Explanation

Jesus outlined discipline process (Matthew 18:15-17): 1) Private confrontation, 2) Bring witnesses if unresolved, 3) Tell the church, 4) Treat as outsider if still unrepentant. Goal is restoration, not punishment.

Paul instructed removing unrepentant sinners from fellowship (1 Corinthians 5) to protect church purity and shock the sinner into repentance. But when they repent, fully restore them (2 Corinthians 2).

Discipline must be done in love, not self-righteousness. It applies to members, not outsiders. Churches balance accountability with grace. The goal is always reconciliation – restoring both relationship with God and community.
