No Catholic can responsibly take a “pro-choice” stand when the “choice” in question involves the taking of innocent human life.
Resolution on Abortion (1989)
We urge those Catholic officials who choose to depart from Church teaching on the inviolability of human life in their public life to consider the consequences for their own spiritual well being, as well as the scandal they risk by leading others into serious sin. We call on them to reflect on the grave contradiction of assuming public roles and presenting themselves as credible Catholics when their actions on fundamental issues of human life are not in agreement with Church teaching. No public official, especially one claiming to be a faithful and serious Catholic, can responsibly advocate for or actively support direct attacks on innocent human life. [N]o appeal to policy, procedure, majority will or pluralism ever excuses a public official from defending life to the greatest extent possible. As is true of leaders in all walks of life, no political leader can evade accountability for his or her exercise of power (Evangelium Vitae, 73-4). Those who justify their inaction on the grounds that abortion is the law of the land need to recognize that there is a higher law, the law of God. No human law can validly contradict the Commandment: “Thou shalt not kill.”
