II. In the next verse, the essential purpose for which the whole letter was written is put at last in an articulate request, based upon a very tender motive. "If then thou countest me as a partner, receive him as myself," Paul now at last completes the sentence which he began in _v_. 12, and from which he was hurried away by the other thoughts that came crowding in upon him. This plea for the kindly welcome to be accorded to Onesimus has been knocking at the door of his lips for utterance from the beginning of the letter; but only now, so near the end, after so much conciliation, he ventures to put it into plain words; and even now he does not dwell on it, but goes quickly on to another point. He puts his requests on a modest and yet a strong ground, appealing to Philemon's sense of comradeship--"if thou countest me a partner"--a comrade or a sharer in Christian blessings. He sinks all reference to apostolic authority, and only points to their common possession of faith, hope, and joy in Christ. "Receive him as myself." That request was sufficiently illustrated in the preceding chapter, so that I need only refer to what was then said on this instance of interceding love identifying itself with its object, and on the enunciation in it of great Christian truth.
III. The course of thought next shows--Love taking the slave's debts on itself.
"If he hath wronged thee, or oweth thee aught." Paul makes an "if" of what he knew well enough to be the fact; for no doubt Onesimus had told him all his faults, and the whole context shows that there was no uncertainty in Paul's mind, but that he puts the wrong hypothetically for the same reason for which he chooses to say, "was parted" instead of "ran away," namely, to keep some thin veil over the crimes of a penitent, and not to rasp him with rough words. For the same reason, too, he falls back upon the gentler expressions, "wronged" and "oweth," instead of blurting out the ugly word "stolen." And then, with a half-playful assumption of lawyer-like phraseology, he bids Philemon put that to his account. Here is my autograph--"I Paul write it with mine own hand"--I make this letter into a bond. Witness my hand; "I will repay it." The formal tone of the promise, rendered more formal by the insertion of the name--and perhaps by that sentence only being in his own handwriting--seems to warrant the explanation that it is half playful; for he could never have supposed that Philemon would exact the fulfilment of the bond, and we have no reason to suppose that, if he had, Paul could really have paid the amount. But beneath the playfulness there lies the implied exhortation to forgive the money wrong as well as the others which Onesimus had done him.
The verb used here for _put to the account of_ is, according to the commentators, a very rare word; and perhaps the singular phrase may be chosen to let another great Christian truth shine through. Was Paul's love the only one that we know of which took the slave's debts on itself? Did anybody else ever say, "Put that on mine account"? We have been taught to ask for the forgiveness of our sins as "debts," and we have been taught that there is One on whom God has made to meet the iniquities of us all. Christ takes on Himself all Paul's debt, all Philemon's, all ours. He has paid the ransom for all, and He so identifies Himself with men that He takes all their sins upon Him, and so identifies men with Himself that they are "received as Himself." It is His great example that Paul is trying to copy here. Forgiven all that great debt, he dare not rise from his knees to take his brother by the throat, but goes forth to show to his fellow the mercy which he has found, and to model his life after the pattern of that miracle of love in which is his trust. It is Christ's own voice which echoes in "put that on mine account."
