(); Boniface III had an important relationship with him. The son of Iohannes (John) Cataadioce, Boniface was of
Roman extraction. While serving as a
deacon, Boniface impressed
Pope Gregory I, who described him as a man "of tried faith and character" and selected him to be
papal apocrisiarius to the imperial court in
Constantinople in 603. This was to be a significant time in his life and helped to shape his short but eventful papacy. As
apocrisarius, Boniface had the ear of Emperor
Phocas and was held in esteem by him. This proved important when he was instructed by Pope Gregory to intercede with Emperor Phocas on behalf of Bishop Alcison of Cassiope on the island of
Corcyra. Alcison found his episcopate being usurped by
Bishop John of Euria in
Epirus, who had fled his home along with his clergy to escape from attacks by the
Slavs and
Avars. John, having found himself safe on Corcyra, was not content to serve under Bishop Alcison; instead he set about trying to usurp his episcopal authority. Normally, this behaviour would not have been tolerated, but Emperor Phocas was sympathetic to Bishop John and not inclined to interfere. Alcison appealed to Pope Gregory, who left the problem to Boniface to resolve. In a stroke of diplomatic genius, Boniface managed to reconcile all the parties while still retaining the confidence of the emperor. ==Papacy==
