The teachings of NFP International are listed below.
Ecological breastfeeding truly does space babies without periodic abstinence. Repeated research shows that mothers who follow the Seven Standards of eco-breastfeeding experience extended breastfeeding infertility. St. John Paul II encouraged mothers to breastfeed for at least two years and beyond.
The New Evangelization helps couples to understand how Jesus is the author of the teachings of the Church including its difficult moral teachings.
Teaching Catholic morality means letting couples know that it is morally wrong to engage in masturbation and marital sodomy at any time including the fertile time. Due to our culture, this is a necessary part of teaching marital chastity.
The Covenant theology is a straightforward statement about the meaning of sexual union. “Sexual intercourse is intended by God to be, at least implicitly, a renewal of the marriage covenant.” A common reaction is “That makes sense.“ In fact, it makes such good sense that it has helped non-Catholics to accept Catholic teaching on birth control and eventually enter the Church.
All signs of fertility and infertility are taught in a highly effective cross-checking way.
