't even eat with such a person.
12For what do I have to do with also judging those who are outside? Don't you judge those who are within?
13But those who are outside, God judges. "Put away the wicked man from among yourselves."

Summary

A man in the Corinthian church is in an incestuous relationship with his stepmother — a sin so scandalous that even pagans don't tolerate it — and the church, instead of mourning, is puffed up. Paul, though absent, has already passed judgment: the unrepentant offender is to be removed from the community, "delivered to Satan" for the destruction of the flesh, that his spirit might be saved on the day of the Lord. Their tolerance is a small yeast that will leaven the whole loaf; they must purge the old yeast because Christ their Passover has been sacrificed, and the new unleavened lump is who they really are. Paul clarifies his earlier instruction: he doesn't mean to avoid every sinful unbeliever (you'd have to leave the world), but to refuse table fellowship with any so-called brother living in unrepentant grievous sin. Outsiders God judges; insiders the church must judge — and remove the wicked person from among them.

Themes

  • Tolerated sin as a poison to the community
  • Mourning rather than boasting about church sin
  • Church discipline aimed at salvation
  • Christ as the Passover lamb already slain
  • Judging insiders, not outsiders

Key verses

  • 1 Corinthians 5:11 — “Not to associate with anyone who is called a brother who is a sexual sinner... Don't even eat with such a person.”
  • 1 Corinthians 5:13 — “Put away the wicked man from among yourselves.”
  • 1 Corinthians 5:6 — “A little yeast leavens the whole lump.”
  • 1 Corinthians 5:7 — “Christ, our Passover, has been sacrificed in our place.”

Context & background

Written c. AD 54-55 from Ephesus. The man's relationship with his "father's wife" — almost certainly a stepmother since Paul does not say the man married his own mother — was forbidden by Mosaic law (Leviticus 18:8) and by Roman law (Gaius, *Institutes* 1.63). Corinthian sexual permissiveness was infamous, but even there this crossed a line. The Corinthians' "boasting" likely reflects a misapplied freedom theology: in their view, the gospel released them from the body's claims, so what one did sexually no longer mattered. Paul's response cuts the opposite way: the body matters precisely because Christ has bought it. "Deliver to Satan" (v. 5) is excommunication — putting the man outside the protective community of the church, exposed to the realm of judgment (Paul uses similar language in 1 Timothy 1:20). The Passover metaphor (vv. 7-8) is dense — Jewish households purged all leavened bread from the home in preparation for Passover; now Christ's once-for-all Passover sacrifice requires the church to live in continual purity. "Don't even eat with such a person" (v. 11) likely includes the Lord's Supper but extends to ordinary table fellowship — a major social signal in the ancient world.

  1. Observe

    What specific sexual sin does Paul say was being reported in the Corinthian church (v. 1)?

  2. Observe

    What does Paul say about the role of "yeast" in verses 6-8, and what event does he connect it to?

  3. Interpret

    Paul instructs the church to "deliver such a one to Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus" (v. 5). What is the purpose of this severe discipline, and why does it not contradict Christian love?

  4. Interpret

    Paul distinguishes between associating with immoral people in the world (which is unavoidable) and associating with a "so-called brother" living in unrepentant sin (which he forbids). What principle drives that distinction?

  5. Apply

    The Corinthians were "puffed up" about tolerating the man's sin, perhaps boasting of their open-mindedness. Paul says they should have been mourning instead (v. 2). What does this teach about a healthy church culture's response to known, unrepentant sin among members?

  6. Apply

    Paul uses the Passover imagery of purging leaven (vv. 7-8) as a basis for church discipline. How does the fact that "Christ our Passover has been sacrificed" both motivate purity and set the tone for how discipline is pursued?
