Christian Science (or the Church of Christ, Scientist) was founded in the 1800s by Mary Baker Eddy (Mrs. Eddy as she was known in the Church). She dabbled in "healing arts" that she studied from an old clockmaker turned snake-oil man but, after a bad fall many didnt' think she'd survive, Mrs. Eddy discovered the "true power of healing."
Rather than seek to be healed by an internal process or by the mind, Mrs. Eddy discovered that healing could come only from the "Divine Mind of God," and she was
healed on the spot.
She developed a "science" of healing based on her discovery of the "science of scripture" in the Christian Bible. Modern Christian Scientists adhere to Mary Eddy's principle tenents, which she outlined in her book,
Science and health with key to the scriptures. Among them: "as adherents of Truth, we take the inspired Word of the Bible as our sufficient guide to eternal Life"; and "we acknowledge that the crucifixion of Jesus and his resurrection served to uplift faith to understand eternal Life, even the allness of Soul, Spirit, and the nothingness of matter."
I think these tenents as well as others of Christian Science make it clear that this cult is
at least as different from the various Muslim cults as the Presbyterians or Jehovah's Witnesses.
