A prisoner of Christ Jesus] Paul thus describes himself because his bonds (which are to be here understood literally) have been incurred in the service of Christ: cp. Philemon 1:9 (and Philemon 1:23) and Ephesians 3:1; Ephesians 4:1. The usual claim to be an Apostle is here unnecessary; so Philippians 1:1, in that Epistle of Paul which stands next to Philemon in its tender intimacy.
Timothy] with Paul in Ephesus (Acts 19:22), and doubtless known to Philemon: cp. Philippians 1:1; Philippians 2:19; Colossians 1:1. Our brother] 'my fellow-Christian': cp. 1 Corinthians 5:11, also 2 Corinthians 1:1; Colossians 1:1; 1 Thessalonians 3:2. So Philemon 1:2, 'sister'; cp. Romans 16:1. Beloved] as in the English epistolary 'My dear.' Here probably with a certain emphasis: cp. 3 John 1:1.
Fellowlabourer] RV 'fellow-worker': i.e. in the gospel: cp. Philemon 1:2; Philemon 1:24; Romans 16:3; 2 Corinthians 8:23; Philippians 2:25, etc.
Recipients and Occasion. Philemon was a resident of Colossae in Phrygia (cp. Colossians 4:9 with Philemon 1:11). He owed his conversion to Paul (Philemon 1:19), having perhaps heard the gospel on some visit to Ephesus during the three years of Paul's stay there (Acts 19). A man of wealth, he had distinguished himself by deeds of charity (Philemon 1:5), as well as by zeal in spreading the gospel (Philemon 1:1), and his house was the habitual meeting-place of a group of Colossian Christians (Philemon 1:2). He may be compared with Stephanas of Corinth (1 Corinthians 16:15). Apphia (Philemon 1:2), also a Christian, bearing a characteristic native Phrygian name, was doubtless Philemon's wife, and the subject of the letter concerned her too. Archippus may have been their son. He had a 'ministry' (perhaps as presbyter or evangelist) at Laodicea (Colossians 4:15). Onesimus (a name often borne by Greek slaves at this period) was a slave (doubtless a house-slave) of Philemon, who had run away, probably robbing his master at the same time. Reaching Rome (or, according to some, Csesarea), he had somehow found his master's friend Paul. Such a chance would not be surprising in a great and compactly populated city. In his desperate case, liable to arrest and the severest punishment, he may have voluntarily sought the Apostle's aid. At any rate he met with kindness, was brought to faith in Christ, and served Paul with grateful devotion. When Tychicus went to Asia Minor (Colossians 4:7), Paul took the occasion to send back Onesimus, now 'the faithful and beloved brother,' with general commendation to the Colossian Christians, and with this special letter of intercession to Philemon.
The letter was thus written in the same circumstances, and sent at the same time, as Colossians (cp. Colossians 4:9 with Philemon 1:12; Philemon 1:17): see, however. Colossians 4:10, and on Philemon 1:23. The place of writing was probably Rome, where Paul was imprisoned. The escaped slave may well have tried to lose himself in the throngs of the capital, and would have been at least as well able to secure transportation thither as to Cassarea.
