When Mrs. Eddy gave its final, full name to the textbook that she wrote to explain and establish her discovery of Christian Science, she decided upon the title, Science and Health with Key to the Scriptures. Actually, this title connects health with law, since a science operates within the framework of law and requires obedience to law. "Key to the Scriptures" links Science with Christianity, and health with the healings recorded in the Bible, particularly those of Christ Jesus.
Mrs. Eddy had glimpsed the connection between law and health when she was healed of the effects of an accident feared to be fatal. Then, through Bible research, prayer, and demonstration, the revelation came to her of the healing Principle by which Christian worship must be characterized. So she could assert in the textbook, "If Christianity is not scientific, and Science is not of God, then there is no invariable law, and truth becomes an accident." Science and Health, p. 342;
Of Science and Health itself Mrs. Eddy writes: "Although this volume contains the complete Science of Mind-healing, never believe that you can absorb the whole meaning of the Science by a simple perusal of this book. The book needs to be studied, and the demonstration of the rules of scientific healing will plant you firmly on the spiritual groundwork of Christian Science."
