5. Bishop of MARTIANOPLE, lived about A. D. 431, and was a most obstinate follower of the party and heresies of Nestorius. He was so violent in his opinions, that shortly before the synod of Ephesus, he declared that any man who believed that the Virgin Mary was the mother of God was deserving of eternal damnation. He took part in the synod of Ephesus, which deposed him on account of his insisting upon the correctness of the Nestorian views; and a synod which was held soon after at Constantinople expelled him from his see. When Saturninus was appointed his successor, a popular tumult broke out at Martianople, in consequence of which Dorotheus was exiled by an imperial edict to Caesareia in Cappadocia.
