Mary Baker Eddy states a fundamental teaching of Christian Science in these lines from "Science and Health with Key to the Scriptures" (p. 492): "For right reasoning there should be but one fact before the thought, namely, spiritual existence. In reality there is no other existence, since Life cannot be united to its unlikeness, mortality."
What a dynamic thought, that the actual, in fact, the only existence is spiritual and not material! How salutary are the inevitable conclusions that must be drawn from this eternal verity! Being the all and only, spiritual existence has no opposite, nothing to deny or resist its infinite, beneficent, frictionless being. Mortal existence, that which appears to be its opposite, is real only to its own self-deception. Spiritual existence knows no time or spatial limitations. It never began, cannot end, but forever is. It is forever unfolding good.
Being Mind, Spirit is omniscient. What it knows is its own nature of beauty, perfection, magnitude, and glory forever manifested in multitudinous forms of harmony and utility. Mind's knowing or consciousness is seen in its infinite self-expression, idea, or reflection. There is nothing limited, static, or temporary about spiritual existence, which expresses its divine, creative Principle. Being perfect, Spirit expresses itself in a perfect creation. Being infinite individuality, the one Ego or divine entity is reflected in an infinite idea—spiritual man and universe. Every individuality or identity, from the most minute to the infinite, is indivisibly one, illimitable, immortal, omnipresent, and eternal in expression.
