"Particularly apparent here is Paul's sensitivity as a pastor: He avoids naming the culprit (vv. 5-8); he recognizes that Christian discipline is not simply retributive but also remedial (vv. 6, 7); he understands the feelings and psychological needs of the penitent wrongdoer (vv. 6-8); he appeals to his own conduct as an example for the Corinthians to follow (v. 10); and he is aware of the divisive operation of Satan within the Christian community (v. 11)."104
2:5 The person who caused sorrow to Paul and the Corinthians seems to have done so by insulting Paul either when Paul had been in Corinth last or since then. He was probably either the incestuous person referred to in 1 Corinthians 5:1-8105or someone who had been rude to Paul, probably by challenging his apostolic authority.106
2:6-8 Paul commended his readers for disciplining the offender, warned them against over-reacting, and urged them to convince him of their love for him. He "urged"this action, not ordered it, because true Christian love must be spontaneous and unforced or it ceases to be what it professes to be. The "majority"may refer to the whole church (Gr. hoi pleiones). The minority apparently held out for more severe discipline of this person. Thus Paul threw the whole weight of his apostolic authority behind forgiving as he had previously thrown it behind disciplining.
By accepting the offender after he repented the church would be confirming the Lord's forgiveness of him (cf. Matt. 16:19; 18:18; Luke 17:3; John 20:23).
"Discipline which is so inflexible as to leave no place for repentance and reconciliation has ceased to be truly Christian; for it is no less a scandal to cut off the penitent sinner from all hope of re-entry into the comfort and security of the fellowship of the redeemed community than it is to permit flagrant wickedness to continue unpunished in the Body of Christ."107
2:9 This action would also show that the church accepted Paul's apostolic authority. This was a test of its obedience to his authority. The reference to a previous letter seems to be another allusion to the severe letter (vv. 3-4).
2:10-11 Paul united in spirit with his readers. Indeed he had taken the initiative and forgiven the offending Corinthian before the other Corinthian Christians had. Paul deliberately understated the seriousness of the offense so no one would imagine that he considered himself virtuous for granting forgiveness readily.108This is the strongest evidence that the offense was not incest.
Paul had forgiven the offender in the presence of Christ, namely with the awareness that Jesus Christ was observing him. Jesus had taught that forgiveness of one another is a condition for receiving family forgiveness from the heavenly Father (Matt. 5:12, 14-15; 18:23-35; cf. Col. 3:13; Eph. 4:32). The apostle had also forgiven to preserve the unity that he enjoyed with this church. Third, he had forgiven the offender to frustrate Satan's desire to create discord in the church and between the church and Paul. The major emphases in these verses are on unity, moderation, and encouragement in the face of this problem.
