Mark, Bishop of Ephesus
The great teacher and invincible defender of the One, Holy, Catholic, and Apostolic Church, Saint Mark, was the offspring and scion of the imperial city, Constantinople. Reared by most pious parents, and instructed in secular and spiritual wisdom, he became preeminent in both. Saint Mark lived as an ascetic on the Prince's Islands and later in the monastery of Saint George Magana in Constantinople. He passed through all the degrees of the priesthood, and was finally advanced to the dignity of Archbishop and the lofty throne of the Metropolis of Ephesus. At the insistence of Emperor John Paleologos, the Saint was sent to the council of the Latins in Florence, to unite the churches that had been divided for so many years. He astounded the papal teachers with the divine wisdom of his words, and was the only one who did not sign the blasphemous decree of that false council. Because of this, the Holy Church of Christ has ever honored this great man as a benefactor, teacher, sole defender, and invincible champion of the Apostolic Confession. He reposed in 1443.
