The article reviews and analyses the missionary and educational work carried out by St Nicholas the Wonderworker Brotherhood in Vyatka, founded by Archpriest Stefan Kashmensky in 1882. The Brotherhood was engaged in educating the Old Believers population of the Vyatka diocese and supported a spiritual school in Vyatka for training missionaries from among peasants. Its graduates became teachers-missionaries in children’s primary schools in villages populated by Old Believers. As brotherhood teachers got closer to students, their parents and school environment, reconciliation between Orthodox and Old Believers took place gradually. In some cases, Old Believers even converted back to the Orthodox Church.
