Such a man ought not to command, but to obey. A ruler must be brighter than every lamp and must lead a blameless life, so that all may look upon him and order their own life according to his" (Chrysostom).
"The husband of one wife" does not mean that he must not have two wives at once, for this is forbidden to every Christian. It means that he has been married once, that he is a man of one marriage. A man married to a second wife should not be chosen as bishop.
Ambrosiaster writes: "Although having a second wife is not forbidden, one worthy of the episcopate must refrain even from what is permitted to others, because of the loftiness of this rank. The one who desires it must be incomparably above all."
Nor does this mean that he must necessarily be married. Blessed Theophylact writes: "In saying this, the Apostle does not legislate that a bishop must necessarily be married. How could the one who said, 'I wish that all men were as I myself am' command this?" (cf. 1 Cor 7:7).
To the same degree that a twice-married man is unfit for the episcopate, an unmarried man is more fit than one married once. Therefore, whenever possible, unmarried men were chosen not only as bishops, but also as priests. They served God without worldly care.
The rank of ascetics supplied such persons. It was born together with Christianity and was blessed by the Apostles and established in the Church.
But how can a bishop also be married? First, as Theodoret understands it, bishop here means presbyter. The true bishops were the secondary Apostles, such as Titus and Timothy, and they were celibate.
Probably, in other places also, persons like them were appointed to the episcopate proper. Second, necessity compelled it. Virginity had not yet become so widespread that a virgin could be found everywhere, although its foundation had been laid.
Meanwhile bishops were needed. Therefore they were chosen from those who, although married, lived in continence.
Blessed Theodoret writes: "The pagans did not practice virginity, and the Jews did not permit it, because they regarded fruitfulness as a blessing. Since at that time it was not easy to find those who preserved bodily purity, the Apostle Paul commands that those in the married state who honored chastity be ordained."
Chrysostom said even before him: "If a man bound by the bonds of marriage inevitably cares for worldly things, and a bishop must not care for worldly things, why did the Apostle say, 'the husband of one wife'?
Some think that here he points to a bishop who would be free from the bonds of marriage. If this is not what is meant, then it means that, having a wife, he can live as though he had none."
"Sober." Sobriety looks sharply over everything that happens in the soul. It gives place and movement to what is good, and rejects and drives out what is not good. Thus it governs well the course of the inner life, from which the outer life is ordered by itself.
Episcopal sobriety watches over everything that happens in his flock. It confirms what is good and corrects what is not good. The bishop watches especially sharply to see whether wolves are creeping in, not sparing the flock.
When he sees such wolves, he drives them away with the staff of his shepherdhood. He is appointed watchman over the house of God. Therefore he must vigilantly guard this house.
"He must be watchful and able to foresee how one ought to act" (blessed Theodoret). He must "be sharp-sighted, always wakeful, attentively observant, so as to see everything and always be ready for every necessary work" (blessed Theophylact).
"Sober, that is, he must be far-seeing and have a thousand eyes on every side. He must be penetrating and must darken his mental sight with nothing. There are many occurrences that do not allow one to see clearly how to act.
Therefore he must be sleeplessly watchful, caring not only for his own affairs, but also for what concerns others. He must keep vigil, burn in spirit, and, so to speak, breathe fire.
He must bear the labors and duties of his rank with greater zeal than a general who goes around the army by day and night. He must have care and concern for everything" (Chrysostom).
"Chaste." Since bodily chastity has already been mentioned in the words "the husband of one wife," here by chastity one should understand "progress of the soul" (blessed Theodoret). It means sound-mindedness, or prudence, both in his own conduct and still more in managing the affairs of the flock.
As neat clothing sits well on the whole body, with everything measured, fitting, and becoming, so affairs conducted prudently should adorn the bishop's countenance with good order. Let him be katestalmenos (see blessed Theophylact).
"Reverent, honorable." These two words correspond to the one Greek word kosmion, which blessed Theophylact interpreted as semnoprepe. Our Slavonic translation probably wished to express more fully the meaning of this latter word.
It means becomingly honorable, and shows that the bishop's appearance must shine with such sacred beauty as calls forth universal respect.
Blessed Theodoret writes: "He must be dignified in speech, appearance, gaze, and gait, so that the good order of the soul may be visible even in the body."
"Hospitable," that is, "willingly receiving strangers" (blessed Theodoret). "If he is welcoming, gracious, and merciful only to the local inhabitants, he suffers from partiality. He must be still more generous toward strangers, for this more clearly testifies to his brotherly love" (blessed Theophylact).
"Apt to teach." "Many among the subordinates also possess the qualities mentioned before this, prudence, reverence, and hospitality, as Oecumenius says. They too must be equal to their rulers in this respect.
Therefore, showing the bishop's distinctive excellence, the Apostle added, 'apt to teach.' This is no longer required of the subordinate, but it is required above all of the one to whom this office of the episcopate has been entrusted" (Chrysostom).
"By this the Apostle means not one distinguished by eloquence, but one trained in divine things and able to give proper counsel" (blessed Theophylact).
"Apt to teach," didaktikon, expresses that a bishop must be so full of teaching that, whenever the occasion arises, teaching flows like a river from his mouth.
He must always be able to fulfill, and actually fulfill, what the Apostle later wrote in the Second Epistle: "Preach the word; be urgent in season and out of season; reprove, rebuke, exhort, with all longsuffering and teaching" (2 Tim 4:2).
