"I am sending him, who is my very heart, back to you. I would have liked to keep him with me so that he could take your place in helping me while I am in chains for the gospel." (Philemon 1:12-13)
Philemon is the shortest of Paul's letters, twenty-five verses, and the most purely personal. It is addressed to Philemon, a wealthy Christian householder in Colossae, concerning his runaway slave Onesimus who had encountered Paul in prison and become a Christian. Paul is returning Onesimus to his master, accompanied by this letter which is a masterpiece of pastoral diplomacy and Christian social reasoning. Paul begins with lavish thanksgiving for Philemon's faith and love, his refreshing of the saints, and builds a relationship of warmth and mutual obligation before making his request.
He could command Philemon to do what is required, but instead appeals on the basis of love. Onesimus, whom Paul has fathered in the faith while in chains, is now dear to Paul as his very heart. I am sending him, who is my very heart, back to you. I would have liked to keep him with me so that he could take your place in helping me while I am in chains for the gospel. But Paul does not want to do anything without Philemon's consent so that any favour he does will be spontaneous and not forced. He asks Philemon to receive Onesimus no longer as a slave but better than a slave, as a dear brother in the Lord. If he has wronged Philemon or owes him anything, Paul will repay it. He is confident Philemon will do even more than he asks.
The letter never explicitly calls for the abolition of slavery. But the logic it deploys is more revolutionary than any explicit command: if Onesimus is now a dear brother in Christ, the category of slave has been fundamentally destabilised. The Catechism draws on this logic in its teaching on human dignity: the Gospel does not immediately overthrow social structures but introduces into them a new reality that over time transforms them from within (CCC 1938). The Church's long engagement with the question of slavery shows both the slowness of this transformation and its ultimate power.
Brothers and sisters, Paul asks Philemon to receive Onesimus as he would receive Paul himself. This is the logic of Christian community applied to the hardest case: the person who has wronged you, who owes you something, who belongs to a lower social category, is to be received as a dear brother because he belongs to the same Lord. Who is your Onesimus? Who is the person you need to receive not as they have been to you but as who they now are in Christ?
Lord God, you receive us not as what we were but as what we are in Christ: dear brothers and sisters, co-heirs of the same Kingdom. Give us Paul's courage to intercede for those who have wronged others, and Philemon's generosity to receive them as brothers. Let the Gospel transform every relationship from within. Through Christ our Lord. Amen.
