It's a message that many of my fellow parishioners would likely not want to hear, but as St. Paul wrote two millennia ago to the Galatians:
"Am I now seeking human approval or God's approval? Or am I trying to please people? If I were still pleasing people, I would not be a servant of God." (Galatians 1:10, NRSV Cath. Ed.)
Despite House Speaker Pelosi's recent assertions to the contrary, the Catholic Church has had a clear and consistent record of opposing abortion dating back to the 1st century A.D. teachings of the Church Fathers in the Didache.
Pope Benedict XVI, back when he was Cardinal Ratzinger, wrote that a Catholic can vote for a pro-abortion candidate for other reasons only when those reasons are "proportionate". Under Catholic teaching, the taking of innocent life is considered the most serious sin prevalent in society today. For that reason, none of the commonly suggested reasons for voting for a pro-abortion candidate like Sen. Obama such as peace, health care, poverty reduction, etc. are considered proportionate.
