Opinion | Pope Leo’s AI Manifesto
Pope Leo XIV published Magnifica Humanitas, his first major encyclical on artificial intelligence, positioning AI as a moral and social question rather than a technical one. The document argues that AI systems must remain subordinate to human dignity, work, freedom, and responsibility, and warns that current deployments risk eroding human agency, intensifying surveillance, and concentrating power. The encyclical addresses Catholics, governments, developers, employers, and institutions shaping AI policy, and assigns responsibility across the entire AI lifecycle—from designers and developers to those who deploy systems for consequential decisions. The Vatican calls for Catholic social-doctrine principles including subsidiarity, solidarity, justice, and the common good to guide AI governance.
