Philemon

To appeal to Philemon to receive Onesimus back - not just as a slave but as a dear brother in Christ - modeling how the gospel transforms the most fundamental social relationships.

Paul's shortest letter intercedes for the runaway slave Onesimus, asking his owner Philemon to receive him back — not as a slave but as a dear brother — in the most personalised application of gospel reconciliation in the New Testament.

Philemon is the New Testament's most concrete application of gospel reconciliation to a specific social relationship — and the seed of the church's eventual challenge to slavery.
