This paper is based on the author's answer to a question from Theresa Notare, director of the Natural Family Planning Program of the U.S. Conference of Catholic Bishops, about what Catholic scientists and physicians can do to promote NFP and what the Catholic Church in the United States can do to help physicians and health professionals promote NFP. The paper reviews the Church's historical call for health professionals to study and to teach NFP methods, briefly analyzes the current state of NFP in Catholic health care, and provides an answer to Dr. Notare from the perspectives of research, education, and practice.
