When your brother sins

Jesus gives a clear, step‑by‑step process for what to do when your brother sins against you in this passage.
Those steps are:
1. Go privately, one-on-one. “If your brother or sister sins, go and point out their fault, just between the two of you.

2. If they won’t listen, take one or two others. “…so that every matter may be established by the testimony of two or three witnesses.”

3. If they still refuse, tell it to the church.

4. If they refuse even then, treat them as a pagan or tax collector. This means there is a change in relational status when there is persistent refusal to repent.
