John IV, Pope of Rome
John IV, (d. 642) a Dalmatian by birth, was the son of Venetius, whom
scholars believe to have been a Byzantine official in Ravenna. John was an
archdeacon at the time of his election to the papacy (640), and as pope,
he condemned Pelagianism and monothelitism. He also condemned the Celtic
church's practice in calculating the date of Easter. John defended
Honorius I's interpretation of the wills of Christ in a letter to Emperor
Constantine III because John believed that the clergy in Rome and in
Constantinople had failed to understand Honorius' reasoning properly.
