John IV (surnamed
Jejunator, sometimes also
Cappadox) was born at
Constantinople of artisan parents, and worked as a goldsmith. Under the Patriarch
John Scholasticus (565–577) he was deacon at the
Hagia Sophia church; then he became
sakellarios (an official who acts as patriarchal vicar for monasteries). He was famous for his ascetical life and called "the Faster". Under
Eutychius of Constantinople (552–565 and 577–582) he became an important person among the clergy of the city. At Eutychius's death he was made patriarch by the Emperor
Tiberius II Constantine (574–582). According to one account, a horse show was scheduled in the Hippodrome on eve of the
Feast of Pentecost. Patriarch John IV found his flock's attendance unacceptable. Through the patriarch's fervent prayer, a terrible thunderstorm arose with rain and hailstones so that everyone dispersed in fear and came to realize the inappropriateness of such entertainment. In 587 or 588, he summoned the bishops of the East in the name of the "
Ecumenical Patriarch" to examine certain charges against
Gregory of Antioch,
Patriarch of Antioch, (although Fortescue questions on what authority). Patriarch Gregory was acquitted and returned to his
episcopal see. A report was sent to Rome and
Pope Pelagius II solemnly annulled the acts of this council. In 590 Pope Pelagius II was succeeded by
Pope Gregory I, who was initially on good terms with John IV, whom he had known when Gregory I served as legate at Constantinople. In 593, John IV was severely blamed by Pope Gregory I for having allowed an
Isaurian
presbyter named Anastasius, who had been accused of heresy, to be beaten with ropes in the church of Constantinople. In 595, the controversy was again rife about the title of Ecumenical Patriarch. Gregory wrote to his legate Sabinianus forbidding him to communicate with John IV. In the case of a presbyter named Athanasius, accused of being to some extent a
Manichaean, and condemned as such, Gregory I tried to show that the accuser was himself a
Pelagian, and that by the carelessness, ignorance, or fault of John IV, the Nestorian council of Ephesus had actually been mistaken for the Orthodox
Council of Ephesus. == Works ==
