Throughout the ages God has been the rock upon which all things worthwhile have been built. We read in the Bible (Deut. 32:4), "He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he."
Mary Baker Eddy defines "rock" in her textbook, "Science and Health with Key to the Scriptures" (p. 593), in part as "spiritual foundation; Truth." Not only did the inspired Leader of the Christian Science movement establish her system of religion upon the rock, the spiritual foundation of Christ, Truth, but she bravely and boldly called it the Science of Christianity, thereby causing the old schools of orthodox theology to scorn and scoff. But why should not Christianity be called Science? Can there be any more workable or provable knowledge than the Word of God? Moreover, the textbook of Christian Science fairly teems with rules for demonstration of its facts.
Jesus was the greatest demonstrator of the Christ, Truth, the world has ever known. He overcame all error, even to the point of laying off his material embodiment and putting on his spiritual identity. Yet Jesus, our supreme Exemplar, left us no textbook, no accurate set of rules whereby we can demonstrate over all material limitations as he did. It remained for the Comforter, divine Science, to provide these rules.
