Defense of the Icons
In 754 George attended the iconoclast Council of Hieria, convened in Constantinople, which banned the veneration of icons. As an iconodule he refused to comply with the rulings of the council, and for this he was exiled by the Emperor Constantine V.
He afterward returned from exile and took part in the restoration of the veneration of the holy images at the Second Council of Nicaea in 787, the council that affirmed the Orthodox doctrine of the icons.
When iconoclasm was renewed at the onset of the reign of the Emperor Leo V, George again opposed it, refusing to remove the icons from the churches within his diocese. For this renewed confession he was banished a second time, and he died in exile in 814. For his steadfastness throughout the iconoclast controversy he is named a confessor of the faith.
