The Catholic Church notably condemns all forms of artificial birth control and advocates natural family planning as the only morally licit means of spacing births. This teaching is presented as the quintessential pathway to the fullness of human sexuality, but many Catholics struggle with it, and the magisterium itself recognizes that this path is not an easy one to follow. This article uses recent developments in Catholic moral theology around the notion of structural sin to examine the structural constraints complicating ordinary Catholics’ pursuit of their tradition’s vision for marital sexuality, demonstrating that larger structural forces can considerably affect the perceived viability of Catholic teaching on contraception. As a result, the article highlights the importance of linking Catholic sexual ethics and social ethics to provide a more credible vision for a more compassionate approach to married life.
