A Deeper understanding of the word I leads to a higher comprehension of God as infinite consciousness, or Mind, and of one's own real identity as Mind's reflection. On page 588 of "Science and Health with Key to the Scriptures" Mary Baker Eddy gives the definition of "I, or Ego," which reads in part: "Divine Principle; Spirit; Soul; incorporeal, unerring, immortal, and eternal Mind. There is but one I, or Us, but one divine Principle, or Mind, governing all existence." Life, Truth, Love, Mind, Soul, Spirit, Principle, the "one I, or Us," is God and is expressed by man and the universe.
Is it not plain that the use of I in connection with words that denote mortality, materiality, sin, disease, or death is unscientific? Yet we often hear the statements: "I am limited"; "I am diseased"; "I am afraid." But one may add: "I do not mean God or His reflection when I so speak. I mean my mortal self, my material body. I know that my spiritual selfhood is perfect; it is to this discordant body that I refer."
Here questions of great importance are in order, are there two kinds of man, one spiritual and one material? Or is man a mixture of Spirit and matter, of material sense and spiritual sense? What is man's true identity? Christian Science reveals that man is wholly spiritual, the reflection of God, the one I, or Ego. Therefore it follows that the material body or mortal self is not the truth of being. True selfhood is spiritual and entirely harmonious and perfect.
