Overview
- The Vatican published the encyclical on Monday, May 25, 2026, and Pope Léon XIV presented the text in person at the Vatican with senior Holy See officials and Christopher Olah, cofounder of Anthropic.
- The 130‑page document centers human dignity and argues that regulation alone is not enough, calling instead to 'désarmer' or disarm AI to prevent technologies from dominating people.
- It lists concrete policy aims such as slowing certain AI developments, expanding public control over data and platforms, creating independent oversight bodies, and protecting workers and children from harms tied to automation and exploitation.
- The encyclical condemns environmental and social costs in AI supply chains, warns of 'new forms of slavery' including child labor in rare‑earth extraction, and insists lethal decisions must remain under human control in military uses.
- The text builds on the Vatican’s multi‑year engagement on AI ethics dating to the 2020 'Appel de Rome' and is positioned to be a moral reference in global debates over AI governance, corporate power and social justice.
