On most issues that come before voters or legislators, a Catholic can take one side or the other and not act contrary to his faith. Most matters do not have a "Catholic position."
But some issues are so key, so elemental, that only one position accords with the teaching of the Christian gospel. No one endorsing the wrong side of these subjects can be said to act in accord with the Church's moral norms.
This voter's guide identifies five "non-negotiable" issues and helps you narrow down the list of acceptable candidates, whether they are running for national, state, or local offices.
Candidates who endorse or promote any of the five non-negotiables should be considered to have disqualified themselves from holding public office, and you should not vote for them. You should make your choice from among the remaining candidates.
YOUR ROLE AS A CATHOLIC VOTER
Catholics have a moral obligation to promote the common good through the exercise of their voting privileges (cf. CCC 2240). It is not just civil authorities who have responsibility for a country. "Service of the common good require citizens to fulfill their roles in the life of the political community" (CCC 2239). This means citizens should participate in the political process at the ballot box.
But voting cannot be arbitrary. "A well-formed Christian conscience does not permit one to vote for a political program or an individual law that contradicts the fundamental contents of faith and morals" (CPL 4).
Some things always are wrong, and no one may vote in favor of them, directly or indirectly. Citizens vote in favor of these evils if they vote in favor of candidates who propose to advance them. Thus, Catholics should not vote for anyone who intends to push programs or laws that are intrinsically evil.
THE FIVE NON-NEGOTIABLE ISSUES
These five issues are called non-negotiable because they concern actions that are always morally wrong and must never be promoted by the law. It is a serious sin to endorse or promote any of these actions, and no candidate who really wants to advance the common good will support any of the five non-negotiables.
1. Abortion
The Church teaches that, regarding a law permitting abortions, it is "never licit to obey it, or to take part in a propaganda campaign in favor of such a law, or to vote for it" (EV 73). Abortion is the intentional and direct killing of an innocent human being, and therefore it is a form of homicide.
The child is always an innocent party, and no law may permit the taking of his life. Even when a child is conceived through rape or incest, the fault is not the child's, who should not suffer death for others' sins.
