One valuable but perhaps less known and less used catechetical resource in the United States is the United States Catholic Catechism for Adults. This document was produced and approved by the United States Conference of Catholic Bishops and it received a recognitio from the Holy See. Since it is an authoritative but perhaps less well known document, we thought it would be worthwhile to include segments from this catechism. The following excerpt is important because it offers an official explanation of the unitive and procreative ends of marriage and the marital act. This is worth sharing because there are people online who have expressed confusion and/or taken issue with the language of the “unitive end” of marriage and the marital act since the language of the “inseparable unitive and procreative ends” became the normative language of the magisterium when speaking about marriage and the marital act. However, if we are going to think with the mind of the Church, we must be willing to speak its language in its preferred terms. This United States Catechism provides an authoritative explanation of the unitive and procreative ends.
