The Christian Science pastor is unique. In 1895, Mary Baker Eddy ordained the Bible and Science and Health with Key to the Scriptures, the Christian Science textbook, to be the pastor of all Christian Science churches. In the Sunday service, two Readers (members of the church elected to serve) read correlative passages from these two books. This sermon, read on Sunday, is taken from the weekly published Christian Science Bible Lesson - this is read throughout the world at every Christian Science church, society and gathering. Readings from the Bible and Science and Health with Key to the Scriptures begin the Wednesday meetings.
The textbook, Science and Health with Key to the Scriptures was first published in 1875 by Mary Baker Eddy, the Discoverer and Founder of Christian Science. This prayer based system was discovered in 1866, when Mrs. Eddy was healed of a serious injury by reading one of Jesus' healings in the Bible. The rest of her life was dedicated to teaching this Christ-based healing method to the world.
