To the man who called him "Good Master" Jesus said, "There is none good but one, that is, God;" and the Bible also states that "God is no respecter of persons." These truths, that God alone is good and the source of all good, and that He provides an infinitude of good for all His ideas, are essential in the practice of Christian Science.
Christian Science, teaching the love, the goodness, the allness, the omnipotence, and the omnipresence of God, states as an absolute corollary thereto the unreality of error, or the claim of a power apart from God. It teaches that since there is no reality in error there can, scientifically speaking, be no relative states of evil. Actually, therefore, error is neither great nor small; it is neither individual nor universal. It simply is not. Being the opposite of God, or good, error is unreal, because it did not come from God. We therefore need not fear evil in any form, for whether it claims to be great or small it is the same old lie, the same old nothingness. We cannot, however, ignore the claims of error through the mere statement of its unreality. We need to declare and realize and prove its nothingness through understanding the allness and omnipotence of God, good.
As Christian Scientists we have no right to invade the consciousness of another with a treatment unasked, but we can declare the above truths impersonally whenever the opportunity presents itself. We can know and hold to the real man's perfection as God's image or idea. We can acknowledge that the full and complete reflection of divine perfection, divine goodness, divine protection, belongs by divine right to all men everywhere—regardless of station, wealth, age, position, or any other evidence of the material senses—for in reality there is only the true, spiritual man. This truth is part of the universality of Christian Science.
