Pope Leo XIV and Anthropic Cofounder Partner on AI Ethics

Pope Leo XIV presented his first encyclical, "Magnifica Humanitas," at the Vatican on May 25, 2026, marking a historic collaboration by inviting Anthropic cofounder Christopher Olah to address the synod hall [1]. The 33-year-old tech leader, who identifies as an atheist, joined the Pope to advocate for a partnership between the Catholic Church and the technology industry to establish moral guardrails for artificial intelligence [1].

The encyclical serves as a critique of unchecked technological development, with the Pope specifically warning against the rise of autonomous weapons systems and biased algorithms that threaten access to healthcare and employment [1]. While the Vatican has historically remained insular, a senior official noted that inviting an external figure like Olah signals a new willingness to engage directly with the forces shaping the modern world [1].

Olah, whose company is estimated to be worth approximately $900 billion, argued that tech developers are often constrained by commercial incentives, geopolitical pressures, and the drive for research dominance [1]. He suggested that the Church can provide an essential, independent perspective to ensure that the benefits of AI are shared globally rather than concentrated in a few wealthy nations [1]. The partnership is not entirely new; Anthropic has previously included Catholic thinkers, such as Bishop Paul Tighe, in the development of its Claude Constitution [1].

During the presentation, the Pope emphasized that the Church does not seek to provide technical solutions but aims to offer a moral framework that recognizes the unique, irreplaceable nature of the human person [1]. Fr. Brendan McGuire, a Silicon Valley priest involved in the Vatican’s tech outreach, described the encyclical as a "prescient tool" for an industry that is increasingly concerned by its own rapid advancements [1].

The event concluded with a call for religious communities, scholars, and governments to act with urgency as AI development continues to accelerate [1]. Whether this moral dialogue can meaningfully influence the commercial and geopolitical incentives driving the tech sector remains the central question for the Church’s new diplomatic strategy.
