TL;DR
Pope Leo XIV released his first encyclical, Magnifica Humanitas, on May 25, setting out a Catholic social teaching response to AI. The Vatican presentation included Anthropic co-founder Christopher Olah, while OpenAI, Google DeepMind and xAI were absent from the announced AI speaker lineup, making the launch’s guest list part of the story.
Pope Leo XIV released his first encyclical, Magnifica Humanitas, on May 25, 2026, warning that AI power must serve human dignity and that technology is “never neutral”; the Vatican presentation included Anthropic co-founder Christopher Olah, while OpenAI, Google DeepMind and xAI were not named in the announced speaker lineup.
The encyclical, signed May 15 on the 135th anniversary of Rerum novarum, is Pope Leo XIV’s formal statement on safeguarding the human person in the age of artificial intelligence. The Vatican text frames AI as a matter of dignity, work, power, truth, freedom and war.
A Vatican News announcement said the May 25 presentation would include the Pope, Cardinals Víctor Manuel Fernández and Michael Czerny, theologians Anna Rowlands and Leocadie Lushombo, and Christopher Olah, Anthropic co-founder and head of AI interpretability research. The same notice did not list representatives from OpenAI, Google DeepMind or xAI.
The source material’s “empty chairs” argument rests on that contrast: Anthropic was visible at the launch, while other leading AI labs were not part of the official speaker roster. That does not establish that the Vatican endorsed Anthropic, but it affects how the event is read because the encyclical says technology reflects those who build, fund, govern and use it.
Why It Matters
The document matters beyond Catholic audiences because it puts the Vatican’s moral authority behind calls for public accountability in AI. Its concerns overlap with current disputes over model control, military use, labor automation, data access and the influence of private companies over public life.
The guest list also matters. A launch criticizing concentrated technological power can appear narrower when one safety-branded company is represented and other leading labs are absent from the visible lineup. That is an interpretation, not a confirmed Vatican policy choice, but it shapes the public meaning of the event.

Background
Leo XIV dated the encyclical May 15, the anniversary of Pope Leo XIII’s 1891 Rerum novarum, the landmark Catholic text on labor, capital and industrial society. Vatican News said Leo XIV drew a direct parallel between that industrial-era rupture and today’s AI systems.
Magnifica Humanitas argues that patents, algorithms, data, platforms and computing infrastructure can create new imbalances when held by a few. It also says AI systems do not possess conscience, warns that workers may be forced to adapt to machines, and rejects the use of algorithms for lethal or irreversible decisions.
“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, or were excluded from the May 25 presentation; the Vatican notices reviewed name Olah as the AI company speaker but do not explain the choices behind the lineup. It is also unclear how the encyclical will affect Catholic institutions, regulators or AI firms in practice.

What’s Next
The next phase is response: Vatican offices, bishops’ conferences, Catholic universities and policy forums will decide how to apply the encyclical to procurement, classroom use, labor policy, data rules and weapons systems. The public record will also be shaped by whether the Vatican engages a wider set of AI developers after the May 25 launch.

Key Questions
What did Pope Leo XIV release?
He released Magnifica Humanitas, his first encyclical, on May 25, 2026. The document applies Catholic social teaching to artificial intelligence and warns against concentrated technological power.
Was Anthropic the only AI company represented?
The official Vatican speaker list named Anthropic co-founder Christopher Olah. It did not list speakers from OpenAI, Google DeepMind or xAI.
Does the encyclical say AI is evil?
No. The document says technology is not inherently evil, but it argues that technology is not neutral because it reflects the people and institutions that design, fund, regulate and use it.
Why does the Rerum novarum anniversary matter?
Rerum novarum was the Church’s major response to industrial-era labor and capital conflicts. By signing Magnifica Humanitas on its 135th anniversary, Leo XIV framed AI as a comparable social rupture.
What remains unknown about the empty chairs?
The public notices do not say whether other AI labs were invited, declined, or were left out. That gap is why the launch’s optics remain part of the debate.
