By the Christian Scientist, the evenings and mornings of the first chapter of Genesis are not taken as records of material darkness and dawn, but as constantly unfolding spiritual views of Truth, advancing states of consciousness.
As Mary Baker Eddy says in "Science and Health with Key to the Scriptures" (P. 509), "The periods of spiritual ascension are the days and seasons of Mind's creation, in which beauty, sublimity, purity, and holiness—yea, the divine nature—appear in man and the universe never to disappear."
The order of creation in the first chapter of Genesis may be likened in individual consciousness to orderly spiritual unfoldment. Is not the earth "without form, and void," is not darkness "upon the face of the deep" to us until, through Christian Science, we begin to get some spiritual light in which God, substance, hope, and reality commence to appear? Is not that dawning mental light our "first day" of creation or revelation?
