2 And ye are puffed up, and did not rather mourn, that he that had done this deed might be taken away from among you. 3 For I verily, being absent in body but present in spirit, have already as though I were present judged him that hath so wrought this thing, 4 in the name of our Lord Jesus, ye being gathered together, and my spirit, with the power of our Lord Jesus, 5 to deliver such a one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus. 6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
7 Purge out the old leaven, that ye may be a new lump, even as ye are unleavened. For our passover also hath been sacrificed, [even] Christ:
Matthew Henry's Commentary on 1 Corinthians 5:2-7
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.
