Seraphim of Sarov, Russian monk and saint (b. 1759)
Seraphim of Sarov (Russian: Серафим Саровский; 30 July [O.S. 19 July] 1754 (or 1759) – 14 January [O.S. 2 January] 1833), born Prokhor Moshnin (Прохор Мошнин), is one of the most renowned Russian saints and is venerated in the Eastern Orthodox Church. 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. He taught that the purpose of the Christian life was to receive the Holy Spirit. Perhaps his most popular quotation amongst his devotees is "acquire a peaceful spirit, and thousands around you will be saved."

Seraphim was glorifed by the Russian Orthodox Church in 1903. Pope John Paul II also referred to him as a saint.
