Pope Leo XIV met with Anthropic co-founder Christopher Olah in the Vatican's Synod Chamber and announced that the Church would collaborate with Anthropic "to jointly guide humanity in the age of AI."

This marks the first time the highest authority in Catholicism has publicly established a partnership with a mainstream AI company. In his speech, the Pope directly stated that AI is changing the nature of warfare and that he was "entrusted to examine this enormous transformation with faith and clarity." The Vatican chose Anthropic as its partner, rather than OpenAI or Google. Anthropic's core concept is "constitutional AI," embedding safety and ethical constraints into its model training process. This logic naturally aligns with the religious institution's concern for human dignity and moral boundaries. Compared to its commercially driven competitors, Anthropic's positioning is clearly more likely to win the trust of conservative institutions.

While governments around the world are still debating AI regulatory frameworks, religious organizations with over a billion followers have already entered the fray.
