Nothing is known of Philemon beyond what is found in this epistle, nor is it clear where he resided. The similarity of the salutations to those found in the Epistle to the Colossians, and the reference to Onesimus in that epistle, leads to the conclusion that Philemon dwelt somewhere in the direction of Colosse (probably at Laodicea, Archippus being mentioned in Colossians 4:17 and Philemon 1:1-2), and that both epistles were sent from Rome about A.D. 62. Though the assembly in the house of Philemon is mentioned in Philemon 1:2, the epistle is a personal one to Philemon and his wife.
Onesimus their slave had run away, and, having been converted under the ministry of Paul, he was sent back by the latter to his master. Paul does not ask for the freedom of Onesimus, but that he may now be received in grace as a brother, indeed, he received as the apostle’s “own bowels.” Paul does not assert apostolic authority, but entreats as the “prisoner” and “the aged.” Led by the Holy Spirit, the epistle is a gracious appeal, and difficulties are met in it in a matter requiring much delicacy. If the slave had robbed Philemon, Paul would repay it; but he reminds Philemon of how much he owed him, even his “own self besides.”
Some may be surprised that such an epistle should form part of the inspired word. But it is “profitable”; for fifteen hundred years slaves were extensively owned by Christians. Many may never have thought of seeking their conversion, or may have been prejudiced against it. A Boer in South Africa, though a Christian himself, once told a preacher that he was sure he might as well preach to the dogs as to his African servants. God saw the need of such an epistle. The slave had become “ a brother beloved.”
