Now, why do I think this matters. Let’s say you are trying to discuss abortion with secular progressives. And you assert, ‘abortion is murder, it always has been murder, end of story…’ Then they start pulling out quotes, Pope Innocent III specifically ruling that early abortion is not murder, St. Thomas Aquinas arguing the correctness of the doctrine, Pope Gregory the XIV reaffirming the teaching centuries later.
Next you say, ‘well, maybe we believed that once, but not now’, then they pull out documents from the Congregation of the Doctrine of the Faith on procurred abortion and respect for fetal life and point to the actual text and footnotes. And, behold, the same language is there.
So you say, 'well, I’m not up on the whole history of this, but I know what is right, just look at our earliest Christain writings". So they pull out Tertullian, who did have views on abortion remarkably close to our modern ones (although for heretical reasons), and show you that right between two very popular quotes on pro-life websites in another paragragh, one that describes a primitive ‘partial-birth’ abortion in gruesome detail and describes it as a “necessary cruelty”, the moral correctness even the greatest proponents of life would not argue with.
