"With the exception of some Protestant fundamentalists, Catholics stood almost alone in their refusal to countenance artificial birth control and sterilization under any circumstances. While a sizeable minority of Catholics (a minority that included 30 percent of married, white Catholic women of childbearing age, according to a 1955 survey) quietly violated official Catholic teaching by using forbidden means of birth control and then abstaining from communion until they received absolution for their "sin" from a priest, the majority of Catholics continued to follow their church's teaching on this issue, and some launched public efforts to oppose the rapid liberalization of public attitudes toward contraception and sterilization. They believed that birth control was equally wrong for both Catholics and non-Catholics, because the use of contraception not only violated nearly two thousand years of Church teaching but was also an offense against natural law which should have been accessible to anyone-whether or not they were Catholic-by reason alone. In their view, abortion, contraception, and sterilization were violations of the same natural law principles, so they were dismayed when Protestants, who for the most part still opposed abortion, nevertheless rejected natural law arguments against contraception and sterilization, thus jettisoning the philosophical principles on which, for Catholics, opposition to abortion rested. Protestants saw the matter differently of course. Though nineteenth-century Protestants had often conflated contraception and abortion, Protestants of the mid-twentieth century separated the two issues, approving of one as a beneficial social good while condemning the other as the taking of a human life that should be performed only in extreme circumstances. But Catholics were convinced that a compromise on contraception would inevitably lead to an acceptance of abortion, and they became increasingly vocal in their defense of the natural law principles that condemned both practices. Indeed, in their successful campaign against a referendum to legalize birth control in Massachusetts in 1948, they claimed that birth control was "like abortion" and against "God's law.""
