Iconoclasm and confession
George's title of Confessor derives from his steadfast defense of the veneration of icons during the Byzantine iconoclast controversy. The sources record that he refused to follow the wishes of the iconoclast authorities and openly upheld icon veneration, for which he was deposed and exiled rather than martyred — the distinction that the Church marks with the rank of Confessor.
The synaxarion accounts associate his confession with the renewed iconoclasm under Leo the Armenian, when he was banished to Cherson and died in exile.
Some hagiographic notices additionally connect his sufferings to an earlier period of iconoclast persecution; the surviving accounts are not fully consistent on the chronology, and the dataset places him firmly in the 9th century and the Byzantine era.
