On pages 9 and 10 of "Unity of Good" Mrs. Eddy writes: "What is the cardinal point of the difference in my metaphysical system? This: that by knowing the unreality of disease, sin, and death, you demonstrate the allness of God." And a sentence or two farther on she says, "It would be difficult to name any previous teachers, save Jesus and his apostles, who have thus taught." Two things stand out in that pronouncement by the Discoverer and Founder of Christian Science, namely, that Christian Science teaches the allness of God, and that sin, disease, and death are unreal.
Since God is All-in-all, since He is infinite, nothing the opposite of God exists in real being; nothing opposed to Him has any reality. But does not this affirmation of God's allness flatly contradict the beliefs of mortals? It does, for it means that what mortals call matter and evil have no real existence; that they are unreal, that they are but false or illusory beliefs of the so-called carnal or mortal mind. Moreover, since matter and evil are unreal, everything associated with them, as derivatives, such as sin, disease, sorrow, and death, are likewise unreal.
At the very beginning of his study of Christian Science the student is brought face to face with these great truths. He is immediately confronted with the facts of God's allness and matter's and evil's nothingness; and as an intelligent person, he is forced to weigh their significance in their bearing on the experiences of human existence. He cannot escape this; and being sincere he can have no desire to do so.
