"An overseer, then, must be above reproach, the husband of one wife, temperate, prudent, respectable, hospitable, able to teach, not addicted to wine or pugnacious, but gentle uncontentious, free from the love of money. He must be one who manages his own household well, keeping his children under control with all dignity (but if a man does not know how to manage his own household, how will he take care of the church of God?); and not a new convert, lest he become conceited and fall into the condemnation incurred by the devil. And he must have a good reputation with those outside the church, so that he may not fall into reproach and the snare of the devil." (I Timothy 3:2-7)
