In order to show that he had read the book of Genesis, Celsus rejects the story of the dove, although unable to adduce any reason which might prove it to be a fiction. In the next place, as his habit is, in order to put the narrative in a more ridiculous light, he converts the “raven” into a “crow,” and imagines that Moses so wrote, having recklessly altered the accounts related of the Grecian Deucalion; unless perhaps he regards the narrative as not having proceeded from Moses, but from several individuals, as appears from his employing the plural number in the expressions, “falsifying and recklessly altering the story of Deucalion,” as well as from the words, “For they did not expect, I suppose, that these things would come to light.”
But how should they, who gave their Scriptures to the whole nation, not expect that they would come to light, and who predicted, moreover, that this religion should be proclaimed to all nations? Jesus declared, “The kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof;” and in uttering these words to the Jews, what other meaning did He intend to convey than this, viz., that He Himself should, through his divine power, bring forth into light the whole of the Jewish Scriptures, which contain the mysteries of the kingdom of God?
If, then, they peruse the Theogonies of the Greeks, and the stories about the twelve gods, they impart to them an air of dignity, by investing them with an allegorical signification; but when they wish to throw contempt upon our biblical narratives, they assert that they are fables, clumsily invented for infant children!
