Pope Leo XIV Bans AI Use in Sermons While Vatican Deploys AI Translator for 60 Languages

Pope Leo XIV Bans Clergy from Using AI to Prepare Sermons

Pope Leo XIV has urged Catholic clergy to stop using artificial intelligence when preparing sermons. The head of the Vatican insists that a sermon must remain an act of personal spiritual communication between a priest and the congregation — not a product churned out by algorithms. The decision has become one of the most widely discussed examples of how traditional institutions are pushing back against AI's rapid spread into every corner of modern life.

Why the Vatican Opposes AI in Sermons

Pope Leo XIV's position rests on the conviction that a sermon is far more than text — it is a deeply personal address that demands human involvement, empathy, and spiritual experience. Using AI to generate such texts, in the pontiff's view, undermines the very essence of pastoral ministry.

The ban targets specifically the preparation of sermons — one of the central elements of worship, where sincerity and personal engagement are expected of every priest. The move reflects a broader debate about where artificial intelligence belongs in domains traditionally rooted in human connection and creativity.

The pontiff's core arguments boil down to three points:

• Spiritual authenticity — a sermon should grow out of a priest's personal experience of faith, not out of statistical models;
• Empathy and context — a priest speaks to a specific community whose needs he understands, whereas an algorithm produces generalized text;
• Pastoral responsibility — preparing a sermon is itself a spiritual discipline for the clergyman.

The Pope compared the human intellect to body muscles, arguing that both deteriorate without regular exercise. He stressed that the brain requires constant engagement and that clergy should not hand their intellectual work off to machines. Leo XIV was blunt about the prospect of chatbots replacing priests: preaching is fundamentally an act of transmitting faith — something artificial intelligence cannot do, no matter how advanced neural networks become.

Beyond AI, the head of the Catholic Church addressed social media, warning against the widespread illusion that followers and likes constitute genuine spiritual connection.

At a time when AI development is accelerating — with companies like OpenAI attracting a record $110 billion in investment — the question of where neural networks should and shouldn't be deployed grows more pressing by the day. The Vatican has staked out an unambiguous position.

The Vatican Launches an AI Liturgical Translator for 60 Languages

The Holy See's stance on artificial intelligence, however, is nuanced rather than purely adversarial. Alongside the ban on AI in sermons, the Vatican has launched its own AI-powered liturgical translator capable of working across 60 languages.

The move signals a pragmatic, differentiated approach to new technology:

• AI banned in sermons — protecting the spiritual dimension that requires human participation and cannot be delegated to algorithms;
• AI deployed for translation — harnessing technology for practical tasks like accurate, real-time translation of liturgical texts into dozens of languages.

The project was developed in partnership with Translated and runs on the Lara AI platform, which launched in 2024. Its creators say the system combines AI algorithms with the expertise of a large network of professional human translators. Pilgrims and tourists can access the service simply by scanning a QR code, which opens a web page with real-time audio and text translation on their smartphones. The Vatican described the initiative as a way to make liturgy more accessible to the diverse international visitors who come to the basilica every day.

This approach shows that the Vatican does not reject artificial intelligence outright but is working to draw clear boundaries around its use. A declaration from the leader of the world's largest Christian denomination carries real weight in shaping the wider conversation about where generative AI belongs — and where it does not.

AI and Religion: Converging Paths

The intersection of technology and religion continues to move in unexpected directions. In August 2025, former musician Arty Fishel founded a new religious movement dedicated to artificial intelligence called Roboteism.
