Here’s the original Salon article. Just out of this world!

The worst part of her piece is the anti-historical twaddle about abortion being hunky-dory in the Catholic Church until 1869 and various saints and scholars disputing fetal ensoulment. We’ve heard this same revisionist nonsense from Nancy Pelosi et al., and the fact that this sort of urban legend keeps popping up shows how poorly the Catholic Church is doing its job in getting the truth out there about its own teachings.
1) Your belief that the Church's ethic against abortion dates back only to the 1800's, is incorrect. It dates back to the Didache, the 1st century catechism which appeared almost contemporaneously with the completion of the NT canon. Its roots? The realization that God named and called the prophets "from their mothers' wombs," and the wonderful passage from Luke where the Holy Spirit is poured upon a woman (!)(Elizabeth) and her unborn son (!)(John the Baptist --- a.k.a. John the Fetus). The point: both are persons in the full sense of the word.
2) Upon contact with Aristotelian philosophy, there was debate over whether abortion was homicide or "merely" closely akin to homicide. This legalistic/ theoretical distinction arose from a total ignorance of the human genome. However, abortion was in *any* case ethically offensive, whether it was the killing of a "formed" and "quickened" human or "merely" the destruction of a becoming- human.
3) Your account of the death of Savita Halappanavar is inaccurate. She died because of series of malpractice events, her blood sepsis not being diagnosed and treated in a timely way. Not caused by denial of termination.
