Looking for sound guidance in how best to teach Christian Science to a Sunday School class, we turn naturally to the Manual of The Mother Church by Mrs. Eddy. Here our Leader requires (Art. XX, 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."
Not only does she make this stipulation but she repeats it. Farther along in the same article (Sect. 3) she specifies, "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."
We are instructed to teach not only "according to their understanding" but also so that even our use of the question-and-answer method is "adapted to a juvenile class."
