Our venerable and God-bearing Father Symeon the Stylite
He was born in Syria of peasant parents. At the age of eighteen, he left home and was tonsured a monk. He undertook the most difficult ascetic practices, and sometimes undertook a strict fast for forty days. He eventually took upon himself a form of asceticism that was previously unknown. He stood day and night on a pillar, in unceasing prayer. At first, his pillar was six cubits high; he later raised it to twelve cubits, then to twenty-two cubits, then to thirty-six cubits, and finally to forty cubits high. On two occasions his mother Martha came to see him, but he refused to receive her, saying from atop the pillar: "Do not disturb me now, my mother. If we become worthy, then we'll see each other in the next world". St. Simeon endured countless assaults from demons, but he conquered them all by prayer to God. The saint worked many great miracles, healing by word and prayer many who were afflicted. People from all over gathered around his pillar-the rich and the poor, kings and slaves. Simeon helped everyone: healing some of infirmities, comforting those in need, instructing others, and reproaching some who held heretical beliefs. Thus, he turned Empress Eudocia from the Eutychian heresy and brought her back to Orthodoxy. He lived the ascetic life during the reigns of the Emperors Theodosius the Younger, Marcian and Leo the Great. Simeon, the first great stylite in Christianity and a great miracle-worker, lived to be 103 years old. He reposed in the Lord on September 1, 459. His relics were translated to Antioch, to the church dedicated to his name.
