The Vatican Drops Its AI Encyclical — And It's a Geopolitical Event

TL;DR

• Pope Leo XIV releases Magnifica Humanitas, the first papal encyclical on AI, today — May 25 — at a formal Vatican launch the Pope himself will attend, breaking centuries of tradition.
• Anthropic co-founder Chris Olah will speak at the launch. Anthropic is currently suing the Trump administration, which in February ordered all US agencies to stop using its technology.
• The encyclical is expected to condemn AI in warfare, address workers' rights in the age of automation, and frame AI as the Industrial Revolution of our time — requiring the same moral reckoning.
• This is not a symbolic document. It carries teaching authority over 1.4 billion Catholics and arrives at a moment when banks are cutting thousands of jobs to AI, autonomous weapons are proliferating, and three AI giants are racing toward the largest IPOs in history.

What Happened

On Monday, May 25, Pope Leo XIV will personally present Magnifica Humanitas ("Magnificent Humanity") at the Vatican — the first papal encyclical dedicated entirely to artificial intelligence. The document was signed on May 15, deliberately chosen as the 135th anniversary of Rerum Novarum, Pope Leo XIII's landmark encyclical on workers' rights during the Industrial Revolution.

The Pope will be joined by an unusually high-profile panel: two of the Vatican's top cardinals (doctrine chief Cardinal Víctor Manuel Fernández and development chief Cardinal Michael Czerny), theologians Anna Rowlands and Leocadie Lushombo, and — most strikingly — Chris Olah, co-founder of Anthropic. The Vatican Secretary of State, Cardinal Pietro Parolin, will offer a conclusion, and Leo will deliver a speech and final blessing.

Popes do not normally present their own encyclicals. That task falls to cardinals and press officials. Leo's decision to appear in person, in the main Vatican auditorium rather than the press room, signals that this is not routine teaching — it is a deliberate intervention.

The Vatican statement said the text addresses "the protection of the human person in the age of artificial intelligence." Sources indicate it will decry AI in warfare and address how the technology is challenging workers' rights. Leo previewed his thinking in a speech at Sapienza University in Rome last week, where he described "the inhumane evolution of the relationship between war and new technologies in a spiral of annihilation," citing conflicts in Ukraine, Gaza, Lebanon, and Iran.

What It Actually Means

The encyclical matters for three reasons, none of which are primarily theological.

First, it is a geopolitical move dressed in vestments. Leo is the first American pope. He has already angered President Trump by criticising the US-Israeli war on Iran. The Trump administration ordered all federal agencies to stop using Anthropic's technology in February and imposed penalties after the company refused to allow unrestricted military use of its AI. Anthropic is now suing the administration for illegal retaliation.

By placing Olah on stage at the Vatican, Leo is not merely consulting a technical expert. He is providing moral cover to the AI company most visibly resisting the administration's push to weaponise the technology. The encyclical gives Catholic politicians, military officials, and voters a doctrinal framework to oppose autonomous weapons and AI-driven surveillance — and it does so with the authority of a document that 1.4 billion people are expected to take seriously.

Second, it frames AI as a labour crisis, not just a safety crisis. Leo signed the document on the anniversary of Rerum Novarum, which established the Church's modern teaching on workers' rights. That is not subtle. The encyclical is expected to offer the Church's fullest guidance on workers' rights in decades. This lands in the same week that Standard Chartered announced it would cut over 7,000 jobs and replace "lower-value human capital" with AI, and HSBC's CEO told staff not to "fight AI." The encyclical provides a counter-narrative: that the value of human work is not reducible to efficiency metrics.

Third, it legitimises AI safety as a moral category, not just a technical one. Anthropic has positioned itself as the safety-first AI company. Its presence at the Vatican — and the Pope's implicit endorsement of its approach — elevates "AI safety" from a Silicon Valley marketing term to a matter of Catholic social teaching. This will not go unnoticed in boardrooms or in Washington.

What This Isn't

This is not the Catholic Church "endorsing" Anthropic or any AI company. The encyclical is a teaching document, not a product launch. Olah was invited because of his research into neural network mechanisms, not because the Vatican is picking winners in the AI race.

It is also not a Luddite document. Leo has spoken repeatedly about AI's potential benefits. The encyclical is expected to address how AI can serve human dignity, not just threaten it. The framing is protection of the human person, not rejection of technology.

Stakeholder Landscape

Directly affected: The 1.4 billion Catholics who will receive this as formal teaching. Catholic politicians and military leaders who must now reconcile AI policy with doctrine. Anthropic, which gains moral legitimacy at a moment of legal conflict with the US government.

Second-order affected: Every AI lab building toward AGI. The encyclical provides a vocabulary for critics and regulators. The Trump administration, which now faces a moral counterweight to its push for unrestricted military AI. Workers in industries facing AI-driven automation, who now have a doctrinal document to cite.

Not affected, despite the noise: Day-to-day AI product development. The encyclical will not change what your chatbot does tomorrow. It is a framework document, not a regulation.

Cross-Layer Implications

The encyclical connects threads that usually operate in separate silos:

• Security: Leo has explicitly condemned AI in warfare. This puts pressure on NATO members — many of whom have Catholic populations — to develop AI weapons policies consistent with the encyclical's framework.
• Commercial: The three-way IPO race between SpaceX/xAI, OpenAI, and Anthropic now has a new variable. Anthropic's association with the Vatican may appeal to ESG-conscious investors and funds with Catholic institutional clients.
• Regulatory: The EU AI Act is already in force. The encyclical provides moral reinforcement for its restrictions on high-risk AI applications, particularly in warfare and surveillance.
• Labour: The timing with StanChart's 7,000 job cuts and HSBC's "don't fight AI" messaging is not coincidental. The encyclical arrives at the precise moment when AI-driven job displacement is moving from forecast to fact.

What This Means for You

If you work in AI policy or governance: Read the encyclical when it is published. It will be cited in regulatory proceedings, corporate ethics policies, and political debates for years. Understanding its framework is now a professional requirement, not a matter of personal interest.

If you work at an AI company: Expect your ethics and safety teams to reference this document. If your company does not have an ethics and safety team, the encyclical is one more reason to build one.

If you are a Catholic in a position of authority — military, corporate, or political: This document carries teaching weight. You will be asked how your decisions align with it. Prepare that answer.

If you are none of the above: The encyclical matters because it shifts the Overton window on AI regulation. When the Vatican says "AI in warfare is a moral crisis," it becomes harder for governments to treat it as a purely technical procurement question.

Uncertainty Ledger

• The full text of Magnifica Humanitas has not been released. Analysis is based on Vatican statements, Leo's prior speeches, and sourced reporting. The encyclical may contain positions that surprise.
• The Trump administration's response is unknown. The White House could ignore the document, attack it, or — less likely — engage with it.
• Anthropic's legal conflict with the administration is ongoing. The Vatican's implicit support may strengthen Anthropic's position, but it does not resolve the legal dispute.
• The encyclical's long-term influence depends on how aggressively bishops and Catholic institutions incorporate it into their teaching and advocacy. Papal documents can be transformative or ignored; it depends on implementation.

Bottom Line

Pope Leo XIV's AI encyclical is the most significant institutional moral intervention in the technology's history. It arrives at a moment when AI is simultaneously producing trillion-dollar IPOs, eliminating thousands of jobs, and being deployed in active war zones. By standing beside an AI safety researcher whose company is being sued by the White House, Leo has made clear that this is not a document about abstract ethics — it is about power, and about which powers get to define what AI is for. The encyclical will not stop a single line of code from being written. But it will change the terms under which that code is judged.
