Patriarch of Constantinople from 449 to 458. Known for his simple, austere life, his charity to the poor, his zeal for the faith, and his opposition to heresy. He opposed the heretic Dioscurus at the Council of Chalcedon, and supported the doctrinal authority of Pope Saint Leo the Great, which put him in the midst of both theological and political turmoil. He fought against the Nestorian heresy at the Council of Ephesus. Miraculously healed from a serious illness by Saint Daniel the Stylite. May have been murdered by local heretics for his support of the Pope. Some of his writings, correspondence and hymns have survived the centuries.
