Patriarch Gennadius I of Constantinople

Saint Gennadius (Greek: Άγιος Γεννάδιος) was the 21st Ecumenical Patriarch of Constantinople (d. 25 August 471). Gennadius is seen to have been a learned writer and followed the Antiochene school of literal exegesis, although few writings have been left about him. He is celebrated in the Greek Orthodox Church on November 17, but is not listed in the Roman Martyrology.

His first public writing was quoted by Facundus (Defensio, II, iv) against Saint Cyril of Alexandria in two works, probably in 431 or 432, including a passage to show that his work was more violent even than the letter of Ibas. The Anathemas of Cyril and Two Books to Parthenius were criticized. In the latter he exclaims, "How many times have I heard blasphemies from Cyril of Egypt? Woe to the scourge of Alexandria!". In 433 Gennadius probably reconciled with Cyril. If Saint Cyril's letter of 434 (Ep. lvi) is to the same Gennadius, they were friends in that year. Gennadius was a presbyter at Constantinople when he succeeded Anatolius in 458 as the Bishop of Constantinople. From the beginning of his episcopate Gennadius proved his zeal for the Christian faith and the maintenance of discipline. His discretion was before long tested.

Timothy Aelurus, the Monophysite who made himself the Patriarch of Alexandria and was later chased from the Patriarchate by order of the Roman emperor, had obtained leave to come to Constantinople, intending to re-establish himself on his throne. On June 17, 460, Pope Leo I warned Gennadius (Ep. clxx) against Timothy Aelurus, and urged him to prevent the voyage of Timothy and to secure the immediate consecration of an Orthodox Patriarch for Alexandria. Timothy Aelurus was banished to the Chersonese, and Timothy Solofaciolus was chosen bishop of Alexandria in his stead. About the same time, Gennadius' liberality and desire for order was observed in his appointment of Marcian, a Novatianist who had come over to the Orthodox church, the oeconomus of the goods of the church of Constantinople.
