Christian Science is a religion founded in the late 1800's by a woman named Mary Baker Eddy. The faith, and the church Mrs. Eddy established to practice its principles, focuses on the healing ministry of Jesus Christ and focuses on demonstrating those same healing practices in contemporary times. Our pastor is the Bible and the Christian Science textbook, Science and Health with Key to the Scriptures, written by Mrs. Eddy.
