Onesimus is a lesser-known name in the Bible, but his story carries a powerful message of redemption, forgiveness, and transformation. Found mainly in the book of Philemon, Onesimus went from being a runaway slave to a beloved brother in Christ. Here are 10 interesting facts about him, supported with Bible verses.
1. Onesimus Was a Slave
Onesimus served Philemon, a Christian living in Colossae. In Paul’s letter to Philemon, he is described as a bondservant. His name means “useful,” but Paul makes a wordplay, calling him formerly "useless."
“Formerly he was useless to you, but now he has become useful both to you and to me.” — Philemon 1:11
2. He Ran Away From His Master
Onesimus fled from Philemon, possibly stealing from him before doing so. This was a serious offense under Roman law and could have resulted in severe punishment or death.
“If he has done you any wrong or owes you anything, charge it to me.” — Philemon 1:18
3. He Met Paul in Prison
After running away, Onesimus crossed paths with the Apostle Paul, who was imprisoned at the time. Through Paul, Onesimus heard the gospel and gave his life to Christ.
“I appeal to you for my son Onesimus, who became my son while I was in chains.” — Philemon 1:10
4. Paul Considered Him a Spiritual Son
Paul didn't just convert Onesimus; he nurtured him in the faith. He called Onesimus his “son,” showing deep affection and spiritual responsibility for him.
“Who became my son while I was in chains.” — Philemon 1:10
5. He Was a Changed Man
After his conversion, Onesimus became faithful and dependable. He was no longer just a runaway slave—he was a brother in Christ and a trusted helper to Paul.
“He is very dear to me but even dearer to you, both as a fellow man and as a brother in the Lord.” — Philemon 1:16
6. Paul Sent Him Back With a Letter
Paul didn’t keep Onesimus with him, even though he wanted to. Instead, he sent him back to Philemon, not as a slave but as a brother, carrying the very letter that would become the book of Philemon.
“I am sending him—who is my very heart—back to you.” — Philemon 1:12
7. Paul Asked Philemon to Forgive Him
Paul pleaded with Philemon to accept Onesimus with grace, just as he would welcome Paul himself. He didn’t force the issue but appealed in love.
“If you consider me a partner, welcome him as you would welcome me.” — Philemon 1:17
8. He Is Mentioned in Colossians
Onesimus also appears in Paul’s letter to the Colossians. By that time, he was trusted enough to carry messages to the church alongside Tychicus.
“He is coming with Onesimus, our faithful and dear brother, who is one of you.” — Colossians 4:9
9. He May Have Become a Church Leader
According to early church tradition, Onesimus later became a bishop of Ephesus. While this isn’t stated in Scripture, it shows how his transformation left a lasting legacy in the church.
10. His Story Reflects the Gospel
The story of Onesimus mirrors our story in Christ. We were once far off, enslaved to sin, but through Jesus, we are restored, forgiven, and made useful in God’s kingdom.
“So you are no longer a slave, but God’s child; and since you are his child, God has made you also an heir.” — Galatians 4:7
