The fifth creative formation was the adjustment of the cosmical relations of the heavenly bodies, and the establishment of such atmospheric conditions as rendered the sun and moon the _luminaries_, or light-bearers, to the earth. "And God said, Let there be luminaries in the expanse of heaven to divide the day and night." What these adjustments and collocations were, we are not able to say. The ultimate cause of the sun's luminosity is yet an unsolved problem. No explanation thus far offered has been accepted as adequate by the majority of scientific men. The statement of Genesis, which ascribes "the appointment of the sun and moon to be light-bearers to the earth" to a distinct creative formation of some kind, is not, therefore, invalidated by science. The sixth creative formation was the _material organisms_ of the varied species of "living souls" which people the _waters_; the seventh, of those which people the _air_; the eighth, of those which people the _land_. The final creative formation was the body of man, into which God breathed the breath of _lives_, and in consequence of which he became not merely a living soul, but a spiritual personality, a _spirit-being_. The question whether the material organisms in which the varied species of "living souls" are embodied were each the product of a special creation, or whether later and higher organisms were derived from prior and lower organisms by "filiation," so that "new species are new births," is of little consequence to the interpretation of Genesis. The essential element of species is a _spiritual_ entity. Specific existence is a positive existence, an immaterial existence,[212] "a soul of life." "It is not," says Dr. Winchell, "a primordial organic form: _it is the life embodied within that form_--the principle which rules its existence, moulds its features, determines its instincts, and conserves its specific and individual identity. It is the principle embodied in the ovum--often a mere microscopic organism--which unfailingly holds fast to the specific type, and through all embryonic and immature existence guides the progress of development in one direction, toward one end. Here is more than matter: here is a power which controls matter, controls chemistry--manifests its superiority to body, and asserts its dignity as spirit." The establishment of a genetic connection from the lowest to the highest material organism would not decide the question as to "the origin of species." The origin of species lies back of all material organisms. The species is a "spiritual germ," which acts upon and fashions the material elements, and through them expresses its own characteristics. That therefore which constitutes man a distinct species is not to be sought in anatomical peculiarities, but in spiritual attributes. It is the image of God and the inspiration of God which lifts man out of mere animal nature and makes him a _peculiar
