Pope Leo XIV has issued one of his strongest warnings yet about artificial intelligence, comparing its unchecked development to the biblical “Tower of Babel” and urging governments, companies and society to ensure the technology serves human dignity rather than undermining it.[2][3]

The warning came in his first major document focused on AI, which places the issue at the center of his papacy’s early agenda.[1][3] According to reporting on the Vatican’s message, the pontiff argued that rapid advances in artificial intelligence could intensify misinformation, deepen conflict and contribute to a world shaped more by power and control than by the common good.[1][3]

AI as a Test of Human Direction

In the document, Pope Leo framed AI not only as a technological question but as a moral and political one.[1][3] He urged leaders to slow the pace of development where necessary and to regulate the technology carefully so that it strengthens rather than weakens social justice, human dignity and freedom.[1][3]

That emphasis reflects a broader concern in the Vatican’s approach: that AI should not become a force that concentrates authority in the hands of a few powerful actors while ordinary people lose control over how the systems affect their lives.[3] The pope’s message also highlighted the risk of mass social control, suggesting that technology can shape behavior and opinion in ways that are not always visible to the public.[3]

The Biblical Warning of Babel

The “Tower of Babel” reference is especially striking because it evokes a story about human ambition, confusion and the limits of projects built without shared purpose.[2] In using that image, Pope Leo suggested that AI could become a symbol of technological overreach if it is developed without moral restraint or a clear commitment to the common good.[2][3]

He also offered a contrasting biblical image: the building of the walls of Jerusalem, which points to collective responsibility and the idea that people can build something good together when they act with purpose and care.[1] That contrast underscored his central argument that technology should be guided by human solidarity rather than by competition alone.[1][3]

War, Misinformation and the Common Good

The pope’s document does not treat AI as a distant or abstract concern.[1] It warns that the technology could be used to spread false information, sharpen conflict and even contribute to endless war if it is integrated into military and geopolitical competition without firm ethical limits.[1]

That concern appears to be one of the defining themes of the new pontificate. Reporting on the Vatican’s message says Leo has presented AI as a major issue for the church because it touches labor, daily life, human progress and the use of force in conflict.[1][3] He called for careful stewardship of these systems so they serve human beings rather than replace judgment, responsibility and conscience.[1][3]

A New Signature Issue for the Papacy

Pope Leo’s focus on artificial intelligence suggests the topic could become a signature issue of his leadership.[1] The Vatican’s framing positions the church as a moral voice in a global debate that is increasingly shaping law, economics, education and security.[3]

The pope’s intervention arrives at a time when governments around the world are still debating how best to regulate fast-moving AI systems.[3] His comments add spiritual and ethical weight to that discussion, especially for policymakers who are weighing innovation against risks to human agency, trust and social stability.[1][3]

For supporters of stricter oversight, the Vatican’s warning may reinforce the argument that AI needs stronger guardrails before it becomes embedded more deeply in public and private life.[1][3] For critics of heavy regulation, the pope’s remarks may still serve as a reminder that the debate is not only about efficiency or competition, but about what kind of society the technology is helping to build.[1][3]

In the end, Pope Leo’s message is straightforward: artificial intelligence must remain a tool in service of humanity, not a force that determines humanity’s future on its own.[3]
