Natural Family Planning International is different from every other NFP organization because of our completeness. That’s why we title our NFP manual as Natural Family Planning: The Complete Approach.
Chapter 1 is an evangelical effort that places the teaching of Humanae Vitae in the context of faith in the Church based on the Last Supper promises of the Lord Jesus. It offers theological support for Humanae Vitae through the covenant theology of the marriage act. For more on that, see my Sex and the Marriage Covenant: A Basis for Morality (Ignatius, 2005). This is the theology that helped to persuade Kimberly and Scott Hahn to accept Catholic teaching on birth control when they were still Protestants, and that was their first step toward full communion with the Church. See their Rome Sweet Home.
Chapter 6 deals with Ecological Breastfeeding. This is the most natural of all the forms of birth spacing. And it DOES work when properly understood and practiced. For more on that, see The Seven Standards of Ecological Breastfeeding (Lulu 2008).
The how-to chapters are based on the crosschecking system refined by Dr. Konald A. Prem, then a professor of OB and Gyn at the University of Minnesota Medical School.
Except for the witness statements in Chapter 7, the text is in Q and A format, thus making it easy to read and understand. It also has a comprehensive index.
The NFPI website has a trove of information for anyone interested in the various aspects of natural family planning.
