|2 Thessalonians 3:6 |
6 Now we command you, brothers, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother who walks disorderly, and not after the tradition which he received from us.1
1 But now I write to you not to associate with anyone who bears the name of [Christian] brother if he is known to be guilty of immorality or greed, or is an idolater [whose soul is devoted to anything that usurps the place of God, and how they spend their free time defines what they are devoted to], or is a person with a foul tongue [railing, abusing, reviling, slandering], or is a drunkard or a swindler or a robber. You must not so much as eat with such a person.
And if you were not supposed to eat with such a person, obviously you were not supposed to attend a worship meeting of such people.
This is further amplified in this letter by verse 14: if any man does not obey our word in this letter, note that man, and have no company with him, so that he may be ashamed.
