Seraphim of Sarov, born Prókhor Isídorovich Moshnín (Mashnín) [Про́хор Иси́дорович Мошни́н (Машни́н)], is one of the most renowned Russian saints and is venerated in the Eastern Orthodox Church and the Anglican Communion. He is generally considered the greatest of the 18th-century startsy (elders). Seraphim extended the monastic teachings of contemplation, theoria and self-denial to the layperson.
