English: Saint 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 venerated both in the Eastern Orthodox Church and the Catholic Church. He is generally considered the greatest of the 19th-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 acquire the Holy Spirit. Perhaps his most popular quotation amongst Orthodox believers is "Acquire a peaceful spirit, and thousands around you will be saved." Saint Seraphim was canonized by the Russian Orthodox Church in 1903. Saint John Paul II referred to him as a saint.
