Dictionary of Christian Biography and Literature to the End of the Sixth Century/Theosebas, a deacon
Theosebas, a deacon of the Thirian (? Tyrian) church, ordained priest by bp. John of Jerusalem. Jerome takes this ordination as a justification of the ordination of his brother Paulinian by Epiphanius, bp. of Salamis. He describes Theosebas as an eloquent man, and believes John to have ordained him in order to employ him to speak against himself and his friends (Hieron. Cont. Joan. Hierosol. 41).
