The Vatican's International Theological Commission has published a significant document titled “Caring for Our Common Home: A Responsible and Fraternal Response to the Triune God,” which calls for ecological conversion and defines a new term: “sin against creation and the Creator.”

This document, approved in July and released on September 2, builds on Pope Francis's earlier encyclical “Laudato Si’,” and aims to clarify the moral implications of humanity's relationship with nature. The commission states, “We propose understanding this sin against our Common Home as a ‘sin against creation and against the Creator,’ insofar as it violates the meaning of creation intended by God the Creator.”

The text emphasizes that neglecting our responsibilities towards the environment not only disrespects God’s plan but also harms our neighbors, particularly the most vulnerable and future generations. It highlights the need for a “threefold transformation” in our cultural relationship with nature, addressing the ecological crisis that has emerged since the 16th century.

Msgr. Piero Coda, secretary general of the commission, noted the importance of understanding ecological sin in a manner akin to social sin, stating, “This underscores the profound seriousness of the ‘ecological turning point’ that challenges our conscience today.” The document also proposes practical guidelines for “ecological conversion,” emphasizing mindful consumption and respect for life.

It concludes with a call for interreligious cooperation in caring for creation, affirming that the spiritual and religious dimensions are crucial for effective ecological action.
