The way Catholics care for the natural world is inseparable from their relationship with God, according to a new document from the International Theological Commission that calls Christians to view care for creation through the lens of faith, responsibility and moral conversion.
The document, “Caring for Our Common Home – A Responsible and Fraternal Response to the Triune God,” was published Sept. 2 with the authorization of Pope Leo XIV, according to Vatican News. The text grew out of theological reflections conducted between 2022 and 2025 and addresses what it describes as an increasingly serious ecological and social crisis.
Rather than treating environmental concerns primarily as political or scientific questions, the commission places them within Catholic theology. Creation bears the imprint of the Triune God, the document explains, and the human person is called to live in right relationship with God, neighbor and the created world.
“Nothing and no one is a monad,” the document states. “Everything is interrelated” within “a single community of life,” according to Vatican News. The commission says this understanding calls Christians to practice gratitude toward God, mercy and solidarity toward others, and responsible care for the common home.
The document also distinguishes between what science and faith can tell humanity about the universe. While scientific cosmology can legitimately investigate how the universe developed, Christian faith addresses the deeper question of why anything exists at all. God, the commission teaches, freely calls creation into existence and gives it an origin that is metaphysical as well as physical.
The commission points to the biblical Sabbath as another important principle for understanding humanity’s place within creation. According to Vatican News, the document says the Sabbath allows the Earth to rest while giving humanity an opportunity to thank God through prayer. It can also teach people to “adopt a disinterested gaze, freed from the appetite to possess, dominate or attack.”
At the same time, the document warns of serious environmental deterioration, citing declining biodiversity, air pollution, worsening water quality and the environmental destruction caused by war. These problems frequently fall most heavily upon the poor, including communities whose resources are exploited or who are forced to migrate.
The commission therefore calls for more than technological solutions. Changes to production, consumption, transportation and energy systems may be necessary, but the document also calls for “a change in cultural values” and an authentic ecological conversion in the way people live.
Significantly for Catholics, the commission proposes describing serious environmental wrongdoing as “sin against Creation and against the Creator.” According to Vatican News, this language connects damage to creation with a rejection of God’s plan and emphasizes the personal moral responsibility involved in caring for the world God has entrusted to humanity.
The document also rejects two competing approaches to humanity’s relationship with nature. One is a predatory anthropocentrism that treats human beings as the “absolute master of all creation.” The other is an approach that effectively absolutizes nature itself.
Instead, the commission embraces what it calls “situated anthropocentrism,” presenting human beings as “stewards and servants of Creation.” Humanity possesses a unique responsibility within creation, but that authority is to be exercised according to the will of God, the true owner of creation, through responsible stewardship and service.
The Eucharist occupies a particularly important place in this Catholic vision. The document describes the Eucharist as an “ecological school” capable of fostering “a positive and proactive attitude towards nature,” rather than one driven simply by utility or fear.
Practical Christian responses outlined by the commission include moderation in consumption, fasting, reverence for creation, solidarity with the poor and recognition that wealthy nations may bear different responsibilities than poorer countries. The document also stresses that environmental concerns cannot be separated from respect for human life.
According to Vatican News, the commission describes the sacredness of human life as an “unconditional and inalienable right” that governments must protect and promote. It also connects care for creation with rejection of war, fraternity, mercy, concern for future generations and the preferential option for the poor.
The commission additionally says Christians can cooperate with members of other religions where they share a commitment to responsibly caring for creation. “From the standpoint of the Christian faith, the doors are open to interreligious cooperation in the common task of respectfully caring for all Creation,” the document states.
Ultimately, however, the document returns environmental stewardship to a distinctly theological foundation. How humanity treats creation reveals something about how humanity understands and responds to the Creator.
The commission calls for an “ecological turning point” that is both cultural and spiritual, pointing to St. Francis of Assisi as an example. Despite the seriousness of environmental problems, the document ends with Christian hope rather than despair, affirming confidence in the God who makes “all things new.”
