Pope Leo targets artificial intelligence

Pope Leo XIV is moving to make artificial intelligence an early test case for his papacy, with Axios reporting on May 14 that he is preparing an encyclical centered on AI, labor and human dignity. The Vatican has not yet published such a document on its official site, but Leo’s public remarks this week have put AI alongside war, peace and the protection of vulnerable people. In a May 14 visit to Rome’s Sapienza University, he warned about the dangers of artificial intelligence in warfare and urged students to become “artisans of true peace.” In a separate message for the Turin International Book Fair, he said literature should become “a school of fraternity and peace.” ### What exactly is Pope Leo said to be preparing? Axios reported on May 14 that Leo is expected to sign his first encyclical as soon as Friday and that the text would frame artificial intelligence as a moral and labor question rather than only a technical or commercial one. Axios said the document is reportedly titled “Magnifica Humanitas,” though that title has not been confirmed in any Vatican publication visible in current official sources. (axios.com) An encyclical is one of the Catholic Church’s highest-ranking forms of papal teaching, and a first encyclical typically signals priorities for a new pontificate. Axios said Leo’s text would argue that technology must remain subordinate to the human person and protect workers and moral agency. ### What has Leo said in public about AI so far? Pope Leo XIV used a May 14 address at Sapienza University to connect AI to war and peace. (axios.com) Vatican News said he warned against rising military spending and “the dangers of artificial intelligence in war” while urging young people to reject resignation and become “artisans of true peace.” The Associated Press reported on May 15 that Leo also denounced investment in AI-directed weaponry, saying it risks a “spiral of annihilation.” AP described the remarks as part of a broader warning about high-tech warfare. ### Why are literature and universities showing up in this story? Vatican News reported on May 14 that Leo sent a message to the Turin International Book Fair saying literature should help people recognize “the dignity of every person, especially the most vulnerable,” and become “a school of fraternity and peace.” The fair runs from May 14 to May 18 in Turin, according to Vatican News. (vaticannews.va) (apnews.com) Sapienza University provided another stage for the same vocabulary. Vatican News said Leo’s visit on May 14 included an appeal to students to resist indifference and work for peace, with AI mentioned in the context of warfare rather than productivity or consumer technology. Vatican News had previewed the visit on May 12, saying Leo would arrive at 10:20 a.m. for prayer, greetings and a speech in the Aula Magna.

A June 17, 2025 papal message to a Rome conference on AI, ethics and corporate governance said Leo was addressing questions about the common good, while a November 7, 2025 message to a congress on AI and medicine described “human dignity” as the central challenge. In a December 5, 2025 address, Leo asked how AI could serve the common good rather than concentrate wealth and power “in the hands of a few.” (vaticannews.va) Those earlier messages do not confirm the contents of a coming encyclical, but they show that AI has already become a recurring subject in Leo’s official communications. Vatican sources have tied the technology to children, medicine, corporate governance and the common good, not only to innovation policy. ### What should readers watch for next? (vatican.va) Friday, May 15 is the first date to watch because Axios said Leo could sign the encyclical as soon as that day. The next concrete confirmation would be publication on the Vatican’s official website or a formal announcement through Vatican News or the Holy See Press Office. Until then, the clearest on-record evidence remains Leo’s May 14 speeches and messages linking AI to peace, dignity and the protection of vulnerable people. (vatican.va) (axios.com)
