Philemon and Onesimus: Paul’s shortest letter and a runaway slave sent home as a brother

It is only 25 verses long, but it carries a request that must have been hard to hear. Paul, writing from prison, asked a wealthy believer named Philemon to take back Onesimus, a slave who had run away from him. Onesimus had met Paul, become a Christian and was now being sent home. Paul asked Philemon to receive him as a brother.

Philemon, Onesimus and Paul's appeal

Philemon was a Christian in Colossae, in present-day Turkey. A church met in his home. Paul calls him a “dear friend and fellow worker”. Onesimus was a slave in Philemon’s household who ran away, possibly after stealing money. He somehow came into contact with Paul, who was in prison, and became a believer. The name Onesimus means “useful”. Paul writes: “Formerly he was useless to you, but now he has become useful both to you and to me” (Philemon 11).

Paul could have ordered Philemon to forgive Onesimus but chose to appeal “on the basis of love”. He described Onesimus as “my son” and “my very heart”.

More than a slave

The key verse asks Philemon to welcome Onesimus “no longer as a slave, but better than a slave, as a dear brother” (verse 16). The gospel changed the relationship between master and slave. Paul offered to cover any loss: “If he has done you any wrong or owes you anything, charge it to me.” Many readers see a picture of Christ taking on the debt of sinners.

The letter does not directly command the end of slavery, and some people used Scripture to defend slavery for centuries. Others, including abolitionists, argued that letters like Philemon undermined slavery by treating slaves as equal brothers and sisters in Christ.

What happened next and reconciliation

The Bible does not say how Philemon responded. Early church tradition suggests that an Onesimus later became a bishop in Ephesus, though it is not certain he was the same man. Philemon shows how faith reshapes relationships. Forgiveness and reconciliation can be costly, and they often need someone to stand in the middle, as Paul did.

Is there someone you need to welcome back, or someone you need to help reconcile with another person? Ask God for the courage to take the first step.
