Faithful Citizenship states clearly:
Above all, the common outcry, which is justly made on behalf of human rights—for, example the right to health, to home, to work, to family, to culture—is false and illusory if the right to life, the most basic fundamental right and the condition for all other personal rights, is not defended with maximum determination. (Christifideles Laici, no. 38)
Labels, however, can be deceiving and overlook too many factors. There are an entire range of life and dignity issues to consider in any voting decision. Elected officials and candidates will fall somewhere on a spectrum between the two extremes and voters will want to take that into account. It is also good to consider not only expressed stances but also the ability of a candidate to influence an issue, his or her integrity and character and what concrete actions he or she may have taken with regard to important issues.
As Richard Doerflinger, former Associate Director of Pro-Life Activities at the U.S. Conference of Catholic Bishops has pointed out: “There are also some theological and pastoral arguments for not linking the Church's moral authority to our highly fallible expectations regarding the performance of particular individuals. The list of disappointments in this regard throughout history would be a long one.”
“As Catholics we are not single-issue voters” (USCCB, Forming Consciences for Faithful Citizenship, no. 42). The Catholic faith is not built upon one single element just as our individual journey to salvation is not made on one single act.
