1 Corinthians 5:1-13 - Immoral Behavior And Church Discipline
1 There goeth a common saying that there is fornication among you, and such fornication as is not once named among the gentiles: that one should have his father's wife. 2 And ye swell and have not rather sorrowed, that he which hath done this deed might be put from among you. 3 For I, verily, as absent in body, even so present in spirit, have determined already - as though I were present - of him that hath done this deed; 4 in the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of the Lord Jesus Christ, 5 to deliver him unto Satan, for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
6 Your rejoicing is not good. Know ye not that a little leaven soureth the whole lump of dough? 7 Purge therefore the old leaven, that ye may be new dough, as ye are sweet bread. For Christ our Easter lamb is offered up for us. 8 Therefore let us keep holiday, not with old leaven, neither with the leaven of maliciousness and wickedness - but with the sweet bread of pureness and truth.
9 I wrote unto you in an epistle that ye should not company with fornicators. 10 And I meant not at all of the fornicators of this world, either of the covetous, or of extortioners, either of the idolaters - for then must ye needs have gone out of the world - 11 but now I write unto you that ye company not together. If any that is called a brother, be a fornicator, or covetous, or a worshipper of images, either a railer, either a drunkard, or an extortioner: with him that is such see that ye eat not. 12 For what have I to do to judge them which are without? Do ye not judge them that are within? 13 Them that are without, God shall judge. Put away from among you that evil person.
