TL;DR
Pope Leo XIV released Magnifica humanitas on May 25, 2026, making artificial intelligence the subject of his first encyclical and linking AI governance to human dignity, labor, truth and war. The Vatican confirmed Anthropic co-founder Christopher Olah was among the presentation speakers; OpenAI, Google DeepMind and xAI were not listed. It remains unclear whether those companies were invited, declined or were outside the Vatican’s planned format.
Pope Leo XIV released his first encyclical, Magnifica humanitas, on May 25, 2026, placing artificial intelligence at the center of Catholic social teaching and drawing scrutiny to the Vatican’s decision to present the document with Anthropic co-founder Christopher Olah among the speakers while OpenAI, Google DeepMind and xAI were not named on the official speaker list.
Confirmed: The Holy See Press Office said Magnifica humanitas was signed on May 15, 2026, the 135th anniversary of Pope Leo XIII’s Rerum novarum, and released on May 25. The document is subtitled On Safeguarding the Human Person in the Time of Artificial Intelligence and places AI inside the Church’s social teaching on power, labor, rights, the common good and peace.
Confirmed: Vatican News said the Pope was present in the Synod Hall and that speakers included Cardinal Victor Manuel Fernandez, Cardinal Michael Czerny, Anna Rowlands, Leocadie Lushombo and Christopher Olah, an Anthropic co-founder and interpretability researcher. The Vatican materials reviewed do not list OpenAI, Google DeepMind or xAI among the speakers.
The core argument is that AI should not be treated as an outside force acting on society by itself. Leo says human choices, money, law and use shape technology, which makes AI governance a moral and political issue as well as a technical one. The “empty chairs” framing is an interpretation of the launch, not a separate Vatican announcement: the confirmed fact is the public speaker list; the disputed point is what that list signals about who the Church chose as its AI interlocutors.
Why It Matters
Encyclicals are among the highest-profile teaching documents issued by a pope, and first encyclicals often set a tone for a pontificate. By using that form for AI, Leo moved the debate beyond product safety and economic competition into questions of who holds power, whose dignity is protected and whether machines are being used to lower the barrier to violence.
The invitation list matters because the document warns against power concentrated in the hands of a few. If only one frontier lab is visibly in the room, especially a company closely identified with AI safety, critics can read the launch as narrowing the target of a document that is aimed at a much larger industry. That reading is an interpretation, but it flows from the encyclical’s own claim that technology reflects the people and institutions behind it.

Background
Leo’s timing was deliberate. Pope Leo XIII’s Rerum novarum in 1891 addressed labor and capital during the industrial age; Leo XIV signed Magnifica humanitas on that encyclical’s 135th anniversary and frames AI as a comparable social break.
The new text has five chapters and returns to a repeated concern: AI systems may be built, financed and governed by a small set of private actors with reach beyond many states. It also addresses work, truth, surveillance, discrimination, military AI and the limits of claims that machines can imitate human conscience or empathy.
“technology is never neutral, because it takes on the characteristics of those who devise, finance, regulate and use it.”

What Remains Unclear
It remains unclear whether OpenAI, Google DeepMind or xAI were invited, declined, attended in another capacity or were not sought for the event. The Vatican’s public materials identify Olah and several Church and academic speakers, but they do not explain how AI-side participation was chosen.
It is also too early to know whether the encyclical will affect AI law, company policy or military AI procurement. Its immediate effect is clearer in moral and political language: it gives bishops, Catholic universities, policymakers and civil society groups a papal text to cite in debates over AI power.

What’s Next
Next, Vatican offices, bishops’ conferences, Catholic universities and AI policy groups are likely to test how the encyclical applies to regulation, workplace automation, education, surveillance and weapons systems. AI companies may face renewed questions about whether they will engage the Vatican’s criticism directly, and whether future Church convenings will include a wider set of labs than the May 25 launch showed publicly.

Key Questions
What is Magnifica humanitas?
It is Pope Leo XIV’s first encyclical, released May 25, 2026, on safeguarding the human person in the time of AI. The Holy See says it was signed May 15, the anniversary of Rerum novarum.
Did the Pope condemn all AI?
No. The document treats technology as capable of helping people, but says AI is shaped by builders, funders, regulators and users. Its warning is aimed at domination, exclusion, worker harm, surveillance and war.
Who from the AI industry was at the launch?
Vatican News listed Christopher Olah, co-founder of Anthropic and an AI interpretability researcher, among the speakers. Public Vatican materials reviewed do not list OpenAI, Google DeepMind or xAI as speakers.
Why are the missing companies part of the story?
Because the encyclical criticizes concentrated technological power. The absence of several leading labs from the public speaker list has been read by commentators as an optics problem, though the Vatican has not said whether those firms were invited.
What happens now?
The document is likely to be used in Church teaching, university debates and policy discussions about AI safety, labor, data systems and autonomous weapons. Its practical effect depends on whether public officials and companies respond.
