I have to drive an hour one way to work every day. I started "reading" audio books with that "free time". It has been quite useful. Recently I came across a reading of the Didache. "The what?" you may ask. The Didache is a book written somewhere in the first or second century. For a long time it was up for consideration as Scripture. It was believed to be the Teaching of the Twelve Apostles. Eventually it was agreed that the book was an excellent book, but not inspired Scripture. So I was pleased to be able to download this admirable book containing good teachings from the early Church fathers.
The book seemed to be largely a lot of quotes from Scripture. You'll learn the basic rules of Christianity -- "First, you shall love God who made you; second, love your neighbor as yourself." You'll learn that "grave sins" are forbidden, like adultery, murder, fornication, and so on. (They specifically include pederasty in the list.) There are instructions regarding teachers, prophets, Christian assembly, and so on. Lots of the normal, good stuff. But, since this was written sometime prior to 200 AD, I was somewhat surprised at this instruction: "You shall not murder a child by abortion" (Didache, Ch 2).
Now, I've heard it said that this whole "pro-life" thing (expressed by opponents as "anti-abortion") is a modern-day phenomenon and didn't have any basis in historical Christianity. As it turns out, this isn't true at all. The Didache was quite clear. Clement of Alexandria (circa 150-215 AD) wrote against it in his Paedagogus (Book 2). Tertullian (circa 125-225 AD) specified, "In our case, murder being once for all forbidden, we may not destroy even the fetus in the womb, while as yet the human being derives blood from other parts of the body for its sustenance. To hinder a birth is merely a speedier man-killing; nor does it matter whether you take away a life that is born, or destroy one that is coming to the birth." (Apology Ch 9). With only a little searching you can find repeated references in the writings of early Church fathers who affirm that abortion is murder and, as such, forbidden.
Now, you can debate all you want about "when life begins" or some such, but what cannot be debated was the view of the early Church on the subject. They held that the fetus was human life and terminating a life when it wasn't yet born was still murder. Thus, it is "pro-life", not "anti-abortion".
