Pope and Anthropic co-founder forge unlikely AI ethics alliance at Vatican

On May 25, inside a Vatican auditorium filled with cardinals, theologians, and journalists, Pope Leo XIV stood to unveil Magnifica Humanitas, an encyclical on artificial intelligence and human dignity. Beside him sat Christopher Olah, a 33-year-old atheist and co-founder of Anthropic, one of the world's most valuable AI companies. The image was jarring in its improbability: the Catholic Church and Silicon Valley, not sparring across ideological lines, but appearing to work in concert.

For years, the Vatican had been among the world's most vocal institutional critics of artificial intelligence. Church leaders had warned repeatedly that AI threatened human dignity, concentrated power in the hands of a few corporations, and posed environmental risks. Just days before this May 25 event, the Vatican had established its own study group to investigate the technology's dangers. That the Church would then invite a major AI executive to share the stage at the encyclical's launch suggested something had shifted.

Magnifica Humanitas itself carried a forceful message. The document warned that unchecked technological development was intensifying crises across society. It singled out the growing concentration of digital power and called for governments to regulate AI companies far more aggressively than they currently do. But the encyclical's text was only half the story. The real news was the partnership being announced in real time, on stage, before the world's cameras.

Olah did not shy from acknowledging why such an alliance mattered. He said plainly that the people building AI cannot solve its ethical problems alone. Tech leaders, he argued, need voices from outside the industry—people untouched by the financial incentives, competitive pressures, and geopolitical rivalries that drive development. Anthropic itself is valued at nearly $900 billion, a figure that underscores just how much money and ambition are now concentrated in AI. Those same forces, Olah suggested, are precisely why external moral scrutiny is essential. "We need informed critics who will tell the labs when we are failing," he said. "We need moral voices that the incentives cannot bend." It was a striking moment: an AI executive effectively asking the Church to function as a watchdog over his own industry.

Olah also raised a second concern that seemed to resonate with the Vatican's own priorities. AI development, he noted, is concentrated in a small number of wealthy nations and companies. The benefits of the technology, he argued, must be distributed globally—a question of justice that the Church has historically refused to ignore. The Vatican, for its part, appeared to recognize that moral criticism from the sidelines was no longer sufficient. By standing alongside Olah, Pope Leo XIV signaled that the Church intended to have a voice in shaping AI's future, not merely commenting on it from a distance. The pope said he accepted the invitation "to walk together, to listen and to speak and together to find the way for humanity, in this time of artificial intelligence." He called their public dialogue "a great sign of hope."

Yet the partnership raises unresolved questions. Anthropic had not signed an earlier Vatican-backed pledge on ethical AI, and the company's selection for such a prominent role at the encyclical's launch remains unexplained. However, connections between the two institutions already existed beneath the surface. Anthropic has consulted with Catholic thinkers while developing the "Claude Constitution," the ethical framework that guides its AI models. Bishop Paul Tighe, from the Vatican's Dicastery for Culture and Education, was among those contributors. The alliance, then, was not entirely without precedent—but its public unveiling marked a new phase in how the Church and AI companies might engage with each other's concerns.
