The founder of the coenobitic life in Russia, each Great Lent Saint Theodosius withdrew to the cave in which he began the ascetic life at the feet of Saint Antony (July 10th). There he prepared for the Feast of Feasts through fasting and prayer, by which he also overcame the repeated assaults of the demons. The holy abbot primarily taught the Faith through prayer, placing a special emphasis on caring for the poor. For his perseverance in prayer and charity, the Lord granted him the ability to cast out unclean spirits, heal the sick, and to know the hearts of those who came to him for help.
