The following metaphysics statement comes from the healing textbook Science and Health with Key to the Scriptures by Mary Baker Eddy which is based on the Bible. It is a key statement in Christian Science healing because it helps lift thought above our physical person to our true nature as the image and likeness of God. Genesis 1:26.
Chapter 14 in Science and Health is titled "Recapitulation" and contains questions and answers on Christian Science.
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. SH 468:8-15
