1 Corinthians 5
In 1 Corinthians 5, Paul turns his attention from internal divisions to a severe moral and spiritual crisis within the Corinthian congregation: an unaddressed case of gross sexual immorality involving a church member and his father's wife. Instead of grieving over this transgression, the Corinthian believers were inexplicably proud, boasting in their perceived spiritual tolerance or freedom. Paul writes with urgent apostolic authority to correct this dangerous complacency. He outlines a solemn process of church discipline, instructing the congregation to assemble and formally remove the unrepentant offender from fellowship. Drawing upon the rich imagery of Israel's Passover, Paul compares sin to leaven, explaining that even a small amount of hidden wickedness can corrupt the entire community. Because Christ, the ultimate Passover Lamb, has already been sacrificed, the church must live in purer worship and sincerity. Finally, Paul clarifies a previous misunderstanding regarding association with unbelievers, distinguishing between judging those outside the church and holding professing believers accountable. This chapter provides foundational principles regarding church purity, ecclesiastical discipline, and the holy calling of God's redeemed people.
1. Confronting Scandal and Exercising Discipline
1 Corinthians 5:1–5
1 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. 2 You are arrogant, and didn’ t mourn instead, that he who had done this deed might be removed from among you. 3 For 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. 4 In the name of our Lord Jesus Christ, when you are gathered together with my spirit with the power of our Lord Jesus Christ, 5 you are 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.
Commentary
- A Shocking Scandal Ignored: Paul confronts an extraordinary situation: a male member of the Corinthian church was involved in an ongoing sexual relationship with his father's wife (likely his stepmother). Such an act was explicitly forbidden under Mosaic law (Leviticus 18:8) and severely condemned even in Roman secular society. What disturbed Paul as much as the transgression itself was the church's arrogance and apathy; rather than mourning over this public dishonour to Christ, the congregation tolerated it under the guise of enlightenment or spiritual freedom.
- Apostolic Judgment and Gathering in Authority: Although absent physically, Paul exercised his apostolic authority in spirit, judging the matter as if present. He commanded the church to assemble formally in the name of the Lord Jesus Christ, acting with His delegated authority and power. Church discipline is not an arbitrary act of human anger or personal vendetta, but a solemn judicial proceeding carried out under the lordship of Jesus Christ and in accordance with His Word.
- Delivering to Satan for Redemptive Purposes: Paul directs the church to 'deliver such a one to Satan for the destruction of the flesh'. Excommunication formally places an unrepentant individual outside the protective fellowship of the church and into the domain of the world governed by Satan. The phrase 'destruction of the flesh' refers to breaking the person's sinful earthly passions or physical life, so that their spiritual pride might be shattered and their 'spirit may be saved in the day of the Lord Jesus'. The ultimate objective of biblical discipline remains redemptive, aiming at salvation rather than destruction.
Insight: Genuine love for a wandering Christian requires courageous discipline aimed at ultimate spiritual restoration, not passive tolerance that ignores destructive sin.
2. The Unleavened Life and the Passover Lamb
1 Corinthians 5:6–8
6 Your boasting is not good. Don’ t you know that a little yeast leavens the whole lump? 7 Purge 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. 8 Therefore 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.
Commentary
- The Danger of Spiritual Leaven: Paul rebukes the Corinthians' foolish boasting, reminding them that 'a little yeast leavens the whole lump'. In Jewish biblical imagery, yeast or leaven (Hebrew 'se'or', Greek 'zyme') frequently symbolized hidden, pervasive corruption. By permitting unrepentant sin to remain unaddressed within their fellowship, the Corinthian believers were endangering the moral and spiritual integrity of the entire congregation.
- Christ as the Passover Lamb: Paul connects the practice of church discipline to the Old Testament feast of Passover and Unleavened Bread (Exodus 12). Just as the Israelites had to thoroughly purge all leaven from their homes prior to the sacrifice, the church must cleanse itself from moral corruption. Paul explicitly declares that 'Christ, our Passover, has been sacrificed in our place'. Jesus' substitutionary death cleanses His people and establishes a holy covenant community.
- Keeping the Feast with Sincerity and Truth: Because the sacrifice of Christ has fulfilled the Passover, believers are called to live out a continual spiritual festival of holy living. They must strip away the 'old yeast' of malice, hypocrisy, and wickedness, and instead feed upon the 'unleavened bread of sincerity and truth'. The Greek word for sincerity ('eilikrineia') suggests pure, unmixed motives tested by light, while truth requires complete alignment with God's divine standard.
Insight: Because Jesus Christ died as our true Passover Lamb, our daily lives must reflect the moral purity and truth of those who have been redeemed from sin.
