Gregory Thaumaturgus
Being early placed at the head of an ecclesiastical province, Neocæsarea had four suffragan sees about 640 ("Ecthesis" of pseudo-Epiphanius, ed. Heinrich Gelzer, 539), retaining them until the tenth century, when Trebizond obtained its independence and, by degrees, the other three suffragans were suppressed. In 1391 the Archdiocese of Neocaesarea was confided to the metropolitan of Trebizond (Miklosich and Müller, "Acta", II, 154). About 1400 there was, however, a regular metropolitan (op. cit., II, 312), residing at Ordu. Among the twenty-seven bishops of this city mentioned by Le Quien, the most noted are Saints Gregory Thaumaturgus, Paul of Neocaesarea, and Thomas, a 9th-century martyr.
