Matthew 18:15
15“If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother.
Discipline begins in private love, not public spectacle. The aim is explicit: gain your brother—restore fellowship, not win an argument.
Grace supplies sincere means. The offended goes; the offender may listen. Responsibility is mutual—courage to speak and freedom to repent—without skipping to shame that hardens rather than heals.
Christ orders the first step: go alone. Covering a brother’s fault as far as possible protects charity while still pursuing truth.
This is Christ’s ordinance for His household, not optional etiquette. The Spirit often uses a quiet word as the means of reclaiming; the goal is gain, matching the Shepherd who seeks the stray.
