Under the marginal heading "Indestructible relationship" Mary Baker Eddy writes in the textbook, "Science and Health with Key to the Scriptures" (p. 470): "God is the creator of man, and, the divine Principle of man remaining perfect, the divine idea or reflection, man, remains perfect. Man is the expression of God's being." God being perfect Mind, perfect Love, what heavenly wisdom, what loving-kindness, God's man naturally expresses! Thus to manifest God more fully humanity must learn more of the divine nature.
Our textbook gives us a complete definition of Deity. In the seven synonyms for God used by Mrs. Eddy—Principle, Mind, Soul, Spirit, Life, Truth, Love—we discover the nature of Deity and see Him as the divine I, or Us, the one Father-Mother God, who declared (Gen. 1:26), "Let us make man in our image, after our likeness." It is clear that man is never God and that he did not assist God in creating His universe, but that man is forever essential to God as His reflection, His expression, the witness to the eternal goodness of his creator. This enlightening concept of God and of man's relationship to Him needs to be grasped in order that humanity succeed in its search for God, good.
The oneness of God is discerned in the perfect unity of all His divine qualities. The oneness, or unity, of God and man is seen in man's perfect reflection of God's nature. Because God is infinite individuality, man, God's reflection, is forever individual. The false belief that man is God or that man can be absorbed in Him, Christian Science destroys.
