The argument for church discipline in 1 Corinthians 5 assumes at least a couple things. First, from the sinful man's perspective, he still wanted to be associated with the congregation. Paul confronted the flock for not removing the man; he had not removed himself. Whatever he was getting from his membership, he didn't want to lose it. Second, from the congregation's perspective, they should have something that the sinful man should want. Once removed and delivered over to Satan and the flesh, that bitter taste should turn him back to the fold.
In a similar remembrance that produced repentance, the prodigal son remembered all the blessings in his father's house. The difference for the prodigal, of course, is that he had left on his own whereas the disciplined man was removed. But what happened to the prodigal would hopefully happen to the disciplined man: he would remember all the blessings among God's people.
So part of our strategy for purity, preventative and remedial, is joy around the Lord’s Table. We share the blessings of salvation in communion, food for our faith and fellowship among the body in such a way as to fix in a man's mind something desirable. In the case of a disciplined man, the Lord may use remembrance of the shared bread and wine to draw him back. For us, we are encouraged week by week to not want sin more.
A couple Sunday mornings ago we welcomed to the Lord’s table two first-timers. They made their public profession of faith in the waters of baptism the previous Sunday evening, and we want for their first communion to be one of many sweet and serious celebrations. May our proclamation of the Lord's death until He comes be loud and compelling.
