Yet count him not as an enemy, but admonish him as a brother.
All Commentaries on 2 Thessalonians 3:15 Go To 2 Thessalonians 3
Augustine of Hippo
AD 430
Here it is as though doves are quarreling together. The apostle said, “If anyone fails to obey our word by this letter, mark that person and do not mix with him.” There’s the quarrel. But notice how it’s a quarrel of doves, not of wolves. He immediately added, “And do not regard him as an enemy, but rebuke him as a brother.” A dove is loving even when it is beating; a wolf hates even when it is being charming.
