Science & Health with Key to The Scriptures
"A book introduces new thoughts, but it cannot make them speedily understood. It is the task of the sturdy pioneer to hew the tall oak and to cut the rough granite. Future ages must declare what the pioneer has accomplished. Since the author's discovery of the might of Truth in the treatment of disease as well as of sin, her system has been fully tested and has not been found wanting; but to reach the heights of Christian Science, man must live in obedience to its divine Principle." Mary Baker Eddy, Science and Health p. vii-viii
In following these leadings of scientific revelation, the Bible was my only textbook. The Scriptures were illumined; reason and revelation were reconciled, and afterwards the truth of Christian Science was demonstrated. No human pen nor tongue taught me the Science contained in this book, Science and Health; and neither tongue nor pen can overthrow it. This book may be distorted by shallow criticism or by careless or malicious students, and its ideas may be temporarily abused and misrepresented; but the Science and truth therein will forever remain to be discerned and demonstrated.
The demonstration lost and found
Jesus demonstrated the power of Christian Science to heal mortal minds and bodies. But this power was lost sight of, and must again be spiritually discerned, taught, and demonstrated according to Christ's command, with "signs following." Its Science must be apprehended by as many as believe on Christ and spiritually understand Truth." Mary Baker Eddy, Science and Health p. 110
The Precious Volume
The first edition of my most important work, Science and Health, containing the complete statement of Christian Science, — the term employed by me to express the divine, or spiritual, Science of Mind-healing, was published in 1875.
Even the Scriptures gave no direct interpretation of the scientific basis for demonstrating the spiritual Principle of healing, until our heavenly Father saw fit, through the Key to the Scriptures, in Science and Health, to unlock this "mystery of godliness."
Science and Health is the textbook of Christian Science. Whosoever learns the letter of this book, must also gain its spiritual significance, in order to demonstrate Christian Science. Mary Baker Eddy, Prose Works
