Tyana, Council Of (Concilium Tyanense)
was held in 367 in Tyana, a town of Asia Minor. There were present in this council Eusebius of Caesarea in Cappadocia, Athanasius of Ancyra, Pelagius of Laodicea, Gregory Nazianzen the elder, and many others who had declared their belief in the consubstantiality of the Son at Antioch in 363. The letters of pope Liberins and the bishops of Italy, Sicily, Africa, and Gaul were read, which had been written to wipe out the disgrace attaching to them on account of the Council of Ariminum. Eustathius of Sebaste, formerly deposed, was reestablished; and a synodical letter written to all the bishops of the East, exhorting them to testify in writing their rejection of the acts of Ariminum, and their adherence to the faith of Nicea. See Mansi, Concil. 2, 836.
