The structure of the letter is of the utmost simplicity. It is not so much a structure as a flow. There is the usual superscription and salutation, followed, according to Paul's custom, by the expression of his thankful recognition of the love and faith of Philemon and his prayer for the perfecting of these. Then he goes straight to the business in hand, and with incomparable persuasiveness pleads for a welcome to Onesimus, bringing all possible reasons to converge on that one request, with an ingenious eloquence born of earnestness. Having poured out his heart in this pleasure adds no more but affectionate greetings from his companions and himself.
In the present section we shall confine our attention to the superscription and opening salutation.
I. We may observe the Apostle's designation of himself, as marked by consummate and instinctive appreciation of the claims of friendship, and of his own position in this letter as a suppliant. He does not come to his friend clothed with apostolic authority. In his letters to the Churches he always puts that in the forefront, and when he expected to be met by opponents, as in Galatia, there is a certain ring of defiance in his claim to receive his commission through no human intervention, but straight from heaven. Sometimes, as in the Epistle to the Colossians, he unites another strangely contrasted title, and calls himself also "the slave" of Christ; the one name asserting authority, the other bowing in humility before his Owner and Master. But here he is writing as a friend to a friend, and his object is to win his friend to a piece of Christian conduct which may be somewhat against the grain. Apostolic authority will not go half so far as personal influence in this case. So he drops all reference to it, and, instead, lets Philemon hear the fetters jangling on his limbs--a more powerful plea. "Paul, a prisoner," surely that would go straight to Philemon's heart, and give all but irresistible force to the request which follows. Surely if he could do anything to show his love and gratify even momentarily his friend in prison, he would not refuse it. If this designation had been calculated to produce effect, it would have lost all its grace; but no one with any ear for the accents of inartificial spontaneousness, can fail to hear them in the unconscious pathos of these opening words, which say the right thing, all unaware of how right it is.
There is great dignity also, as well as profound faith, in the next words, in which the Apostle calls himself a prisoner "of Christ Jesus." With what calm ignoring of all subordinate agencies he looks to the true author of his captivity! Neither Jewish hatred nor Roman policy had shut him up in Rome. Christ Himself had riveted his manacles on his wrists, therefore he bore them as lightly and proudly as a bride might wear the bracelet that her husband had clasped on her arm. The expression reveals both the author of and the reason for his imprisonment, and discloses the conviction which held him up in it. He thinks of his Lord as the Lord of providence, whose hand moves the pieces on the board--Pharisees, and Roman governors, and guards, and Caesar; and he knows that he is an ambassador in bonds, for no crime, but for the testimony of Jesus. We need only notice that his younger companion Timothy is associated with the Apostle in the superscription, but disappears at once. The reason for the introduction of his name may either have been the slight additional weight thereby given to the request of the letter, or more probably, the additional authority thereby given to the junior, who would, in all likelihood, have much of Paul's work devolved on him when Paul was gone.
The names of the receivers of the letter bring before us a picture seen, as by one glimmering light across the centuries, of a Christian household in that Phrygian valley. The head of it, Philemon, appears to have been a native of, or at all events a resident in, Colossae; for Onesimus, his slave, is spoken of in the Epistle to the Church there as "one of _you_." He was a person of some standing and wealth, for he had a house large enough to admit of a "Church" assembling in it, and to accommodate the Apostle and his travelling companions if he should visit Colossae. He had apparently the means for large pecuniary help to poor brethren, and willingness to use them, for we read of the refreshment which his kindly deeds had imparted. He had been one of Paul's converts, and owed his own self to him; so that he must have met the Apostle,--who had probably not been in Colossae,--on some of his journeys, perhaps during his three years' residence in Ephesus. He was of mature years, if, as is probable, Archippus, who was old enough to have service to do in the Church (Col. iv. 17), was his son.
