The history of Catholic teaching on abortion isn’t as clear cut as you think
Its position has hardly been “unchangeable” throughout the past two millennia.
Even though 56 percent of U.S. Catholics believe that abortion should be legal in most or all cases, it’s a commonly held belief that being “pro-choice” is incompatible with being Catholic. That’s not surprising, given the Catholic Church’s stance on abortion seems pretty clear cut: abortion is a murder. The Catechism of the Catholic Church even says, “Since the first century, the Church has affirmed the moral evil of every procured abortion. This teaching has not changed and remains unchangeable.”
That’s not exactly true, though.
