Pope Leo: Care for peace is care for life
Pope Leo XIV prayed for peace during the Regina Caeli, stressing its importance for all hearts. He referenced Laudato Si’ Week (May 17‑24) and urged members of the Laudato Si’ Movement to renew their commitment to integral ecology. The Pope celebrated the 800th anniversary of St. Francis of Assisi’s death, highlighting Francis’s message of peace with God, humanity, and all creatures. He warned that wars have slowed progress in caring for creation and linked care for peace directly to care for life.

Pope Leo XIV opened the 2026 Laudato Si’ Week by linking the Church’s call for peace directly to the protection of all life, urging believers to renew their commitment to an “integral ecology” amid the setbacks caused by ongoing wars 1 2.
The Pope celebrated the start of Laudato Si’ Week (May 17‑24) after praying the midday Regina Caeli in St. Peter’s Square.
He highlighted the week’s purpose: moving from hope to concrete action on caring for creation, as originally inspired by Pope Francis’ encyclical Laudato si’ 1 2.
Leo XIV emphasized that “care for peace is care for life,” recalling St. Francis of Assisi’s message of peace with God, humanity, and every creature.
He warned that recent wars have severely slowed progress toward ecological harmony and urged members of the Laudato Si’ Movement and all working for integral ecology to deepen their dedication 1 2.
The Pope referred to the concept of “integral ecology,” defined by Oxford’s Campion Hall as the interconnectedness of humans and the natural world, affecting political, economic, cultural, social, and theological spheres.
He noted that this vision traces back to earlier papal teachings, beginning with Leo XIII, and is central to the Church’s environmental mission 2.
2026 marks the 800‑year anniversary of St. Francis of Assisi’s death, celebrated as a Jubilee year.
Leo XIV used the occasion to invoke the saint’s love for creatures and his peace‑centered spirituality as a model for today’s ecological challenges 1 2.
By coupling peace with ecological stewardship, the Pope calls for a renewed, collective effort that integrates prayer, advocacy, and practical action.
He invites Catholics and all people of goodwill to view environmental care as inseparable from the pursuit of global peace 1 2.*
"How does Catholic teaching link ecological stewardship to peace?"
Catholic teaching links ecological stewardship to peace because caring for creation is not an optional “green” concern; it is tied to human dignity, social justice, solidarity, and ultimately peace with God. When the environment is damaged—especially by the powerful and wealthy—conflict and social instability follow; when creation is respected, human coexistence becomes more ordered and more just.
Catholic teaching rejects a merely negative definition of peace. Peace is not simply the absence of warfare or a temporary balance of power. Instead, peace is “fashioned” through efforts toward “the ordered universe willed by God, with a more perfect justice among men,” and peace that is not grounded in “integral development” will “spawn new conflicts” and forms of violence.
This matters for ecology because “integral development” includes the moral and relational dimension of how humans live with one another and with the rest of creation. So stewardship is part of building the “ordered universe” and the justice that peace requires—not an unrelated side issue.
A central Catholic linkage is explicitly stated as an “ecology of peace.” The teaching describes an inseparable relationship between:
In other words, stewardship is peacebuilding because it respects the Creator’s gift and thereby fosters right relationships inside the human community. When these relationships are broken—by environmental degradation—coexistence becomes strained.
Catholic teaching frames the ecological question not only as “physical ecology” (habitat protection) but as human ecology: protecting the “radical good of life in all its manifestations,” including the moral and social consequences of environmental harm.
John Paul II explains that environmental destruction often reflects deeper moral failures—“lack of respect for life,” where economic interests and patterns of production prevail over the dignity of workers and over the good of individuals and whole peoples. In such cases, pollution becomes not only a technical problem but an indicator of a distorted human vision that can even express “contempt for man.”
So stewardship is linked to peace because it addresses the root moral drivers of conflict: disregard for persons, injustice in economic and political structures, and the failure to protect life and dignity.
Benedict XVI’s associated peace teaching (through the “human ecology” lens) also emphasizes that respect for the environment is connected to respect for people—arguing that relationships in society and between people and the environment must be marked by “charity in truth,” and that safeguarding human dignity and family life is part of safeguarding “human ecology.”
Catholic social teaching stresses that ecological breakdown frequently impacts the poor first and hardest. A statement on political responsibility notes that care for creation is a duty of faith and a sign of concern for all people—especially the poor, who suffer “the gravest effects” of environmental attacks. It describes how environmental degradation can force the poor to leave their homes with “great uncertainty” for their future and their children’s future.
The Peace teaching on the “ecology of peace” likewise states that disregard for the environment harms human coexistence, and vice versa.
And modern papal teaching at the level of global climate policy makes the same point in a peacebuilding register: lack of respect for creation, plundering of natural resources, and the decline in quality of life due to climate change also threaten peace, and these global challenges require cooperation centered on the dignity of every human person and the common good.
So Catholic teaching links ecology to peace because environmental injustice becomes migration, poverty, and insecurity—conditions that are fertile ground for social breakdown and violence.
Catholic teaching does not treat stewardship as a private hobby; it is a public moral obligation tied to solidarity and the common good. The bishops’ statement highlights that responding to ecological challenges requires:
This connects to peace because solidarity is a moral virtue that orders institutions and helps peoples move “towards an ever more committed unity.” When institutions fail to protect creation (and the vulnerable within it), solidarity weakens and peace becomes harder to sustain.
Catholic reasoning also links environmental respect to peace through the dynamics of resources and conflict. The discussion of Benedict XVI’s contribution notes that resource misuse and conflict are mutually reinforcing: it cites the idea that natural resources can be “squandered by wars,” and that peace among peoples would provide greater protection for nature, while “the hoarding of resources, especially water,” can generate serious conflicts.
Likewise, Catholic ecumenical guidance underscores an intrinsic connection between development, human need, and stewardship of creation, explaining that development responding to human needs cannot misuse natural resources without serious consequences—and it encourages joint action aiming at “a more just society, for peace,” and for a more equitable distribution of resources.
Thus stewardship is peace-linked not only as a moral attitude but also as a demand for just structures, equitable resource use, and multilateral cooperation that reduces conflict drivers.
Putting these elements together, Catholic teaching links ecological stewardship to peace through a chain of relationships:
Catholic ecological stewardship is thus a form of peacebuilding because it protects life, restores right relationships, and supports the common good that lasting peace requires.
