Elizabeth Clare Prophet, the retired leader of the Summit Lighthouse and the Church Universal and Triumphant, a New Age religion, who called on her followers in the late 1980s to prepare for nuclear Armageddon, died Thursday at her home in Bozeman, Mont. She was 70.
The cause was Alzheimer’s disease, said her daughter Erin.
Mrs. Prophet took over the leadership of the Summit Lighthouse in 1973 on the death of her husband, Mark L. Prophet. He had founded the organization in 1958 to spread a message combining elements of Christianity, Buddhism, Hinduism and Theosophy.
