VATICAN CITY CNS — Pope Leo XIV began the five-week Season of Creation by calling on the faithful to step away from the frenzy of daily life to “hear the melodious voice of creation,” stressing that “it is not yet too late” to repair humanity’s relationship with the environment.
Celebrating Mass on the World Day of Prayer for the Care of Creation in the gardens of the papal villa and the Borgo Laudato Si’ ecology project in Castel Gandolfo, Sept. 1, the Pope said contemplating creation and its Creator should lead people to recognize their responsibility for protecting it.
“Thus, as we become conscious of our shortcomings and failures, we can renew our commitment to restoring the relationships among all creatures according to the will of their Creator,” he said.
The theme chosen for the 2026 World Day of Prayer for the Care of Creation echoes the biblical call to “beat swords into plowshares” and connects armed conflict with environmental destruction.
In a June 2 statement, the Dicastery for Promoting Integral Human Development said that “the now widespread awareness of the impact of war on natural resources has not led to the creation of adequate institutions or to responsible decisions aimed at preventing conflicts and resolving disputes peacefully.”
In his homily during the Mass, Pope Leo said the call to transform weapons into instruments that sustain life remains urgent.
“What has been used for destruction can be redirected toward life, toward the care of the poor, the nourishment of the hungry, and the safeguarding of creation,” he said, quoting his message for the day.
Militaries account for about 5.5% of global greenhouse gas emissions and contribute to water pollution, soil contamination and waste generation, according to a joint study by the UK-based Scientists for Global Responsibility and the Conflict and Environment Observatory. The World Wide Fund for Nature estimated that the first three years of the Russia-Ukraine war alone generated the equivalent of about 230 million metric tons of carbon dioxide — a greenhouse gas that traps heat from sunlight, warming the planet.
Pope Leo also focused on access to clean water in his September prayer intention, released Sept. 1 by the Pope’s Worldwide Prayer Network.
Thanking God for the gift of water, the Pope prayed for the “right of every brother and sister to drink without fear and without inequality.”
“Forgive us for turning it into a commodity, forgetting that it is a universal gift, a right without borders, meant for all your children,” he prayed. “We see with pain so many brothers and sisters who lack clean water, who walk for miles to find it, who become ill due to its scarcity.”
During the Mass, Pope Leo said passages from the Book of Wisdom and Psalm 18 encourage Christians to recognize God through the “beauty and power of creation.”
“All creation speaks to us of the greatness of its Creator, if only our eyes and hearts remain open to such a great mystery,” he said.
By looking with wonder at the birds of the air and the flowers of the field, the Pope said, Christians can better understand the greatness of God’s love for humanity.
“If the Lord does not fail to bestow such splendid beauty upon plants and animals and provide for all their needs, how much more attentive will he be to the needs of his beloved sons and daughters,” he said.
The Season of Creation runs from Sept. 1 through Oct. 4, the feast of St. Francis of Assisi. The Catholic Church’s observance of the World Day of Prayer for the Care of Creation was established by Pope Francis in response to an initiative of Orthodox Ecumenical Patriarch Bartholomew of Constantinople. The Orthodox Church has observed Sept. 1 as a day of prayer for creation since 1989.
The 2026 season will conclude as the Church marks the 800th anniversary of the death of St. Francis of Assisi, who is the patron saint of ecology.
Pope Leo closed his homily by reciting portions of St. Francis’ Canticle of the Creatures:
“Praised be you, my Lord, with all your creatures, especially Sir Brother Sun… Praised be you, my Lord, through Sister Moon and the stars… Praised be you, my Lord, through Brother Wind… Praised be you, my Lord, through Sister Water… Praised be you, my Lord, through Brother Fire… Praised be you, my Lord, through our Sister Mother Earth, who sustains and governs us.”
