4 Bible Verses about Fellowship With Wicked

Now I urge you, brothers, watch out for those who are causing divisions and occasions for falling [away from God over matters] contrary to the teaching you have learned, and withdraw from them [i.e., stop listening to their false teaching].

But I wrote to you not to associate with anyone claiming to be a [Christian] brother who is [guilty of being] sexually immoral, or greedy, or an idolater, or who speaks abusively, or a drunkard, or a swindler. Do not even eat [a social meal] with such a person.

Do not team up with unbelievers [i.e., in close relationships, such as marriage, etc.]. For what do righteousness and wickedness have in common? Or, what fellowship can light have with darkness?

Now we command you, brothers, in the name [i.e., by the authority] of our Lord Jesus Christ, that you people stay away from every brother [or sister] who lives an idle life [See note on I Thess. 5:14], and not according to the [inspired] tradition which you received from us.
