Titus 1:5-9
"This is why I left you in Crete, so that you might put what remained into order, and appoint elders in every town as I directed you—if anyone is above reproach, the husband of one wife, and his children are believers and not open to the charge of debauchery or insubordination."
The qualifications in Titus are similar to 1 Timothy 3, but with an emphasis on family. 'Believing children' — the leader’s home is the laboratory of his leadership. The central qualification: 'He must hold firm to the trustworthy word as taught, so that he may be able to give instruction in sound doctrine and also to rebuke those who contradict it' (1:9).
