1 Corinthians 5:9-13 - Church Discipline
9 I have written to you in the epistle not to mix with fornicators; 10 not altogether with the fornicators of this world, or with the avaricious and rapacious, or idolaters, since then ye should go out of the world. 11 But now I have written to you, if any one called brother be fornicator, or avaricious, or idolater, or abusive, or a drunkard, or rapacious, not to mix with him; with such a one not even to eat. 12 For what have I to do with judging those outside also? ye, do not ye judge them that are within? 13 But those without God judges. Remove the wicked person from amongst yourselves.
