The First Church of Christ, Scientist, commonly known as Christian Science, is a religious organization founded in the late 19th century by Mary Baker Eddy. It emphasizes the healing power of prayer and the study of the Bible, particularly the teachings of Jesus Christ. The church promotes the idea that spiritual understanding can lead to physical and emotional healing. The church's main text is Science and Health with Key to the Scriptures, written by Eddy, which outlines its core beliefs and practices. Services typically include readings from the Bible and Eddy's writings, and the church operates a network of Christian Science Reading Rooms for community education and resources.
