On Wednesday afternoon, marking the tenth anniversary of Pope Francis’ encyclical, Laudato Si’, Pope Leo XIV addressed participants in the
Raising Hope Conference, organised by the Laudato Si’ Movement.
In his address, the Pope expressed gratitude for the legacy of Pope Francis’ encyclical, noting how its message has inspired schools, dioceses, academic programmes, and international dialogue.
“Its impact,” he said, “has extended to summits, interreligious initiatives, economic and business circles, as well as theological and bioethical studies.” Above all, he noted that the phrase “care for our common home” has become a standard phrase, used in academic work and public discourse across peoples and continents.
A conversion of heart
While recalling the achievements of the past decade, Pope Leo emphasised that the challenges identified in Laudato Si’ are “even more relevant today than they were ten years ago.” These challenges, he said, are not only political and social, but also spiritual, calling for what Pope Francis described as a “conversion of heart.”
The Pope explained that the heart “is where the deepest searching takes place, where one’s ultimate identity is found, and where decisions are forged. It is only by returning to the heart that a true ecological conversion can take place.” This transformation, he continued, means shifting “from collecting data to caring; from environmental discourse to lifestyles inspired by faith and love of God.”
All are one
Quoting Pope Francis’ description of Saint Francis of Assisi, the Holy Father reminded participants that ecological concern, justice for the poor, social commitment, and inner peace are inseparable.
Looking ahead to upcoming global summits, including COP30 and the UN’s 2026 Water Conference, the Pope urged leaders to heed the cries of “the Earth and the poor, families, indigenous peoples, involuntary migrants and believers throughout the world.”
What will be our answer?
Concluding his address, Pope Leo asked the question: “God will ask us if we have cultivated and cared for the world that He created, and if we have taken care of our brothers and sisters. What will be our answer?”

In this Jubilee year of Hope, it is fitting that the season’s theme is Peace with Creation, the hope of all who work to bring God’s dream of justice and peace to reality. The symbol is the Garden of Peace, inspired by Isaiah 32:14-18 where the prophet portrays a desolate creation, devoid of peace due to injustice and the broken relationship between God and humankind. Isaiah’s hope and ours is that Creation will find peace when justice is restored.
En este año jubilar de la esperanza, es apropiado que el tema de la temporada sea «Paz con la Creación», la esperanza de todos los que trabajan para hacer realidad el sueño de Dios de justicia y paz. El símbolo es el Jardín de la Paz, inspirado en Isaías 32:14-18, donde el profeta describe una creación desolada, desprovista de paz debido a la injusticia y a la ruptura de la relación entre Dios y la humanidad. La esperanza de Isaías y la nuestra es que la Creación encuentre la paz cuando se restaure la justicia.
