1 It has actually been reported [to me] that there is a case of sexual immorality among you that is unheard of, even among the [unconverted] Gentiles. One of you is having sex with his stepmother. 2 And you are arrogant [about it] instead [of being ashamed]. Should you not be grieved to the point of removing from your fellowship the person who has done this [terrible] deed? 3 For although physically absent [from you], I am truly present with you in spirit and have already judged the person who did this [terrible] thing, just as if I were there [in person]. 4 [I command you], when you people are assembled together, with my spirit [also present], in the name [i.e., by the authority] and power of our Lord Jesus, 5 to turn such a person over to Satan for his body to be destroyed [Note: This probably refers to his removal from their fellowship. See verse 2], in order for his spirit to be saved in the day of the Lord [i.e., the judgment day]. [Note: This implies that his removal from their fellowship will have produced a genuine repentance before that time].
6 Your boasting is not good. Do you not know that a little yeast can leaven the whole batch of dough? 7 Get rid of the old yeast [i.e., of sin, and especially the unrepentant sinner], so that you can be a new batch of dough, without yeast in it [i.e., a godly church without unrepentant sinners in it] as [I know] you really are. For our Passover [Lamb], Christ, has already been sacrificed. 8 So, we should observe the Festival [i.e., live the Christian life], but not with the old yeast [i.e., old sinful ways], such as the leavening [effect] of evil and wickedness, but with the unleavened bread of sincerity and truth.
9 I wrote you in my letter not to associate with sexually immoral people. 10 I did not mean the sexually immoral people of this world, or with greedy people and swindlers, or with idolaters. For [to do this] you would have to go out of the world. [Note: If taken literally, this implies that there are no sinful people outside our planet]. 11 But I wrote to you not to associate with anyone claiming to be a [Christian] brother who is [guilty of being] sexually immoral, or greedy, or an idolater, or who speaks abusively, or a drunkard, or a swindler. Do not even eat [a social meal] with such a person. 12 (OMITTED TEXT) 13 For what business is it of mine to judge outsiders? [i.e., non-Christians]; God judges them. But should you not judge those people who are inside? [i.e., Christians]. [So], remove the evil person from your fellowship [See Deut. 17:7].
