During the last decade some nations were busy instructing their youth in their ways of thinking and living. These nations were well aware that the children of today are the citizens of tomorrow, and that they will help to mold the world from the standpoint of the teaching they have imbibed. Such teaching was based largely on material knowledge, which insists that man is physical and depends on matter for his existence, that he is living in a material, limited, and destructible universe. All these theories are unchristian and therefore untrue. Such knowledge bears fruit, after its kind, in disappointment and dispute. It can never make people happy and successful, nor build better world conditions.
How important, then, it is to instruct and train youth to understand and acknowledge the spiritual facts of existence as revealed in the Bible, exemplified by Christ Jesus, and explained by Christian Science. Our Master said, "Suffer the little children to come unto me, and forbid them not." He drew them not unto the personal Jesus, but unto the Christ, Truth. Mary Baker Eddy, the revelator and Founder of Christian Science, writes in her textbook, "Science and Health with Key to the Scriptures" (p. 237): "Children should be taught the Truth-cure. Christian Science, among their first lessons, and kept from discussing or entertaining theories or thoughts about sickness. To prevent the experience of error and its sufferings, keep out of the minds of your children either sinful or diseased thoughts."
Foreseeing the necessity of right instruction for these future world citizens, Mrs. Eddy established the Christian Science Sunday School for the spiritual training and education of young people up to the age of twenty years. The lessons prescribed for the Sunday school are to be found in the Manual of The Mother Church, Article XX. These lessons are based on the inspired Word of the Bible and Science and Health. The Sunday school instructs the children in the practical application of the Christ, Truth. It trains them in the best possible way to live in peace and harmony with their fellow beings and to help build satisfying conditions for all.
