In recording the steps which she took to establish the Science of Christianity, Mary Baker Eddy writes: "I knew the Principle of all harmonious Mind-action to be God, and that cures were produced in primitive Christian healing by holy, uplifting faith; but I must know the Science of this healing, and I won my way to absolute conclusions through divine revelation, reason, and demonstration" (Science and Health with Key to the Scriptures, p. 109). She recognized how momentous was her discovery, changing human standpoints and opening up incalculable avenues of salvation for mankind. It meant, if it were to be pursued and adopted, a revolutionary attitude not only towards the problems which beset humanity, individually and collectively, but actually towards God Himself.
In common with all really great searches after scientific enlightenment, our Leader was inflexible in her determination and tireless in her labors to prove the truth of her discovery by testing it from every angle. What she gave to the world must not only be the result of the spiritual revelation which had come to her, and raised her up to health and greater usefulness; it must be proved correct along every line of approach, and be built upon a rock so impregnable that the storms, whether of incredulity or skepticism, of animosity of prejudice, would hurl themselves against it in vain.
Thus it was that for three years Mrs. Eddy "sought the solution of this problem of Mind-healing" (ibid.), until she could write, "I won my way to absolute conclusions through divine revelation, reason, and demonstration." These were the means by which the Principle and rule of Truth were made accessible to mankind.
