Matt. II. 16.
“Then Herod, when he saw that he was mocked of the wise men, was exceeding angry.”
Yet surely it was a case not for anger, but for fear and awe: he ought to have perceived that he was attempting impossible things. But he is not refrained. For when a soul is insensible and incurable, it yields to none of the medicines given by God. See for example this man following up his former efforts, and adding many murders to one, and hurried down the steep any whither. For driven wild by this anger, and envy, as by some demon, he takes account of nothing, but rages even against nature herself, and his anger against the wise men who had mocked him he vents upon the children that had done no wrong: venturing then in Palestine upon a deed akin to the things that had been done in Egypt. For he “sent forth,” it is said, “and slew all the children that were in Bethlehem, and in all the coasts thereof, from two years old and under, according to the time which he had diligently inquired of the wise men.”
Here attend to me carefully. Because many things are uttered by many very idly touching these children, and the course of events is charged with injustice, and some of these express their perplexity about it in a more moderate way, others with more of audaciousness and frenzy. In order then that we may free these of their madness and those of their perplexity, suffer us to discourse a little upon this topic. Plainly, then, if this be their charge, that the children were left to be slain, they should find fault likewise with the slaughter of the soldiers that kept Peter. For as here, when the young child had fled, other children are massacred in the place of Him who was sought; even so then, too, Peter having been delivered from his prison and chains by the angel, one of like name with this tyrant, and like temper too, when he had sought him, and found him not, slew instead of him the soldiers that kept him.
“But what is this?” it may be said; “why this is not a solution, but an enhancement of our difficulty.” I know it too, and for this intent I bring forward all such cases, that to all I may adduce one and the same solution. What then is the solution of these things? Or what fair account of them can we give? That Christ was not the cause of their slaughter, but the king's cruelty; as indeed neither was Peter to those others, but the madness of Herod. For if he had seen the wall broken through, or the doors overthrown, he might, perhaps, have had ground to accuse the soldiers that kept the apostle, of neglect; but now when all things continued in due form, and the doors were thrown wide open, and the chains fastened to the hands of them that kept him (for in fact they were bound unto him), he might have inferred from these things (that is, if he had been strictly doing a judge's office on the matters before him), that the event was not of human power or craft, but of some divine and wonder-working power; he might have adored the doer of these things, instead of waging war with the sentinels. For God had so done all that He did, that so far from exposing the keepers, He was by their means leading the king unto the truth. But if he proved senseless, what signifies to the skillful Physician of Souls, managing all things to do good, the insubordination of him that is diseased?
And just this one may say in the present case likewise. For, wherefore are you angry, O Herod, at being mocked of the wise men? Did you not know that the birth was divine? Did you not summon the chief priests? Did you not gather together the scribes? Did not they, being called, bring the prophet also with them into your court of judgment, proclaiming these things beforehand from of old? Did you not see how the old things agreed with the new? Did you not hear that a star also ministered to these men? Did you not reverence the zeal of the barbarians? Did you not marvel at their boldness? Were you not horror-struck at the truth of the prophet? Did you not from the former things perceive the very last also? Wherefore did you not reason with yourself from all these things, that this event was not of the craft of the wise men, but of a Divine Power, duly dispensing all things? And even if you were deceived by the wise men, what is that to the young children, who have done no wrong?
