The Vatican’s International Theological Commission has called for a deeper Christian response to environmental destruction, proposing that serious harm to nature be understood as a “sin against creation and against the Creator.”
The position was presented in a more than 30,000-word document published on September 2 after three years of work by the commission and review by Pope Leo XIV.
The document, titled “Caring for Our Common Home: A Responsible and Fraternal Response to the Triune God,” argues that protecting the planet for future generations is both an ethical and theological responsibility.
The commission said the scale of the environmental crisis requires urgent action from governments, public officials and individuals to preserve the planet and ensure that humanity can continue to inhabit it sustainably.
Central to the document is the proposal to develop an “ecological spirituality” rooted in the Christian understanding of the Triune God and the belief that creation is fundamentally interconnected.
The commission also revisited the concept of “ecological sin,” first introduced during the 2019 Synod of Bishops on the Amazon.
It proposed understanding ecological sin as actions or failures to act that harm God, neighbours, communities and the environment.
However, the commission argued that simply describing ecological sin in terms of environmental damage does not fully capture the religious dimension of the issue.
It said environmental wrongdoing should also be understood as a rejection of what Christians believe to be God’s purpose for creation.
The commission therefore proposed describing it as a “sin against creation and against the Creator,” arguing that environmental destruction has consequences that extend beyond physical damage to the natural world.
The document also drew parallels between ecological wrongdoing and the Catholic concepts of social sin and structures of sin, under which harmful individual behaviours can accumulate and develop into wider systems that influence society.
The commission called for ecological principles to become part of everyday spirituality, influencing how people work, rest, consume resources, relate to nature and interact with other people.
It warned that modern economic systems and what it described as the dominant technocratic paradigm can encourage excessive consumption and contribute to environmental deterioration.
The document urged Christians to examine their personal and family consumption patterns and reduce unnecessary energy use in homes and transportation.
It also encouraged environmentally responsible diets and more deliberate purchasing decisions, stressing that consumption choices have moral implications.
The commission further called for voluntary restraint in the exploitation of natural resources, particularly in wealthy countries whose consumption levels place greater pressure on the planet.
On climate responsibility, it argued that those responsible for the greatest environmental damage should face the strongest expectations to adopt more ambitious ecological policies.
However, it cautioned against wealthy nations placing disproportionate demands on poorer countries, particularly when richer societies remain unwilling to change their own consumption patterns.
The document also expanded the Catholic principle of the universal destination of goods, arguing that the Earth’s resources and ecological systems must be protected not only for people living today but also for future generations and the wider flourishing of life.
The commission concluded by calling for an “ecological turning point” involving a profound change in how humanity understands its relationship with creation.
It said religions have an important role to play in promoting conservation, altruism and respect for the natural environment and in encouraging behavioural changes that support the common good.
Despite the significance of the document, the commission stressed that its publications are advisory and do not constitute official church magisterium.
The body is instead tasked with helping the Catholic Church, particularly its doctrine office, study and develop church teaching.
