"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.'"
