Just as support, here is just one of a few of the passages that are pertinent:
1 Timmothy 3:2 An overseer, then, must be above reproach, the husband of one wife, temperate, prudent, respectable, hospitable, able to teach,
3 not addicted to wine or pugnacious, but gentle, peaceable, free from the love of money.
4 He must be one who manages his own household well, keeping his children under control with all dignity
5 (but if a man does not know how to manage his own household, how will he take care of the church of God?),
6 and not a new convert, so that he will not become conceited and fall into the condemnation incurred by the devil.
7 And he must have a good reputation with those outside the church, so that he will not fall into reproach and the snare of the devil.
