Pope Leo XIV told priests in the Diocese of Rome to resist what he called "the temptation to prepare homilies with Artificial Intelligence." The warning, delivered during a February 19 meeting with local clergy, began circulating widely online this week and landed squarely in a culture already wrestling with what AI should and shouldn't replace.

The pope's reasoning was blunt and physical. He compared the human mind to a muscle that atrophies without use.

"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."

It's a striking image from the head of the Catholic Church, and one that carries weight well beyond the pulpit. In a world racing to automate everything from legal briefs to kindergarten lesson plans, the pope is making an argument that conservatives have been articulating for years: some things lose their meaning the moment you outsource them.

A Sermon Is Not a Spreadsheet

There is a difference between using AI to optimize a supply chain and using it to speak to the souls of a congregation. A homily isn't a product. It's an act of faith, delivered by a person who has wrestled with the text, who knows the people sitting in the pews, who brings the weight of his own vocation to the words he speaks. Breitbart reported.

Hand that task to a large language model and you get something that sounds right. Polished. Coherent. And completely hollow.

Pope Leo XIV seems to understand this instinctively. According to Vatican News, the pope told the assembled priests:

"It is not you: If we are not transmitting the message of Jesus Christ, perhaps we are mistaken, and we must reflect very carefully and humbly about who we are and what we are doing."

That line cuts deeper than any policy paper on AI governance. If the message isn't yours, it isn't ministry. Its performance.

TikTok, Isolation, and the Digital Retreat

The pope didn't stop at AI. He also named the Chinese social media application TikTok as a threat to the work of clergy, pointing to the growing isolation of young people who live increasingly through screens. His description of that isolation was pointed:

"They live a kind of distance from others, a coldness, without knowing the richness, the value of truly human relationships."

His prescription was decidedly old-fashioned. Go to them. Be present. Offer culture and sports. Walk the streets with them.

"We must go ourselves, we must invite other young people, go out into the streets with them; perhaps offer different ways."

None of this requires a wifi connection. That's the point. The pope is telling his priests that the answer to a generation drowning in digital noise is not more digital noise. It's physical presence, human contact, the irreplaceable act of showing up.

Conservatives who have spent years warning about the effects of social media on children and young adults will find a natural ally in these remarks. The erosion of community, the collapse of attention spans, the replacement of real relationships with algorithmic feeds: these are not partisan concerns, but the right has been far more willing to name them plainly.

Leo XIV and the AI Question

This isn't the first time Pope Leo XIV has addressed artificial intelligence. He has made the topic a recurring theme of his pontificate since taking over for the late Pope Francis last year.

When he became the Archbishop of Rome in May 2025, he explained his choice of papal name by pointing directly to his predecessor Pope Leo XIII, best known for leading the Catholic Church during the Industrial Revolution and issuing the encyclical Rerum Novarum.

"I chose to take the name Leo XIV. There are different reasons for this, but mainly because Pope Leo XIII in his historic Encyclical Rerum Novarum addressed the social question in the context of the first great industrial revolution."

He then drew the parallel to the present:

"In our own day, the Church offers to everyone the treasury of her social teaching in response to another industrial revolution and to developments in the field of artificial intelligence that pose new challenges for the defense of human dignity, justice, and labor."

The framing is deliberate. Leo XIII confronted the upheaval of industrialization. Leo XIV intends to confront the upheaval of automation and machine intelligence. Whether you're Catholic or not, the ambition is worth noting.

Acknowledging AI's Promise Without Surrendering to It

To his credit, the pope hasn't taken a Luddite position. At a conference on AI and ethics in June 2025, he acknowledged that the technology has genuine value:

"AI, especially Generative AI, has opened new horizons on many different levels, including enhancing research in healthcare and scientific discovery."

But he immediately followed with the caveat that matters:

"...but also raises troubling questions on its possible repercussions on humanity's openness to truth and beauty, on our distinctive ability to grasp and process reality. Acknowledging and respecting what is uniquely characteristic of the human person is essential to the discussion of any adequate ethical framework for the governance of AI."

That balance is important. The question was never whether AI can be useful. It's whether we can preserve what makes us human while using it. The pope has drawn a clear line: access to data is not intelligence. Processing power is not wisdom. And a machine-generated homily is not ministry.

He reinforced that distinction by referencing the late Pope Francis's January 2025 statement on the relationship between artificial intelligence and human intelligence, noting that data access "must not be confused with intelligence, which necessarily 'involves the person's openness to the ultimate questions of life and reflects an orientation toward the True and the Good.'"

Human Dignity in the Age of the Algorithm

In a message marking the World Day of Social Communications, Pope Leo XIV addressed the use of AI-generated likenesses and voices, grounding his concern in theology:

"Preserving human faces and voices, therefore, means preserving this mark, this indelible reflection of God's love."

He continued:

"We are not a species composed of predefined biochemical formulas. Each of us possesses an irreplaceable and inimitable vocation, that originates from our own lived experience and becomes manifest through interaction with others."

This is the argument the AI debate desperately needs. Not "will it take our jobs," though that matters. Not "is the output good enough," though often it isn't. The deeper question is whether we are willing to defend the idea that human beings possess something a machine cannot replicate, simulate, or replace.

The pope has called for broad collaboration on AI governance, insisting that no single sector can manage the challenge alone:

"All stakeholders — from the tech industry to legislators, from creative companies to academia, from artists to journalists and educators — must be involved in building and implementing informed and responsible digital citizenship."

That's a reasonable framework. But the most powerful thing Pope Leo XIV has done isn't call for regulation. It's telling a room full of priests to put the laptop away, pick up a pen, and think.

In an age that measures everything by efficiency, that's a radical act.
