In a landmark encyclical titled Magnifica Humanitas: On safeguarding the human person in the time of artificial intelligence, Pope Leo XIV has issued one of the most comprehensive warnings from a religious leader about the dangers of unchecked artificial intelligence. The 43,000-word document, released on Monday, frames AI as one of the greatest challenges facing humanity, calling for a coordinated global effort to "disarm" the technology before it dominates every aspect of human existence.
The encyclical, the first from Pope Leo since his election, builds upon concerns raised by his predecessor, Pope Francis, who had previously denounced what he called the "technocratic paradigm." The new document goes further, warning that AI risks lowering the threshold for armed conflict, transforming defense into mere threat prediction, and reducing victims to data points. In the economic sphere, the Pope argues that AI could concentrate power among a small number of tech firms, disrupt labor markets, and exacerbate inequality.
The timing of the encyclical is notable, coming three years after a viral deepfake image of Pope Francis wearing a white Balenciaga puffer coat fooled millions of people online. That incident, created by a Chicago construction worker using an AI image generator, became a symbol of the new era of misinformation. The man behind the image, Pablo Xavier, later expressed surprise at its reach and called for regulation. The encyclical directly references the dangers of manipulated images and videos but notes that the most damaging deepfakes have so far remained limited in number.
Pope Leo’s document also touches on the psychological impacts of AI on vulnerable users, the environmental cost of massive data centers, and the rise of cyber attacks. It warns that technologies designed to mimic human interaction can weaken the social fabric and erode authentic relationships. The Pope writes, "Humanity – in all its grandeur and woundedness – must never be replaced or surpassed. We can embrace the technological progress that alleviates suffering and unlocks new possibilities, provided that we do not abandon the very essence of our humanity, namely the capacity for relationship and love."
Interestingly, the encyclical stops short of addressing the most extreme hypotheticals, such as the emergence of artificial general intelligence (AGI) or superintelligence. Some researchers believe these could pose an existential risk to humanity. The document also does not discuss the rise of techno-religious movements that view AGI as a godlike entity. However, it implicitly rejects the notion that AI could ever achieve consciousness or be worthy of worship. The Pope states, "Human fulfilment does not arise from a technological divinization, but through God's grace received in Christ."
Will Jones, religious outreach lead at the Future of Life Institute, interprets this as a clear rebuke to AI companies pursuing superintelligence. "This is a direct rebuke of the leading AI companies’ stated goal of creating smarter-than-human superintelligence," Jones said. "It is also an acknowledgement that AI tools, not autonomous general-purpose systems, are the key to a flourishing human future."
The encyclical arrives as some religious institutions are already experimenting with AI. In Switzerland, a chapel in Lucerne installed an "AI Jesus" in 2024, allowing parishioners to confess their sins to a digital avatar. Two-thirds of early users reported a spiritual experience. In South Korea, a Buddhist temple initiated an AI-powered robot monk in an ordination ceremony. A California startup named Just Like Me offers "personal relationships with Jesus" through video calls at $1.99 per minute, using an AI model trained on the King James Bible.
Not all clergy are alarmed. Father Josef Wieneke of St Matthias Catholic Church in Berlin told The Independent earlier this year that nothing could replace the physical and spiritual role of a pastor. "The Catholic sacraments cannot be performed by a computer. They only work face to face," he said. The encyclical echoes this sentiment, emphasizing that technological progress must never allow the heart to regress. It cites "martyrs of everyday life" as examples of humanity's capacity for love and worship.
Despite the warnings, all major AI firms continue to pursue ever more powerful models. Chris Olah, co-founder of Anthropic, responded to the encyclical with a remark that highlighted the reverence many tech leaders have for AI. "What has grown is far more subtle, odd, and beautiful than science fiction prepared us for," Olah said. He described AI systems as "made from us, from our words – and, as the Holy Father observes, they remain in important ways mysterious even to those of us who train them."
The document’s call for regulation is not new. Since the Pope in a puff coat incident, multiple governments have proposed AI laws, though comprehensive international agreements remain elusive. The European Union passed its AI Act in 2024, and the United Nations has held high-level meetings on the topic. However, the Vatican’s moral authority could add weight to the push for global rules. The encyclical is addressed to all people, not just Catholics, urging a collective response to ensure that AI serves humanity rather than subjugates it.
Pope Leo’s encyclical also underscores the environmental toll of AI. Training large models consumes massive amounts of energy and water, contributing to climate change. The Pope calls for sustainable development and ethical investment in technology. He warns against a "technological solutionism" that believes every problem can be solved with a new gadget or algorithm.
The document reflects a deep concern for the marginalized. AI systems often replicate and amplify existing biases, potentially discriminating against the poor and vulnerable. The Pope insists that any AI deployment must be evaluated for its impact on human dignity. "We cannot accept a future where the most vulnerable are left behind or where human worth is measured by utility," he writes.
In the realm of warfare, the encyclical notes that autonomous weapons systems could make conflict more likely by lowering the human cost of starting a war. "Transforming defence into threat prediction and thus reducing victims to data" is a dangerous path, Pope Leo argues. He calls for a ban on lethal autonomous weapons, echoing similar appeals from human rights groups and some governments.
The encyclical also touches on education. AI is already reshaping how children learn, raising questions about attention spans, critical thinking, and reliance on algorithms. The Pope advocates for an education that fosters creativity, empathy, and moral reasoning alongside technical skills.
Perhaps the most poignant part of the document is its reflection on love. The Pope writes that human beings are not merely rational animals but relational creatures made for love. AI, no matter how advanced, can never replicate the self-giving love that lies at the heart of Christian faith. "Technological progress without allowing the heart to regress" is the balance he seeks.
The encyclical’s publication has prompted reactions from both tech executives and theologians. Some see it as a timely intervention, while others criticize it as too vague. But the Vatican’s message is clear: the future of humanity must not be left to engineers and investors alone. Moral and spiritual traditions have a vital role to play in shaping our relationship with intelligent machines.
As the world navigates the age of AI, the Pope’s words offer a framework for hope. He does not reject technology outright but calls for its subordination to higher values. The encyclical ends not with a conclusion but with a prayer. "May the Holy Spirit guide our hearts and minds, so that we may harness the gifts of creation for the good of all, without losing sight of the eternal love that calls us beyond the machine."
