A outcry went through the Vatican, a review committee was established, and the Congregation for the Doctrine of the Faith warned of a "great danger for the faithful." But what had happened? A woman had published a book in which she developed a new, modern Christian sexual morality. She claims that there are theological justifications for homosexual relationships, masturbation, and remarriage. Topics that, according to the Vatican, are incompatible with Catholic theology. Even more frustrating for the Church is that the author is not only a professor at Yale University but also a nun. Sister Margaret A. Farley sparked global controversy with her book 'Just Love: A Framework for Christian Sexual Ethics.' In it, she addresses the key questions in the areas of embodiment, gender, and sexuality, and then elaborates on her concept of a just sexual ethics.
