And He here calls the devil “the wicked one,” commanding us to wage against him a war that knows no truce, and implying that he is not such by nature. For wickednessis not of those things that are from nature, but of them that are added by our own choice. And he is so called pre-eminently, by reason of the excess of his wickedness, and because he, in no respect injured by us, wages against us implacable war. Wherefore neither said He, “deliver us from the wicked ones,” but, “from the wicked one;” instructing us in no case to entertain displeasure against our neighbors, for what wrongs soever we may suffer at their hands, but to transfer our enmity from these to him, as being himself the cause of all our wrongs.
