Mark is rather an ascetic than a dogmatic writer He is content to accept dogmas from the Church. His interest is in the spiritual life as it should be led by monks.
Various theories about his period and works have been advanced.
According to Johannes Kunze, Mark the Hermit was superior of a laura at Ancyra. He then as an old man left his monastery and became a hermit, probably in the desert east of Palestine, near Saint Sabas.
He was a contemporary of Nestorius and died probably before the Council of Chalcedon (451). Nicephorus Callistus (fourteenth century) says he was a disciple of John Chrysostom.
Cardinal Bellarmine thought that this Mark was the monk who prophesied ten more years of life to the Emperor Leo VI in 900.
He is refuted by Tillemont. Another view supported by the Byzantine Menaia identifies him with the Egyptian monk mentioned in Palladius, who lived in the fourth century. According to a brief entry in the "Great Synaxaristes" of the Orthodox Church, his feast day is observed on May 20.
