Monastic Life
The synaxarion relates that Eustratius came from the city of Tarsus and, at twenty years of age, secretly departed his parents' home to take up the monastic life. He settled at the Abgar monastery on Mount Olympus in Asia Minor.
There he is said to have lived a strict ascetic life, eating only bread and water and devoting his nights to prayer. He is remembered as an abbot of the region of Tarsus to whom the gift of wonderworking was granted, an epithet preserved in his commemoration.
