The Catechism of the Catholic Church is clear in its teaching that Catholics have a moral obligation to vote.
When Catholics have the opportunity to vote, the Church firmly believes that there is a “moral obligation” to participate in an election.
This teaching is explained in the Catechism of the Catholic Church.
Submission to authority and co-responsibility for the common good make it morally obligatory pay taxes, exercise the right to voteand to defend his country:
In addition, citizens are required to contribute to the common good of society.
It’s the duty of citizens contribute with the civil authorities for the good of society in a spirit of truth, justice, solidarity and freedom. The love and service of his country flow 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 role in the life of the political community.
At the same time, citizens must follow God first and not place human standards above those instituted by God.
The citizen is bound in conscience not to follow the directives of the civil authorities when they are contrary to the requirements of the moral order, to the fundamental rights of persons or to the teachings of the Gospel. refuse obedience to civil authorities, when their demands are contrary to those of an upright conscience, finds its justification in the distinction between serving God and serving the political community. “Render therefore to Caesar what is Caesar’s, and to God what is God’s.” “We must obey God rather than men.”
The Catechism does not tell us “how” to vote, but it instructs us that we must vote, participate in any election that is held in our country.
