He was a Phrygian by birth, a slave of Philemon, to whom the Apostle Paul addressed his epistle. Onesimos escaped from Philemon and fled to Rome, where he was converted to the Faith by St Paul. St Paul sent him back to his master, who at St Paul's urging gave him his freedom. He served the Church for many years before dying a martyr, beaten to death with clubs.   Saint Onesimos is also commemorated on November 22, with Sts Philemon, Archippus and Aphia; and on January 4 at the Synaxis of the Seventy Disciples.
