God created marriage and sexuality for our good. In Christian marriage, a husband and wife promise to give themselves freely and completely to each other, without reservation, and to remain faithful and open to life. NFP allows the married couple to uphold all these marriage vows. The Catholic Church teaches that all acts of sexual intercourse, in order to reach their most authentic God-given meaning, must be both unitive (bringing the couple closer to each other and God) and procreative (open to the possibility of a new life being conceived). NFP does not obstruct the unitive or procreative aspects of sex. Therefore, it allows couples to plan their families in accordance with God’s design for marriage and sexuality.
