5:5 {5} To {c} deliver such an one unto Satan for the {6} destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
(5) The one who is excommunicated is delivered to the power of Satan, in that he is cast out of the house of God.
(c) What it is to be delivered to Satan the Lord himself declares when he says, Let him be unto thee as a heathen and publican; Mt 18:17. That is to say, to be disfranchised and put out of the right and privileges of the city of Christ, which is the Church, outside of which Satan is lord and master.
(6) The goal of excommunication is not to cast away the excommunicate that he should utterly perish, but that he may be saved, that is, that by this means his flesh may be tamed, that he may learn to live to the Spirit.
5:5 To deliver such one unto Satan. Not only this one, but all such persons. To deliver unto Satan is to excommunicate; to extradite from the kingdom of God to the prince of this world. The expression is used in 1Ti 1:20.
For the destruction of the flesh. Fleshly desires had caused the sin. These must be destroyed. The humiliation of excommunication, the sense of one's lost condition, was well adapted to bring a repentance. Some have held that this meant to send some painful disease miraculously. I believe that the Latin fathers and Beza are right in understanding that it refers to the mortification of the offender, cast out, shunned by the church as a dead body. This person is ordered to be restored, having repented, and no mention is made of disease, in 2Co 2:7.
That the spirit may be saved. This is the object of all true discipline. If carried out, as in the early church, it was well calculated to bring to repentance. It was effective in this instance, as we learn from 2Co 2:6.
5:5 To deliver such an one - This was the highest degree of punishment in the Christian church; and we may observe, the passing this sentence was the act of the apostle, not of the Corinthians. To Satan - Who was usually permitted, in such cases, to inflict pain or sickness on the offender. For the destruction - Though slowly and gradually. Of the flesh - Unless prevented by speedy repentance.
5:1-8 The apostle notices a flagrant abuse, winked at by the Corinthians. Party spirit, and a false notion of Christian liberty, seem to have saved the offender from censure. Grievous indeed is it that crimes should sometimes be committed by professors of the gospel, of which even heathens would be ashamed. Spiritual pride and false doctrines tend to bring in, and to spread such scandals. How dreadful the effects of sin! The devil reigns where Christ does not. And a man is in his kingdom, and under his power, when not in Christ. The bad example of a man of influence is very mischievous; it spreads far and wide. Corrupt principles and examples, if not corrected, would hurt the whole church. Believers must have new hearts, and lead new lives. Their common conversation and religious deeds must be holy. So far is the sacrifice of Christ our Passover for us, from rendering personal and public holiness unnecessary, that it furnishes powerful reasons and motives for it. Without holiness we can neither live by faith in him, nor join in his ordinances with comfort and profit.
