Onesimus (Greek: Ὀνήσιμος, translit. Onēsimos, meaning "useful"; died c. 68 AD, according to Catholic tradition),[1] also called Onesimus of Byzantium and The Holy Apostle Onesimus in the Eastern Orthodox Church,[2] was probably a slave[3] to Philemon of Colossae, a man of Christian faith. He may also be the same Onesimus named by Ignatius of Antioch (died c. 107) as bishop in Ephesus[4] which would put Onesimus's death closer to 95. If so, Onesimus went from slave to brother to bishop.
