Pope Leo warns of AI's risks to humanity in his first encyclical
Pope Leo XIV has just declared artificial intelligence one of the defining moral challenges of our time, in his first encyclical: a formal letter intended to guide moral, social and theological thought. Titled Magnifica Humanitas (Magnificent Humanity), it argues technology must serve humanity, rather than concentrate power or weaken human dignity. He presented it at the Vatican alongside AI developer Christopher Olah, cofounder of Anthropic, who acknowledged that companies like his need moral guidance to guard against “incentives and constraints that can sometimes conflict with doing the right thing”, the New York Times reported. “Technology is not simply a tool,” read the roughly 42,300-word open letter. “When it becomes the standard by which everything is judged, it begins to dictate what matters and what can be discarded, reducing creation to an object of exploitation and human beings to mere cogs in a system driven toward ever greater efficiency.” Christopher Olah, cofounder of Anthropic, has acknowledged companies like his need moral guidance. Maurizio Brambatti/AAP It warns that AI is never truly neutral, but “takes on the characteristics of those who devise, finance, regulate and use it”. And it calls for ethical oversight, social justice, protection of workers, responsible governance and peace. Automated warfare The encyclical criticises the use of AI in warfare, calling for imposing the “most rigorous ethical constraints” on weapons developed using AI. As governments invest heavily in autonomous military technologies and AI-assisted defence systems, the “growing ease” of deploying them makes war more likely and “less subject to human control”, it warns. This “violates the principle that armed force should be used only as a last resort in cases of legitimate self-defense”. The letter also criticises the growing concentration of technological power, and systems that reduce people to data or economic functions. It promotes what it calls a “civilisation of love”, centred on human dignity, solidarity, truth, compassion and the common good. Pope Leo’s response to the the AI revolution deliberately references his predecessor Pope Leo XIII’s response to the problems of the Industrial Revolution, Rerum Novarum (“Of New Things”), in 1891. Though Magnifica Humanitas was released on May 25 2026, it is symbolically dated May 15, the date of Rerum Novarum.

In first encyclical, Pope Leo urges world to 'disarm' AI amid increased ...
VATICAN CITY (CNS) -- Presenting the first encyclical of his pontificate, Pope Leo XIV warned that artificial intelligence must be "disarmed," urging governments, tech leaders and society to confront the rapidly growing technology before it weakens human relationships, critical thinking and peace itself.With its authoritative teaching, the 82-page encyclical, "Magnifica Humanitas" ("Magnificent Humanity"), significantly boosts the Catholic Church's position as an active voice in discussions over artificial intelligence, autonomous weapons, labor, human dignity and the concentration of technological power among a handful of corporations."Peace, not merely the absence of war, is justice at work," Pope Leo said May 25 during a presentation unveiling the document in the Vatican's Synod Hall to an audience filled with members of the Roman Curia, reporters and special guests. "But when technology weakens our critical sense, peace itself is at risk."The pope said he wrote the encyclical after hearing from scientists, engineers, political leaders, parents and teachers about the promises and dangers posed by artificial intelligence. While some were enthusiastic about the technology, he said others expressed fears over future generations and increasingly autonomous weapons systems.While he acknowledged the benefits of AI, Pope Leo was clear in saying more scrutiny needs to be applied to this developing technology."Artificial intelligence needs to be disarmed," the pope said. "The word is strong, I know, but deliberately chosen because this moment needs words capable of attracting attention, awakening consciences and indicating paths forward for humanity."Pope Leo has frequently cautioned against the unchecked development of AI since the beginning of his pontificate, warning that the technology risks weakening human discernment, distorting reality and replacing authentic relationships with simulations of human interaction.Anchoring his address on the church’s annual World Communications Day theme, the pope said artificial intelligence is increasingly simulating "human voices and faces," while raising deeper questions surrounding consciousness, responsibility, friendship and truth."We do not possess technical answers, nor do we seek to displace those with expertise," the pope said in his May 25 presentation. "But we bring a wisdom concerning the human that our present time desperately needs: every person is unique and irreplaceable."The Holy See's engagement with majo...
