In a landmark move marking his first major teaching document as pontiff, Pope Leo XIV has published an 82-page encyclical titled *Magnifica Humanitas* (Magnificent Humanity), focused entirely on assessing the growing threats posed by unregulated artificial intelligence development. Dated May 25, 2026, the text, subtitled “On Safeguarding the Human Person in the Time of Artificial Intelligence,” caps years of collaborative theological and ethical reflection within the Catholic Church on advancing digital technology.
The pontiff’s warning builds on earlier institutional efforts to frame ethical guardrails for AI: dating back to 2020, the Holy See partnered with major technology firms and global academic bodies to launch the Rome Appeal for an Ethics of AI, a public initiative calling for AI innovation centered on respect for inherent human dignity. In this new encyclical, Pope Leo XIV expands that framework to detail five pressing risk areas that demand global attention.
First, the encyclical highlights widespread economic and labor disruption, warning that unchecked AI deployment could lead to a rapid contraction of available human employment. The Pope specifically criticizes the dominant business model of big tech, which he says prioritizes short-term profit maximization over the fundamental dignity of work and workers.
Second, the pontiff takes a firm stance against the development of autonomous lethal weapons, commonly referred to as killer robots, including self-operating armed drones. He stresses that any decision to use lethal force must remain under the direct, intentional control of human actors, rejecting the normalization of automated warfare.
Third, Pope Leo XIV addresses the unique risks posed by generative AI, warning that its ability to mimic human interaction, emotion, and identity risks eroding the line between authentic human connection and digital simulation. He reminds readers that every human person’s individuality—marked by their unique face and voice—is inherently sacred, a status that unregulated generative AI threatens to trivialize.
Fourth, the encyclical calls out the heavy environmental toll of the AI boom, denouncing the ecological destruction caused by the unregulated scramble to extract rare earth elements and critical minerals required to power AI infrastructure and modern electronics.
Finally, the document emphasizes that children and young people are uniquely vulnerable to harm from unregulated AI, citing elevated risks of online manipulation, exposure to violent content, and digital exploitation. To counter these threats, the Vatican pushes for widespread investment in accessible digital literacy education, designed to help young people build the critical thinking skills needed to navigate digital spaces safely.
