from Mary Baker Eddy 
“Question. – What is the scientific statement of being?
Answer. – There is no life, truth, intelligence, nor substance in matter. All is infinite Mind and its infinite manifestation, for God is All-in-all. Spirit is immortal Truth; matter is mortal error. Spirit is the real and eternal; matter is the unreal and temporal. Spirit is God, and man is His image and likeness. Therefore man is not material; he is spiritual.”

Mary Baker Eddy is the Discover and Founder of Christian Science and the Author of the Textbook of Christian Science, Science And Health with Key to the Scriptures. This Question and Answer can be found on page 468, lines 8-15, in CHAPTER XIV RECAPITULATION.

For precept must be upon precept; precept upon precept; line upon
line, line upon line; here a little, and there a little. – Isaiah.

THIS chapter of QUESTIONS AND ANSWERS is from the first edition of the author’s class-book, copyrighted in 1870. After much labor and increased spiritual understanding, she revised that treatise for this volume in 1875. Absolute Christian Science pervades its statements, to elucidate scientific metaphysics.
