Pope Leo XIV's AI encyclical isn't regulation, it's moral agenda-setting. The real test: can our institutions govern AI before profit and power override ethics?
At an unusual Vatican venue on May 25, in the Synod Hall in Rome, Pope Leo XIV stood next to Anthropic co-founder Chris Olah and presented his papal ethical take on artificial intelligence.
Its title in Latin: Magnifica Humanitas, “Magnificent Humanity.” The vehicle was a 42,000-word papal encyclical on artificial intelligence, one of a long line of such documents dating back to the first encyclical in 1740.
The conversation around AI has focused mostly on capability. Which model is stronger? Which company is ahead? Which lab will reach the next milestone first?
That surface-level debate misses the real constraint.
The deeper question is not only what AI can do. It is what kind of human order AI is being built into. Who decides? Who benefits? Who is displaced? Who is protected? And what happens when tools designed for efficiency begin to reshape work, authority, judgment and responsibility?
Pope Leo’s answer is clear enough. In Magnifica Humanitas, he calls for the ethical disarming of AI, comparing its dangers to nuclear energy. He asks that human dignity be placed before optimization. He calls for the protection of workers’ rights, the protection of children from harmful uses of AI, moral oversight over technology used by the military, and limits on decisions that machines should never be allowed to make alone.
Working, Pope Leo asserts, is a requirement of the human condition. A world where AI does most of the work may be efficient. But efficiency is not the same as human flourishing.
It is tempting to treat papal documents cynically. Near the end of World War II, Winston Churchill reportedly suggested to Josef Stalin that they consult the Pope. Stalin scoffed: “How many divisions does the Pope have?”
The answer, in this case, is not military. It is institutional.
The Catholic Church has roughly 1.4 billion adherents, about one-sixth of humanity. That does not give Pope Leo command over AI labs, cloud providers or national security agencies. It does give him something different: a platform for moral agenda-setting at global scale.
That matters because AI governance is not only a technical problem. It is an institutional problem.
The bottleneck is not awareness. Everyone knows AI is powerful. The bottleneck is coordination. Companies have incentives to move first. Governments have incentives to avoid falling behind. Militaries have incentives to preserve advantage. Consumers have incentives to adopt convenience before they understand the cost. Workers have little ability to negotiate with systems that arrive faster than labor law can adapt.
This is where the Pope’s intervention is useful. Not because the Vatican can regulate AI. It cannot. But because moral language often arrives before policy language. It defines what a society is allowed to ask.
In 1891, another Pope Leo, Leo XIII, published Rerum Novarum, “Of New Things.” It addressed the industrial economy, the rights of workers, the duties of employers and the moral limits of unfettered capitalism. It did not stop industrialization. But it helped frame the social question of the age: how could technological progress be reconciled with human dignity?
The current moment has a similar shape.
AI is often described as the Fourth Industrial Revolution. The phrase is overused, but the comparison is still useful. Industrial revolutions do not simply introduce machines. They reorganize society around new bottlenecks. Steam power reorganized production. Electricity reorganized factories, homes and cities. Computing reorganized information. AI may reorganize judgment.
That is why the ethical question is not an accessory to the technology. It is part of the technology’s operating environment.
A model that writes, ranks, classifies, recommends, diagnoses, surveils or targets is not just a tool. It is a participant in a decision system. Its impact depends on incentives, data, safeguards and the people who remain accountable when something goes wrong.
This is also why “human in the loop” is too easy a phrase. Which human? With what authority? Under what pressure? Facing which incentives? Human oversight can be real. It can also be theater.
Pope Leo’s argument is strongest when read this way. He is not asking whether AI should exist. He is asking what kind of social architecture should surround it.
There is a smaller, almost charming detail in the story. Pope Leo XIV was born and raised in Chicago and is a lifelong fan of the Chicago White Sox. He attended a World Series game in 2005, when Chicago defeated Houston. The White Sox went on to sweep the series, winning their first World Series in 89 years. After that, it was all downhill. In 2024, they lost a record 121 games out of 162. But Pope Leo remains a staunch supporter.
It is a fitting metaphor. Institutions endure by holding commitments through long losing seasons.
Will Magnifica Humanitas ignite debate and policy action? There is reason for hope, but not certainty. The real test will not be rhetoric. It will be governance.
The question is whether AI ethics can survive contact with competition, market pressure, geopolitical rivalry and user demand. It is easy to endorse human dignity in principle. It is harder to protect it when the fastest path to profit is automation, when the fastest path to state power is surveillance, and when the fastest path to consumer adoption is frictionless dependence.
Will Magnificent Humanity become a serious moral framework, or will it become another noble document filed away while the machinery moves on?
Will Pope Leo have to call on St. Jude, one of the twelve apostles and the patron saint of lost causes?
The challenge is not whether AI will become more capable. It will. The challenge is whether our institutions, laws, markets and moral habits can become capable enough to govern it.
