The Vatican's Congregation for the Doctrine of the Faith, charged with enforcing Roman Catholic teachings, on Monday denounced the book Just Love: A Framework for Christian Sexual Ethics, by Sister Margaret A. Farley, saying that it was "not consistent with authentic Catholic theology," and should not be used by Catholics, The New York Times reported. Sister Farley is a professor emerita of Christian ethics at the Yale University Divinity School. The book presents theological rationales for, among other things, same-sex relationships, masturbation and remarriage after divorce. In a statement, Sister Farley said: "I can only clarify that the book was not intended to be an expression of current official Catholic teaching, nor was it aimed specifically against this teaching. It is of a different genre altogether."
