A disciple of the great monastic elders of Gaza, Saints Barsanuphius and John, Saint Dorotheus longed for a life of strict ascesis, but his weak bodily constitution wouldn’t allow it. Lest he fall into despair and thereby make himself a target of the Devil, the Great Old Man (Barsanuphius) consoled him and instructed him to make every effort to deny the will of the flesh through an inner ascesis of the heart. So, beginning at cutting of his will in small things, he was able to progressively cut off his will in larger things. Eventually this led him to a heavenly detachment and impassibility through which God was able to act to crush the invisible enemy. This also cultivated within him other virtues, chief among them that of humility, compassion, and resilience which he used to guide his own disciples, especially Saint Dositheus. On one occasion, the noonday demon ferociously assailed him with an overwhelming sadness and acedia. The Saint cried out to the Lord for help, and he was granted a vision of an angel in the form of a Bishop who struck Dorotheus on the breast three times repeating the Psalm verse, “With patience I waited patiently for the Lord, and He was attentive unto me, and he hearkened unto my supplication” (Psalm 39 LXX). As soon as this had happened, the angel disappeared, the demon fled, and the Saint’s heart was flooded with the Uncreated Light, joy, and peace. From that time forward he was never subjected again to sadness, acedia, or fear. The Saint’s most famous teaching on unity with both God and neighbor is known today as the Circle of Saint Dorotheos of Gaza wherein he describes a person as a point on the circumference of a circle. The person moves inward towards God represented as the point at the center of the circle. As the person draws nearer to God, they also draw near to others making the same journey as their paths converge. Thus he taught that, while our salvation is a gift from God, it also lies in our neighbor. Such a blessed unity cannot be overcome by the Enemy of Mankind.
