"Today, Catholics and evangelical Protestants assert shared religious beliefs in conflicts over sexual norms. This coalition did not exist at the time of Roe, for example, when evangelical Protestants had different views about abortion and were unwilling to join in political coalition with Catholics in opposing it. But the views of evangelical Protestants about abortion have changed in the intervening years, as has their willingness to assert claims of common faith with Catholics on the question. Theological differences, of course, persist. But since the era of Ronald Reagan’s election, when Republican leaders encouraged evangelical Protestants to enter politics in common cause with Catholics opposed to abortion, a conservative, cross-denominational coalition of Christians has pursued self-consciously traditional and conservative ends."
