In a significant intersection of theological tradition and frontier technology, Vatican City served as the backdrop for the release of Pope Leo XIV’s landmark encyclical, Magnifica Humanitas, on December 22, 2025. The event, attended by high-ranking clergy, diplomats, and tech executives, notably featured Chris Olah, co-founder of the artificial intelligence firm Anthropic. The gathering occurs at a volatile moment for the AI industry, as the United States enters a new political era under the "Trump 2.0" administration, which has recently criticized Anthropic for its refusal to waive ethical "redlines" regarding the military application of its technology.
The presence of Anthropic, a firm currently valued in the tens of billions and reportedly eyeing a multi-trillion-dollar initial public offering (IPO), signaled a strategic attempt by the industry to align itself with moral authorities. While the Pope’s encyclical offers a stinging critique of the "AI arms race," Olah used the platform to position Anthropic as a company deeply concerned with the "mysterious" and "unsettling" nature of the systems they have created.
The Encyclical: A Theological Critique of Technological Omnipotence
Magnifica Humanitas represents the most comprehensive Catholic teaching on digital ethics since the dawn of the internet. Drawing heavily on the biblical metaphor of the Tower of Babel, Pope Leo XIV warns against the "temptation of technological omnipotence." The document posits that the current trajectory of AI development risks reducing the human person to a mere "data profile," stripped of the dignity inherent in being a "free subject."
The Pope’s call for "discernment" emphasizes that the rapid advancement of generative models and autonomous systems must not bypass democratic mediation. The encyclical advocates for a "Jerusalem" model of development—one defined by limits, the common good, and the protection of the vulnerable—rather than the "Babel" model of centralized, unaccountable power.
Anthropic’s Testimony: The "Mystery" of Machine Intelligence
Addressing the delegates, Chris Olah provided a rare glimpse into the internal philosophy of Anthropic, a company founded on the principle of "Constitutional AI." Olah moved away from the traditional view of AI as a deterministic tool, instead describing the models as entities that mirror human complexity in ways that remain opaque even to their creators.
"They are not the cold, calculating robots we were promised," Olah stated. "They are made from us, from our words—and, as the Holy Father observes, they remain in important ways mysterious even to those of us who train them."
Olah compared the process of training large language models (LLMs) to "bringing a fictional character to life," noting that the industry is entering a world where these characters perform labor and interact as social agents. He further revealed that research teams studying the internal structures of these models have discovered "internal states that functionally mirror joy, satisfaction, fear, grief, and unease." This admission of "functional introspection" in AI models adds a new layer to the debate over machine sentience and the ethical obligations of those who develop them.
Chronology of the 2025 AI Governance Crisis
The Vatican meeting follows a series of escalating tensions between Silicon Valley and global regulators:
- January 2025: The European Union’s AI Act enters its final phase of implementation, creating a rift between EU regulators and US-based firms.
- March 2025: Anthropic publicly refuses to provide the US Department of Defense with unrestricted access to its Claude models, citing "safety and ethical guardrails."
- June 2025: The Trump 2.0 administration condemns Anthropic’s "left-wing ethical redlines," suggesting that such restrictions hinder national security.
- November 2025: David Sacks, a key AI policy advisor to the Trump administration, successfully lobbies to kill a major AI Executive Order, favoring a deregulated approach.
- December 2025: Pope Leo XIV publishes Magnifica Humanitas, inviting Anthropic to the Vatican for the unveiling.
Economic Implications and the Global Divide
One of the central themes of the Vatican gathering was the potential for AI to exacerbate global inequality. Olah highlighted three critical areas where the Church’s influence is deemed necessary: labor displacement, the concentration of wealth, and human flourishing.
Economic data supports these concerns. Recent projections from the International Monetary Fund (IMF) suggest that AI could impact up to 40% of global employment, with advanced economies seeing more immediate disruption. Olah warned that because AI development is concentrated in a handful of wealthy nations, there is currently no mechanism to ensure the gains are shared globally. "It is an unsolved problem," Olah remarked, "and it is the kind of problem the Church has historically refused to let the world ignore."
Ethical Rebuttal: The Charge of "Vatican Washing"
The alliance between the Holy See and Anthropic was not without its detractors. Timnit Gebru, founder of the Distributed AI Research Institute (DAIR) and a prominent critic of the industry, labeled the event "Vatican washing." Gebru argued that the Vatican’s endorsement allows AI firms to bypass accountability for more immediate harms, such as data theft, labor exploitation in the Global South, and environmental degradation.
"The Vatican could have partnered with the exploited data workers fighting for their rights, the people whose water is polluted fighting data centers, or the many other victims around the world," Gebru stated. She also pointed to the Vatican’s own venture capital interests, suggesting a potential conflict of interest in its promotion of Silicon Valley leaders.
Critics in this camp argue that the "existential risk" and "mystery" narratives promoted by Olah serve to distract from the material costs of AI. According to data from the International Energy Agency (IEA), the electricity consumption of data centers could double by 2026, reaching levels equivalent to the entire energy demand of Germany.
Transatlantic Political Fallout
The political reaction to the encyclical highlighted a deep divide between European and American leadership. Thierry Breton, the former European Commissioner for Internal Market and a primary architect of the EU Digital Services Act, praised the Pope’s message. Breton, who was recently sanctioned by US Secretary of State Marco Rubio and banned from entering the United States, viewed the encyclical as a "blessing" for those fighting to prevent the digital space from becoming a "legal no man’s land."
Breton specifically targeted the "Trumpified Silicon Valley," including JD Vance and Peter Thiel, accusing them of pursuing a "post-political world" governed by private infrastructure without democratic oversight.
Conversely, the response from Washington was mixed. Interior Secretary Doug Burgum dismissed the Pope’s intervention as "editorializing." However, Vice President JD Vance, a Catholic convert, offered a more diplomatic assessment. Vance suggested that the Church’s moral leadership is essential in the "AI age," though he emphasized that the application of moral principles must adapt to a changing world—a nod to the administration’s preference for American dominance in the sector.
Historical Parallels: Rerum Novarum for the Digital Age
Analysts have drawn parallels between Magnifica Humanitas and Pope Leo XIII’s 1891 encyclical, Rerum Novarum, which addressed the "condition of labor" during the Industrial Revolution. Just as Leo XIII sought to protect workers from the excesses of unbridled capitalism, Leo XIV seeks to protect the "human spirit" from the excesses of autonomous technology.
However, historians note a key difference: Leo XIII wrote at a time when the effects of industrialization were already established and visible. Leo XIV is intervening at the inception of the AI revolution, addressing risks that are still largely theoretical. This proactive stance reflects a desire by the Church to shape the "moral imagination" of developers before the technology becomes too entrenched to regulate.
The Path Forward for AI Alignment
The Vatican summit concluded without a formal policy agreement, but it has reframed the debate over "AI alignment." While the tech industry typically defines alignment as ensuring AI follows human instructions, the Pope’s encyclical defines it as ensuring AI serves human dignity.
As Anthropic moves toward its anticipated IPO, the company’s alignment with the Vatican may serve as a buffer against domestic political pressure. For the Vatican, the partnership provides a direct line of influence into the laboratories where the future is being built. Yet, as David Sacks noted, the "oldest questions of human nature and authority" remain. The central question posed by the gathering remains unanswered: "Quis custodiet ipsos custodes?"—Who will guard the guardians of the machines?
In the words of Pope Leo XIV, the "pressing duty" of the modern era is to "remain profoundly human" in the face of new forms of dehumanization. Whether the "moral leadership" of the Church can hold sway over the trillion-dollar momentum of Silicon Valley remains the defining uncertainty of 2026.
