I don’t see pro choice equating to being personally in favor of, or pro abortion when in a nation of many views and beliefs. But when seeking our own religious liberty, regardless of what our own religion or faith is, I can see a conflict in telling a woman whose faith teaches something different about abortion, that she can not make the choice that her own faith allows. Just as a Catholic woman has the right to follow her faith and to not choose an abortion based on the dictates of her faith.
But not everyone has the same faith in the CC and ECFs nor in their interpretations as do faithful Catholics. Nor do all Christians believe that our human understanding, finite as it is, must remain stagnant and can not grow and evolve over time, as we walk by faith not by sight in seeking to understand an infinite God along the journey.
There are many Christians who believe all life is sacred and that equally includes the woman’s and her family members’ lives. And who believe God has given us the responsibility to make decisions which reflect this when conflicting realities are present and lives are affected. And that these are not always easy black and white decisions. And that therefore a woman should have the legal right to make her decision based on the dictates of her own faith. And that women of limited means should be able to receive public funding to assure they have the same legal right to make their decisions on the issue following the dictates of their own faith as well.
Now of course I understand you do not consider it Christian based on the dictates of your faith. But many people in good faith who do not share yours, do consider it so. They understand there are many religious and theological perspectives on when life and personhood begin and respect this diversity. And believe this is not a pro abortion position but a pro-faith, pro-family, pro-woman position. There simply is no other issue comparable today. Which is why comparisons to slavery for instance fall short. Because while there may someday come a time when there is, there is today simply no consensus on the abortion issue that there is on other issues. Far from it even among people of faith and good will.
