Although Vatican City has never traditionally been viewed as a center for regulating technology, the release of Magnifica Humanitas, the new encyclical by Pope Leo XIV, is not something the AI industry can casually dismiss.
Far from being a purely theological reflection, the document addresses some of the most urgent questions surrounding artificial intelligence governance with remarkable clarity and moral weight.
Pope Leo XIV does not advocate banning AI altogether. Instead, he argues that artificial intelligence must be restrained, governed responsibly, and developed within ethical boundaries — a distinction that matters deeply. His concern is not rooted in hostility toward innovation or scientific progress, but in the concentration of power surrounding AI development.
According to the encyclical, the private ownership of massive datasets, the relentless race among corporations driven by profit, and the social costs imposed on workers and children to sustain enormous computing systems represent failures of governance rather than failures of technology itself. These are precisely the areas where regulators around the world have struggled to act decisively.
Leo’s appeal for politics to “slow things down when everything is accelerating” may sound unrealistic within the culture of speed that defines Silicon Valley. However, the argument is not against innovation itself. It is a warning against surrendering democratic oversight to private transnational corporations whose influence and resources increasingly rival those of nation-states.
That concern is no longer hypothetical — it reflects the reality of today’s technological landscape.
The Machines of War
Perhaps the most urgent — and least discussed — section of the encyclical focuses on autonomous weapons systems.
According to Pope Leo XIV, AI systems must never be entrusted with the authority to decide when a human life should end. He argues that lethal autonomous weapons strip war of its remaining moral accountability. In doing so, they do not merely change warfare — they risk creating a world where peace itself becomes harder to sustain.
Machines capable of selecting and eliminating targets without direct human judgment represent a profound break from the ethical foundations that have historically governed armed conflict.
The issue itself is not new. Organizations such as the International Committee of the Red Cross (ICRC) and a growing coalition of nations have debated the dangers of autonomous weapons for years. What Pope Leo XIV adds to the discussion is moral authority on a global scale.
The Catholic Church speaks to more than 1.4 billion people worldwide. When the Pope declares that delegating the decision to kill to machines violates human dignity, the message resonates far beyond theology — reaching governments, military institutions, defense contractors, and ordinary citizens alike.
Leo also highlights a connection often overlooked in mainstream AI governance debates: many of the same corporations leading civilian AI development are simultaneously competing for military contracts. The “disarmament” he advocates is therefore not symbolic rhetoric. It is a direct challenge to humanity’s willingness to outsource life-and-death decisions to systems optimized primarily for efficiency and performance.
One of the most important questions raised in the encyclical is profoundly simple: if humanity feels uncomfortable allowing machines to determine who lives and who dies, do we still possess the political courage to stop such systems before they become irreversible?
At the current moment, the answer remains uncertain. But in an age increasingly shaped by artificial intelligence, the encyclical succeeds in doing something rare — it forces the world to pause and confront the ethical consequences of technological progress before it moves beyond human control.
