Be blameless before God, and an example of good works...

"For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre;

But a lover of hospitality, a lover of good men, sober, just, holy, temperate;

Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers." Titus 1:7-9, KJV
