Venerable Theodore the Confessor, Abbot of the Studion monastery and defender of the holy icons.
Saint Theodore was born in Constantinople in 759 and became abbot of the monastery of the Studion, which he made a model of monastic order. He suffered repeated exile and imprisonment, first for opposing the uncanonical marriage of the emperor and later for defending the veneration of the holy icons.
He wrote extensively on the monastic life and the icons, composed many hymns, and reposed in exile in 826.
