1 Corinthians 5

1It is actually reported that there is sexual immorality among you, and of a kind that is intolerable even among pagans: A man has his father’s wife. 2And you are proud! Shouldn’t you rather have been stricken with grief and have removed from your fellowship the man who did this? 3Although I am absent from you in body, I am present with you in spirit, and I have already pronounced judgment on the one who did this, just as if I were present. 4When you are assembled in the name of our Lord Jesus and I am with you in spirit, along with the power of the Lord Jesus, 5hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved on the Day of the Lord. 6Your boasting is not good. Do you not know that a little leaven works through the whole batch of dough? 7Get rid of the old leaven, that you may be a new unleavened batch, as you really are. For Christ, our Passover lamb, has been sacrificed. 8Therefore let us keep the feast, not with the old bread, leavened with malice and wickedness, but with the unleavened bread of sincerity and of truth. 9I wrote you in my letter not to associate with sexually immoral people. 10I was not including the sexually immoral of this world, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. 11But now I am writing you not to associate with anyone who claims to be a brother but is sexually immoral or greedy, an idolater or a verbal abuser, a drunkard or a swindler. With such a man do not even eat. 12What business of mine is it to judge those outside the church? Are you not to judge those inside? 13God will judge those outside. “Expel the wicked man from among you.”

Matthew Henry's Commentary

The apostle blames the Corinthians for connivance at an incestuous person; (1-8) and directs their behaviour towards those guilty of scandalous crimes. (9-13) 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. 9-13 Christians are to avoid familiar converse with all who disgrace the Christian name. Such are only fit companions for their brethren in sin, and to such company they should be left, whenever it is possible to do so. Alas, that there are many called Christians, whose conversation is more dangerous than that of heathens!
