Sin in the Church Addressed

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

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.
