On page 301 of "Science and Health with Key to the Scriptures" Mrs. Eddy writes, "Few persons comprehend what Christian Science means by the word reflection." As must always be the case with scientific terms, this word should be considered spiritually in order to bring out the true interpretation as used in Christian Science. As thus considered, reflection may be said to be the infinite impartation of God to man and the universe, or the complete and perfect expression of divine Mind. But Mind and its expression, Principle and its idea, being one and infinite, as Christian Science teaches, they are indissolubly linked by an eternal bond of unity which may be termed God's law of reflection. This spiritual law, or bond of unity, is the continuous and harmonious activity of the nature and essence of God in His image and likeness, man. In other words, it is the law of divine expression, constituting the at-onement of man with God.
The dictionary defines "science" as "ascertained truth or facts;" hence divine Science is the "truth or facts" about God and His creation. Christian Science unfolds to man the spiritual facts of existence, that he may understand that Mind is omnipotent and supreme and contains within itself all true ideas. The recognition of this fact and of this perfect law of reflection operating harmoniously in Mind's idea, man, precludes the possibility of any opposing power or mind, for we cannot have more than illimitable Mind. It was his understanding of this unchangeable law which enabled Jesus, as Mrs. Eddy tells us on page 555 of Science and Health, to "restore the individualized manifestation of existence, which seemed to vanish in death," for he knew that this law of God sustains and maintains man as the idea of divine Mind, complete, perfect, and eternal.
All Christians acknowledge the healing works of Jesus; but many do not recognize the divine Principle and rule by which they were accomplished, or admit the possibility of their repetition. The scientific certainty with which these works were performed makes us admit that they were the result of the operation of some law the application of which, when understood, must be possible in this age with equal results. The questions seem to be: What is this law? How can it be applied to human problems, and what is its practical method of application?
