51 It is actually reported that there is sexual immorality among you, and of a kind that even pagans do not tolerate: A man is sleeping with his father's wife. 2 And you are proud! Shouldn't you rather have gone into mourning and have put out of your fellowship the man who has been doing this? 3 For my part, even though I am not physically present, I am with you in spirit. As one who is present with you in this way, I have already passed judgment in the name of our Lord Jesus on the one who has been doing this. 4 So when you are assembled and I am with you in spirit, and the power of our Lord Jesus is present, 5 hand this man over to Satan for the destruction of the flesh,[1][2] so that his spirit may be saved on the day of the Lord.
51 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife. 2 And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you. 3 For I verily, as absent in body, but present in spirit, have judged
51 It is actually reported that there is sexual immorality among you, and of a kind that is not tolerated even among pagans, for a man has his father's wife. 2 And you are arrogant! Ought you not rather to mourn? Let him who has done this be removed from among you. 3 For though absent in body, I am present in spirit; and as if present, I have already pronounced judgment on the one who did such a thing. 4 When you are assembled in the name of the Lord Jesus and my spirit is present, with the power of our Lord Jesus, 5 you are to deliver this man to Satan for the destruction of the flesh, so that his spirit may be saved in the day of the Lord.
51 I also received a report of scandalous sex within your church family, a kind that wouldn't be tolerated even outside the church: One of your men is sleeping with his stepmother. 2 And you're so above it all that it doesn't even faze you! Shouldn't this break your hearts? Shouldn't it bring you to your knees in tears? Shouldn't this person and his conduct be confronted and dealt with? 3 I'll tell you what I would do. Even though I'm not there in person, consider me right there with you, because I can fully see what's going on. I'm telling you that this is wrong. You must not simply look the other way and hope it goes away on its own. Bring it out in the open and deal with it in the authority of Jesus our Master. 4 Assemble the community - I'll be present in spirit with you and our Master Jesus will be present in power. 5 Hold this man's conduct up to public scrutiny. Let him defend it if he can! But if he can't, then out with him! It will be totally devastating to him, of course, and embarrassing to you. But better devastation and embarrassment than damnation. You want him on his feet and forgiven before the Master on the Day of Judgment.
51 It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Gentiles--that a man has his father's wife! 2 And you are puffed up, and have not rather mourned, that he who has done this deed might be taken away from among you. 3 For I indeed, as absent in body but present in spirit, have already judged (as though I were present) him who has so done this deed. 4 In the name of our Lord Jesus Christ, when you are gathered together, along with my spirit, with the power of our Lord Jesus Christ, 5 deliver such a one to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus.
51 I can hardly believe the report about the sexual immorality going on among you-something that even pagans don't do. I am told that a man in your church is living in sin with his stepmother. 2 You are so proud of yourselves, but you should be mourning in sorrow and shame. And you should remove this man from your fellowship. 3 Even though I am not with you in person, I am with you in the Spirit. And as though I were there, I have already passed judgment on this man 4 in the name of the Lord Jesus. You must call a meeting of the church. I will be present with you in spirit, and so will the power of our Lord Jesus. 5 Then you must throw this man out and hand him over to Satan so that his sinful nature will be destroyed and he himself will be saved on the day the Lord returns.
Matthew Henry's Commentary on 1 Corinthians 5:1-5
Commentary on 1 Corinthians 5:1-8
(Read 1 Corinthians 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.
