1 Corinthians 5:9-13 - Church Discipline
9 I told you, in my letter, not to associate with immoral people- - 10 Not, of course, meaning men of the world who are in immoral, or who are covetous and grasping, or who worship idols; for then you would have to leave the world altogether. 11 But, as things are, I say that you are not to associate with any one who, although a Brother in name, is immoral, or covetous, or an idolater, or abusive, or a drunkard, or grasping-no, not even to sit at table with such people. 12 What have I to do with judging those outside the Church? Is it not for you to judge those who are within the Church, 13 While God judges those who are outside? 'Put away the wicked man from among you.'
