Paul writes:
“In the name of the Lord Jesus Christ, we command you, brothers and sisters, to keep away from every believer who is idle and disruptive and does not live according to the teaching you received from us. . . Take special note of anyone who does not obey our instruction in this letter. Do not associate with them, in order that they may feel ashamed. Yet do not regard them as an enemy, but warn them as you would a fellow believer.” 2 Thessalonians 3:6, 14-15
