1 Corinthians 5:1-8 Revised Standard Version (RSV)
Sexual Immorality Defiles the Church
5 It is actually reported that there is immorality among you, and of a kind that is not found even among pagans; for a man is living with 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 4 in the name of the Lord Jesus on the man who has done such a thing. When you are assembled, 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, that his spirit may be saved in the day of the Lord Jesus.[a]
6 Your boasting is not good. Do you not know that a little leaven leavens the whole lump? 7 Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our paschal lamb, has been sacrificed. 8 Let us, therefore, celebrate the festival, not with the old leaven, the leaven of malice and evil, but with the unleavened bread of sincerity and truth.
