He was one of those confessors who, under the tyrant Maximin Daia, lost their right eye, and were afterward sent to work in the mines. Peace being restored to the Church, Paphnutius returned to his flock. The Arian heresy being broached in Egypt, he was one of the most zealous in defending the Catholic faith, and for his eminent sanctity and the glorious title of confessor (or one who had confessed the Faith before the persecutors and under torments) was highly considered in the great Council of Nice. Constantine the Great, during the celebration of that synod, sometimes conferred privately with him in his palace, and never dismissed him without kissing respectfully the place which had once held the eye he had lost for the Faith. St. Paphnutius remained always in a close union with St. Athanasius, and accompanied him to the Council of Tyre, in 335, where they found much the greater part of that assembly to be professed Arians. Seeing Maximus, Bishop of Jerusalem, among them, Paphnutius took him by the hand, led him out, and told him he could not see that any who bore the same marks as he in defence of the Faith should be seduced and imposed upon by persons who were resolved to oppress the most strenuous assertor of its fundamental article. We have no particular account of the death of St. Paphnutius, but his name stands in the Roman Martyrology on the 11th of September.
Feast Day of Saint Paphnutius
The Feast Day of Saint Paphnutius is September 11. The origin of Feast Days: most saints have specially designated feast days and are associated with a specific day of the year and these are referred to as the saint's feast day. The feast days first arose from the very early Christian custom of the annual commemoration of martyrs on the dates of their deaths at the same time celebrating their birth into heaven.
