6. Because, therefore, for the security of particular men, and, by consequence, for the common peace, it is necessary that the right of using the sword for punishment be transferred to some man or council; that man or council is necessarily understood by right to have the supreme power in the city. For he that by right punisheth at his own discretion, by right compels all men to all things which he himself wills; than which a greater command cannot be imagined.
That the sword of war belongs to him also.
7. But in vain do they worship peace at home, who cannot defend themselves against foreigners; neither is it possible for them to protect themselves against foreigners, whose forces are not united. And therefore it is necessary for the preservation of particulars, that there be some one council or one man, who hath the right to arm, to gather together, to unite so many citizens, in all dangers and on all occasions, as shall be needful for common defence against the certain number and strength of the enemy; and again, as often as he shall find it expedient, to make peace with them. We must understand, therefore, that particular citizens have conveyed their whole right of war and peace unto some one man or council; and that this right, which we may call the sword of war, belongs to the same man or council, to whom the sword of justice belongs. For no man can by right compel citizens to take up arms and be at the expenses of war, but he who by right can punish him who doth not obey. Both swords therefore, as well this of war as that of justice, even by the constitution itself of a city and essentially do belong to the chief command.
The power of judicature belongs to him.
8. But because the right of the sword, is nothing else but to have power by right to use the sword at his own will, it follows, that the judgment of its right use pertains to the same party; for if the power of judging were in one, and the power of executing in another, nothing would be done. For in vain would he give judgment, who could not execute his commands; or, if he executed them by the power of another, he himself is not said to have the power of the sword, but that other, to whom he is only an officer. All judgment therefore, in a city, belongs to him who hath the swords; that is, to him who hath the supreme authority.
The legislative power is his also.
9. Furthermore, since it no less, nay, it much more conduceth to peace, to prevent brawls from arising than to appease them being risen; and that all controversies are bred from hence, that the opinions of men differ concerning meum and tuum, just and unjust, profitable and unprofitable, good and evil, honest and dishonest, and the like; which every man esteems according to his own judgment: it belongs to the same chief power to make some common rules for all men, and to declare them publicly, by which every man may know what may be called his, what another’s, what just, what unjust, what honest, what dishonest, what good, what evil; that is summarily, what is to be done, what to be avoided in our common course of life. But those rules and measures are usually called the civil laws, or the laws of the city, as being the commands of him who hath the supreme power in the city. And the civil laws (that we may define them) are nothing else but the commands of him who hath the chief authority in the city, for direction of the future actions of his citizens.
That the naming of magistrates and officers belongs to him also.
10. Furthermore, since the affairs of the city, both those of war and peace, cannot possibly be all administered by one man or one council without officers and subordinate magistrates; and that it appertaineth to peace and common defence, that they to whom it belongs justly to judge of controversies, to search into neighbouring councils, prudently to wage war, and on all hands warily to attend the benefit of the city, should also rightly exercise their offices; it is consonant to reason that they depend on, and be chosen by him who hath the chief command both in war and in peace.
The examination of doctrine belongs to him likewise.
