When the Soviet state imposed the Gregorian calendar on Russia in 1918, it issued a direct challenge to the liturgical identity of the Russian Orthodox Church. The Bolsheviks understood precisely what they were doing - compelling the Patriarch's agreement to calendar reform would fracture the Church's moral authority from within and associate her feasts, fasting cycles, and Paschal reckoning with an atheist government. The calendar was never merely a question of dates. It was a question of who held sovereignty over the life of the Church.

This volume gathers four primary documents in which Patriarch Tikhon of Moscow confronted that question directly. Writing under surveillance, house arrest, and constant governmental pressure, he navigated the impossible terrain between institutional survival and canonical integrity - producing texts that remain among the most significant witnesses to the Church's resistance under Soviet totalitarianism.

The four documents presented here in English translation are: his message to Patriarch German of Constantinople situating the Russian Church within the broader Pan-Orthodox calendar controversy; his pastoral message to the Orthodox faithful calling them to patience and fidelity; his formal statement to the Soviet Central Executive Committee on September 17/30, 1924; and his decree suspending the introduction of the New Style following the immediate and widespread resistance of the faithful.

Together they do not present a man who capitulated. They present a man who maneuvered - carefully, pastorally, and at great personal cost - to preserve the Church's liturgical life under a government determined to dismantle it.

St. Tikhon of Moscow was canonized by the Russian Orthodox Church in 1989. His relics, long presumed lost, were discovered incorrupt at Donskoy Monastery in Moscow in 1992.
