It is safe to say that one of the best known and most widely quoted passages in the Christian Science textbook, "Science and Health with Key to the Scriptures" by Mary Baker Eddy, is "the scientific statement of being," which declares in part (p. 468): "There is no life, truth, intelligence, nor substance in matter. All is infinite Mind and its infinite manifestation, for God is All-in-all." This revolutionary statement would be beyond human credence were it not for the fact that untold numbers of students of Christian Science have proved it to be true. It is on this great truth, the allness of God and the nothingness of matter, that Christian Science rests.
From beginning to end the textbook contains a logical, consistent exposition of the truths of being, which must be accepted in their entirety, even if not wholly understood, before they become operative in human affairs. It is not conducive to demonstration to declare audibly that God is All-in-all but to believe secretly that He is nearly All-in-all; or to proclaim that there is no substance in matter but to believe that after all there may be a little substance in matter.
The statement that God is All implies completeness, self-containment, and this means that there is always, existing and available, adequate supply for every need, a correct answer to every question, a sure solution to every problem. These things go together as definitely as the fact that three times four and the product twelve are inseparable everywhere, at all times and under all circumstances.
