One of the most durable myths in recent history is that the religious right, the coalition of conservative evangelicals and fundamentalists, emerged as a political movement in response to the U.S. Supreme Court’s 1973 Roe v. Wade ruling legalizing abortion. The tale goes something like this: Evangelicals, who had been politically quiescent for decades, were so morally outraged by Roe that they resolved to organize in order to overturn it.

This myth of origins is oft repeated by the movement’s leaders. In his 2005 book, Jerry Falwell, the firebrand fundamentalist preacher, recounts his distress upon reading about the ruling in the Jan. 23, 1973, edition of the Lynchburg News: “I sat there staring at the Roe v. Wade story,” Falwell writes, “growing more and more fearful of the consequences of the Supreme Court’s act and wondering why so few voices had been raised against it.” Evangelicals, he decided, needed to organize.

Some of these anti- Roe crusaders even went so far as to call themselves “new abolitionists,” invoking their antebellum predecessors who had fought to eradicate slavery.

But the abortion myth quickly collapses under historical scrutiny. In fact, it wasn’t until 1979—a full six years after Roe—that evangelical leaders, at the behest of conservative activist Paul Weyrich, seized on abortion not for moral reasons, but as a rallying-cry to deny President Jimmy Carter a second term. Why? Because the anti-abortion crusade was more palatable than the religious right’s real motive: protecting segregated schools. So much for the new abolitionism.

Today, evangelicals make up the backbone of the pro-life movement, but it hasn’t always been so. Both before and for several years after Roe, evangelicals were overwhelmingly indifferent to the subject, which they considered a “Catholic issue.” In 1968, for instance, a symposium sponsored by the Christian Medical Society and Christianity Today, the flagship magazine of evangelicalism, refused to characterize abortion as sinful, citing “individual health, family welfare, and social responsibility” as justifications for ending a pregnancy. In 1971, delegates to the Southern Baptist Convention in St. Louis, Missouri, passed a resolution encouraging “Southern Baptists to work for legislation that will allow the possibility of abortion under such conditions as rape, incest, clear evidence of severe fetal deformity, and carefully ascertained evidence of the likelihood of damage to the emotional, mental, and physical health of the mother.” The convention, hardly a redoubt of liberal values, reaffirmed that position in 1974, one year after Roe, and again in 1976.

When the Roe decision was handed down, W. A. Criswell, the Southern Baptist Convention’s former president and pastor of First Baptist Church in Dallas, Texas—also one of the most famous fundamentalists of the 20th century—was pleased: “I have always felt that it was only after a child was born and had a life separate from its mother that it became an individual person,” he said, “and it has always, therefore, seemed to me that what is best for the mother and for the future should be allowed.”
