Sister Margaret A. Farley published a book back in 2006 entitled Just Love: A Framework for Christian Sexual Ethics.
The Congregation for the Doctrine of Faith at the Vatican has studied this book thoroughly and decided to express "profound regret" to Sister Farley with a Notification.
"Among the many errors and ambiguities of this book are its positions on masturbation, homosexual acts, homosexual unions, the indissolubility of marriage and the problem of divorce and remarriage".
"Sr. Farley writes: 'Masturbation… usually does not raise any moral questions at all'. ... This statement does not conform to Catholic teaching: “Both the Magisterium of the Church, in the course of a constant tradition, and the moral sense of the faithful have been in no doubt and have firmly maintained that masturbation is an intrinsically and gravely disordered action. ... For here sexual pleasure is sought outside of the sexual relationship which is demanded by the moral order and in which the total meaning of mutual self-giving and human procreation in the context of true love is achieved".
"Sr. Farley writes: 'My own view ... is that same-sex relationships and activities can be justified according to the same sexual ethic as heterosexual relationships and activities'. ... This opinion is not acceptable. The Catholic Church, in fact, distinguishes between persons with homosexual tendencies and homosexual acts. Concerning persons with homosexual tendencies, the Catechism of the Catholic Church teaches that “they must be accepted with respect, compassion and sensitivity. Every sign of unjust discrimination in their regard should be avoided” . Concerning homosexual acts, however, the Catechism affirms: “Basing itself on Sacred Scripture, which presents homosexual acts as acts of grave depravity, tradition has always declared that homosexual acts are intrinsically disordered. They are contrary to the natural law. They close the sexual act to the gift of life. They do not proceed from a genuine affective and sexual complementarity. Under no circumstances can they be approved”".
Check out Sister Farley's response:
I appreciate the efforts made by the Congregation and its consultants, over several years, to evaluate positions articulated in that book, and I do not dispute the judgment that some of the positions contained within it are not in accord with current official Catholic teaching. In the end, 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.
Regardless, the Vatican is not happy with the non-doctrinal information contained in this non-doctrinal book.
"With this Notification, the Congregation for the Doctrine of the Faith expresses profound regret that a member of an institute of consecrated life, Sr. Margaret A. Farley R.S.M., affirms positions that are in direct contradiction with Catholic teaching in the field of sexual morality.
Sadly, the Roman Catholic Church can authoritatively speak of profound regret when it comes to acts of grave depravity, intrinsically and gravely disordered action, and acting contrary to natural law.
