Pope Leo XIV's AI Encyclical 'Magnifica Humanitas' to Redefine Catholic Stance on Technology and Labor Rights

Pope Leo XIV is expected to sign his first encyclical as early as Friday, May 10, 2025, positioning artificial intelligence as the defining moral and labor challenge of a new industrial revolution.

The document, reportedly titled Magnifica Humanitas (Magnificent Humanity), would become the Catholic Church’s clearest attempt yet to place human dignity, labor rights, and ethics at the center of the AI race.

Key Details of the Encyclical

Catholic and European outlets report that Leo XIV is poised to sign the AI encyclical on the anniversary of Rerum Novarum (May 15, 1891), Pope Leo XIII’s foundational industrial-era labor encyclical.

The encyclical will focus specifically on AI’s impact on people and working conditions, framing it as Leo XIV’s effort to modernize Catholic social teaching for the AI era, according to Le Monde.

Other reports suggest Magnifica Humanitas will argue:

• Technology must remain subordinate to the human person—not the reverse.
• AI systems should protect workers, creativity, and moral agency.

The Vatican has not commented publicly on the encyclical’s contents but has implemented formal AI guidelines and monitoring structures within Vatican City.

Context: AI as a Moral and Labor Challenge

The late Pope Francis repeatedly warned that AI risked reducing humans to data points and accelerating inequality, surveillance, and autonomous warfare. The Holy See also backed the Rome Call for AI Ethics, an initiative urging transparency and human-centered AI development.

Encyclicals: A Blueprint for the Papacy

Encyclicals are among the most important documents a pope issues, used to set priorities and define how the Catholic Church responds to major global challenges. They often act as blueprints for a papacy, signaling what issues will take center stage for the world’s 1.4 billion Catholics.

Vatican’s Growing AI Oversight

The Vatican has stepped up cybersecurity partnerships and AI oversight efforts, blending defense with diplomacy and ethics. In February 2025, Leo XIV told priests not to use AI to write homilies or to seek "likes" on social media platforms like TikTok.

Expert Reactions

"This is exactly the fear … that machines were replacing human labor. And that's exactly what we're seeing right now with AI." — Andrew Chesnut, Chair of Catholic Studies at Virginia Commonwealth University, speaking to Axios

Chesnut added that Leo XIV is treating AI less like a tech trend and more like a replay of the industrial revolution, with entry-level workers already "evaporating" as automation accelerates.

"This is going to be one of the fundamental pillars of his papacy."

Symbolic Naming: A Mission Statement

Leo XIV’s choice of name for the encyclical increasingly appears to be a mission statement. By invoking Leo XIII, the pope is explicitly drawing parallels between 19th-century industrialization and the AI revolution now unfolding, Catholic experts say.

The message: The Church believes it has a historic role to play again during a period of technological upheaval.

Preparations in American Catholic Institutions

Some American Catholic institutions have been preparing for this moment and discussing the ethical implications of AI. For example, the Catholic Health Care Association of the United States (CHA) has been examining AI’s ethical implications as it increasingly shapes healthcare delivery.

The bottom line: The Vatican is signaling it does not intend to sit out the AI era.
