Confronting a brother who has sinned requires treating him as a brother rather than a sinner, an approach grounded in the love that Jesus Christ commands His disciples to show one another. This love mirrors the compassion Jesus Christ displayed toward sinners, as seen when He gently instructed the adulteress to go and sin no more without condemnation. Foundational principles prepare for any such confrontation: humility that esteems others better than oneself and looks out for their interests rather than using the occasion to exalt oneself; careful avoidance of rash, harsh, or uncharitable judgments, since judgment is reciprocal and belongs ultimately to the Son; and proactive forgiveness that removes any grudge before approaching the brother, lest failure to forgive hinder one's own forgiveness from the Father. The extreme case recorded in I Corinthians 5 illustrates an exception rather than the rule. There the apostle Paul directed swift removal of a man guilty of an incestuous relationship because the sin had become public, scandalous, and divisive, yet even that action sprang from deep personal anguish and tears and led later to restoration once repentance occurred. Most sins, by contrast, remain private and should stay confined to as few people as possible. When confrontation becomes necessary, Matthew 18 supplies the precise sequence. The matter must involve an actual sin against God's law committed personally against the one who speaks. The brother is first addressed alone and informatively, without preaching or accusation, so that he may acknowledge the fault. If he refuses, one or two witnesses who can confirm the facts accompany the next conversation. Persistent refusal leads to involving church authorities, and only final unrepentance results in disassociation. Throughout, the goal remains restoration to fellowship rather than punishment, because the brother is part of Christ's body and the entire process must reflect the outgoing concern that preserves unity among those being prepared for the Kingdom of God.
