I Believe Faithful Churches Must Practice Church Discipline

Church discipline is one of the least understood and most neglected responsibilities entrusted to the local church. In a culture that prizes individual autonomy and often equates love with unconditional acceptance, the idea of correcting a fellow believer can seem harsh or unloving. Even many evangelical churches avoid the subject altogether, fearing controversy or the loss of members. Yet the Lord Jesus Christ did not present church discipline as an optional practice reserved for unusual circumstances. He established it as an essential mark of a healthy church. For that reason, I believe faithful churches must practice church discipline—not because they delight in confrontation, but because they love Christ, His people, and His truth.

Church discipline begins with a proper understanding of the church itself. The local church is not merely a gathering of like-minded individuals or a voluntary association of religious consumers. It is the body of Christ, the household of God, and the pillar and buttress of the truth (1 Timothy 3:15). Those who join a local church publicly profess faith in Christ and commit themselves to living under His lordship alongside other believers. Membership carries both privileges and responsibilities. Among those responsibilities is the mutual commitment to encourage one another toward holiness and to lovingly confront one another when persistent sin threatens our fellowship with God and His people.

Jesus Himself established the pattern for church discipline in Matthew 18:15–17. He instructed believers to begin privately when a brother sins. If the individual refuses to listen, one or two others are brought along to confirm the matter. If repentance still does not occur, the matter is brought before the church. Finally, if the individual remains unrepentant, the church is to regard him as an unbeliever by removing him from membership and fellowship. This progression demonstrates that church discipline is never impulsive or vindictive. It is patient, careful, and always seeks repentance before separation.

The purpose of church discipline is restoration, not punishment. The goal is never to embarrass someone publicly or to satisfy a desire for justice. Rather, discipline is an expression of love that seeks to restore a wandering believer to fellowship with Christ and His church. Just as a loving parent disciplines a child for the child's good, so the church lovingly corrects its members because it desires their spiritual health. Hebrews 12 reminds us that God's own discipline is evidence of His fatherly love. The church reflects that same loving concern when it faithfully addresses persistent, unrepentant sin.

The apostle Paul provides a sobering example in 1 Corinthians 5. A man in the Corinthian church was engaged in blatant sexual immorality, and the congregation had done nothing to address it. Rather than mourning over the sin, they had become proud of their tolerance. Paul sharply rebuked the church and instructed them to remove the man from their fellowship. His concern was not merely for the sinner but for the purity of the entire church. "A little leaven leavens the whole lump," he warned. Unchecked sin spreads. When a church refuses to confront open rebellion against God's Word, it communicates that holiness is optional and that the gospel makes little practical difference.

Remarkably, even in this severe situation, Paul's ultimate goal remained restoration. In 2 Corinthians, many scholars believe the disciplined individual had repented, and Paul urged the church to forgive, comfort, and reaffirm their love for him. Biblical discipline is therefore never complete until repentance is met with joyful forgiveness and full restoration whenever possible. The church must be just as eager to restore the repentant as it is to correct the rebellious.

Church discipline also protects the witness of the gospel. Christians represent Christ before a watching world. When someone claims to follow Jesus while living in open, habitual, and unrepentant sin, that profession undermines the credibility of the gospel. The church cannot read hearts, but it is responsible to evaluate outward conduct. Church discipline does not declare who is or is not eternally saved; rather, it recognizes that an individual's persistent lifestyle is inconsistent with a credible profession of faith. By removing an unrepentant person from membership, the church truthfully communicates that such a life should not be identified with Christ.

Faithful discipline also protects the spiritual health of the congregation. Sin is never isolated. False teaching, divisive behavior, sexual immorality, greed, and persistent rebellion all have the potential to influence others. Scripture repeatedly warns that bad company corrupts good morals and that false doctrine spreads like gangrene. Loving shepherds therefore guard the flock by addressing dangers before they consume the church. This protective role is part of the responsibility Christ has entrusted to pastors and elders.

One reason church discipline has largely disappeared is that many churches have embraced an overly individualistic view of Christianity. Membership is often viewed as casual and temporary rather than covenantal. People move from church to church with little accountability, and leaders hesitate to exercise discipline for fear of driving people away. Yet the New Testament consistently presents believers as members of identifiable local congregations under recognized spiritual leadership. Genuine biblical fellowship includes mutual accountability because spiritual growth happens within committed relationships.

Church discipline must also be practiced with humility. Every believer is susceptible to temptation and sin. Paul instructs those who restore a fallen brother to do so with gentleness while watching themselves lest they too be tempted (Galatians 6:1). Discipline should never be motivated by pride, personal conflict, or a desire to control others. Those who confront sin must do so prayerfully, compassionately, and with tears when necessary. The church is not a courtroom seeking convictions but a family seeking restoration.

Likewise, discipline should never be exercised over matters of personal preference or secondary disagreements. Churches must distinguish between clear biblical sin and issues where faithful Christians may disagree. The New Testament reserves formal church discipline for serious, outward, and unrepentant sin or persistent false teaching that threatens the gospel and the unity of the church. Wisdom, patience, and careful adherence to Scripture are essential in every case.

Pastors bear a particular responsibility in leading churches to practice discipline faithfully. This requires courage, since such decisions are rarely popular. It also requires teaching, because congregations must understand why discipline is necessary before they can participate biblically. Churches that consistently preach the holiness of God, the seriousness of sin, the beauty of repentance, and the transforming power of the gospel are far better prepared to practice loving discipline when the need arises.

Ultimately, church discipline reflects the character of Christ Himself. Jesus is full of grace and truth. He welcomed repentant sinners while confronting hypocrisy and rebellion. He loved His church enough to die for her, and He continues to sanctify her so that she might be presented to Him in splendor, without spot or wrinkle (Ephesians 5:25–27). The church should share that same desire for holiness.

I believe faithful churches must practice church discipline because Christ commanded it, the apostles modeled it, and the health of the church depends upon it. Properly practiced, church discipline honors Christ, protects the purity of His church, strengthens its witness before the world, and lovingly calls wandering believers back to repentance. Though often difficult and sometimes painful, it is one of the clearest demonstrations that the church truly believes the gospel it proclaims. A church that refuses to discipline persistent, unrepentant sin ultimately fails to love its members, misrepresents the holiness of God, and neglects one of the Shepherd's most important commands.
