Unity of Good is considered by many to be Mrs. Eddy’s most profound work apart from the textbook. In it she explains how the allness of God, good, makes the unreality of evil and matter a scientific fact. She reasons: “As God is Mind, if this Mind is familiar with evil, all cannot be good therein. Our infinite model would be taken away. What is in eternal Mind must be reflected in man, Mind’s image. How can man escape or hope to escape from a knowledge which is everlasting in his creator?” The pure logic in this concept of the allness of God and the illusion of evil and matter is a breakthrough in both the religious and scientific worlds. Everyone seeking to understand God should study this profound statement.
