1 Corinthians 5
It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the disbelievers, that one has his father's wife. 2You are puffed up, and didn't rather mourn, that he who had done this deed might be removed from among you. 3For I most assuredly, as being absent in body but present in spirit, have already, as though I were present, judged him who has done this thing. 4In the name of our Lord 'Isa al-Masih, you being gathered together, and my spirit, with the power of our Lord 'Isa al-Masih, 5are to deliver such a one to Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord 'Isa.
6Your boasting is not good. Don't you know that a little yeast leavens the whole lump? 7Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed al-Masih, our Passover, has been sacrificed in our place. 8Therefore let us keep the feast, not with old yeast, neither with the yeast of malice and wickedness, but with the unleavened bread of sincerity and truth. 9I wrote to you in my letter to have no company with sexual sinners; 10yet not at all meaning with the sexual sinners of this world, or with the covetous and extortioners, or with idolaters; for then you would have to leave the world. 11But as it is, I wrote to you not to associate with anyone who is called a brother who is a sexual sinner, or covetous, or an idolater, or a slanderer, or a drunkard, or an extortioner. Do not even eat with such a person. 12For what have I to do with also judging those who are outside? Don't you judge those who are within? 13But those who are outside, Allah judges. "Put away the evil from the midst of you." [1]
