Paul noted that some in that congregation were “walking disorderly.” They were disregarding inspired counsel. During a previous visit, he gave this order: “If anyone does not want to work, neither let him eat.” Yet, some were still refusing to work to support themselves, although able to do so. Also, they were meddling in the affairs of others. How were Christians to treat such disorderly ones?​—2 Thess. 3:6, 10-12.

“Keep this one marked,” said Paul. The Greek word suggests taking special notice of this person. Paul addressed this directive to the whole congregation, not just the elders. (2 Thess. 1:1; 3:6) So individual Christians who might have noticed a fellow Christian disobeying inspired counsel would choose to “stop associating with” the disorderly one.

Did this mean that the person was treated as someone who was removed from the congregation? No, for Paul added: “Continue admonishing him as a brother.” So individual Christians would still associate with the marked one at meetings and in the ministry, but they would choose not to associate with him for social occasions or recreation. Why? “That he may become ashamed,” said Paul. As a result of the marking, the disorderly Christian might become ashamed of his conduct and change his ways.​—2 Thess. 3:14, 15.

How might Christians today apply this counsel? First, we would want to make sure that the conduct in question is actually “disorderly,” as Paul described. He was not talking about those who differ from us in matters of conscience or personal preference. And he did not mean those who simply have hurt our feelings. Rather, Paul had in mind specifically those who deliberately chose to disobey clear, God-given counsel.
