Saint Gerasimus, Bishop of Great Perm and Ust’Vymsk, was the third bishop of the newly-enlightened Zyryani people, and he was a worthy successor to St Stephen, the Enlightener of Perm (April 26). He was elevated to the See of Perm sometime after 1416, and participated in many Church councils: one in 1438 to condemn the Unia and Metropolitan Isidore, and one in 1441, which defined the selection of the Metropolitan of All Rus by a Council of Russian pastors.
The saint assiduously cared for his newly-established flock, which suffered raids from Novgorodians, particularly from the pagan Vogulians. He went to their camps urging them to cease the pillaging of villages of the defenseless Christians of Perm. He was murdered by a Vogulian servant during one of his journeys through Perm in 1441 (according to Tradition, he was strangled with his omophorion). He was buried in the cathedral church of the first bishops of Perm, which later became the Annunciation church in the village of Ust’Vyma, northeast of the city of Yarenga, at the River Vychegda.
The celebration of his memory was established in 1607. On January 29 there is a general commemoration of the three Perm Hierarchs: Gerasimus, Pitirim, and Jonah.
