On page 111 of "Science and Health with Key to the Scriptures" Mrs. Eddy writes, "The Principle of divine metaphysics is God; the practice of divine metaphysics is the utilization of the power of Truth over error; its rules demonstrate its Science."
Both the basis and the action of Christian Science treatment are set forth in the above quotation from the Christian Science textbook. As its basis, divine Principle, God, must be understood and obeyed. As to its action, the phrase "utilization of the power of Truth over error" indicates that there is something to be done, a transaction to be undertaken and carried through, a process to be worked out, a consummation to be reached. God must be acknowledged as All-in-all. The power of God must then be allowed to displace error, must operate for an orderly mental regeneration of thought and life. So is this Science practiced.
Christian Science reveals the eternal fact that God is forever maintaining the identity of the real man, His own likeness and image. This true likeness of God is the imperishable reality of everyone. The prayer which exalts the real man and refuses to acknowledge the frail and troubled mortal to be man, is spiritual understanding actively employed or "utilized," and this constitutes Christian Science treatment. Before the consistent devotion to the high purpose of effectual prayer, the belief in evil as real yields to spiritual discernment, and creation is understood as God knows it, including not an element of matter, but only spiritual man and the universe, indestructible and eternal.
