1 Corinthians 5New American Bible (Revised Edition) (NABRE)
B. Moral Disorders[a]
A Case of Incest.[b] 1 It is widely reported that there is immorality among you, and immorality of a kind not found even among pagans—a man living with his father’s wife. 2 And you are inflated with pride.[c] Should you not rather have been sorrowful? The one who did this deed should be expelled from your midst. 3 I, for my part, although absent in body but present in spirit, have already, as if present, pronounced judgment on the one who has committed this deed, 4 in the name of [our] Lord Jesus: when you have gathered together and I am with you in spirit with the power of the Lord Jesus, 5 you are to deliver this man to Satan[d] for the destruction of his flesh, so that his spirit may be saved on the day of the Lord.
6 Your boasting is not appropriate. Do you not know that a little yeast[e] leavens all the dough? 7 [f]Clear out the old yeast, so that you may become a fresh batch of dough, inasmuch as you are unleavened. For our paschal lamb, Christ, has been sacrificed. 8 Therefore, let us celebrate the feast, not with the old yeast, the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth.
9 [g]I wrote you in my letter not to associate with immoral people, 10 not at all referring to the immoral of this world or the greedy and robbers or idolaters; for you would then have to leave the world. 11 But I now write to you not to associate with anyone named a brother, if he is immoral, greedy, an idolater, a slanderer, a drunkard, or a robber, not even to eat with such a person. 12 For why should I be judging outsiders? Is it not your business to judge those within? 13 God will judge those outside. “Purge the evil person from your midst.”
