The document, Caring for Our Common Home: A Responsible and Fraternal Response to the Triune God, runs to more than 29,000 words and was developed by a subcommission that worked between 2022 and 2025. Its central argument is clear: the ecological crisis is ultimately inseparable from the crisis of the human person.
(ZENIT News / Rome, 09.02.2026).- The Catholic Church’s ecological teaching has taken a significant step forward with a new document that argues environmental destruction cannot be understood merely as a scientific, political or economic problem. It is also a matter of sin.
In a text published on September 2, the International Theological Commission calls for what it describes as an authentic ecological conversion and proposes a more precise expression for the moral reality involved: a “sin against creation and against the Creator.”

The formulation deliberately goes beyond the more familiar expression “ecological sin.” For the commission, the problem is not simply that human beings damage forests, water, air or biodiversity. Environmental abuse also represents a failure to recognize the divine meaning of creation and humanity’s responsibility within it.
The document, Caring for Our Common Home: A Responsible and Fraternal Response to the Triune God, runs to more than 29,000 words and was developed by a subcommission that worked between 2022 and 2025. It was approved by a majority of the commission’s members in July and authorized for publication by Cardinal Víctor Manuel Fernández, prefect of the Dicastery for the Doctrine of the Faith, after being presented to Pope Leo XIV.
Its central argument is clear: the ecological crisis is ultimately inseparable from the crisis of the human person.
The commission traces the present situation to what it calls a “triple transformation” in humanity’s relationship with nature. Over the centuries, the perception of the natural world as God’s creation weakened; an increasingly exploitative form of anthropocentrism emerged; and environmental degradation eventually developed into a crisis of planetary dimensions.
But the document refuses to respond by replacing one extreme with another.
It rejects what it calls “predatory anthropocentrism,” the idea that human beings are absolute masters entitled to exploit everything around them. At the same time, it rejects radical biocentrism and forms of deep ecology that effectively dissolve humanity’s distinctive place within creation.
