Ὀνήσιμος, Ὀνησίμου, (i. e. profitable, helpful; from ὄνησις profit), Onesimus, a Christian, the slave of Philemon: Philemon 1:10; Colossians 4:9. (Cf. Lightfoots Commentary, introduction, Hackett in B. D.)

Topical Lexicon
Name and Meaning

Onesimus (Ὀνήσιμος) bears a name that means “useful” or “profitable.” In the providence of God, this common slave name becomes a living parable as his life is transformed from unprofitable fugitive to profitable minister of the gospel.

Biblical Occurrences

Colossians 4:9 – “He is coming with Onesimus, our faithful and beloved brother, who is one of you. They will tell you about everything here.”
Philemon 1:10 – “I appeal to you for my child Onesimus, whose father I became while in chains.”

Historical Background: Slavery in the Roman World

First-century slavery was pervasive throughout the Roman Empire, encompassing household servants, field laborers, tradesmen, and professionals. A runaway slave faced harsh penalties, including branding or death. Against this backdrop, the gospel’s proclamation of equality in Christ (Galatians 3:28) carried radical implications, confronting entrenched social structures without fomenting revolution but transforming hearts and relationships from within.

Conversion and Discipleship

While Paul was imprisoned (likely in Rome), Onesimus fled from his master, Philemon of Colossae, and came into contact with the apostle. Under Paul’s evangelistic ministry, Onesimus was converted: “whose father I became while in chains” (Philemon 1:10). The spiritual rebirth changed his identity from a law-breaking bondservant to Paul’s “faithful and beloved brother” (Colossians 4:9). Paul’s choice of paternal language underscores discipleship: he not only preached to Onesimus but nurtured him in the faith (cf. 1 Corinthians 4:15).

Ministry Partnership with Paul

During Paul’s imprisonment Onesimus rendered valuable service. Philemon 1:13 suggests that the apostle found him “useful” (employing a play on his name) for ministering to his needs. Paul nevertheless chose the harder course—sending him back to his legal owner in company with Tychicus (Colossians 4:7-9). This action modeled obedience to civil law (Romans 13:1) while exemplifying trust in the reconciling power of the gospel.

Reconciliation and the New Family in Christ

Paul’s letter to Philemon is a masterclass in gospel-motivated reconciliation. The apostle appeals “for love’s sake” (Philemon 1:9), urging Philemon to receive Onesimus “no longer as a slave, but better than a slave, a beloved brother” (Philemon 1:16). The cross makes payment for every debt (Philemon 1:18-19), creating a fellowship that transcends social hierarchy (Colossians 3:11). Onesimus’s restitution exemplifies repentance; Philemon’s reception illustrates forgiveness; Paul’s mediation reflects Christ’s own intercession (Hebrews 7:25).

Theological Significance

1. Regeneration transforms social status into spiritual kinship.
2. Christian ethics call believers to voluntary, costly reconciliation.
3. The gospel operates within existing structures while sowing seeds that ultimately undermine injustice.
4. The narrative showcases apostolic authority harmonized with pastoral tenderness, illustrating how doctrine and love interweave.

Legacy in Church Tradition

Early Christian writers suggest that Onesimus later became a prominent leader, possibly the bishop of Ephesus mentioned by Ignatius of Antioch (Letter to the Ephesians 1.3). While not certain, the tradition reflects how the early Church viewed his story: an archetype of grace that lifts the lowly and equips them for oversight in God’s household.

Applications for Contemporary Believers

• No past failure places an individual beyond Christ’s redeeming reach.
• Spiritual parenthood—leading others to Christ and nurturing them—remains a vital calling.
• True reconciliation requires tangible steps of restitution and forgiveness.
• The Church is to embody a family ethos where earthly distinctions are secondary to unity in Christ.

Summary

Onesimus stands as a testimony to the power of the gospel to convert, reconcile, and commission. From runaway slave to beloved brother and co-laborer, his life proves that in Christ even the least can become profoundly “useful” for the advance of the kingdom.
