Dictionary of Christian Biography and Literature to the End of the Sixth Century/Dorotheus (7), bp. of Martianopolis

Dorotheus (7), bp. of Martianopolis in Moesia Secunda, and metropolitan; a zealous supporter of the doctrines of Nesturios, and a determined enemy of the title θεοτόκος. Preaching in Constantinople not long before the council of Ephesus, he declared that "if any one asserted that Mary was the mother of God he was anathema" (Ep. Cyrill. ap. Baluz. Concil. col. 402). He attended that council, a.d. 431, signing the appeal to the emperor against the dominant party (Baluz. 701), and joining in the documents warning the clergy and people of Hierapolis and Constantinople against the errors of Cyril, and announcing Cyril's excommunication (ib. 706, 725). He was deposed and excommunicated by Cyril and his friends. This deposition being confirmed by the imperial power, he was ordered by Maximinian's synod at Constantinople to be ejected from his city and throne. His influence, however, with his people was so great that they refused to receive his successor Secundianus, and drove him from the city (Ep. Doroth. ad Cyrill. Baluz. 750), whereupon Dorotheus was banished by the emperor to Caesarea in Cappadocia. Two letters of his to John of Antioch are preserved in the Synodicon (Nos. 78, 115; Baluz. 781, 816), expressing his anxiety at Paul's setting out to Egypt and his distress at hearing that terms had been come to with Cyril, and a third (No. 137; Baluz. 840) to Alexander of Hierapolis and Theodoret, proposing a joint appeal to the emperor.
