What is the key to dynamic Sunday School teaching? What is it that can make the presentation of Christian Science so potent and effective, so fruitful in growth and experience, that the pupils will want to be present at every single session and will gratefully attend Sunday School up to the prescribed limit of attendance, their twentieth birthday? Our Leader, Mary Baker Eddy, writes in "Science and Health with Key to the Scriptures" (p. 274), "Divine Science is absolute, and permits no halfway position in learning its Principle and rule—establishing it by demonstration." It is not the province of our Sunday Schools to function in a halfway position. The keynote to the effective study of Christian Science in the Sunday School, as well as out of it, is demonstration.
All sciences begin with basic propositions to be proved. A quick review of the introduction to algebra, geometry, or physics will verify this. The basic propositions of Christian Science are the actuality and allness of Spirit and good, the unreality and nothingness of matter and evil, the invariableness of the perfection of man in the image and likeness of God, forever the beloved child of His care. These fundamental propositions will be proved in all demonstrations of Christian Science. The process of demonstration is the understanding affirmation of the truth and the denial of error until the truth is realized. The best means of teaching the children this process is to have them apply it themselves in their everyday experiences.
One young lad arrived at Sunday School disconsolate because he had had to give up his dog when his family moved into a city apartment. His Sunday School teacher showed him that under God's omnipotent government he could not be deprived of right companionship. The next Sunday he joyously reported that the landlady had suggested that his mother buy him a kitten and that it was "the cunningest thing."
