What Is Church Discipline in the Bible?

Church discipline is the practice of addressing persistent, unrepentant sin within the body of Christ. It is not punishment for the sake of vengeance but correction for the sake of restoration. Jesus laid down the procedure in Matthew 18:15-17: 'Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established. And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican.' This four-step process — private confrontation, witnesses, the whole church, and removal from fellowship — is designed to give the offender every opportunity to repent while protecting the purity of the church. The Apostle Paul applied this to the case of incest in the Corinthian church. A man was living with his father's wife, and the church was proud rather than grieved. Paul commanded, 'In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ, To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.' 'Delivering to Satan' meant removing the person from the protective fellowship of the church, exposing them to the consequences of their sin in the world. The goal was not destruction but salvation — 'that the spirit may be saved.' Church discipline is also preventive. Paul warned that 'a little leaven leaveneth the whole lump.' Unaddressed sin spreads and corrupts the entire congregation. The church must maintain standards that reflect God's holiness. But discipline must be exercised with great care. Paul warned against judging those outside the church: 'For what have I to do to judge them also that are without? do not ye judge them that are within? But them that are without God judgeth.' The church's authority extends only to its own members. Paul also warned against harshness: 'Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.' The spirit of discipline must always be gentle, humble, and hopeful. The goal is always restoration. Paul rejoiced when the Corinthian man repented and urged the church to forgive and comfort him, 'lest such an one should be swallowed up with overmuch sorrow.' Church discipline, when practiced biblically, preserves the church's purity, protects the gospel's reputation, warns the unrepentant, and ultimately seeks the restoration of wandering sheep.
