Pope Leo XIV issued his first encyclical on May 26, 2026 [1], warning that artificial intelligence poses significant anti-human risks to society.
The document marks a shift in the Catholic Church's approach to emerging technology by elevating AI ethics to a religious imperative. By calling for the "disarmament" of certain technologies, the Pope is positioning the Vatican as a moral arbiter in the global debate over algorithmic governance.
In the encyclical, titled "Magnifica humanitas" [2], the Pope argues that unchecked AI development threatens to dehumanize the global population. He urged the international community to establish strict ethical guidelines to prevent the technology from undermining human dignity [3]. The text specifically highlights the need to regulate or disarm AI technologies that are deemed anti-human [1].
This is the first major papal document released by Leo XIV since his ascension. The encyclical focuses on the existential dangers posed by algorithms that operate without moral constraints, a concern that has grown as AI integration increases across global industries [4].
The Vatican's call for disarmament suggests that some forms of AI may be fundamentally incompatible with human rights. The Pope said the world must act to ensure that technology serves humanity rather than replacing or diminishing it [5].
Reactions to the document have already begun. Some political figures, including JD Vance, said the warnings in the encyclical were profound [6]. The call for a global framework reflects a growing trend of religious and civic leaders seeking a unified approach to AI safety [3].
The Pope's message emphasizes that the pursuit of technical efficiency must not override the preservation of the human spirit [4]. He called for a collective effort to ensure that AI remains a tool for the common good [5].
“The Pope issued his first encyclical, calling for the global regulation or disarmament of artificial intelligence technologies.”
The issuance of "Magnifica humanitas" signals that the Vatican intends to move beyond general ethical suggestions and toward a demand for concrete, global regulatory frameworks. By using the term "disarmament," the Church is framing the unchecked growth of AI not merely as a technical challenge, but as a security threat to human nature itself. This puts the Vatican in alignment with a growing international movement advocating for a "pause" or strict limitation on high-risk AI development.
