Very wisely the apostle undertakes the matter, reminding him of his benefactions to others, in order to soften him all the more, while he considers that if he gives to others, to strangers, then all the more he ought to do this for Paul, his teacher. And he did not simply say: "you give to the saints," but you refresh "the hearts of the saints," that is, that they wholeheartedly receive your kindness, as it is offered to them generously and with comforting hospitality.
Philem. 1:8–9. Therefore, though I have great boldness in Christ to command you what is proper, for love's sake I rather beseech,
Since, he says, you are such toward all the saints, that their hearts are refreshed by you, all the more I in Christ, that is, as having begotten you in Christ, I had boldness to command you, not as your master, but out of the love which I have for you and you for me. "That which is fitting," either — he commands you what is fitting, that is, that you fulfill what I need; or — that you honor all the saints: therefore I also, in accordance with what is fitting, that is, what falls to my lot, I had boldness to command you, yet I beseech. For I have such a necessary matter as to entreat you.
Philem. 1:9. Not another, but I myself, Paul the aged, and now also a prisoner of Jesus Christ;
Being such an ambassador, he says, I am worthy of being heard, as befits Paul the aged, that is, one who has authority both by virtue of his teaching dignity and by his age, and who has now received yet another, more important distinction — namely, being in chains for Christ. Do you see how many grounds for persuasion there are?
Philem. 1:10–11. I beseech thee for my son Onesimus, whom I have begotten in my bonds.
He has not yet mentioned the name of the one on whose behalf he is interceding. He first softens Philemon with praise of the servant, calling him his son. Why does he call him so? Because, he says, I begot him, that is, I instructed him with the Gospel and commanded that the one who believed be baptized, and this in difficult circumstances: in chains. Having thus softened his heart, he finally mentions the name.
Philem. 1:11. He was once useless to you
He knows that confession of sin extinguishes wrath; therefore he speaks thus.
Philem. 1:11. but now is useful both to you and to me; I am sending him back;
Since he became pious and holy, and therefore, he says, he is useful to both of us. If he is useful to Paul, who requires such great zeal, then certainly to Philemon as well. At the same time, he also implies that if he is useful to me, then he ought to be sent back to me. That is, I hand him over to you; use him as you wish. By handing him over, he all the more appeases his anger.
Philem. 1:12. But receive him as my own heart.
That is, receive him with love, or rather not him, but my very heart, for so much do I love him and carry him in my soul.
Philem. 1:13. I wished to keep him with myself, that on your behalf he might minister to me in my bonds for the gospel;
Pay attention to the wisdom of the apostle, how he gradually placed him (the servant) in the position of the master. "That in thy stead," he says, "he might minister unto me." He also shows that he desires the benefit of the master. If, he says, you are obligated to minister to me, and he does this in your stead, then clearly this is gain for you.
Philem. 1:14. But without your consent I did not want to do anything,
And by this he softens Philemon most of all. The matter was so necessary: in chains, and moreover for God's sake, he intended to serve him; however, the apostle did not want to do this against Philemon's will. Therefore, should one not show mercy to him who could have made use of it himself, but did not want to?
Philem. 1:14. Not so that your good deed would be by compulsion, but voluntary.
He did not say: by necessity, but: "as it were by necessity," as if saying: of course, even by keeping him against your will, I would not truly have grieved you; nevertheless, to many it would have seemed that this was done by compulsion and against your will. Therefore now I preferred that this should in no case appear to anyone as forced, but, without doubt, voluntary.
Philem. 1:15. For perhaps he therefore departed for a time,
Since Onesimus ran away with evil intent, Paul turns this flight into something beneficial. Perhaps, he says, he ran away by the providence of God. He also commendably calls the flight a separation, so as not to irritate the master with the word "flight." And by shortening the time, he calms his anger. "For an hour," he says, "he was separated." At the same time he also shows that however long he was with Paul, he was also with Philemon. Therefore he was absent only for the time he spent before meeting Paul; and this is an insignificant amount of time, as if a single hour. Therefore from now on, if he, having been released by you, remains with me, then understand that he is serving you.
Philem. 1:15. To receive him back forever,
You will make use of it.
Philem. 1:16. No longer as a slave, but above a slave, as a beloved brother, especially to me, and how much more to you, both in the flesh and in the Lord.
Much, he says, benefit the flight brought: instead of one hour, you have him forever. For even the whole life of a man, in comparison with eternity, is nothing; much more so the time of flight. So instead of a slave, receive a brother; instead of an unprofitable one — a beloved one; "both in the flesh," that is, even in worldly matters he is worthy of love, as one who is serviceable, "and in the Lord," that is, in spiritual matters.
