Christian Science was discovered by Mary Baker Eddy in 1868, while reading one of Jesus’ healings in the Bible, Mrs. Eddy was completely healed of an injury from which she had not been expected to recover. She then dedicated herself to finding the principle behind that healing. She immersed herself in study of the Bible, wrote voluminously of her insights, and healed others by applying what she was learning. Eventually she recorded her findings in Science and Health with Key to the Scriptures.
While she hoped Christian Science would be incorporated into the mainstream religions of her day, Mrs. Eddy eventually felt the need to establish her own church, The first Church of Christ, Scientist, in Boston, MA. Often referred to as The Mother Church, it serves as the worldwide headquarters to branch churches around the globe.
