Elizabeth Clare Prophet was a new age spiritual leader and author of more than fifty books which have sold more than a million copies and been translated into a dozen languages. She carried on a teaching and healing ministry for thirty-six years. She held a degree in political science from Boston University. She began her spiritual quest in Christian Science and continued through The Summit Lighthouse, a group founded by her late husband, Mark L. Prophet, in 1958. His was one of several groups to promote the teachings of the ascended masters, believed to be a group of unseen saints and sages. Both Prophets claimed to receive messages from the ascended masters. After Mark's death in 1973, Elizabeth carried on her spiritual work through Church Universal and Triumphant, which she founded in 1975. Prophet's lectures, sermons, and rituals are available on hundreds of audio- and videotapes. Her most popular books include "The Lost Years of Jesus" and "How to Contact Your Higher Self." In 1981, the church purchased a headquarters at Corwin Springs, Montana, near Yellowstone Park. In 1998, at the age of 59, she was diagnosed with early-onset Alzheimer's disease. Two years later, she moved from the church's headquarters to Bozeman, Montana, where she lived near her family until her death in 2009. She was the mother of five children.
