appointed and approved

Titus 1:5-9

5 For this reason I left you in Crete, that you should set in order the things that are lacking, and appoint elders in every city as I commanded you-- 6 if a man is blameless, the husband of one wife, having faithful children not accused of dissipation or insubordination. 7 For a bishop must be blameless, as a steward of God, not self-willed, not quick-tempered, not given to wine, not violent, not greedy for money, 8 but hospitable, a lover of what is good, sober-minded, just, holy, self-controlled, 9 holding fast the faithful word as he has been taught, that he may be able, by sound doctrine, both to exhort and convict those who contradict.

1 Tim. 5:17

17 Let the elders who rule well be counted worthy of double honor, especially those who labor in the word and doctrine.
