The Lectorium Rosicrucianum or International School of the Golden Rosycross is a Spiritual School which considers itself a worldwide school of Esoteric Christianity. It was founded in 1935 by Dutch mystics Jan van Rijckenborgh, his brother Zwier Willem Leene and Catharose de Petri. The school teaches a form of modern Christian Gnosticism which is based upon the ideas and iconography of Rosicrucianism, the beliefs of the Cathars and other forms of religio-mystical thought such as Hermeticism and alchemy. Although it was suppressed by the Nazis during World War 2, the Lectorium Rosicrucianum now counts about 15,000 members and has branches in countries all over the world in all continents except Asia and Antarctica.
