“A Bishop then,” he says, “must be blameless, the husband of one wife.” This he does not lay down as a rule, as if he must not be without one, but as prohibiting his having more than one. For even the Jews were allowed to contract second marriages, and even to have two wives at one time. For “marriage is honorable,” (Heb. xiii. 4.) Some however say, that this is said that he should be the husband of one wife. “Blameless.” Every virtue is implied in this word; so that if any one be conscious to himself of any sins, he doth not well to desire an office for which his own actions have disqualified him. For such an one ought to be ruled, and not to rule others. For he who bears rule should be brighter than any luminary; his life should be unspotted, so that all should look up to him, and make his life the model of their own. But in employing this exhortation, he had no common object in view. For he too was about to appoint Bishops, (which also he exhorts Titus to do in his Epistle to him,) and as it was probable that many would desire that office, therefore he urges these admonitions. “Vigilant,” he says, that is, circumspect, having a thousand eyes about him, quicksighted, not having the eyes of his mind dimmed. For many things occur which permit not a man to see clearly, to see things as they are. For care and troubles, and a load of business on all sides press upon him. He must therefore be vigilant, not only over his own concerns, but over those of others. He must be well awake, he must be fervent in spirit, and, as it were, breathe fire; he must labor and attend upon his duty by day and by night, even more than a general upon his army; he must be careful and concerned for all. “Sober, of good behavior, given to hospitality.” Because these qualities are possessed by most of those who are under their rule, (for in these respects they ought to be equal to those who rule over them,) he, to show what is peculiar to the Bishops, adds, “apt to teach.” For this is not required of him that is ruled, but is most essential to him who has this rule committed to him.
