Joasaph was archimandrite of the Rozhdestvenskii (Nativity) Monastery in Vladimir from 1654 to April 25, 1656, when he was named archimandrite of the Trinity-St. Sergius Lavra. In 1666, he was a member of the court that tried Patriarch Nikon and deposed him, although it also approved his reforms that had led to the Old Believer Schism.
