Essential Background

Pope Leo XIV was elected in May 2025, becoming the first American-born pope. He previously served as Cardinal Robert Prevost and has a background in missionary work. Since the beginning of his pontificate, Pope Leo XIV has expressed significant concern about the rise of artificial intelligence and its impact on humanity, viewing it as a challenge comparable to the Industrial Revolution. An encyclical is a papal letter, among the highest forms of papal documents, often addressing matters of doctrine, morality, or social teaching to the Catholic faithful and all people of goodwill. Anthropic is a leading AI safety and research company, known for its focus on ethical AI development and its Claude chatbot. Christopher Olah is a co-founder of Anthropic and leads its interpretability team, focusing on understanding how AI systems work.

The Full Story

On May 25, 2026, Pope Leo XIV released his first encyclical, titled "Magnifica Humanitas" (Magnificent Humanity), which provides comprehensive moral guidance on safeguarding the human person in the age of artificial intelligence. The encyclical, signed on May 15, 2026, the 135th anniversary of Pope Leo XIII's Rerum Novarum, frames AI as a "new industrial revolution" and warns against its potential to amplify inequality, erode democracy, and devalue human capacities. It emphasizes that AI must serve human dignity and the common good, not solely profit or efficiency.

In a notable break from Vatican protocol, the encyclical's presentation at the Vatican included remarks from Christopher Olah, a co-founder of Anthropic. Olah, an atheist tech leader, spoke alongside Pope Leo XIV, advocating for a partnership between the Catholic Church, governments, civil society, and the tech industry to ensure AI development is guided by external ethical oversight. He highlighted concerns about mass job displacement due to AI and the concentration of AI benefits in wealthy nations, arguing for a "moral imperative of historic proportions" to address these issues. The encyclical itself calls for robust legal frameworks, independent oversight, and user education to "disarm AI" from a mentality of "armed competition" and prevent its control from shifting solely to for-profit corporations.

Why It Matters

This encyclical is a landmark document, elevating the ethics of artificial intelligence to a major religious imperative and setting a clear moral tone for Pope Leo XIV's papacy. Its release signifies a critical moment where ancient philosophical and religious principles are directly engaging with cutting-edge technological advancements. The call for external oversight and collaboration between religious institutions, governments, and the tech industry underscores a growing recognition that AI's societal impact is too profound to be managed by the tech sector alone. The document’s focus on human dignity, labor, and social justice provides a framework for evaluating AI's ethical implications, pushing for a more humane and equitable future amidst rapid technological change.
