Excommunication is the formal, authoritative act of the local church to exclude an unrepentant member from the fellowship and sacramental life of the congregation. Far from being cruel, it is an act of love — both for the person being disciplined and for the integrity of the church. Christ himself instituted this practice (Matt. 18:15–17), and Paul commands it in cases of unrepentant sexual immorality, false teaching, and persistent divisiveness. The goal is always repentance and restoration (2 Cor. 2:6–8). The excommunicated person is to be treated "as a Gentile and a tax collector" — not with contempt, but as someone outside the covenant community who needs to be brought back in.
EXCOMMUNICATION, n. The act of ejecting a person from the communion of a church, by an ecclesiastical sentence. It is a censure or punishment inflicted on members of a church for gross offenses, depriving them of the rights and privileges of church membership.
Modern evangelical culture has largely abandoned church discipline as "unloving" and "judgmental." The result is churches that cannot distinguish members from the world, and congregations riddled with unrepentant sin. When everyone belongs regardless of belief or behavior, the word "member" means nothing and the church loses its power to be a witness. A church that fears excommunication more than it fears God has traded biblical love for cultural sentimentality.

• "The church excommunicated the unrepentant elder not in anger but in grief, praying for his restoration."
