Church Discipline: Repentance, Removal, and Renewal

Paul begins with the church’s identity: those sanctified in Christ Jesus and called to be saints. That identity does not permit Christians to say they belong to Christ while continuing to act like the world. God gave Israel laws of holiness not to squash freedom, but to show whose they were; likewise, redeemed and justified sinners are called to holiness in body, appetite, speech, and sexuality. Holiness cannot be postponed by the young or excused by the old. The church must fight for it together.

Paul confronts a case of blatant sexual immorality, a man taking his father’s wife, but his sharpest rebuke falls upon the church’s response. The Corinthians are arrogant because they have done nothing. Their silence is not love, wisdom, or Christian liberty. Their silence is pride. The claim that what happens in the bedroom stays in the bedroom turns grace into licentiousness and treats private sin as harmless, even though sin affects a person’s standing before God, the church’s holiness, and the church’s witness.

Matthew 18 and 1 Corinthians 5 place a real obligation upon Christ’s people to confront sin with grace, long suffering, God’s Word, and Christ’s forgiveness. Love does not look the other way while a brother or sister persists in open rebellion. Paul says the church ought to mourn, because tolerated sin calls for repentance not only from the sinner but also from the congregation that has countenanced it.

Paul then commands removal: “deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.” This extreme remedy is not immediate or careless excommunication. Church discipline requires patient steps, private confrontation, further witnesses, the involvement of elders, prayer, warnings, and only then, if repentance never comes, excommunication. Even that act belongs to Christ’s mercy, because only God knows the final judgment and the church still calls the hardened sinner to repent.

Paul’s command not even to eat with such a one does not require Amish shunning or forbid every form of contact. It forbids acting as though everything is fine. Fellowship cannot bless rebellion, whether through table fellowship, social invitations, or easy approval of a sinful life. The church must refuse to countenance what Christ calls evil while still seeking opportunities to call the sinner back.

Paul’s image of leaven shows why this matters. A little tolerated evil spreads through the whole lump. Christ, the Passover Lamb, calls His people to celebrate with the unleavened bread of sincerity and truth. The church therefore pursues holiness urgently, communally, and continually, rejoicing that Christ cleanses, renews, and enables His people to fight sin until He calls them home.

Key Takeaways

• 1. Holiness belongs to Christian identity. Christ does not merely forgive sin while leaving His people free to settle comfortably into it. Sanctification follows from belonging body and soul to a faithful Savior. Age, history, and personal weakness may explain a struggle, but they cannot cancel the call to fight. [08:58]
• 2. Silence toward sin is not love. Love considers the sinner’s standing before God, not merely the discomfort of a hard conversation. A church that sees open rebellion and does nothing has confused peace with faithfulness. Mourning over sin is more truthful than pretending it has no consequences. [18:40]
• 3. Discipline seeks repentance, not punishment alone. Excommunication is an extreme remedy for hardened, public, unrepentant rebellion, not a first response to every fall. Patient warnings and prayer show that the church seeks restoration rather than merely removal. Even severe discipline aims at the salvation of the sinner’s spirit on the day of the Lord. [25:20]
• 4. Fellowship must not normalize rebellion. Christians may still seek contact with a disciplined person, but they cannot participate in the fiction that everything is normal. Table fellowship, celebration, and public approval can communicate acceptance where repentance is absent. Holiness requires love that tells the truth about what sin has done. [33:54]
• 5. Christ cleanses His whole church. Leaven spreads quietly, and tolerated sin eventually affects the whole loaf. The church’s pursuit of purity is therefore urgent, communal, and continual. Christ’s grace gives reason for rejoicing, because He is the One who cleanses and renews His people.

Bible Reading

1 Corinthians 5:1-13
“It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father's wife. And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing. When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord. Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed. Let us therefore celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth. I wrote to you in my letter not to associate with sexually immoral people— not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. 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.” [00:59]

Matthew 18:15-17
“If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.” [18:10]

Leviticus 20:11
“If a man lies with his father's wife, he has uncovered his father's nakedness; both of them shall be put to death; their blood is upon them.” [10:52]

Observation questions

1. In 1 Corinthians 5, what sinful situation has been reported in the church, and how does Paul describe the church’s response to it? [13:14]
2. What does Paul say the church should do instead of being arrogant, and what does this reveal about the seriousness of tolerated sin? [19:10]
3. What steps for addressing sin are seen when Matthew 18:15–17 is considered alongside the patient process described for church discipline? [24:23]
4. In Paul’s picture of leaven, what happens when a small amount of tolerated evil remains in the church? [35:31]

Interpretation questions

1. Why is Paul’s rebuke directed not only toward the man in open sin but also toward the whole congregation? What does this show about the church’s shared responsibility for holiness? [37:21]
2. Paul says that removal from fellowship is meant so that the sinner’s spirit may be saved on the day of the Lord. How can a severe act of discipline be an act of mercy rather than merely punishment? [26:14]
3. How does Matthew 18 protect both the person confronting sin and the person being confronted from rash, private, or unfair judgments? [20:10]
4. What is the difference between maintaining contact with a disciplined person in order to call them to repentance and treating that person as though nothing is wrong? [33:47]

Application questions

1. Christ has made His people His own, and holiness belongs to their identity. In what area of life—speech, appetite, sexuality, relationships, entertainment, or something else—are you tempted to delay obedience or excuse a pattern that needs to change? [08:21]
2. When you become aware of a fellow Christian’s serious and ongoing sin, what makes you most likely to remain silent: fear, uncertainty, a desire to avoid conflict, or the belief that it is not your place? How could you respond with both humility and love? [18:22]
3. Is there someone in your life whom you need to approach more honestly—not to accuse or embarrass them, but to ask caring questions and point them toward Christ’s forgiveness? What would a gracious first conversation look like? [20:10]
4. In what ways can Christians accidentally communicate approval of a sinful situation through invitations, celebrations, social media responses, or casual conversation? How can you tell the truth without becoming cold or self-righteous? [33:29]
5. The call to holiness is communal, not merely private. What is one practical way this group can help one another fight sin more openly, wisely, and prayerfully? [41:12]
6. Paul calls believers to celebrate with sincerity and truth because Christ, the Passover Lamb, has cleansed them. How does Christ’s forgiveness give hope and strength for a real, continuing fight against sin rather than resignation or despair? [39:51]
