In the current issue of America , ” A Sexual Revolution : One woman’s journey from pro-choice atheist to pro-life Catholic.”
The Theology of the Body seems key. A bit from the article:
Growing up in secular middle-class America, I understood sex as something disconnected from the idea of creating life. During my entire childhood I did not know anyone who had a baby sibling; and to the extent that neighborhood parents ever talked about pregnancy, it was to say they were glad they were “done.” In high school sex education class, we learned not that sex creates babies, but that unprotected sex creates babies. Even recently, before our marriage was blessed in the Catholic Church, my husband and I took a course about building good marriages. It was a video series by a nondenominational Christian group, and the segment called “Good Sex” did not mention children once. In all the talk about bonding and back rubs and intimacy and staying in shape, the closest the videos came to connecting sex to the creation of life was a brief note that couples should discuss the topic of contraception.
All my life, the message I had heard loud and clear was that sex was for pleasure and bonding, that its potential for creating life was purely tangential, almost to the point of being forgotten. This mind-set became the foundation of my views on abortion. Because I saw sex as being by default closed to the possibility of life, I thought of unplanned pregnancies as akin to being struck by lightning while walking down the streetsomething totally unpredictable and undeserved that happened to people living normal lives.
My pro-choice views (and I imagine those of many others) were motivated by loving concern: I just did not want women to have to suffer, to have to devalue themselves by dealing with unwanted pregnancies. Since it was an inherent part of my worldview that everyone except people with “hang-ups” eventually has sex, and that sex is, under normal circumstances, only about the relationship between the two people involved, I was lured into one of the oldest, biggest, most tempting lies in human history: the enemy is not human. Babies had become the enemy because of their tendency to pop up and ruin everything; and just as societies are tempted to dehumanize their fellow human beings on the other side of the line in wartime, so had I, and we as a society, dehumanized what we saw as the enemy of sex.
As I was reading up on the Catholic Church’s understanding of sex, marriage and contraception, everything changed. I had always assumed that Catholic teachings against birth control were outdated notions, even a thinly disguised attempt to oppress the faithful. What I found, however, was that these teachings expressed a fundamentally different understanding of sex. And once I discovered this, I never saw the world the same way again.
