On page vii of the Preface to "Science and Health with Key to the Scriptures" by Mrs. Eddy are to be found these arresting words: "The time for thinkers has come. Truth, independent of doctrines and time-honored systems, knocks at the portal of humanity." This is a clarion call to men and women everywhere to think for themselves, to think independently, to think correctly on fundamentals — on reality, God and His creation.
No matter how much unenlightened human thought may argue to the contrary, it is certain that Christian Science reveals the truth, the absolute truth about God and His creation. It is not possible to give a full statement of this truth in a brief writing, but certain spiritual facts can be stated to show its nature. It is possible to enunciate the truth about God and His creation and to do so without ambiguity.
Christian Science, then, affirms that God is omnipotent, omnipresent, omniscient Mind. This means that there is only one real presence, one real power, one real intelligence. Christian Science affirms, further, that God is good. Hence, good is the only real presence and power. Thus, the truth which Christian Science is declaring to mankind is that God is All-in-all and that He is good. Inferentially, evil is without presence, power, or intelligence; or, in other words, evil is unreal.
