The church steps into the AI debate: What the Pope’s first encyclical means

Pope Leo XIV issued his first encyclical, *Magnifica Humanitas*, on May 25, 2026, addressing the ethical and societal challenges posed by artificial intelligence. The 42,000-word document urges global regulation of AI, arguing that its current development benefits a small elite while exposing the public to risks like epistemic, economic, and political asymmetry. The Pope framed AI as a tool that encodes values and visions of humanity, questioning whether its trajectory serves collective well-being or corporate interests. The encyclical was signed on May 15, 2026—the 135th anniversary of Pope Leo XIII’s *Rerum Novarum*, which addressed industrialization’s impact on workers. Pope Leo XIV’s timing reflects the Church’s concern that AI’s rapid advancement threatens human dignity, identity, and moral values. The document emphasizes that technology is never neutral, as its designers and financiers embed their own agendas into AI systems. In an interview with Franciscan Sister Ilia Delio, a theologian at Villanova University, the significance of the encyclical was explored. Delio noted that the Church’s response to AI is timely, given its pervasive influence on daily life and its potential to reshape human values. She acknowledged the Pope’s concern about AI’s unchecked power but suggested differing views on how to balance human-AI relationships, calling it both a theological and anthropological issue. Delio highlighted the Pope’s call for slowing AI development, citing broader societal unease, particularly among younger generations, about its rapid integration. While she agreed with the Pope’s ethical concerns, she questioned whether regulation alone could address the deeper philosophical questions about AI’s role in society. The encyclical marks a bold intervention by the Vatican into a debate traditionally dominated by policymakers and technologists. Critics and supporters alike may debate the Pope’s proposed solutions, but *Magnifica Humanitas* underscores the Church’s growing influence in shaping discussions around AI’s ethical and societal impact. The document positions the Vatican as a moral authority urging caution, equity, and human-centered design in AI’s future development.
