It is, so far as you perceive and understand this predicate and postulate of Mind-healing; but the Science of Mind-healing is best understood in practical demonstration. The proof of what you apprehend, in the simplest definite and absolute form of healing, can alone answer this question of how much you understand of Christian Science Mind-healing. Not that all healing is Science, by any means; but that the simplest case, healed in Science, is as demonstrably scientific, in a small degree, as the most difficult case so treated. The infinite and subtler conceptions and consistencies of Christian Science are set forth in my work Science and Health. _Is man material or spiritual?_ In Science, man is the manifest reflection of God, perfect and immortal Mind. He is the likeness of God; and His likeness would be lost if inverted or perverted. According to the evidence of the so-called physical senses, man is material, fallen, sick, depraved, mortal. Science and spiritual sense contradict this, and they afford the only true evidence of the being of God and man, the material evidence being wholly false. Jesus said of personal evil, that "the truth abode not in him," because there is no material sense. Matter, as matter, has neither sensation nor personal intelligence. As a pretension to be Mind, matter is a lie, and "the father of lies;" Mind is not in matter, and Spirit cannot originate its opposite, named matter. According to divine Science, Spirit no more changes its species, by evolving matter from Spirit, than natural science, so-called, or material laws, bring about alteration of species by transforming minerals into vegetables or plants into animals,--thus confusing and confounding the three great kingdoms. No rock brings forth an apple; no pine-tree produces a mammal or provides breast-milk for babes. To sense, the lion of to-day is the lion of six thousand years ago; but in Science, Spirit sends forth its own harmless likeness. _How should I undertake to demonstrate Christian Science in healing the sick?_ As I have given you only an epitome of the Principle, so I can give you here nothing but an outline of the practice. Be honest, be true to thyself, and true to others; then it follows thou wilt be strong in God, the eternal good. Heal through Truth and Love; there is no other healer. In all moral revolutions, from a lower to a higher condition of thought and action, Truth is in the minority and error has the majority. It is not otherwise in the field of Mind-healing. The man who calls himself a Christian Scientist, yet is false to God and man, is also uttering falsehood about good. This falsity shuts against him the Truth and the Principle of Science, but opens a way whereby, through will-power, sense may say the unchristian practitioner can heal; but Science shows that he makes morally worse the invalid whom he is supposed to cure.
