Titus 1:6

If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly. (Notes, 1 Timothy 3:2) The thing dwelt on as the requisite in a bishop is a good reputation among those over whom he is to be set. The immorality of the Cretian professors rendered this a necessary requisite in one to be a reprover: their unsoundness in doctrine also made needful great stedfastness in the faith (Titus 1:9; Titus 1:13). Having faithful (believing) children. He who could not bring his children to faith, how shall he bring others? (Bengel.)

Not accused - not merely not riotous, but "not (even) accused of riot" [ asootias (G810)]: 'dissolute life' (Wahl).

Unruly - insubordinate: opposed to "in subjection."
