Epiphanius of Constantinople was a 6th-century prelate who served as the Ecumenical Patriarch of Constantinople from 520 until his death in 535. A supporter of Chalcedonian Christianity, he was elected to the position by Emperor Justin I with the support of the clergy and the public. Before his elevation, he managed the affairs of catechumens and assisted in collecting documents to facilitate reunification with the Roman Church. His leadership was characterized by efforts to maintain theological unity and peace between the Eastern and Western churches.
