Well,
Christianity Today has an article that gives more perspective on Jonathan Dudley’s historical narrative. The whole thing is worth a look because it shows that evangelical views in the 1960s and 1970s were complex and not so easily simplified as “evangelicals used to be pro-choice.”
But he’s mischaracterized Bruce Waltke’s views. Waltke was writing about Old Testament views on contraception. The Old Testament does, in fact, seem to make a distinction between the life of a child and the life of a fetus (it never extracts a “fetus for a fetus” principle, for example). But as Waltke notes, the Old Testament nonetheless “protects the fetus,” And “while the Old Testament does not equate the fetus with a living person, it places great value upon it.” He also concludes regarding contraception (quoting another CT author) that “The burden of proof rests, then, on the couple who wish to restrict the size of their family.”
In the article following in the CT issue Dudley notes, Fuller Seminary Theologian Paul Jewett looked at the theological, historical, psychiatric, and sociological dimensions of the abortion issue. He concludes that “there are difficulties … moral theology faces in justifying abortion.” And “It seems the Christian answer to the control of human reproduction must be found principally in the prevention of contraception, rather than the prevention of birth.”
So, it seems that Dudley’s claim that the original evangelical position was a “pro-choice” one is overstated.
(I’m just pointing this out so people don’t assume that evangelicals pre-Roe v. Wade were raging pro-abortionists because they were not. However, there were evangelical leaders who thought it should be legal under certain circumstances.)
