In fact, within the lifetimes of many of today’s evangelical Christian believers, their churches either supported abortion rights or were neutral on it. In the 1960s and 1970s, Southern Baptists and other historically conservative Protestant denominations held that abortion was not only permissible, but also should be left to individual choice. In 1968, a group of evangelical leaders from a variety of denominations wrote in a document titled
“A Protestant Affirmation on the Control of Human Reproduction” that they could not agree whether or not abortion is sinful outright, but they could agree “about the necessity of it and permissibility for it under certain circumstances.” They even argued that “the preservation of fetal life ...
may have to be abandoned to maintain full and secure family life.”
A few years later in 1971, the Southern Baptist Convention
issued a joint resolution calling for 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.”
This resolution was in accord with Baptist views on abortion at the time.
As the Baptist Press, a news service affiliated with the Southern Baptist Convention, wrote in 2015:
“Between 1965-68, abortion was referenced at least 85 times in popular magazines and scholarly journals, but no Baptist state paper mentioned abortion and no Baptist body took action related to the subject. ... In 1970, a poll conducted by the Baptist Sunday School Board found that 70 percent of Southern Baptist pastors supported abortion to protect the mental or physical health of the mother, 64 percent supported abortion in cases of fetal deformity and 71 percent in cases of rape. Three years later, a poll conducted by the Baptist Standard news journal found that 90 percent of Texas Baptists believed their state’s abortion laws were too restrictive.”
The famed evangelical theologian Norman Geisler put it in the clearest terms in the 1971 and 1975 versions of his work
Christian Ethics: “The embryo is not fully human — it is an undeveloped person.”
It’s not Protestants, but Catholics in the United States who, as a religious community, have opposed abortion forcefully going back to the 19th century, and it is in Catholicism that we find the view that life begins at conception. Starting with
an 1869 document called Apostolicae Sedis, Pope Pius IX declared the penalty of excommunication for abortions at any stage of pregnancy.
