Saint Arsenius, originally from Constantinople, was a military commander and a patrician of Kiveriot. After being saved from shipwreck, he renounced the world and embraced monasticism, dedicating himself to prayer, fasting, and vigil. On Mount Latrus in Asia Minor, he defeated a deadly asp through prayer and the sign of the Cross, and then became the abbot of the Kellivarian Monastery, but withdrew to a cave from which he drove away wild beasts. Brothers gathered around him, whom he guided by his example and teaching. The saint spent an entire week in silence, and on Sundays he taught and took food. He attained spiritual perfection, was a companion of Angels, performed miracles, including turning bitter waters into sweet, and peacefully departed among the brethren.
