Pope Leo XIV and Anthropic Co-Founder Discuss AI Ethics

Pope Leo XIV and Anthropic co-founder Christopher Olah appeared together at the Vatican on May 25, 2026, to present the Pope's first encyclical, Magnifica Humanitas [1]. The event marked a rare collaboration between the Catholic Church and a major technology leader, aimed at establishing moral safeguards for the rapid advancement of artificial intelligence [1].

Key takeaways

• Pope Leo XIV’s encyclical, Magnifica Humanitas, calls for government regulation of AI and warns against the concentration of power in the digital sector [1].
• Christopher Olah, co-founder of the AI firm Anthropic, argued that tech companies require external, moral voices to critique their work and ensure global equity [1].
• The Vatican has previously engaged with Anthropic, including the company’s inclusion of Catholic thinkers in the development of its Claude Constitution [1].
• Anthropic is currently involved in legal action against the U.S. administration following orders for agencies to cease using the company's technology [2].

A New Dialogue on Technological Ethics

The presentation of the encyclical in the Vatican’s Synod Hall brought together an unlikely partnership between the 33-year-old atheist tech leader and the pontiff [1]. During the event, Olah emphasized that the tech industry is driven by commercial incentives, geopolitical pressures, and ambition, necessitating "earnest, thoughtful critics" who operate outside those influences [1]. He noted that because AI development is currently concentrated in a small number of wealthy nations, the Church’s involvement is vital to ensure that the benefits of the technology are shared globally [1].

Pope Leo XIV stated that while the Church does not possess technical expertise, it offers a "wisdom concerning the human" that is necessary to address the risks posed by unchecked development [1]. He specifically highlighted concerns regarding autonomous weapons systems and algorithms that may perpetuate injustice or block access to essential services like healthcare and employment [1]. The Pope’s document draws parallels to the 1891 encyclical Rerum Novarum, which addressed the social impacts of the Industrial Revolution, suggesting that the AI era presents similar existential questions for humanity [2].

Why it matters

The collaboration reflects a growing urgency within the Vatican to influence the trajectory of artificial intelligence before it becomes impossible to govern [1]. Fr. Brendan McGuire, a Silicon Valley priest involved in the Church's tech outreach, noted that industry leaders themselves have expressed fear regarding their own creations, making the partnership a moral imperative [1].

The meeting also occurs against a backdrop of significant political tension for Anthropic. The company is currently suing the U.S. administration after being penalized for refusing to grant the military unrestricted access to its AI technology [2]. As the Church seeks to provide a moral framework for these tools, the Vatican’s engagement with Anthropic signals a shift toward more direct participation in global dialogues regarding the future of human dignity in the digital age [1].
