Pope Leo XIV unveils AI encyclical

Pope Leo XIV will present his first encyclical on May 25 at the Vatican, putting artificial intelligence at the center of his first major teaching document as pope. The text, titled *Magnifica Humanitas*, is described by the Holy See Press Office as an encyclical on safeguarding the human person in the time of artificial intelligence. (press.vatican.va) The Vatican said the document carries Leo’s signature dated May 15, the 135th anniversary of Pope Leo XIII’s *Rerum Novarum*. National Catholic Reporter said Leo will appear alongside Anthropic co-founder Dario Amodei at the presentation. ### Why is this document getting unusual attention before it is even published? (press.vatican.va) The May 25 presentation is unusual because the Vatican said Leo himself will attend the event in the Synod Hall, rather than leaving the rollout entirely to curial officials. The Holy See Press Office listed speakers including Cardinal José Tolentino de Mendonça, Archbishop Vincenzo Paglia, legal scholar Marta Cartabia and Anthropic co-founder Dario Amodei. National Catholic Reporter said the pairing with Amodei underscores the Vatican’s effort to engage directly with companies building advanced AI systems. The outlet reported that Leo’s encyclical is his first major teaching document and said the event links the church’s moral teaching to a live policy and industry debate over how AI should be governed. (press.vatican.va) ### What has the Vatican actually said the encyclical is about? The Holy See Press Office said *Magnifica Humanitas* is “on Safeguarding the Human Person in the time of Artificial Intelligence.” Digital Watch reported that the Vatican described the text as examining AI through the lens of Catholic social teaching and technological change, with a focus on protecting human dignity. (press.vatican.va) America Magazine reported that the encyclical is being introduced as Leo’s first encyclical and tied it to a broader Vatican push to address AI as a moral and social question, not only a technical one. In a separate report, the magazine said Leo signed the document on May 15 and noted the date’s connection to *Rerum Novarum*, the 1891 encyclical that became a foundation of modern Catholic social teaching. (ncronline.org) ### Why does the May 15 date matter? The Vatican said the document is dated May 15 to mark the 135th anniversary of *Rerum Novarum*, Pope Leo XIII’s encyclical on labor and capital. That reference places Leo XIV’s AI text in a line of church documents that respond to major economic and social upheaval. (press.vatican.va) America Magazine reported that church observers see the choice as deliberate because *Rerum Novarum* addressed the dislocations of industrial capitalism, while the new encyclical addresses the effects of digital and machine-driven change. That comparison is the publication’s characterization, but it is grounded in the Vatican’s own decision to date the document to the earlier encyclical’s anniversary. (americamagazine.org) ### How does this fit with Leo’s other moves on artificial intelligence? On May 16, America Magazine reported that Leo approved an inter-dicasterial Vatican commission on artificial intelligence. National Catholic Reporter also reported on May 16 that the pope created an AI study group as the Vatican prepared the encyclical’s release. (press.vatican.va) Digital Watch has separately tracked Vatican AI guidance issued earlier in 2025, describing it as an effort to set ethical guardrails for the technology. Those steps suggest the encyclical is arriving as part of a broader institutional campaign, though the full substance of Leo’s own text will not be known until publication. (americamagazine.org) ### What happens on May 25? The Holy See Press Office said the presentation will begin at 11:30 a.m. in the Synod Hall on May 25, 2026, in the presence of Pope Leo XIV. The listed speakers are Cardinal Tolentino de Mendonça, Archbishop Paglia, Cartabia and Amodei. (americamagazine.org) The next concrete milestone is the publication of *Magnifica Humanitas* itself on May 25, when the Vatican is expected to release the full text and the speakers are scheduled to discuss it publicly in Rome.
