After Saint Pitirim, Saint Jonah ascended the throne of Perm. He converted to Christianity the remaining part of Great Perm, i.e. the pagan tribes living along the Rivers Vishera, Kama, Chusova and others. By his efforts the idols were eradicated and in their place churches were built. Experienced pastors were sent to teach the new converts at the church-run schools of Us-Vym.
Saint Jonah reposed on June 6, 1470. His relics rest together with the relics of Saints Gerasimus and Pitirim in the Annunciation temple in Ust-Vym (in Vologda district).
The commemoration in common of these three saints acknowledges their apostolic activity in this Eastern expanse of Russia. Saint Jonah is also commemorated on June 6.
