- The Epistle to Philemon is a Pauline epistle of the New Testament of the Christian Bible. It is a prison letter, authored by Paul the Apostle (the opening verse also mentions Timothy), to Philemon, a leader in the Colossian church. Paul does not identify himself as an apostle with authority, but as “a prisoner of Jesus Christ”, calling Timothy “our brother”, and addressing Philemon as “fellow labourer” and “brother” (Philemon 1:1; 1:7; 1:20). Onesimus, a slave who had escaped from his master Philemon, was returning with this epistle wherein Paul asked Philemon to receive him as a “brother beloved” (Philemon 1:9–17). The letter appeals on behalf of Onesimus, who subsequently became a Christian through Paul. Paul requests that Philemon receive Onesimus not as a slave but as a beloved brother in Christ, offering to repay any debt Onesimus owes.
