Reading from the Synaxarion:

Holy Father Auxentius of the Mountain

This Saint, who was from the East, lived during the reign of Saint Theodosius the Younger. In 442 he enlisted in the Fourth Military Company of the Scholarii, that is, the Imperial Guard. Afterwards, he became a monk on a certain mountain in Bithynia (which later took his name), not far from Chalcedon. On becoming the archimandrite of the monastics gathered there, and proving himself to be most enduring in asceticism and most Orthodox in his faith, he reposed during the reign of the Emperor Leo the Great of Thrace, who reigned from 457 to 474.
