A summary of Vatican News’ overview of Pope Leo’s first encyclical.
Pope Leo XIV’s first encyclical, Magnifica humanitas (The Magnificent Humanity), examines the Church’s social doctrine in the age of artificial intelligence. Signed on the 135th anniversary of Leo XIII’s Rerum novarum, the document defends human dignity, the value of work, social justice, and peace at a time when digital power is reshaping society ever more profoundly.
The encyclical opens with the words: “The magnificent humanity created by God stands today before a decisive choice.” Its subtitle is: “On care for the human person in the age of artificial intelligence.”
Published on Monday, 25 May, and signed on 15 May, the document continues the social teaching tradition inaugurated by Leo XIII in Rerum novarum. Pope Leo XIV addresses one of the defining issues of our time: artificial intelligence and its impact on society, the economy, warfare, and our understanding of the human person.
The Pope stresses that technology is not evil in itself, but neither is it neutral. It reflects the goals of those who design, finance, and employ it. For this reason, the development of artificial intelligence must be guided by shared responsibility, subsidiarity, and solidarity within communities.
In the first chapter, the Pope reviews the development of Catholic social teaching in the recent Magisterium and in the Second Vatican Council. He describes social doctrine as a “theology of communion lived within history,” helping believers interpret world events in the light of the Gospel. Recalling the teaching of his predecessors, he highlights human dignity, the common good, solidarity, care for creation, and peace.
In the second chapter, Leo XIV defends the inalienable worth of every human being at a time when people risk being reduced to instruments of production and efficiency. He reminds readers that every person is created in the image of God and that human dignity is neither acquired nor earned. The Pope also reaffirms the protection of human life from conception to natural death, defends the rights of minorities, and calls for a stronger role for women in society.
The encyclical further emphasizes the importance of the common good, subsidiarity, and social justice in the digital world. Leo XIV warns against the concentration of knowledge and technology in the hands of a few, which can deepen inequality. Social justice, he argues, includes equitable access to education and technology, as well as protecting the vulnerable from hate speech, disinformation, and economic exploitation.
The Pope also reflects on the situation of migrants, stating that the way they are treated reveals whether a society is guided by fear or by fraternity. At the same time, he calls the Church to an examination of conscience and to attentive listening to victims of abuse.
In the third chapter, the Pope turns directly to the question of artificial intelligence. He warns against the “technocratic paradigm,” in which efficiency and economic gain become the primary criteria for decision-making. Artificial intelligence may imitate human beings, but it lacks moral conscience, empathy, and a spiritual dimension. For this reason, international ethical regulation and clear legal frameworks are urgently needed.
The Pope also draws attention to the environmental impact of AI and insists that “artificial intelligence must be disarmed.” Technology must not become an instrument of military or economic rivalry. At the same time, he rejects transhumanist visions that regard human limitations as defects to be eliminated.
In the fourth chapter, Leo XIV addresses truth, education, and work. He defends responsible journalism, transparency in algorithms, and critical thinking in the digital environment. Technology should free people from burdensome labour, not replace them in the pursuit of maximum profit.
The encyclical also highlights the importance of the family and warns against new forms of digital power, including profiling, behavioural prediction, and algorithmic manipulation. The Pope speaks of new forms of slavery created by technology and recalls the exploitation associated with the extraction of rare earth minerals.
In the fifth chapter, the Pope examines questions of war and peace in the age of artificial intelligence. He criticizes the normalization of war in international politics and calls for moving beyond just-war theory through dialogue, diplomacy, and forgiveness. He regards AI-driven weapons systems, nuclear rearmament, and digital manipulation as especially grave threats.
The encyclical concludes with a call to build a “civilization of love” even amid technological transformation. Leo XIV reminds readers that the name of God must never be invoked to justify violence or war, and he calls Christians to bear witness to “the beauty of the magnificent humanity in which God has made His dwelling.”
