The law of Christ therefore concerning killing, and consequently all manner of hurt done to any man, and what penalties are to be set, commands us to obey the city only. In like manner, by that precept, _Thou shalt not commit adultery_, all manner of copulation is not forbidden; but only that of lying with _another man’s wife_. But the judgment, which is another man’s wife, belongs to the city; and is to be determined by the rules which the city prescribes. This precept therefore commands both male and female to keep that faith entire, which they have mutually given according to the statutes of the city. So also by the precept, _thou shalt not steal_, all manner of invasion or secret surreption is not forbidden; but of _another man’s only_. The subject therefore is commanded this only, that he invade not nor take away aught which the city prohibits to be invaded or taken away; and universally, not to call anything _murder_, _adultery_, or _theft_, but what is done contrary to the civil laws. Lastly, seeing Christ hath commanded us to _honour our parents_, and hath not prescribed with what rites, what appellations, and what manner of obedience they are to be honoured; it is to be supposed that they are to be honoured with the will indeed, and inwardly, as kings and lords over their children, but outwardly, not beyond the city’s permission, which shall assign to every man, as all things else, so also _his honour_. But since the nature of justice consists in this, that every man have his own given him; it is manifest, that it also belongs to a Christian city to determine what is justice, what injustice, or a sin against justice. Now what belongs to a city, that must be judged to belong to him or them who have the sovereign power of the city. [Sidenote: It belongs to civil authority, to define what conduces to the peace and safety of the city.] 11. Moreover, because our Saviour hath not showed subjects any other laws for the government of a city, beside those of nature, that is to say, beside the command of obedience; no subject can privately determine who is a public friend, who an enemy, when war, when peace, when truce is to be made, nor yet what subjects, what authority and of what men, are commodious or prejudicial to the safety of the commonweal. These and all like matters therefore are to be learned, if need be, from the city, that is to say, from the sovereign powers. [Sidenote: It belongs to the civil authority, to judge, when need requires, what definitions and what inferences are true.]
