CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2254–2257

2254 Public authority is obliged to respect the fundamental rights of the human person and the conditions for the exercise of his freedom.
2255 It is the duty of citizens to work with civil authority for building up society in a spirit of truth, justice, solidarity, and freedom.
2256 Citizens are obliged in conscience not to follow the directives of civil authorities when they are contrary to the demands of the moral order. "We must obey God rather than men" (Acts 5:29).
2257 Every society's judgments and conduct reflect a vision of man and his destiny. Without the light the Gospel sheds on God and man, societies easily become totalitarian.
