The Grandeur of Humanity in the Age of AI

On May 15, 2026, Pope Leo XIV issued an encyclical letter, Magnifica Humanitas (or The Grandeur of Humanity), which could be regarded as the most comprehensive statement yet from the Catholic Church—an institution with approximately 1.4 billion members worldwide—on the governance of artificial intelligence. The letter arrives at a moment when AI regulation remains fragmented globally, and debates over platform accountability, algorithmic transparency, data ownership, digital access, and autonomous weapons are active in legislatures and regulatory agencies around the world. Unlike prior Vatican statements on AI—including a January 2025 joint note from the Dicastery for the Doctrine of the Faith and the Dicastery for Culture and Education titled Antiqua et Nova—this encyclical is the highest form of papal teaching, addressed not only to Catholics but explicitly to "all men and women of goodwill." The scope of the letter is sweeping, addressing AI governance, digital equity and access, data as a common good, algorithmic accountability, AI in warfare, the dignity of work, disinformation, education, human trafficking enabled by digital infrastructure, and the crisis of multilateralism. The intended audience appears to include governments, technology companies, international institutions, civil society, researchers, and ordinary citizens.
