Chapter 93.
210 But as to the calumnious charges which you bring against us, saying that by us the wrath of the kings of the world is excited against you, so long as we do not teach them the lesson of holy Scripture, but rather suggest our own desire of war, I do not imagine that you are so absolutely deaf to the eloquence of the sacred books themselves as that you should not rather fear that they should be acquainted with it. But whether you so will or no, they gain entrance to the Church; and even if we hold our tongues, they give heed to the readers; and, to say nothing of the rest, they especially listen with the most marked attention to that very psalm which you quoted. For you said that we do not teach them, nor, so far as we can help it, allow them to become acquainted with the words of Scripture: "Be wise now therefore, O you kings; be instructed ye judges of the earth. Serve the Lord with fear and rejoice with trembling. Take hold of instruction lest the Lord be angry, etc. Believe that even this is sung, and that they hear it. But, at any rate, they hear what is written above in the same psalm, which you, unless I am mistaken, were only unwilling to pass over, for fear you should be understood to be afraid. They hear therefore this as well "The Lord has said unto me, You are my Son; this day have I begotten You. Ask of me, and I shall give You the heathen for Your inheritance, and the uttermost parts of the earth for Your possession." On hearing which, they cannot but marvel that some should be found to speak against this inheritance of Christ, endeavoring to reduce it to a little corner of the earth; and in their marvel they perhaps ask, on account of what they hear in what follows, "Serve the Lord with fear," wherein they can serve Him, in so far as they are kings. For all men ought to serve God—in one sense, in virtue of the condition common to them all, in that they are men; in another sense, in virtue of their several gifts, whereby this man has one function on the earth, and that man has another. For no man, as a private individual, could command that idols should be taken from the earth, which it was so long ago foretold should come to pass. Accordingly, when we take into consideration the social condition of the human race, we find that kings, in the very fact that they are kings, have a service which they can render to the Lord in a manner which is impossible for any who have not the power of kings.
211. When, therefore, they think over what you quote, they hear also what you yourself quoted concerning the three children, and hear it with circumstances of marvellous solemnity. For that same Scripture is most of all sung in the Church at a time when the very festal nature of the season excites additional fervor even in those who, during the rest of the year, are more given to be sluggish. What then do you think must be the feelings of Christian emperors, when they hear of the three children being cast into the burning fiery furnace because they were unwilling to consent to the wickedness of worshipping the image of the king, unless you suppose that they consider that the pious liberty of the saints cannot be overcome either by the power of kings, or by any enormity of punishment, and that they rejoice that they are not of the number of those kings who used to punish men that despised idols as though they were guilty of sacrilege? But, further, when they hear in what follows that the same king, terrified by the marvellous sight of, not only the three children, but the very flames performing service unto God, himself too began to serve God in fear, and to rejoice with reverence, and to lay hold of instruction, do they not understand that the reason that this was recorded, and set forth with such publicity, was that an example might be set both before the servants of God, to prevent them from committing sacrilege in obedience to kings, and before kings themselves, that they should show themselves religious by belief in God? Being willing, therefore, on their part, from the admonition of the very psalm which you yourself inserted in your writings, both to be wise, and to receive instruction, and to serve God with fear and to rejoice unto Him with reverence, and to lay hold of instruction, with what attention do they listen to what that king said afterwards! For he said that he would make a decree for all the people over whom he ruled, that whosoever should speak blasphemy against the God of Shadrach, Meshach, and Abednego should perish, and their house be utterly destroyed. And if they know that he made this decree that blasphemy should not be uttered against the God who tempered the force of the fire, and liberated the three children, they surely go on to consider what decrees they ought to make in their kingdom, that the same God who has granted remission of sins, and given freedom to the whole earth, should not be treated with scorn among the faithful in their realm.
212. See therefore, when Christian kings make any decree against you in defence of Catholic unity, that it be not the case that with your lips you are accusing them of being unlearned, as it were, in holy Scripture, while in your hearts you are grieving that they are so well acquainted with its teaching. For who could put up with the sacrilegious and hateful fallacy which you advance in the case of one and the same Daniel, to find fault with kings because he was cast into the den of lions, and to refuse praise to kings in that he was raised to exalted honor, seeing that, even when he was cast into the den of lions, the king himself was more inclined to believe that he would be safe than that he would be destroyed, and, in anxiety for him, refused to eat his food? And then do you dare to say to Christians, "What have you to do with the kings of the world?" because Daniel suffered persecution at a king's hands, and yet not look back upon the same Daniel faithfully interpreting dreams to kings, calling a king lord, receiving gifts and honors from a king? And so again do you dare, in the case of the aforesaid three children, to excite the flames of odium against kings, because, when they refused to worship the statue, they were cast into the flames, while at the same time you hold your tongue, and say nothing about their being thus extolled and honored by the king? Granted that the king was a persecutor when he cast Daniel into the lions' den; but when, on receiving him safely out again, in his joy and congratulations he cast in his enemies to be torn in pieces and devoured by the same lions, what was he then—a persecutor, or not? I call on you to answer me. For if he was, why did not Daniel himself resist him, as he might so easily have done in virtue of his great friendship for him, while yet you bid us restrain kings from persecuting men? But if he was not a persecutor, because he avenged with prompt justice the outrage committed against a holy man, what kind of vengeance, I would ask, must be exacted from kings for indignities offered to the sacraments of Christ, if the limbs of the prophet required such a vengeance because they were exposed to danger? Again, I acknowledge that the king, as indeed is manifest, was a persecutor when he cast the three children into the furnace because they refused to worship his image; but I ask whether he was still a persecutor when he set forth the decree that all who should blaspheme against the one true God should be destroyed, and their whole house laid waste? For if he was a persecutor, why do you answer Amen to the words of a persecutor? But if he was not a persecutor, why do you call those persecutors who deter you from the madness of blasphemy? For if they compel you to worship an idol, then they are like the impious king, and you are like the three children; but if they are preventing you from fighting against Christ, it is you who are impious if you attempt to do this. But what they may be if they forbid this with terrible threats, I do not presume to say. Do you find some other name for them, if you will not call them pious emperors.
