| 1897 "Human society can be neither well-ordered nor prosperous unless it has some people invested with legitimate authority to preserve its institutions and to devote themselves as far as is necessary to work and care for the good of all."
By "authority" one means the quality by virtue of which persons or institutions make laws and give orders to men and expect obedience from them. |
| 1898 Every human community needs an authority to govern it. The foundation of such authority lies in human nature. It is necessary for the unity of the state. Its role is to ensure as far as possible the common good of the society. |
| 1899 The authority required by the moral order derives from God: "Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore he who resists the authorities resists what God has appointed, and those who resist will incur judgment." |
| 1900 The duty of obedience requires all to give due honor to authority and to treat those who are charged to exercise it with respect, and, insofar as it is deserved, with gratitude and good-will.
|
| 1901 If authority belongs to the order established by God, "the choice of the political regime and the appointment of rulers are left to the free decision of the citizens."
The diversity of political regimes is morally acceptable, provided they serve the legitimate good of the communities that adopt them. Regimes whose nature is contrary to the natural law, to the public order, and to the fundamental rights of persons cannot achieve the common good of the nations on which they have been imposed. |
