Perhaps one of the greatest of the many great healing truths revealed by the Scriptures is that there are not gods many. God, the Scriptures reveal, must be and is one because He is infinite, the All-in-all. In Isaiah we read (44:6), "Thus saith the Lord...beside me there is no God." Proclaimed Moses (Deut. 6:4), "Hear, O Israel: The Lord our God is one Lord." More than a thousand years later, when a scribe asked Christ Jesus (Mark 12:28), "Which is the first commandment of all?" part of the Master's answer consisted of quoting Moses' words, "Hear, O Israel; The Lord our God is one Lord."
One, one, one, always one, is the prolonged tone of the Christ, Truth—one All-in-all God, who is the one all-knowing Mind, the one all-governing Principle, the one all-real Truth, the one all-inclusive Spirit, the one all-comforting Love, the one ever-perfect Soul, the one eternal Life, the one indestructible substance, the one unerring intelligence, the one all-providing Father, the one ever-caring Mother.
"God is one, and His idea, image, or likeness, man, is one." This logical conclusion by Mary Baker Eddy, the Discoverer and Founder of Christian Science, is based upon the spiritual import of the Scriptures. Her statement appears on page 239 of a published collection of her writings entitled "The First Church of Christ, Scientist, and Miscellany." There can be only one genus or kind of image and likeness created by God to be the necessary evidence of His oneness. If it were otherwise, the all-pervading quality of oneness would cease to characterize God, and the belief in gods many would have a basis in fact instead of in fable. Only one God, infinitely good, and only one genus or kind of reflection, spiritual man, who is likewise limitlessly good. Such is the irrevocable law of being. It follows that mortals are not the evidence of God but only mortal misconceptions concerning God's creation, counterfeits of His perfect, incorporeal ideas.
