When the Master said to his disciples (John 16:12, 13), "I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth," evidently he knew that the thought of the world was not yet ready to receive the final revelation of Christ, Truth. Doubtless, however, he foresaw that when the thought of men was fully prepared, there would be one who could receive and give to humanity the final revelation to which he referred, variously, as "the Holy Ghost," "the Comforter," and "the Spirit of truth," which he promised would lead "into all truth."
Christian Scientists understand the Comforter to be divine Science, or Christian Science, as it has been called by its Discoverer, Mary Baker Eddy. Writing of her discovery on page 107 of "Science and Health with Key to the Scriptures," Mrs. Eddy says: "In the year 1866, I discovered the Christ Science or divine laws of Life, Truth, and Love, and named my discovery Christian Science. God had been graciously preparing me during many years for the reception of this final revelation of the absolute divine Principle of scientific mental healing." It is evident from the foregoing that the revelator of Truth in this age believed her revelation to be final and complete. And it is so regarded by students of Christian Science who have progressed sufficiently far in their study to have learned its true nature.
For Christian Scientists to accept Christian Science as the final and complete revelation of Christ, for this age and for succeeding ages, does not mean that they themselves have fully grasped this Science or that they have attained to perfection in its demonstration. To the extent, however, that they do, they are proving in their own experience the finality and completeness of the revelation. And Mrs. Eddy has written (ibid., p. 147): "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."
