Out of family life education grew comprehensive sexuality education, which taught sexuality as a public health topic and included information on contraceptives and, eventually, sexual diversity. Interactions between the National Council of Churches and Mary Steichen Calderone, a Quaker and public health professional, led to the founding of SIECUS in 1964 as the leader of comprehensive sexuality education. Chapter 4 argues that the “new morality,” a liberal theological trend also known as situation ethics, shaped comprehensive sexuality education and incited the intense conservative Christian opposition known as the “sex education controversies.” The new morality, with its rejection of absolutist interpretations of right and wrong behavior, tipped sex education further toward progressive sexual values. Responding to the new morality of comprehensive sexuality education, conservative Christians protested that children would learn an “anything goes” curriculum that violated their beliefs in modesty and the exclusive place of sexuality within a monogamous, heterosexual marriage.
