Episcopate during the Time of Troubles
Theodoritus was consecrated to the see of Ryazan and Murom in August 1605, at the outset of the Time of Troubles, the decade of dynastic crisis, foreign intervention, and civil conflict that followed the extinction of the old Muscovite line. According to the tradition recorded of him, he was present at the wedding of the first False Dmitri to Marina Mniszech in May 1606, and after Dmitri's overthrow took part in the coronation of Tsar Vasily Shuysky.
With the support of Tsar Vasily Shuysky he undertook the construction of the Dormition (Assumption) Cathedral in Ryazan, which became the principal church of his see. His tenure thus spanned the most disordered years of the early seventeenth century, when the Ryazan lands lay along the contested southern frontier of the Muscovite state.
