But what was the cause, O true-speaking Light? -- unto Thee lift I up my heart, let it not teach me vanities, dispel its darkness; and tell me, I beseech Thee, by our mother charity, tell me the reason, I beseech Thee, why after the mention of heaven, and of the earth invisible and without form, and darkness upon the deep, Thy Scripture should then at length mention Thy Spirit? Was it because it was meet that the knowledge of Him should be conveyed, as being "borne above"; and this could not be said, unless that were first mentioned, over which Thy Spirit may be understood to have been borne. For neither was He borne above the Father, nor the Son, nor could He rightly be said to be borne above, if He were borne over nothing. First then was that to be spoken of, over which He might be borne; and then He, whom it was meet not otherwise to be spoken of than as being borne. But wherefore was it not meet that the knowledge of Him should be conveyed otherwise, than as being borne above?
