Mary Baker Eddy's Church Manual provides a simple outline for conducting Sunday School. It includes a succinct guide to teaching, as well as a simple, but precise, "order of services" that includes singing and prayer. See Church Manual, pp. 62–63, 127.
Teaching the Children. Sect. 2. The Sabbath School children shall be taught the Scriptures, and they shall be instructed according to their understanding or ability to grasp the simpler meanings of the divine Principle that they are taught.
Subject for Lessons. Sect. 3. The first lessons of the children should be the Ten Commandments (Exodus 20:3–17), the Lord's Prayer (Matt. 6:9–13), and its Spiritual Interpretation by Mary Baker Eddy, Sermon on the Mount (Matt. 5:3–12). The next lessons consist of such questions and answers as are adapted to a juvenile class, and may be found in the Christian Science Quarterly Lessons, read in Church services. The instruction given by the children's teachers must not deviate from the absolute Christian Science contained in their textbook.
