Translation of the relics of Venerable Theodore, Abbot of Studion
Today the Church commemorates the transfer of the sacred relics of Saint Theodore of Studion (November 11) from the island of Prinkēpo to Studion Monastery, which occurred in the year 844 (or 845), under Patriarch Methodios of Constantinople (842 - 846). The holy Confessor's relics were preserved whole and incorrupt, to such an extent that even his skin did not undergo the slightest change.
In addition to the relics of Saint Theodore, those of his exiled brother, Saint Joseph, the Bishop of Thessaloniki (July 4), who also suffered at the hands of the iconoclasts, were taken to Constantinople. The holy relics of both brothers were placed beside the coffin of their Igoumen and uncle Saint Platon (April 5).1
1 Saint Platon is commemorated on April 4 in Greek usage.
