Kristen Gnosis by C.W. Leadbeater is a non-fiction religious/spiritual book that presents an esoteric interpretation of Christianity, blending traditional Christian themes with mystical and Theosophical ideas. In the book, Leadbeater (a bishop in the Liberal Catholic Church and a prominent Theosophist) explores Christian doctrines for example the nature of God, the meaning of salvation, angels, grace and even concepts like reincarnation through the lens of gnosis. The work was based on an unfinished manuscript Leadbeater wrote during his lifetime and was compiled and published after his death with editorial additions.
