Ascetic Life
Marcian withdrew to the desert near Cyrrhus and built a small cell, where he lived in solitude given over to unceasing prayer and strict fasting, taking only the minimal food needed to remain alive.
According to the tradition, a divine light filled his cell during his nighttime prayer and reading, so that he had no need of candles or lamps.
Though he founded a monastery for the ascetics who were drawn to his manner of life, accounts also describe him accepting only two disciples who settled nearby while he maintained his own solitary practice.
Teaching and Defense of the Faith
Patriarch Flavian of Antioch and other bishops entreated Marcian to leave his cell for a public ministry, but he refused to abandon his strict solitude.
He did, however, instruct those who visited him seeking guidance, and through his teaching at his cell he is said to have turned many away from heresy and led them to the Orthodox faith.
Miracles and Traditions
Historically Documented: His life and ascetic practices were recorded by Theodoret of Cyrrhus, bishop of Cyrrhus and a near-contemporary, in the Historia Religiosa (also called the Philotheos historia, or A History of the Monks of Syria), generally dated to about 444. The work gathers biographies of thirty Syrian ascetics and anchorites as religious models, and includes Marcian among them, making it a primary hagiographic source for the monasticism of fourth-century northern Syria.
Traditional Accounts: The synaxarion relates that a serpent once entered Marcian's cell, and that at the sign of the Cross it perished, burned up by flames. The same tradition holds that a heavenly light shone for him as he read at night, and that he worked many other miracles on behalf of the brethren; he is credited with the gift of wonderworking and healing.
Repose and Relics
Marcian died in peace about the year 388.
By tradition he had a principal disciple named Eusebius, whom he instructed to bury him secretly and far from his cell, so as to avoid posthumous veneration and to prevent disputes among churches over his relics.
