The duties of citizens
It is the duty of citizens to contribute along with the civil authorities to the good of society in a spirit of truth, justice, solidarity, and freedom. The love and service of one's country follow from the duty of gratitude and belong to the order of charity. Submission to legitimate authorities and service of the common good require citizens to fulfill their roles in the life of the political community.
