Titus 1:7-9

For it is necessary for a Bishop to be a man of virtue, as God's servant; not pushing himself forward, not quickly moved to wrath or blows, not desiring profit for himself; But opening his house freely to guests; a lover of what is good, serious-minded, upright, holy, self-controlled; Keeping to the true word of the teaching, so that he may be able to give comfort by right teaching and overcome the arguments of the doubters.
