Christian Science churches in Spearfish South Dakota, United States

Christian Science is a set of beliefs and practices belonging to the metaphysical family of new religious movements.[n 2] It was developed in 19th-century New England by Mary Baker Eddy, who argued in her 1875 book Science and Health that sickness is an illusion that can be corrected by prayer alone.[n 3] The book became Christian Science's central text, along with the Bible, and by 2001 had sold over nine million copies.[4]