3. Church Boundaries and Moral Integrity
1 Corinthians 5:9–13
9 I wrote to you in my letter to have no company with sexual sinners; 10 yet not at all meaning with the sexual sinners of this world, or with the covetous and extortionists, or with idolaters, for then you would have to leave the world. 11 But 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 extortionist. Don’ t even eat with such a person. 12 For what do I have to do with also judging those who are outside? Don’ t you judge those who are within? 13 But those who are outside, God judges. “Put away the wicked man from among yourselves.”
Commentary
- Clarifying a Misunderstood Instruction: Paul clarifies a command given in a previous letter where he warned them not to associate with sexual sinners. The Corinthians had misinterpreted this as an order to completely isolate themselves from non-Christians. Paul explains that he did not mean the immoral people of this world—such as idolaters, greedy extortionists, or covetous individuals—because to avoid all worldly sinners, believers would literally have to leave the world entirely.
- Distinguishing Internal Accountability from External Evangelism: The apostle establishes a clear boundary between the church and the world. While Christians must engage non-believers with the gospel, they must strictly avoid close, approving fellowship with anyone 'who is called a brother' yet persistently practices gross sins such as sexual immorality, greed, idolatry, slander, drunkenness, or extortion. Paul commands the church not to even eat a common meal with such an unrepentant professing believer, maintaining social distance to highlight the breach in fellowship.
- God's Judgment and the Mandate for Purity: Paul asserts that God reserves the judgment of outsiders ('those who are outside') to Himself. The responsibility of the church leadership and congregation is to exercise internal discernment over its own members. Quoting Deuteronomy 17:7 and 22:24 ('Put away the wicked man from among yourselves'), Paul affirms that preserving church purity through righteous boundaries is a permanent divine requirement.
Insight: Christians are called to engage the lost world with redemptive grace while holding professing believers accountable to the holy standards of the Gospel.
Theological Significance
- Corporate Responsibility and Holiness: The local church is a single body whose overall spiritual health is directly impacted by individual members. Tolerating known, unrepentant sin within the fellowship dishonours Christ, damages Christian witness, and brings spiritual infection to the entire congregation.
- Substitutionary Atonement and Passover Fulfilment: Paul explicitly identifies Jesus Christ as 'our Passover' sacrificed in our place. This solidifies the foundational evangelical doctrine of substitutionary atonement and reveals how Old Testament covenant typologies find their complete fulfilment in the person and work of Christ.
- The Purpose and Scope of Church Discipline: Biblical discipline is never punitive or vindictive; its primary aims are the protection of the church's testimony, the prevention of corporate contamination, and ultimately the redemptive restoration of the offender's soul on the day of Christ's return.
- Jurisdiction of Ecclesiastical Discipline: God retains ultimate sovereign judgment over unbelievers outside the church, whereas He entrusts the church with spiritual governance and moral accountability over those who profess faith inside the local body.
Major Themes
- The necessity of biblical church discipline
- Corporate holiness and church purity
- Jesus Christ as the true Passover Lamb
- The subtle and spreading power of sin
- Proper boundaries between church accountability and worldly witness
- Spiritual pride versus godly sorrow over sin
- Integrity and sincerity in Christian living
Practical Applications
- Practice Redemptive Accountability in Fellowship: Churches and small groups must foster a culture of loving, humble, and firm accountability, where persistent sin is confronted rather than swept under the rug, always seeking the restoration of the offender.
- Purge Subtle Compromises Before They Spread: Individual believers must regularly search their own lives for hidden compromises, bad habits, and destructive attitudes, recognizing that unchecked personal sin will eventually affect their families and local churches.
- Engage Non-Believers Without Moral Isolationism: Christians must build redemptive relationships with unsaved people in their workplaces and communities to share Christ, without expecting non-Christians to live by Christian standards or adopting their sinful behaviors.
- Maintain Integrity in Church Leadership: Pastors and church leaders must reject the temptation to ignore scandals out of misplaced tolerance or fear of public reaction, prioritizing God's glory and the church's purity above reputation.
Final Insight
1 Corinthians 5 challenges the modern church to rediscover the sacred duty of corporate holiness and redemptive discipline. By exposing the Corinthians' arrogant tolerance of flagrant sin, Paul demonstrates that small compromises pollute the entire community of faith. The cross of Jesus Christ is not a license for moral carelessness, but the very reason for urgent purity: Christ our Passover Lamb was sacrificed to make us holy. As believers, we are called to live in sincere, unleavened worship, engaging the lost world with compassion while maintaining holy boundaries within the house of God. May the church today faithfully honor Christ by guarding its purity, walking in truth, and restoring broken sinners with loving firmness.
