As one becomes a student of the Christian Science textbook, "Science and Health with Key to the Scriptures," he sees clearly why Mary Baker Eddy, its author and the revelator of this Science, aptly termed her book the Key to the Scriptures, for in the light of the revealed Christ, Truth, which this book presents, the pages of the Bible become illuminated and take on a deeper and far more spiritual meaning than a mere literal reading of the Scriptures would ever convey.
