Venerable Theoctistus, Abbot at Cucomo, in Sicily

Saint Theoktistos lived in the second half of the eighth century, during a period of widespread iconoclastic heresy. The Venerable One was the founder and Igoumen of Cucomo Monastery on the island of Sicily. During that difficult time for the Church, the Orthodox were persecuted by iconoclastic Emperors. Orthodox churches were closed, and the Holy Icons were desecrated and destroyed. The monks, in particular, were affected by the iconoclastic persecution because they protected the Holy Icons. The monks were expelled from their monasteries, which were destroyed, and they were forced to flee their homeland. Saint Theoktistos sheltered these Greek monks in his monastery.

The Seventh Ecumenical Council, which was convened in 787, condemned the iconoclast heresy, but even after that, the heresy, supported by iconoclastic Emperors, continued to disturb the peace of the Church. Only in the reign of the Holy Empress Theodora, at the Council of 842, was iconoclasm finally condemned. The Triumph of Orthodoxy was appointed to be celebrated every year on the first Sunday of Great Lent.

Saint Theoktistos did not live to see that Triumph, for he fell asleep in the Lord in the year 800.

Saint Theoktistos of Sicily should not be confused with Saint Theoktistos of Palestine (September 3), the companion of Saint Euthymios (January 20) in the ascetic life.
