"In the early 1920s, Margaret Sanger and her American Birth Control League (which later became Planned Parenthood) challenged this taboo and quickly won widespread acceptance among middle-class Protestants for the use of contraceptive devices. The Anglican Communion reversed course in 1930 and declared that Christian married couples had a right to use artificial birth control, and other Protestant church bodies quickly followed suit. The Federal Council of Churches' on Marriage and the Home issued a report endorsing contraception in in 1931. By the late 1930, national committees of the American Episcopal, United Methodist, United Presbyterian, and Congregational Christian Churches had officially endorsed birth control. Several Jewish organizations, including the Central Conference of American Rabbis and the National Council of Jewish Women, did the same. Though many Protestant fundamentalists continued to oppose contraception for several decades, liberal Protestants and Jews embraces it as a progressive humanitarian measure. By 1946, 3,200 ministers were members of Planned Parenthood's Clergyman's Council."
