Vatican Hosts Anthropic Co-Founder for AI Encyclical Launch

Pope Leo XIV will present his first papal encyclical on artificial intelligence, titled "Magnifica Humanitas," at the Vatican on May 25, the Vatican said and Bloomberg reported. The Vatican described the document as addressing "the protection of the human person in the age of artificial intelligence," according to PBS/AP and Euronews. Christopher Olah, co-founder of Anthropic, is listed among lay speakers at the launch, per Bloomberg, PBS/AP and Fortune. The Vatican also approved a new internal AI commission on May 16, a move reported by Fortune and Euronews that the Holy See says will coordinate AI-related work across multiple Vatican bodies.

Anthropic is publicly known for framing its work around safety and risk mitigation, a characterization found in PBS/AP and Euronews reporting. The company produces the Claude family of models, and public coverage frames Anthropic as one of the firms emphasizing interpretability and deployment constraints. The presence of a prominent machine learning researcher on a papal stage highlights the Vatican choosing technical expertise for a policy-focused document, rather than exclusively theological or pastoral voices.

Multiple outlets place the Vatican event against a backdrop of heightened friction between Anthropic and the U.S. government. PBS/AP and Euronews report that the Trump administration in February ordered U.S. agencies to stop using Anthropic technology and imposed other sanctions; Anthropic is reported to be pursuing legal action contesting aspects of that government response. Public reporting frames the encyclical and the new Vatican commission as part of a broader set of nonstate and multilateral actors engaging in AI governance debates, alongside national regulators and industry self-regulation efforts.

The New York Post reports that Christopher Olah has described himself as an "atheist" and recounts critical blog posts he has written about religion. That characterization appears in tabloid reporting; major outlets covering the encyclical launch (Bloomberg, PBS/AP, Euronews, Fortune) note Olah as a technical speaker but do not foreground his personal beliefs.

Observers following AI governance should track how the encyclical frames ethical tradeoffs such as human dignity, labor, and military uses of AI, and whether the Vatican issues operational recommendations for institutions. Monitor statements from the Vatican commission once it publishes guidance, and watch for any formal responses from U.S. agencies or lawmakers given the prior February restrictions reported by PBS/AP and Euronews. Also watch for whether Anthropic or other firms publish accompanying technical notes or safety commitments around the launch.

For practitioners, the episode exemplifies growing overlap between technical experts and nontechnical norm setters. Companies that emphasize safety are increasingly invited into political and ethical fora, which can raise legal and reputational knot-tying when firms are simultaneously contesting government actions. Industry observers will likely interpret the Vatican event as part of a diversified governance ecosystem where religious institutions, courts, regulators, and firms all shape norms around AI use.
