Pope Leo XIV's encyclical 'Magnifica Humanitas' targets AI's war and labor risks

Pope Leo XIV is preparing to release his first major encyclical, 'Magnifica Humanitas' (Magnificent Humanity), on May 25, 2026, making AI the central focus of a papal document for the first time. According to Vatican announcements, the text will raise specific concerns about AI's role in warfare—likely referencing autonomous weapons systems—and its potential to undermine labor protections and workers' dignity. The timing aligns with growing global regulatory efforts, from the EU AI Act to UN discussions, as religious institutions join the conversation about ethical boundaries for rapidly advancing technology.

The encyclical is expected to blend Catholic social teaching with contemporary tech ethics, arguing that AI must serve human flourishing rather than replace human judgment. While the Vatican has issued statements on AI before (e.g., the 2020 Rome Call for AI Ethics), 'Magnifica Humanitas' represents a deeper, formal doctrinal intervention. It may propose principles for military use of AI, call for transparency in algorithms affecting employment, and advocate for inclusive design that protects vulnerable populations. This could influence Catholic-majority nations' AI policies and shape public discourse among 1.3 billion Catholics worldwide.
