Introduction to Onesimus

Onesimus is a significant yet often overlooked figure in the New Testament, particularly known from Paul’s letter to Philemon. The name “Onesimus” means “useful” or “beneficial” in Greek, which becomes a play on words in Paul’s epistle. Onesimus was a runaway slave who encountered the Apostle Paul and became a Christian. His story is a powerful example of transformation, reconciliation, and the early Christian view of social relationships, particularly regarding slavery and brotherhood in Christ.

Onesimus Pronunciation

“Onesimus” is pronounced as oh-NESS-ih-muss, with the primary stress on the second syllable.

Onesimus in the New Testament

Onesimus appears most prominently in the following New Testament books:

• Philemon: Onesimus is the central figure in Paul’s letter to Philemon. Paul writes to persuade Philemon, a Christian and slave owner, to accept Onesimus back—not just as a slave but as a beloved brother in Christ (Philemon 10–16).
• Colossians 4:9: Here, Paul refers to Onesimus as “our faithful and beloved brother, who is one of you,” indicating his standing among the Colossian Christians and showing he was entrusted with delivering Paul’s letters.

In the letter to Philemon, Paul intercedes on Onesimus’s behalf, using wordplay to emphasize his transformation: “Formerly he was useless to you, but now he has become useful both to you and to me” (Philemon 11). Paul even offers to repay any debt Onesimus owes, signaling a deep level of personal advocacy and care.
