TEOGNIDE. — Bishop of Nicaea. An uncompromising Arian, he took part in the Council of Nicaea in 325.
Forced by circumstances, he subscribed to the Creed; but shortly afterwards, taking part in the heretics' intrigues to stir up trouble, he was deposed and banished to Gaul, and replaced in the see by Crestus. After three years he was recalled and reinstated in his Church, and together with Eusebius of Nicomedia, he led the opposition to the ὁμοούσιοι and to St. Athanasius. In 330 he took part in the Synod of Antioch at which Eustathius was deposed; in 335 he was at the Council of Tyre. He was a member of the mission sent to the Mareotis to gather evidence against St. Athanasius, and in 336 he helped to have the Saint driven into exile in Constantinople. After the death of Eusebius he became the recognized leader of Arianism, and in 341 he cooperated in the intrusion of Macedonius into the Church of Constantinople. He died shortly before 347.
