37 Nevertheless no one, who has a correct idea of biblical inspiration, will be surprised to find, even in the Sacred Writers, as in other ancient authors, certain fixed ways of expounding and narrating, certain definite idioms, especially of a kind peculiar to the Semitic tongues, so-called approximations, and certain hyperbolical modes of expression, nay, at times, even paradoxical, which even help to impress the ideas more deeply on the mind. For of the modes of expression which, among ancient peoples, and especially those of the East, human language used to express its thought, none is excluded from the Sacred Books, provided the way of speaking adopted in no wise contradicts the holiness and truth of God, as, with his customary wisdom, the Angelic Doctor already observed in these words: "In Scripture divine things are presented to us in the manner which is in common use amongst men." For as the substantial Word of God became like to men in all things, "except sin," so the words of God, expressed in human language, are made like to human speech in every respect, except error. In this consists that "condescension" of the God of providence, which St. John Chrysostom extolled with the highest praise and repeatedly declared to be found in the Sacred Books.
