From 1657, Mezenets was a clerk (editor) at the Moscow printing house.
He took monastic vows in the Zvenyhorod New Jerusalem Ascension Monastery of the Moscow diocese. From 1668 he was a member of the Council of this monastery. He headed a commission that was to correct Moscow church music books and reform church singing and the musical notation of the "hook banner".
He is one of the authors of the theoretical work The Alphabet of Sign Singing (1688), which is the most complete exposition of the theory of sign singing.
