Excommunication is the formal act of removing a member from participation in the church community due to persistent, unrepentant sin or actions that contradict the church’s teachings.

Purpose of Excommunication

1. Correction: Encourage the individual to recognize their wrongdoing, repent, and restore their relationship with God and the church (1 Corinthians 5:5).
2. Protection: Safeguard the moral and spiritual integrity of the church community (1 Corinthians 5:6).
3. Warning: Serve as an example to others about the seriousness of sin and disobedience (1 Timothy 5:20).

Process of Excommunication

1. Private Confrontation (Matthew 18:15): An individual is approached privately to address their sin.
2. Escalation (Matthew 18:16-17): If they remain unrepentant, others are brought in to counsel them, followed by church leadership involvement.
3. Formal Exclusion: If there is still no repentance, the individual is removed from church membership and barred from participating in communal activities such as the Eucharist.

Consequences of Excommunication

• Loss of Fellowship: Exclusion from communal worship and sacraments.
• Potential Restoration: If repentance occurs, the church often welcomes the individual back into full fellowship (2 Corinthians 2:6-8).

Biblical Basis:

• Matthew 18:17: “If they refuse to listen even to the church, treat them as you would a pagan or a tax collector.”
• 1 Corinthians 5:5: “Hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved on the day of the Lord.”
• Titus 3:10: “Warn a divisive person once, and then a second time. After that, have nothing to do with them.”
