Chalcedon
Chalcedon ( or ;
, sometimes transliterated as "Chalkedon") was an ancient maritime town of Bithynia, in Asia Minor. It was located almost directly opposite Byzantium, south of Scutari (modern Üsküdar) and it is now a district of the city of Istanbul named Kadıköy. The name "Chalcedon" is a variant of Calchedon, found on all the coins of the town as well as in manuscripts of Herodotus's "Histories", Xenophon's "Hellenica", Arrian's "Anabasis", and other works. Except for a tower, almost no above-ground vestiges of the ancient city survive in Kadıköy today; artifacts uncovered at Altıyol and other excavation sites are on display at the Istanbul Archaeological Museum.
Council of Chalcedon
Justinian I attempted to bring those monks who still rejected the decision of the Council of Chalcedon into communion with the greater church. The exact time of this event is unknown, but it is believed to have been between 535 and 548. St Abraham of Farshut was summoned to Constantinople and he chose to bring with him four monks. Upon arrival, Justinian summoned them and informed them that they would either accept the decision of the council or lose their positions. Abraham refused to entertain the idea. Theodora tried to persuade Justinian to change his mind, seemingly to no avail. Abraham himself stated in a letter to his monks that he preferred to remain in exile rather than subscribe to a faith contrary to that of Athanasius. They were not alone, and the non-Chalcedon churches compose Oriental Orthodoxy, with the Church of Alexandria as their primus inter pares. Only in recent years has a degree of rapprochement between Chalcedonian Christians and the Oriental Orthodox been seen.
