"Environmental Destruction as Sin Against God"... Catholic Church Begins Serious Discussion on Confession

Proposal to Define Environmental Destruction as “Sin Against the Creator”
Expanding Environmental Issues into Areas of Faith and Morality
The Vatican Also Emphasizes Preservation of Creation and Ecological Conversion

The Catholic Church is drawing attention as it moves in earnest to address acts of environmental destruction as a concept of “sin.”

On September 4 (local time), EU-specialized media Euractiv cited Vatican News to report that the International Theological Commission (ITC) released a document titled "Caring for Our Common Home" on September 2 with the approval of Pope Leo XIV. Developed through discussions from 2022 to 2025, the document addresses the ecological crisis—including climate change, loss of biodiversity, and air and water pollution—from a theological perspective.

Of particular note is the concept proposed by the International Theological Commission of “sin against Creation and against the Creator.” The Commission argues that indiscriminate exploitation and destruction of nature by humans is not only an environmental harm, but also an act that violates the order established by God and the responsibility entrusted to humanity.

In Catholicism, the "seven deadly sins"—pride, greed, envy, wrath, lust, gluttony, and sloth—are regarded as the roots of all evil. The Commission’s document draws attention for suggesting that environmental destruction should be recognized as an evil comparable to these sins. Consequently, the Commission urges “ecological conversion,” calling for changes in production and consumption, as well as transportation and energy use.

This discussion could potentially extend to the Catholic sacrament of confession. If recognizing acts of environmental harm as moral wrongdoing and the need for repentance becomes widespread, reflection and confession of ecological sins might become established as an area within the practice of confession.

However, at present, the Catholic Church has not officially designated environmental destruction as a “mortal sin.” Analysts note that the newly released document does not define all acts of environmental harm as mortal sins or mandate confession for them, but rather serves as a proposal to redefine responsibilities toward the environment from theological and moral standpoints.

Pope Francis, too, has emphasized the need for repentance regarding environmental destruction and called for “ecological conversion.” On September 1, Pope Leo XIV also stressed during a Mass for the preservation of creation that humanity must recognize its wrongdoing and restore the relationship between Creator and creation.
