Pope Leo XIV has urged Catholic priests to steer clear of using artificial intelligence tools such as ChatGPT to write their sermons, arguing that no algorithm can substitute for lived faith, personal prayer, and real experience.

AI in the Pulpit? Pope Says That’s a Problem

Speaking to clergy from the Diocese of Rome, the Pope addressed the growing presence of technology in everyday ministry. While he acknowledged its expanding role, he drew a clear line at outsourcing homilies to machines.

According to Vatican reports, Pope Leo XIV described the use of AI to craft sermons as a kind of “temptation” for priests. Relying on chatbots and similar tools, he warned, could dull a priest’s intellectual and spiritual habits over time.

He framed it in physical terms: just as muscles weaken without use, the mind and its capacity for reflection can atrophy if they’re not actively engaged.

“AI Will Never Be Able to Share Faith”

The Pope’s main concern isn’t just about plagiarism or presentation, but about authenticity. For him, a homily isn’t a speech that needs good structure and smooth delivery; it’s an act of sharing personal belief.

“Like all the muscles in the body, if we do not use them, if we do not move them, they die. The brain needs to be used, so our intelligence must also be exercised a little so as not to lose this capacity,” he told the gathered priests.

He added that “to give a true homily is to share faith,” insisting that artificial intelligence, no matter how sophisticated, “will never be able to share faith.” The implication is clear: a generated text might sound polished, but it lacks the interior life and conviction that should sit behind preaching.

Local Communities Want Real Experiences, Not Generic Text

Pope Leo XIV also highlighted the importance of context and community in preaching. A homily, he suggested, should be rooted in the specific place and people a priest serves, not in a generic template created by a machine trained on global data.

“If we can offer a service that is inculturated in the place, in the parish where we are working, people want to see your faith, your experience of having known and loved Jesus Christ,” he said.

That idea of being “inculturated” — shaped by the culture and reality of a specific parish — runs directly against the one-size-fits-many nature of AI writing tools. The Pope’s message to clergy was that their communities are looking for the priest’s own journey and witness, not a synthetic summary of theology.

Part of a Bigger Warning on Tech and Relationships

These comments fit into a larger pattern in Pope Leo XIV’s public statements about new technology. He has repeatedly raised concerns about the impact of rapidly evolving AI on ordinary human relationships.

In earlier remarks, he pointed to AI chatbots and virtual influencers as potential threats to real-world connections if people start treating digital personas as replacements for actual human interaction. This latest warning about AI-written sermons carries a similar concern into the spiritual sphere: that digital tools might edge out the messy, time-consuming, but essential work of personal encounter and reflection.

The Pope’s stance doesn’t dismiss technology outright, but it draws a firm boundary when it comes to core pastoral duties. Homilies, in his view, belong on the human side of that line — crafted through study, prayer, and lived experience rather than generated by software.

What This Means for Priests Using AI

For clergy already experimenting with AI to draft ideas, outlines, or examples, the Pope’s language about “temptation” reads like a direct caution. The practical tradeoff he’s highlighting is simple:

  • Short-term gain: AI can quickly produce structured, theologically tidy text.
  • Long-term loss: Over-reliance could weaken a priest’s own habits of study, prayerful reflection, and personal engagement with Scripture.

In other words, saving time now might come at the cost of spiritual and intellectual formation over the years. For Pope Leo XIV, that’s too high a price — especially when the task at hand is preaching, which he defines as a direct sharing of one’s own faith rather than a polished religious essay.

As AI tools become more capable and more common, the Pope is clearly signaling where he thinks the Church should stand: use technology where it serves people, but don’t let it take over the deeply human work of speaking heart-to-heart about belief.
