Pope Leo XIV issues first encyclical on AI ethics, partners with Anthropic co-founder on launch

The Vatican just dropped its most consequential technology document in decades. Pope Leo XIV, the first US-born pope, unveiled his inaugural encyclical on May 25, a sweeping moral framework for artificial intelligence that warns the technology could erode human dignity and create modern forms of bondage.

The document, titled Magnifica Humanitas: On Safeguarding the Human Person in the Time of Artificial Intelligence, calls for international regulatory cooperation and positions the Catholic Church as a moral compass for a world racing to deploy AI systems faster than anyone can assess their consequences.

What the encyclical says, and who showed up

Signed on May 15 and formally presented ten days later, Magnifica Humanitas frames AI through the lens of Catholic social teaching. Its core argument: artificial intelligence, left unchecked, risks becoming a tool for exploitation rather than liberation.

The encyclical warns specifically about AI’s capacity to spread misinformation and foster what the pope calls “new forms of slavery.” Pope Leo XIV urged comprehensive regulation and protections designed to ensure AI development serves the common good. The document pushes back against purely profit-driven or military-oriented AI deployment.

The Vatican launch event featured Christopher Olah, co-founder of Anthropic, the AI safety lab behind the Claude family of models. Olah’s presence represents an unusual bridge between one of the world’s oldest institutions and one of its newest technology companies, both of which claim to be centered on safety and human welfare.

Historical echoes and deliberate timing

Magnifica Humanitas was presented exactly 135 years after Pope Leo XIII issued Rerum Novarum, the landmark 1891 encyclical that addressed the rights of workers during the Industrial Revolution. That document reshaped Catholic engagement with economic systems and laid the groundwork for modern Catholic social teaching on labor, capital, and human dignity.

Where Rerum Novarum confronted the human costs of industrialization, Magnifica Humanitas tackles the human costs of automation and algorithmic decision-making.

What this means for crypto and digital assets

The encyclical contains no references to cryptocurrency, blockchain technology, or digital assets of any kind. When one of the world’s most influential moral authorities writes a comprehensive document about technology’s risks to human dignity and doesn’t mention crypto, it indicates where digital assets sit in the hierarchy of institutional concern. The Vatican clearly views AI as the defining technological challenge of this era, not decentralized finance.

The encyclical’s call for comprehensive technology regulation could accelerate broader regulatory momentum globally. Regulatory frameworks built for AI often expand to cover adjacent technologies including digital assets.
