Titus 1:6-9 RSV

6 if any man is blameless, the husband of one wife, and his children are believers and not open to the charge of being profligate or insubordinate.
7 For a bishop, as God's steward, must be blameless; he must not be arrogant or quick-tempered or a drunkard or violent or greedy for gain,
8 but hospitable, a lover of goodness, master of himself, upright, holy, and self-controlled;
9 he must hold firm to the sure word as taught, so that he may be able to give instruction in sound doctrine and also to confute those who contradict it.
