Rom 13:4

“As therefore the devil lied at the beginning, so did he also in the end, when he said, "All these are delivered unto me, and to whomsoever I will I give them." For it is not he who has appointed the kingdoms of this world, but God; for "the heart of the king is in the hand of God." And the Word also says by Solomon, "By me kings do reign, and princes administer justice. By me chiefs are raised up, and by me kings rule the earth." Paul the apostle also says upon this same subject: "Be ye subject to all the higher powers; for there is no power but of God: now those which are have been ordained of God." And again, in reference to them he says, "For he beareth not the sword in vain; for he is the minister of God, the avenger for wrath to him who does evil." Now, that he spake these words, not in regard to angelical powers, nor of invisible rulers-as some venture to expound the passage-but of those of actual human authorities, [he shows when] he says, "For this cause pay ye tribute also: for they are God's ministers, doing service for this very thing." This also the Lord confirmed, when He did not do what He was tempted to by the devil; but He gave directions that tribute should be paid to the tax-gatherers for Himself and Peter; because "they are the ministers of God, serving for this very thing."”

“For since man, by departing from God, reached such a pitch of fury as even to look upon his brother as his enemy, and engaged without fear in every kind of restless conduct, and murder, and avarice; God imposed upon mankind the fear of man, as they did not acknowledge the fear of God, in order that, being subjected to the authority of men, and kept under restraint by their laws, they might attain to some degree of justice, and exercise mutual forbearance through dread of the sword suspended full in their view, as the apostle says: "For he beareth not the sword in vain; for he is the minister of God, the avenger for wrath upon him who does evil." And for this reason too, magistrates themselves, having laws as a clothing of righteousness whenever they act in a just and legitimate manner, shall not be called in question for their conduct, nor be liable to punishment. But whatsoever they do to the subversion of justice, iniquitously, and impiously, and illegally, and tyrannically, in these things shall they also perish; for the just judgment of God comes equally upon all, and in no case is defective. Earthly rule, therefore, has been appointed by God for the benefit of nations, and not by the devil, who is never at rest at all, nay, who does not love to see even nations conducting themselves after a quiet manner, so that under the fear of human rule, men may not eat each other up like fishes; but that, by means of the establishment of laws, they may keep down an excess of wickedness among the nations. And considered from this point of view, those who exact tribute from us are "God's ministers, serving for this very purpose."”

“Who would not prefer the justice of the world, which, as the apostle himself testifies, "beareth not the sword in vain," and which is an institute of religion when it severely avenges in defence of human life? When we contemplate, too, the penalties awarded to other crimes-gibbets, and holocausts, and sacks, and harpoons, and precipices-who would not think it better to receive his sentence in the courts of Pythagoras and Empedocles? For even the wretches whom they will send into the bodies of asses and mules to be punished by drudgery and slavery, how will they congratulate themselves on the mild labour of the mill and the water-wheel, when they recollect the mines, and the convict-gangs, and the public works, and even the prisons and black-holes, terrible in their idle, do-nothing routine? Then, again, in the case of those who, after a course of integrity, have surrendered their life to the Judge, I likewise look for rewards, but I rather discover punishments.”

“In what sense is a judge in this world the servant of God?… It seems to me that this question is answered by that passage in the Acts of the Apostles where the decision was taken to impose only certain ritual obligations on Gentile believers. They were told to abstain from eating what had been sacrificed to idols, from blood and from fornication, but nothing was said about murder, adultery, theft, homosexuality or other crimes which are punished by both divine and human laws. Now if what was explicitly forbidden to the Gentiles was all they had to do, then it would seem as if these other things were all right. But look at how the Holy Spirit has organized everything. Because these other crimes are already punished by secular laws, it seemed superfluous to add a divine prohibition as well. All that he decreed concerned matters which seemed right from the divine point of view but which were not covered by human laws. It is in this way that a human judge acts as a servant of God. For God wants these crimes to be punished by human judges and not by representatives of the church.”

