Pope Leo Signs His FIRST Encyclical

The most powerful religious institution on earth just told Silicon Valley that artificial intelligence needs to be disarmed, and it invited one of AI’s own architects to stand at the podium when it said so.

Story Snapshot

Pope Leo XIV signed his first encyclical, “Magnifica Humanitas,” on May 15, 2026, targeting AI’s threat to human dignity, warfare, and labor.
The document’s release date was chosen to coincide with the 135th anniversary of Leo XIII’s landmark labor encyclical, Rerum Novarum, signaling a deliberate historical parallel.
Breaking with Vatican tradition, the Pope personally presented the encyclical on May 25 alongside Christopher Olah, co-founder of the AI company Anthropic.
The Pope explicitly named Ukraine, Gaza, Lebanon, and Iran as evidence of AI-enabled warfare spiraling beyond human accountability.

A Pope Named for Labor Rights Targets the Machine Age’s Biggest Threat

The name Leo XIV was never accidental. When the new Pope chose it, Vatican observers immediately recognized the signal. Leo XIII authored Rerum Novarum in 1891, the Catholic Church’s foundational response to industrial capitalism and the exploitation of workers. Ascension Press confirmed that the signing of “Magnifica Humanitas” was deliberately scheduled to fall on the 135th anniversary of that document. ^[4] The message was unmistakable: the Church sees artificial intelligence as this century’s version of the industrial revolution, and it intends to respond with the same moral force.

Vatican News described the encyclical as focused on “safeguarding the human person in the time of artificial intelligence.” ^[5] That framing is precise and deliberate. The Church is not positioning this as a technology policy paper. It is positioning it as a defense of what it means to be human in an era when machines are beginning to make decisions that were once exclusively human, including decisions about who lives and who dies in combat zones.

War Zones as Exhibit A for Why AI Cannot Police Itself

Pope Leo did not speak in abstractions at La Sapienza University. He pointed directly at active conflicts. “What is happening in Ukraine, Gaza and the Palestinian territories, Lebanon and Iran illustrates the inhuman evolution of the relationship between war and new technologies into a spiral of annihilation.” ^[1] That is not diplomatic language. That is a sitting Pope telling the world that autonomous and AI-assisted weapons systems are already producing outcomes that no human being has fully chosen or fully controlled. The concern is not hypothetical. It is documented in real-time casualties.

The encyclical’s scope extends well beyond the battlefield. Pre-release commentary from Vatican-connected analysts indicated the document addresses moral, spiritual, and social dimensions of AI, including how the technology reshapes labor, truth, and the fabric of daily life. ^[2] The Vatican has been building toward this moment since at least 2016, when it began the Minerva Dialogues with Silicon Valley figures, and it issued the Rome Call for AI Ethics in 2020. ^[3] “Magnifica Humanitas” is not a reactive document. It is the culmination of a decade of institutional engagement with the technology industry.

Inviting the Industry Inside the Critique Is Either Brilliant or Dangerous

The most eyebrow-raising decision surrounding the encyclical’s launch was the invitation extended to Christopher Olah, co-founder of Anthropic, to speak at the Vatican presentation. ^[1] Anthropic builds the very category of large language model AI that the encyclical scrutinizes. Defenders of the choice will argue that genuine reform requires industry insiders at the table. Critics will argue that placing an AI company co-founder on the Vatican stage the day a moral critique of AI is released hands that industry a photo opportunity worth more than any lobbying campaign. Both readings are reasonable, and the tension between them is unlikely to resolve cleanly.

🚨 Breaking: Pope Leo XIV just dropped his first major encyclical and it's all about disarming AI.
In "Magnifica Humanitas," he warns AI must be freed from military, economic & power-driven competition. "To disarm does not mean rejecting technology, but preventing it from

What is harder to dismiss is the structural boldness of the presentation itself. America magazine reported that having the Pope personally present the encyclical breaks with precedent. ^[1] Popes typically release encyclicals through the Vatican press apparatus. Choosing to appear personally signals that Leo XIV considers this document urgent enough to stake his own presence on it. Whether secular governments, technology regulators, and corporate boardrooms treat Vatican moral teaching as binding is a separate question entirely. But the institution clearly believes the stakes are high enough to spend its credibility directly, and that judgment deserves to be taken seriously on its own terms.
