Saint Mark the Ascetic, Christianity / Orthodoxy

Fifth century monk. May have been a disciple of Saint John Chrysostom, and friend of Saint Nilus the Ascetic, but it's questionable. Wrote over 200 texts on Spiritual Law, baptism, repentance, grace and holy works, and other topics. May have been the abbot at Ancyra, but later became a desert hermit. Opposed the Messalian heresy; it taught that each person has a personal demon that even baptism cannot conquer. Wrote against the Nestorians. Said to have known the Scriptures by heart. Legend says he once cured a hyena that had been born blind.
