Episcopate and Mission among the Zyrians
Gerasimus was the third bishop of the Zyrian (Komi) people, following Saint Stephen, the enlightener of Perm, and Bishop Isaac. He was elevated to the see sometime after 1416, when only a portion of the Zyrians had yet received Christianity, and so inherited both a missionary task and the care of an exposed frontier church. One account records that he took part in synods of the Russian Church held at Moscow in 1438 and 1441.
His flock suffered repeated incursions from the Novgorodians and from the pagan Voguls, who plundered the Christian settlements of Perm. Gerasimus went in person into the Vogul camps to urge the raiders to cease their attacks on the defenseless people under his care.
