Christian Science teaches that Christ, Truth, is of God and has been always present; that Christ Jesus taught and demonstrated this Truth more than any other person; that the healing power of Truth was lost to the world from about the third century until 1866, when Mary Baker Eddy, a spiritually-minded New England woman, rediscovered it, and gave the fruits of her labors to a skeptical world, in "Science and Health with Key to the Scriptures" and her other writings, including the periodicals she founded.
