1 Corinthians 5:1-5

AUV(i) 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].
