TL;DR
Pope Leo XIV signed Magnifica humanitas on May 15, 2026, and released it May 25, casting artificial intelligence as a defining moral and social challenge for the Church. The launch drew scrutiny because Anthropic’s Chris Olah was present, while OpenAI, Google DeepMind and xAI were absent, according to the source material.
Pope Leo XIV released Magnifica humanitas, his first encyclical, on May 25, 2026, framing artificial intelligence as a major test for Catholic social teaching and warning that technology is shaped by those who build, fund, regulate and use it.
The document was signed on May 15, 2026, the 135th anniversary of Pope Leo XIII’s 1891 encyclical Rerum novarum, according to the source material. By choosing that date and the Leonine name, Leo XIV linked the AI era to the Industrial Revolution, when the Church addressed labor, capital and the dignity of work.
The encyclical’s central argument is that AI is not hostile to humanity by nature, but cannot be treated as value-free. It warns that AI power may become concentrated “in the hands of only a few” and says a more moral AI is insufficient if its moral frame is set by a small group of companies or institutions.
Leo XIV presented the encyclical personally at the Vatican, a detail the source material says was unusual because popes often delegate such presentations. Among the AI experts present was Anthropic co-founder Chris Olah. The source material says representatives from OpenAI, Google DeepMind and xAI were not present.
Technology is never neutral — and neither were the empty chairs
Pope Leo XIV’s first encyclical casts AI as this century’s Rerum novarum moment. He presented it personally — with Anthropic’s co-founder in the room. OpenAI, Google DeepMind & xAI were not. For a “broadside against AI companies,” that guest list is itself an argument.
A Rerum novarum for the age of AI
The signing date wasn’t incidental. Leo XIV chose the 135th anniversary of Leo XIII’s 1891 encyclical — and, by taking the Leonine name, cast himself as the pope who answers AI as Leo XIII answered industry.

Five chapters, one worry: concentration
The recurring anxiety is that AI’s power lands “in the hands of only a few” — and that a more moral AI isn’t enough “if that morality is determined by a few.”
A dynamic doctrine, faithful to the Gospel
Situating AI in the Church’s social teaching — the living tradition from Rerum novarum onward.
Foundations & principles
Human dignity that is “neither acquired nor earned”; the common good; the universal destination of goods — tech must not be held by a few.
Technology & dominance
The “technocratic paradigm.” AI can simulate a person but has no moral conscience or empathy. Calls to “disarm” AI from the logic of competition.
Safeguarding humanity: truth, work, freedom
The “new ways” of working aren’t always better; AI too often makes workers adapt to machines. Warns of an “architecture of visibility.”
The culture of power & the civilization of love
The hardest charge: “no algorithm can make war morally acceptable.” Argues even “just war” theory must now be overcome.

Who was in the room — and who should have been
Leo XIV presented the encyclical personally (popes usually delegate). Among the AI experts: Anthropic’s Chris Olah. The other frontier labs? Empty chairs. Tap each seat.

A broadside delivered to one delegate
The Washington Post read the encyclical as one that “fires a broadside against AI companies.” A reckoning aimed at an industry is weakened when one member — the most safety-branded one — is present to receive it.
The encyclical’s hardest charge is about AI and war — and it implicates the labs that weren’t there.
Its most uncompromising passages condemn AI-enabled weapons and the lowering of the threshold for violence. But that lands hardest on the defense-entangled players and the leaders most explicit about military & geopolitical ambitions — not the lab that showed up.
Account vs. anoint
One sympathetic guest tilts it from “the Church holding the industry to account” toward “the Church beside its preferred firm.”
Concentration, again
A text whose deepest fear is power “determined by a few” launched by elevating one company as chosen interlocutor.

Two things are true at once
The criticism is of the exclusivity, not the inclusion. Olah in the room was fitting; Anthropic alone was incomplete.
The most significant AI reckoning yet by a global moral institution
It grounds a critique of concentration, dehumanized work & algorithmic warfare in a tradition stretching back to 1891. Its core insight — technology carries its makers’ values — is exactly the right place to start.
A broadside should be delivered to the industry, not its most palatable face
The choice to present alongside Anthropic alone — defensible, probably well-intentioned — undercut the encyclical’s own insight about whose values get associated with the message.
A beginning, not an endpoint
The same month, Leo XIV approved an Interdicasterial Commission on Artificial Intelligence — a standing body with room for many voices over time. If it brings the whole industry into uncomfortable dialogue, the narrow first launch reads as a first step, not a pattern.
Why It Matters
The encyclical matters because it places AI within the Church’s social doctrine rather than treating it only as a technical or business issue. Its focus is not only whether AI systems behave safely, but who controls them, who benefits, who bears the costs and whether human dignity is reduced by automated systems.
The guest list also matters. If the encyclical’s argument is that technology reflects the character and incentives of its makers, then the choice of which AI builders appear beside Church officials carries meaning. The source material argues that Anthropic’s presence was fitting because of its safety-oriented public profile, but that its presence alone made the launch appear narrower than the document’s industry-wide critique.
Background
Magnifica humanitas is described in the source material as a five-chapter document that covers Catholic social teaching, human dignity, the common good, technology and dominance, truth, work, freedom, war and the concentration of power.
The document’s historical echo is central to its framing. Rerum novarum responded to industrial labor and capital in 1891. Magnifica humanitas, by contrast, addresses AI-driven concentration, dehumanized work, surveillance-like systems and algorithmic warfare.
The source material says The Washington Post read the encyclical as one that “fires a broadside against AI companies.” That interpretation is attributed reporting, not a confirmed Vatican description of the document’s purpose.
What Remains Unclear
It is not clear from the source material whether OpenAI, Google DeepMind or xAI were invited and declined, were not invited, or were absent for other reasons. It is also not clear whether the Vatican plans further meetings with other AI companies, regulators, labor groups or civil society organizations after the encyclical’s release.
What’s Next
The next question is how the Vatican follows the document. Watch for whether Church officials broaden talks beyond Anthropic, whether major AI labs respond publicly, and whether Catholic institutions use the encyclical to shape policy positions on AI governance, labor protections and military use.
Key Questions
What is the actual news development?
Pope Leo XIV released his first encyclical, Magnifica humanitas, on May 25, 2026, after signing it on May 15. The document addresses artificial intelligence through Catholic social teaching.
Why is Anthropic part of the story?
Anthropic co-founder Chris Olah was present at the Vatican presentation, according to the source material. The absence of OpenAI, Google DeepMind and xAI made the event’s optics part of the discussion.
What does the encyclical say about AI?
It says technology is not inherently evil, but is never neutral. It warns about concentrated control, machine-shaped work, simulated personhood, visibility systems and AI’s role in warfare.
What is confirmed and what is unclear?
The release date, signing date, core themes and Anthropic’s presence are reported in the source material. It remains unclear whether other frontier AI labs were invited, declined or were excluded.
Why does this matter outside the Catholic Church?
The encyclical adds a major religious and ethical voice to debates over AI governance, corporate power, labor, surveillance and military use. Its influence may depend on whether the Vatican turns the text into sustained engagement with governments, companies and affected communities.
