In the period following the revolution, and during the communist persecutions up to 1970, no canonizations took place. Only in 1970 did the Holy Synod made a decision to canonize a missionary to Japan, Nicholas Kasatkin (1836–1912). In 1977, St. Innocent of Moscow (1797–1879), the Metropolitan of Siberia, the Far East, the Aleutian Islands, Alaska, and Moscow was also canonized. In 1978 it was proclaimed that the Russian Orthodox Church had created a prayer order for Meletius of Kharkov, which practically signified his canonization because that was the only possible way to do it at that time. Similarly, the saints of other Orthodox Churches were added to the Church calendar: in 1962 St. John the Russian, in 1970 St. Herman of Alaska, in 1993 Silouan the Athonite, the elder of Mount Athos, already canonized in 1987 by the Ecumenical Patriarchate of Constantinople. In the 1980s the Russian Orthodox Church re-established the process for canonization; a practice that had ceased for half a century.
