Died December 10, 741. The son of a Syrian named John, he became a priest in Rome, and his reputation for learning and holiness was so great that he was acclaimed pope on February 11, 731, while accompanying the funeral cortege of his predecessor, Saint Gregory II.

He continued Gregory II’s opposition to iconoclasm and convoked two synods in Rome in 731, which condemned the heresy. In response, Emperor Leo the Iconoclast seized papal patrimonies in Calabria and Sicily and transferred ecclesiastical jurisdiction of those two provinces and Illyrium to the patriarch of Constantinople.

Gregory supported the missionary activities of Saint Boniface in Germany and sent Saint Willibald to assist him. Gregory completed rebuilding the walls around Rome begun by Gregory II and sought the assistance of Charles Martel against the attacks of Liutprand and his Lombards on the exarchate of Ravenna, the dukes of Spoleto and Benevento, and the duchy of Rome rather than from the Eastern Emperor, an appeal that was to have far-reaching historical implications for the meddling of the state in Church affairs, and by establishing a connection with the Franks. In the midst of this turmoil, Gregory died (Benedictines, Delaney).
