Pope Leo XIV · Robert Francis Prevost
The first American-born pope took the name Leo in part as a deliberate echo of Leo XIII, whose 1891 encyclical Rerum Novarum framed the labour question at the dawn of industrialism. Leo XIV has named artificial intelligence one of the defining moral challenges of the century, explicitly drawing the analogy between the displacement faced by 19th-century industrial workers and the displacement now confronting knowledge workers.
The Pope's first Encyclical Letter, Magnifica Humanitas, names artificial intelligence as a defining moral challenge of the century and frames three areas as requiring protection: truth against manipulation, work against dehumanization, and freedom against digital dependency. The Encyclical's organizing line, a "Civilization of Love" built on justice, brotherhood, and dialogue, is positioned against what the document calls a "culture of power."
At the Synod Hall on 25 May 2026, the Vatican Dicastery for Promoting Integral Human Development hosted Chris Olah, Anthropic co-founder, for a presentation on AI alignment and interpretability research. The conversation is part of a longer Vatican dialogue with frontier AI labs that includes the Pontifical Academy for Life's working group on AI and human integrity, and the Rome Call for AI Ethics, originally signed in 2020 and now counting Microsoft, IBM, Cisco, the UN's FAO, and the Italian government as signatories.
The institutional Church's posture is not anti-technology. It is anti-displacement-without-recourse. AI is a tool that must be made to serve persons rather than displace them; the Vatican is willing to use its convening power to put that demand into the room with the labs.
