ON page 107 of "Science and Health with Key to the Scriptures" Mrs. Eddy states that the Christ Science which she discovered in 1866 is the "divine laws of Life, Truth, and Love." She also declares that Christian Science is the only true Science, that it is divine and unerring in its expression of divine law. It is of more than passing significance that the period since the discovery of Christian Science has also witnessed marvelous expansion in the so-called material sciences. Above all other periods of the world's history, this has been preeminently the age of scientific investigation and discovery. So successful has been this research and so practical the application of new discoveries that the needs of mankind are being met to a degree never before accomplished or even contemplated. One enthusiastic savant has made bold to declare that so completely does modern science meet the needs of mortals that reliance upon God is no longer necessary. No more clearly could the ultimate goal of natural science be set forth than by the word of this enthusiast; for this so-called science, held to and carried to its logical conclusions, tends to the elimination of God as creator, or even as an essential factor in the universe.
But all these discoveries and inventions pertain to material science, that is, to science which deals with matter and material laws, and in consequence loses sight of God as the cause, creator, and sustainer of the universe, the infinitude of perfect ideas, the spiritual creation. The many efforts to reconcile the two views—the one, of divine Science, relating only to God and the spiritual universe, the other, of so-called science, undertaking to associate material law with the spiritual universe, to make matter synonymous with Spirit, God, either as divine substance or as an instrumentality used by God, His medium of expression— have egregiously failed. The two modes of thought are as opposite as the poles and can never be reconciled, for Spirit and matter are irreconcilable. In her transcendent discovery Mrs. Eddy establishes true Science. She lifts Science out of the realm of matter with which it had been generally involved and puts it in its rightful place as the only true Science, since it alone pertains to God, to His kingdom, the only universe, and to spiritual man, the only man.
True Science could not rest upon so unstable a foundation as matter is known to be; for with its foundation unstable and changeable, its categories would not be dependable. Discoveries in recent years have brought much doubt upon the stability of certain material laws which formerly were thought to be fixed, the very symbols of stability. It is very generally agreed that Einstein's discoveries have at least cast much doubt upon the fixity of Newton's law of gravitation; and when a "law" is found to be variable, subject to change, it has lost the very essence of law, unchangeableness.
