Why does Herod make this enquiry, seeing he believed not the Scriptures? Or if he did believe, how could he hope to be able to kill Him whom the Scriptures declared should be King? The Devil instigated Herod; who believed that Scripture lies not. Such is the faith of devils, who are not permitted to have perfect belief, even of that which they do believe. That they do believe, it is the force of truth constrains them; that they do not believe, it is that they are blinded by the enemy. If they had perfect faith, they would live as about to depart from this world soon, not as to possess it for ever.
