Pope Leo releases encyclical calling to disarm AI

May 25, 2026

Pope Leo XIV released his first encyclical on May 25, calling for AI to be disarmed in service of the common good. The 40,000-word document, titled Magnifica Humanitas, was signed on May 15 in Rome.

The pope issued the encyclical with Anthropic co-founder Chris Olah at his side. It updates Catholic social teaching for the age of AI, which Leo describes as the res novae of our time. The text critiques AI-powered autonomous weapons and the hoarding of data and algorithms by tech elites, likening their actions to colonial extraction of health and genetic information from vulnerable regions.
