Wellll, I relieve you of that boundary hereby—please feel free to exhort me publicly where my offenses tend to occur. Others may learn from my sins and errors.
As the apostles said, we must obey God rather than men. God has commanded us to first privately, in love, intervene with a straying brother/sister. If that doesn’t work, then one or two additional faithful believers should become involved. If that fails, then and only then is the entire church/assembly engaged in the issue.
