Onesimus, also called Onesimus of Byzantium and The Holy Apostle Onesimus in the Eastern Orthodox Church, was a slave to Philemon of Colossae, a man of Christian faith. He may also be the same Onesimus named by Ignatius of Antioch as bishop in Ephesus which would put Onesimus's death closer to 107. If so, Onesimus went from slave to brother to bishop.