“"For he is the minister of God to thee for good." So far is he from terrifying thee, he says, that he even praises thee: so far from being a hindrance to thee, that he even works with thee. When then thou hast his praise and his succor, how is it that thou art not in subjection to him? For he maketh virtue easier for thee in other ways also, by chastising the wicked, by benefiting and honoring the good, and by working together with the will of God. Whence too he has even given him the name of "Minister." And consider: I give you counsel to be sober-minded, and he, by the laws, speaks the same language. I exhort you not to be rapacious and grasping. And he sits in judgment in such cases, and so is a worker together with us, and an assistant to us, and has been commissioned by God for this end. Hence there are both reasons for reverencing him, both because he was commissioned by God, and because it was for such an object. "But if thou do that which is evil, be afraid." It is not then the ruler that maketh the fear, but our own wickedness. "For he beareth not the sword in vain." You see how he hath furnished him with arms, and set him on guard like a soldier, for a terror to those that commit sin. "For he is the minister of God to execute wrath, a revenger upon him that doeth evil." Now lest you should start off at hearing again of punishment, and vengeance, and a sword, he says again that it is God's law he is carrying out. For what if he does not know it himself? yet it is God that hath so shaped things. If then, whether in punishing, or in honoring, he be a Minister, in avenging virtue's cause, in driving vice away, as God willeth, why be captious against him, when he is the cause of so many good doings, and paves the way for thine too? since there are many who first practised virtue through the fear of God. For there are a duller sort, whom things to come have not such a hold upon as things present. He then who by fear and rewards gives the soul of the majority a preparatory turn towards its becoming more suited for the word of doctrine, is with good reason called "the Minister of God."”

“He, it says, assists the will of God. For example: God counsels you to be chaste, and the ruler prescribes the same through laws. God exhorts you not to be covetous and a thief, and the ruler is appointed as judge over the same. Consequently, he is our helper in good works, if we submit ourselves to him. So then, it is not the ruler who produces fear in us, but our own vices, on account of which the ruler's sword also exists, that is, the authority to punish. The ruler, he says, does not gird himself with the sword in vain, but in order to punish the wicked. When a ruler praises virtue, he fulfills the will of God; and when he puts the sword to use, he is a servant of God, defending virtue and driving away vice. Many do good not so much out of the fear of God as out of fear of rulers. Therefore, when a ruler defends virtue and punishes vice, he is a servant of God.”

“It is necessary to have a just intention, so that the man who is the minister of the law slays a man by law, not from the desire for vengeance, but from the love of justice. Whence the Apostle to the Romans, speaking to rulers, says that "the ruler does not bear the sword without cause. For he is the minister of God, an avenger unto wrath against him who does evil."”

“Fourth, he assigns the reason, saying: for he is God's minister to you for good. This is clear in regard to the proper order of rulers. For they are under the authority of God, the supreme ruler, as his ministers: because as ministers of his kingdom, you did not rule rightly (Wis 6:4). But the ruler and the ministers work for the same end: like the magistrate of the people, so are his officials (Sir 10:2). Therefore, just as God works for the good of those who do good, so also do rulers, if they perform their office properly. Furthermore, even wicked rulers are God's ministers for inflicting punishments according to God's plan; although this is not their intention: ah, Assyria, the rod of my anger, the staff of my fury . . . but he does not so intend (Isa 10:5). Behold I will send, and take all the kindreds of the north, says the Lord, and Nabuchodonosor the king of Babylon my servant: and I will bring them against this land, and against the inhabitants thereof, and against all the nations that are round about it (Jer 25:9). And also because such wicked rulers sometimes afflict good men, God permitting, who profit thereby; for we know that in everything God works for the good with those who love him (Rom 8:28). Then when he says but if you do evil, he shows the necessity of this teaching. For it has been stated that if you do right, you will not fear authority; but if you do evil, be afraid, because you have reason to fear: destruction to evildoers (Prov 10:29); wickedness is a cowardly thing, condemned by its own testimony (Wis 17:11). Second, he assigns the reason, saying: for he carries not the sword in vain. He uses language in keeping with the practice of rulers who carried the instruments of punishment as signs of their power; for example, a bundle of rods for whipping, and axes or swords for killing: be afraid of the sword, for wrath brings the punishment of the sword (Job 19:29). Third, he explains the reason, saying: he carries, I say, the sword, because he is God's minister, an avenger to execute his wrath, i.e., God's wrath, i.e., his just judgment, upon him that does evil: behold, I will gather together all your lovers . . . and I will judge you as adulteresses . . . and I will deliver you into their hands (Ezek 16:37ff.). Those who do evil are an abomination to kings, for the throne is established by justice (Prov 16:12). From this it is clear that it is not only lawful but meritorious for rulers to execute vengeance on the wicked, when it is done out of zeal for justice. Hence: and it shall be wages for his army, and for the service that he has done me against it (Ezek 29:19ff.).”
