How Paul curses the man who committed fornication with his stepmother.
5 There is a report abroad that there is fornication among you, and such fornication as is not once named among the Gentiles: that a man should have his father’s wife. 2 And you swell, and have not rather sorrowed, so that he who has done this deed might be put out from among you. 3 For indeed I, as absent in body yet present in spirit, have determined already (as though I were present) concerning him who has done this thing, 4 in the name of our Lord Jesus Christ, when you are gathered together, and my spirit, with the power of the Lord Jesus Christ, 5 to deliver him to Satan for the destruction of the flesh, so that the spirit may be saved in the day of the Lord Jesus.
6 Your complacency is not good. Do you not know that a little leaven sours the whole lump of dough? 7 Purge therefore the old leaven, so that you may be new dough, as you are sweet bread. For Christ our Passover lamb is offered up for us. 8 Therefore let us keep holy day – not with old leaven, neither with the leaven of immorality and wickedness, but with the sweet bread of pureness and truth.
9 I wrote to you in an epistle that you should not keep company with fornicators. 10 And I did not at all mean the fornicators of this world, or the covetous, or swindlers, or idolaters, because then you would need to go out of the world. 11 But now I write to you not to keep company together with anyone called a brother who is a fornicator, or covetous, or a worshipper of images, or a railer, or a drunkard, or a swindler. With such a one, see that you do not eat. 12 For what have I to do with judging those who are outside? Do you not judge those who are within? 13 Those who are without, God will judge. Put away from among you that evil person.
