So, no, Christianity's “ferocious opposition to abortion” is not “new.” Yes, there have been historical debates over the practice — and debates continue today — but here is a fundamental fact of theological life: The more a church defends abortion, the less likely it is to be theologically orthodox. Embrace of abortion rights is typically part and parcel of a theological drift that rejects much of the rest of the faith. Just ask the Presbyterian Church (USA). Just ask the United Churches of Christ. In fact, many of the pro-abortion denominations are no longer recognizably Christian in any historic, theological sense.
