ST. JOHN the FASTER, PATRIARCH of CONSTANTINOPLE - September 2
Patriarch John IV is known for his set of penitential rules and as the first bishop of Constantinople to assume the title Ecumenical Patriarch (d. 595). He was born in Constantinople to artisan parents and was not well educated, but became famous for his exemplary ascetical life, which led to his being called "the Faster." He was a deacon before becoming the patriarchal vicar for monasteries. He became esteemed among the clergy of Constantinople at that time, and was named patriarch, John IV, by the emperor on April 11, 582.
In 588, Patriarch John IV convened a council in Constantinople to investigate charges against Patriarch Gregory of Antioch. The summons to the bishops of the East was done in the name of John IV as "Ecumenical Patriarch." While this title had been used as early as the reign of Acacius (471 to 489) in reference to the Patriarch of Constantinople, its use by John IV as a title in documents of his office was a first. (The title was used in the acts of the council, to which two popes of Rome later objected.) Within the Church, St. John is most noted as the compiler of a penitential nomokanon - a rule for penances. These rules are instructions for priests on how to hear confessions of secret sins that are either sins of commission or sins of intentions.
