[Firm Foundation, Vol. 114, No. 7, July 1999, p. 20.] Jesus gave his disciples specific instructions for dealing with a Christian who sins against a brother (Matthew 18:15-17).  His lesson shows how a small personal offense can escalate into a deep public sin.  If the sinner is unwilling to repent after three sincere overtures from the offended brother, other witnesses, and, finally, “the church” intense magnification of the sin occurs.  In this instance, Jesus tells us we must let the sinner be to us “like a heathen and a tax collector” (v. 17). The modern church has almost disavowed this part of Jesus’ divine plan.  Not many elders will even consider it.  Few sermons mention it.  As a result Christians in the pew have no clue about it. But Jesus’ words are clear and understandable.  They form a series of imperative commands.  Obedience to these commands, in this circumstance, is compulsory for everyone who would be his disciple. Harshness or lack of love was not in Jesus’ mind or on his lips.  His dual concerns were the restoration of the sinner and the protection of innocent Christians from the leavening influence of sin.  He wanted his disciples to know that withdrawal of fellowship within the local congregation is the tool of last resort in pursuing these noble spiritual goals. The Comforter led the apostles into explicit affirmation of Jesus’ discipline of withdrawal.  Paul admonished the Thessalonians to “note,” “withdraw” from and refuse to “keep company” with “busybodies” in the church
