St. Theodosius was so inspired by Abraham’s example of leaving his loved ones and homeland for God that he left his homeland of Cappadocia to make a pilgrimage to Jerusalem. There St. Theodosius took as his guide the holy man Longinus, who placed him in charge of a church near Bethlehem. Theodosius did not stay there long, however, but he went to live in a cave on a nearby mountain.
He was known for his holiness, and many desired to dedicate their lives to God as monks under Theodosius. He built a monastery at Cathismus, as well as three hospices: for the sick, the elderly and the mentally ill. When Emperor Anastasius was persecuting Christians who did not accept the Eutychian heresy, which states that Christ has only one nature, St. Theodosius preached orthodoxy throughout Palestine, even stating from the pulpit in Jerusalem: “If anyone receives not the four general councils as the four gospels, let him be anathema.” The Saint renewed the courage of those in whom the Emperor’s edicts had instilled fear. Anastasius banished Theodosius, though he was later recalled by Anastasius’ successor. Theodosius died at the age of 105; many miracles occurred at his funeral.
