Miguel de Molinos
Miguel de Molinos (baptised 29 June 1628 – 29 December 1696) was a Spanish Catholic priest, spiritual director, mystical writer, and the principal figure associated with the controversy later known as Quietism. His best-known work, The Spiritual Guide (1675), was one of the most widely circulated manuals of contemplative prayer in seventeenth-century Europe before its author's condemnation by the Roman Inquisition.
