The Full Arc: Discipline → Restoration → Grace-Excelled
1 Corinthians 5:11-13
But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? God judges those outside. "Purge the evil person from among you."
Paul is addressing the Corinthian church, they had grown proud and tolerant of flagrant sin in their midst. And to make matters worse, the congregation wasn’t grieving these things; in fact they were boasting (v. 2, 6). To protect the church’s purity, and awaken the sinner to repentance, Paul commanded them to excommunicate the unrepentant sinner in order to honor Christ's name.
The church’s arrogance in refusing to act made it worse: tolerating what even the world condemned undermined their claim to holiness.
Modern parallels: When a church shrugs at a leader’s ongoing affair, a priests predatory behavior, or public advocacy of corrupt sexual ethics and identities that are contrary to Scripture, and the same principle applies.
What's a body [in Christ] to do?
Name the sin clearly. Call porneia [every kind of unlawful sexual intercourse] porneia, no euphemisms. And distinguish between the strugglers (those who confess and fight) from celebrators (those who defend and persist).
First follow the Matthew 18 process:
Private confrontation → 2–3 witnesses → tell the church → treat them as an outsider only if there is no repentance.
But Paul conditions this situation. His aim is restoration, not just removal (v. 5: "deliver to Satan…that his spirit may be saved." ). Excommunication is medicinal, not vindictive. The door stays open for repentance (2 Corinthians 2:6–8). But the condemnation is meant to protect the vulnerable. Sexual sin, especially within the body of Christ, often leaves victims. The church’s silence re-traumatizes. And when a crime occurs, reporting to civil authorities (Romans 13:1–4) is required.
Within the church, we're not to have association with fornicators, idolatrous people, covetous and corrupt extortionists. Yet within the world we cannot escape these people. Outside the church the world is filled with these people. And the church is sent into that world in order to be a light shining in and through them. Greedy people, idolatrous, sexually immoral; in the world we cannot escape them, but in the church we must be free from those wicked urges.
Quick Diagnostic Questions for The Church Elders
1. Is the sin public and persistent?
2. Has Matthew 18 been exhausted?
3. Are victims safe and supported?
4. Is the gospel being preached as the only power for change?
If yes to all, act swiftly. Purge the leaven because the Lamb has been slain. If no, slow down and be a shepherd. The church’s discipline is not a flex of power; it’s a cry of faith that Jesus’ blood is stronger than our worst sins, and His reputation is worth protecting at any cost.
Keep in mind always, discipline is a bridge, not a wall. There demands follow-up and practical steps for restoration.
What's Required?
Public confession Fruit: the sin ends, submits to accountability, makes restitution (Luke 3:8; 2 Corinthians 7:10–11).
Avoid the errors of Novatianism, of tolerance, and the "forgive and forget" attitude that offers no hope. Satan trys to trap churches either into bitterness ["He doesn’t deserve grace!"] or presumption ["Just let him back, no questions asked"]. Either way he wins.
Pray over him/her.
And follow the biblical teachings:
Exaltation (pride, egregious sin) → Humiliation (discipline, Church obeys) → Restoration (grace, man/woman repents)
"...see that you also excel in this grace..." (2 Corinthians 8:7)
Closing Prayer
Father of mercies and God of all comfort, You cast out the leaven by the blood of Your spotless Lamb, and You ran to the prodigal while he was still a long way off. Give Your church tears for the sinner, courage for the discipline, and open arms for the repentant. When we must remove, let it be with grief, not gloating. When we restore, let it be with joy, not suspicion. Keep us a city on a hill whose light is holiness, truth, and lavish love.
In the holy name of Jesus, our Passover and our Peace,
Amen.
