Can Anything Change in Catholic Moral Teaching?

Abstract

This article examines whether change is possible within Catholic moral teaching, with particular attention to the relationship between doctrinal continuity and development. Drawing on the concept of aggiornamento articulated by Pope John XXIII, it situates moral teaching within evolving historical and cultural contexts. It argues that while the objective content of the faith, grounded in the deposit of revelation, remains unchanged, the Church’s understanding and pastoral application of moral principles develop over time. Through an analysis of key moral issues—contraception, organ transplantation, homosexuality, and capital punishment—the article identifies a pattern of organic growth marked by both continuity and discontinuity. It concludes that such developments represent not a rupture in doctrine, but a deepening of the Church’s engagement with enduring moral truths.
