"Thus, first, he must be blameless, ανεγκλητος. This very thing is expressed by another word in the Epistle to Timothy, I think, namely ανεπιλημπτος, irreproachable (see 1 Tim 3:2).
Not only at the time when he is chosen and appointed should he have no guilt or sin upon himself, having washed away his stains only just before this by a new conversion and repentance.
Rather, he must be such that his conscience does not gnaw at him for any sin since the time of his regeneration in Christ, that is, since baptism.
Otherwise, how will the presider of the Church be able to remove an evil man from her midst when he himself has fallen into the same vice?
Or how will he freely reproach one who sins when, secretly in his heart, he knows that he himself has allowed what he rebukes in another?" (Blessed Jerome).
"The husband of one wife," that is, not twice married. The Apostle honored marriage, since he did not set it as a barrier to receiving the rank of priesthood.
Yet he also gave no indulgence to marital pleasures, since he denied this rank to those twice married. On the one hand, continence is in view; on the other, devotion to one woman.
Both presume qualities that can serve as a guarantee that the one chosen can govern well the Church entrusted to him.
Saint Chrysostom says, "Why does the Apostle present such a man? He stops the mouths of heretics who condemned marriage, showing that this matter is not at all blameworthy.
Rather, it is so honorable that one may even ascend to the sacred throne while married. At the same time, he reproaches incontinent people, not permitting one to receive this authority after a second marriage.
Indeed, if a man has not preserved goodwill toward the wife who died, can he be a good presider? What reproach will he not incur?
You know, all of you know, that although the laws do not forbid entering a second marriage, this matter is nevertheless subject to many reproaches.
The Apostle wishes the ruler to give those subject to him no occasion for reproach."
Blessed Jerome looks here not so much at the act itself as at the inner disposition that the Apostle wished to instill by these words.
"The words 'husband of one wife' must be understood so that it does not follow that every man married once is thereby better than one married twice.
Rather, this was said to show that it is easier for one to incline others toward one marriage and continence when, in giving such a lesson, he teaches more by his own example.
Let us suppose that some young man lost his wife and, being overcome by bodily need, took another. But after soon losing her also, he resolved thereafter to live in continence from marital pleasures.
Let us take another man who had one wife until old age and never ceased bodily relations with her. Which of these two is better, more continent, and purer?
Certainly the one who, after suffering misfortune even in the second marriage, then began to live purely and holily. It is not the one who, even in old age, did not refrain from embraces with his wife.
Therefore let the one chosen for the priesthood not applaud himself because he was married only once, as though he were better than every man twice married.
In his election, fortune, namely not losing his wife, may have had more part than good free choice, namely preserving continence.
Some understand this passage as meaning that a man who has two wives at once should not be chosen as bishop. Others interpret it altogether perversely.
Montanus and the followers of Novatus's schism, who appropriated for themselves the name of continent and pure, think on the basis of this passage that second marriages are forbidden to Christians.
Yet the Apostle prescribed one marriage only for bishops and presbyters, while granting indulgence to others in this respect.
Tertullian also wrote a heretical book on monogamy. Anyone who reads the Apostle without prejudice cannot fail to see that he goes against the Apostle."
"Having faithful children, not accused of debauchery or insubordination." It is necessary that the children of the one chosen be believers and not subject to reproach for fornication, insubordination, or obstinacy.
To have one wife and to be blameless depends on a man's free choice. But children being disorderly is not always the parents' fault.
Therefore it is not wrong to add that the Apostle means here those cases in which the children are disorderly through the parents' fault, through their inability to direct them properly or through negligence in this matter.
But the Apostle did not single out these cases, because they were very rare. Perhaps it was also because, even if children are bad through no fault of the father, some shadow still falls on him.
The Apostle wants no one to see any stain on the chosen man. He wants him to be manifestly irreproachable in everything before all.
Saint Chrysostom sees here a parent who is guilty of the disorder of his children. Affirming that such a man is rightly not chosen as bishop, he explains this rule as follows.
"For," he says, "how can one who could not teach his own children be a teacher of others?
If he could not order those whom he had with him from the beginning, whom he raised, and over whom he had authority both by law and by nature, how can he be useful for those who are not his own?
If the father's carelessness had not been great, he would not have allowed those over whom he had authority from the beginning of their life to become evil.
It is impossible, truly impossible, for one who from the beginning was raised with great diligence and surrounded by care to become evil. Sins are not by nature able to be stronger than such care.
But if he counted the upbringing of children a secondary matter, caring only for property and not having proper concern for them, then for this reason also he is unworthy of the sacred rank.
If, where nature itself urged him, he had so little love or was so foolish that he cared more for property than for them, how can he be raised to the episcopal throne and to such a degree of authority?
If he could not raise his children, he deserves great condemnation for sloth. If he did not try, he deserves great condemnation for lack of love.
Therefore how can one who neglects his own children care for those of others?"
Blessed Jerome distinguishes fathers who are not guilty of their children's disorder. Nevertheless, he leaves the apostolic rule in full force.
He does this not because the children's faults make innocent parents guilty of them, but because otherwise the bishop's freedom of speech will be constrained and cut off.
He writes, "For a bishop or presbyter to be without fault and have one wife are requirements that lie within our power.
But what follows, to have faithful sons not subject to reproach for debauchery or insubordination, consists of requirements that do not lie within our power.
Therefore, if parents raised their children well and from youth taught them to keep the Lord's commandments, but they later became corrupted and gave themselves over to vice and lack of restraint, does the blame fall on the parents?
Do the sins of the son stain the holiness of the innocent father? Isaac, for example, certainly taught his son Esau every good thing.
Yet Esau proved to be both a fornicator and impious, so much so that he sold the sacred right of his firstborn status for one meal (see Gen 25).
So also Samuel, who was such that in the day of need he cried out to the Lord for Israel, and the Lord thundered with a great voice against the foreigners, the enemies of Israel, and they fell (cf. 1 Sam 7:10).
Yet Samuel had children who turned aside after greed, accepted gifts, and proved such unjust judges that, on this occasion, the people of Israel asked for a king after the example of other nations (see 1 Sam 8).
Therefore, if Isaac and Samuel had been among those chosen for the priesthood, Isaac on account of Esau and Samuel on account of his children would have had to be counted unworthy of the priesthood.
But in such a case, since the sins of parents are not imputed to children, should we not set the sins of children as a prior condemnation against parents?
How, then, shall we judge? First, it must be said that the name of the priesthood is so holy that, even if by our own deeds we are not unworthy of the episcopate, we should not be admitted to this rank because of the disorderliness of our children.
For with what freedom can we rebuke the sons of others and teach them right paths, when the one rebuked can answer us: first teach your own?
Or with what face shall I reproach a fornicator when my own conscience says to me in reply: then disinherit your fornicating son, and reject your children who give themselves to vices?
But when an unworthy son lives under the same roof with you, then by acting so, that is, by rebuking the sons of others, are you not removing the speck from another's eye while not seeing the beam in your own?
Thus the Apostle's words do not defile the righteous man because of his children's vices. They guard freedom of speech for the presider of the Church.
He should be such that he does not fear to rebuke the children of others because of the viciousness of his own."
