Spiritual Quote of the Day (Pope Leo XIV, on ‘Standards for Discernment’ in Evaluating AI)

“We cannot condone naive enthusiasms, nor fuel unfounded fears. Instead, let us establish standards for discernment — the dignity of the human person, the universal destination of goods, the preferential option for the poor, care for our common home and peace — and let us translate these standards into practices.”—Pope Leo XIV, Magnifica Humanitas (“Magnificent Humanity”), https://www.vatican.va/, released May 15, 2026

In my post two weeks ago on Pope Leo’s apology for the Church’s stand on slavery over the centuries, I promised to discuss his much-anticipated encyclical, or formal papal pastoral letter, on artificial intelligence. That time has arrived.

When you consider the upcoming stakes for AI (one analyst I heard this past said it had greater potential to affect humanity than space exploration), there has been precious little time devoted to how to ensure it serves rather than degrades humanity.

By reminding tech lords, legislators, and ordinary citizens of that basic principle, Leo’s examination of this new force in our lives can potentially kick-start and even frame the debates that should be taking place now in the public square.

Fully cognizant of AI’s potential benefits, Leo is anything but a technological Cassandra. (Though predictably, the Murdoch-owned Wall Street Journal has turned up its nose at the pope’s urging to install brakes on the runaway technology, with op-ed contributor Louise Perry snidely asking, “Does the Pope Use Air Conditioning”?)

At the other end of the political spectrum, some have written that Leo has not gone far enough in denouncing the ills now becoming apparent in AI.

But his caution only enhances his case that this new technology cannot develop without safeguards that rest on human morality, and in particular on the Catholic Church’s notions on the market economy, technology, and social justice dating back to the groundbreaking encyclical of his predecessor and namesake Pope Leo XIII, Rerum Novarum (1891).

Leo XIV has called for measures ensure the dignity of work in the face of AI, including regulating private companies’ AI development and retraining workers whose jobs are threatened. He has also advocated for critical thinking education about the technology.

It’s not just the danger to livelihoods that concerns the Vatican, however, but also AI’s potential misuse for modern warfare:

“The growing ease with which autonomous weapons systems can be deployed makes war more ‘feasible’ and less subject to human control. This violates the principle that armed force should be used only as a last resort in cases of legitimate self-defense. For this reason, the development and use of AI in warfare must be subject to the most rigorous ethical constraints, to guarantee respect for human dignity and the sanctity of life and to avoid a race to develop such arms.”

In addition, the encyclical raises the alarm about transhumanism, or enhancing human beings through technologies, and posthumanism, which, imagines “a hybrid of human beings, machines and the environment.”

The ultimate impact of these two forces, according to the encyclical, could be to make it “easier to accept that some lives are less useful, less desirable or less worthy…placing the burden on the most vulnerable in pursuit of a supposed optimization of the species.”

As Fordham Univ. papal expert David Gibson’s op-ed last month in The New York Times observed, Magnifica Humanitas has arrived at a “propitious moment,” when “The disruptions of the post-liberal world and the threats posed by A.I. have led many cultural conservatives to make economic justice a priority.”

Even President Trump, who early in his second term likened placing limits on high tech to restricting the growth of a baby, felt compelled to sign an executive order early this month calling for AI companies to voluntarily provide the federal government access to “covered frontier models” for a cybersecurity review up to 30 days before their planned release to “other trusted partners.” It came amid sudden alarm that some powerful AI models autonomously identify and exploit hidden vulnerabilities in real-world software.

It will be up to the tech barons whether they will enter into dialogue with the pope and other advocates for a more deliberate, regulated AI pace or if they will continue to proceed with no guardrails. But Leo has spelled out the moral stakes in no uncertain terms.