The Pope's AI Encyclical: What Magnifica Humanitas Actually Says About ...
Rome Entered the AI Debate Yesterday Pope Leo XIV stood at the Vatican's Synod Hall on May 25 and personally presented his first encyclical to the world. That was unusual enough. The second anomaly was who stood beside him: Christopher Olah, co-founder of Anthropic and the researcher who built the field of mechanistic interpretability. The first U.S.-born pope, a trained mathematician, chose to launch his most significant teaching document alongside one of the engineers most focused on understanding what is actually happening inside large AI systems. Magnifica Humanitas runs to 42,300 words and 235 pages, organized across five chapters and an introduction. Its publication date was not accidental. Leo XIV signed it on May 15, 2026, the 135th anniversary of Rerum Novarum, the landmark 1891 encyclical from his predecessor and namesake Pope Leo XIII. That text, issued as factories were dismantling craft labor across Europe and America, argued that workers had dignity and could not be treated as interchangeable production inputs. It became foundational to labor law in the century that followed. The signature date is a thesis statement before the text begins. The new encyclical applies the same structure to AI. Its central argument is framed in paragraph nine: "Technology is never neutral, because it takes on the characteristics of those who devise, finance, regulate and use it." From there the document builds a case that covers autonomous weapons, labor displacement, AI-synthesized media, children's cognitive development, and the concentration of AI capabilities in a small number of private firms. The position throughout is not that AI should be rejected but that the question of whose AI it is, and in whose interests it operates, is one humanity has not answered. The Anthropological Frame The encyclical's diagnostic sentence appears at paragraph four: "Never has humanity had such power over itself." The sentence is not celebratory. It describes vertigo, the awareness that the question of what to do with that power has not been resolved. The document's core argument follows from that vertigo. AI, in the encyclical's framing, forces a confrontation with questions humanity has been avoiding: what are human cognition, labor, creativity, and relationship if machines can perform them? Leo XIV's encyclical argues the challenge is "not technological, but anthropological. Safeguarding faces and voices ultimately means safeguarding ourselves." This is a specific t...
Pope Leo Uses First Major Papal Text to Warn About Dangers of AI - TIME
Pope Leo XIV has issued the first major theological text of his papacy, warning about the growing power of artificial intelligence and calling for stronger regulation of the technology.Released Monday, the 42,300-word encyclical “Magnifica Humanitas” marks Pope Leo’s most sweeping statement yet on the promise and dangers of AI, a topic he has repeatedly spoken about in the year since his election. Framed as an appeal for the defense of humanity in a rapidly automating world, the text urges governments, corporations, and individuals to slow the rate of technological development and ensure that AI remains subject to ethical and political oversight. He presented the encyclical at the Vatican alongside Christopher Olah, a co-founder of Anthropic, in a symbolic gesture of dialogue between Church leadership and the AI industry. The pope emphasized in the document that he is not opposed to innovation. Rather than rejecting technological progress, he wrote that “technology should not be considered, in itself, as a force antagonistic to humanity,” but instead must be guided by responsible and ethical use. But he warned that without stronger safeguards, artificial intelligence could deepen inequality, weaken human agency, and shift critical decisions increasingly out of human hands. “Calling for prudence, rigorous evaluation and even, at times, a slower pace in adopting AI does not mean opposing progress,” Leo wrote. “Instead, it is an exercise of responsible care for the human family.”The Pope has raised AI as a central concern since early in his papacy, telling the College of Cardinals shortly after his election that the Church would confront risks artificial intelligence posed to “human dignity, justice and labor,” a focus he has returned to in speeches throughout his first year as pontiff.Leo’s focus on AI is also reflected in his papal name itself, which he chose in reference to Pope Leo XIII, whose 1891 encyclical “Rerum Novarum” addressed the social consequences of the Industrial Revolution and established the foundation of modern Catholic social teaching on labor and technology. Leo XIV has drawn a direct comparison between the current moment of technological development and the one his most recent namesake confronted more than a century earlier, describing AI as ushering in a “new industrial revolution.”Here’s what to know about his first encyclical, and how it builds on those put forward by past popes.What is an encyclical?An encyclical is one of the most ...
