Venerable Theocteristus, Abbot of Symbola on Mount Olympus, Bithynia
Saint Theosteriktos (Θεοστήρικτος) was the Igoumen of Symbola Monastery on Mount Olympus in Bithynia (others say Peletiki Monastery at Triglia). He lived during the reign of Constantine V Copronymos (741-755), who persecuted the Orthodox because they venerated icons.
On Holy Thursday, the governor, Michael Lachonodrakon attacked Theosteriktos’s monastery. Thirty-eight monks were placed under arrest, while others were tortured and mutilated. Igoumen Theosteriktos had his nose cut off, and he was put in jail in Constantinople with Saint Stephen the Younger (November 28) and many others.
When the iconoclastic persecution had ceased, Saint Theosteriktos returned to his monastery, which he rebuilt with the help of Saint Nikḗtas of Medikion (April 3).
Saint Theosteriktos reposed in peace. He is also commemorated on February 17.
