Gury of Kazan
Gregory Grigoroevic Rugotin was born in Radonezh to a poor but aristocratic family. He entered the service of Prince Ivan Penkov, where after some years he was unjustly accused of having an affair with the wife of the prince, for which he was thrown into prison. It is said that after two years, he was miraculously released one day when his cell was filled with extraordinary light and the door was opened.
Upon leaving prison, he joined the monastery of St. Joseph of Volokolamsk, where he was tonsured with the name Gurias. In 1543, he became the abbot (hegumenos) of the monastery. After serving in this capacity until 1552, he left the position and lived for 2 years as a simple monk.
