XXXVIII. To the Jews.
Evil always, and recalcitrant, with a stiff neck you wish not that you should be overcome; thus you will be heirs. Isaiah said that you were of hardened heart. You look upon the law which Moses in wrath dashed to pieces; and the same Lord gave to him a second law. In that he placed his hope; but you, half healed, reject it, and therefore you shall not be worthy of the kingdom of heaven.
