Live updates: ‘Magnifica humanitas’ aims to address ‘culture of power’ in AI
Expert theologians liveblog Pope Leo's first encyclical
Editor’s note:
Pope Leo XIV on Monday published Magnifica humanitas, an encyclical meant to focus on the dignity of work, and the assurance of social justice amid the extraordinary technological advancements of recent years.
ln addition to The Pillar’s reporting, we have invited several theologians to offer reaction and analysis as they read the text, to help readers unpack Pope Leo’s first encyclical.
This page will be updated May 25 and 26, as those theologians — along with The Pillar’s newsroom — continue their close readings of the document, and offer analytical reflections along the way.

Joe, I get what you are saying, but a claim like “AI’s power remains entirely tied to data processing” isn’t an ontological claim, right? It is a technical/empirical one.
There are lots of other claims in #99 which seem to be more ontological in nature, but some are not.
As you know, there is lots of disagreement about how much of what is happening in the new frontier models can be reduced to data processing.

On Chapter Three: Technology and Dominance
From paragraph #104: “ethical discernment cannot be limited to asking whether we are using a system for good or bad purposes; it must also examine how that system is designed and what vision of the human person and society is embedded in the data and models that guide it.”
This is really important.
It means that we can’t be facile in our technological ethics — we can’t simply ask, “are we using AI for good or ill?”
That’s an important question to address (of course!), and to address through the lens of the Church’s moral teaching.
But our ethical analysis must be more subtle, and include structural dimensions that go beyond questions about ethical usage.

On Chapter Three: Technology and Dominance
Totally agree, Charlie, that these paragraphs are going to get a lot of attention! My current read is this: paragraph #98 is epistemic. It is primarily about our limitations in knowing how AI systems work. Paragraph #99, by contrast, is ontological — it is primarily about the nature of AI.
So we get a fairly clear take in #99, but a more tentative take in #98.
Epistemically, after all, we are on shakier ground when it comes to AI; but ontologically, given the Church’s stance about human intelligence, the importance of embodiment to the human person, etc., we can be much clearer.

On Chapter Three: Technology and Dominance
I love this encyclical SO MUCH. But I do think I’ve come across an interesting and perhaps significant tension in how it understands the technical and empirical realities of AI.
In #98, the encyclical says something quite remarkable and probably surprising to many: namely, that AI systems are more “cultivated” than “built,” that developers “do not directly design every detail, but instead create a framework within which the intelligence grows,” and that “fundamental scientific aspects” of how AI works remain unknown. This is a striking description of the epistemic situation, and it represents exactly the kind of thing the Catholic Church has often done well: keeping its powder dry when it comes to technical matters in which it does not have competence and which are contested/open questions for the technical experts.
But then, in #99, it proceeds to make a series of confident and definitive claims about AI. Stated not as what seems to be the case but as what is categorically true. For instance, the claim is made that its power “remains entirely tied to data processing.” That may or may not be true, but it is in some tension with the claims about the epistemic situation in the previous paragraph. The encyclical in these two paragraphs essentially says something like: Even the best experts don’t really know how these systems work, but here are some confident claims about how these systems work.
Why doesn’t the position of epistemic humility in #98 govern the claims in #99? I feel like these two paragraphs are going to get a lot of attention and will be the subject of much discussion and debate.

From the concluding paragraph of Chapter 1 (paragraph 45): “Considering this historical overview, it is clear that the Church’s Social Doctrine is not the result of a project devised at a desk, but rather the product of a patient process in which each pontiff — together with the Second Vatican Council — made a unique contribution in light of the “new things” of each particular era.”
Both a helpful summary of the development of the Church’s Social Doctrine, and sets the context for this new encyclical. The Holy Father is positioning the encyclical in the tradition, and positioning his thoughts on the ‘new things’ of our era--in particular, AI--in light of this tradition.

This gloss on the Church’s Social Doctrine in paragraph 27 seems like it will be important: “It is not a handbook of principles and norms to be applied, but a process of shared discernment.” I’m guessing this will be an organizing principle for the discussion to follow. We won’t see as many strict principles or norms, but rather guidelines for shared discernment.

his caught my attention from paragraph 12: “building for the common good means accepting the limits and weakness of humanity without considering them an error to be corrected” and later in the same paragraph, “true fulfilment is not achieved by eliminating weakness but through harmonious growth.” The key virtue being extolled here is humility. I find it helpful to contrast the worldly values of continuous growth upheld by transhumanism (and often, the wider culture as well) and the Gospel values articulated so clearly in the Beatitudes. Hold up the Beatitudes and the acceptance of limits and weakness and contrast these with the driving values of so much of our 21st century imagination, and the contrast couldn’t be starker.

Yes, Joe, I was also quite surprised by the image from Nehemiah. It is not an image used commonly in discussions on AI technology in the way the Tower of Babel image is.
The image of from Nehemiah paired with the reference to Revelation also brings out the image of nature or the garden since it is a tree at the center of the Holy City. I find forefronting nature and the natural world in combination with human building to be a striking and important image for technology ethics.
5/25/26, Joe Vukov, 6:29 AM
Thanks Catherine! I appreciated the two biblical images as well: the tower of Babel and rebuilding of the walls of Jerusalem. The tower of Babel is an obvious and appropriate image, and I very much like this from paragraph 10: “We must, then, avoid the “Babel syndrome,” namely the idolatry of profit that sacrifices the weak, a uniformity that neutralizes differences, and the pretense that a single language — even a digital one — can translate everything, including the mystery of the person, into data and performance.”
The reference to rebuilding the walls of Jerusalem is maybe a bit less expected, but also very appropriate, and, in counterpoint to the Babel image, provides a picture of hope, one grounded in a way forward “rebuilds relationships before rebuilding with stones.”

Following, Charlie Camosy’s quick outline, as an initial reflection on the encyclical, Magnifica humanitas [“On Safeguarding the Human Person in the Time of Artificial Intelligence”], I thought it might be most helpful to approach these series of comments and reflections the way I typically approach a book review: develop a summary outline with some key highlights in order to provide readers with footholds to better navigate the text on their own. Magnifica humanitas is written in seven parts, somewhat unusually for an encyclical it is divided in five main chapters with an “Introduction” and “Conclusion.” I’ll begin this first post by giving an overview of the “Introduction.”
The “Introduction” opens with recognition that “Each generation inherits the task of shaping its own era” (§ 1). Where a generation guides “history to become a place where the dignity of every person is safeguarded, justice is promoted and fraternity is made possible” but it is nonetheless the case that “every era also runs the risk of creating an inhumane and more unjust world” (§1). The “Introduction” then continues on to discuss Pope Leo XIII and Rerum novarum with deep gratitude for having been the impetus for what is now called the Church’s Social Doctrine which “is a legacy of wisdom, where we find principles for thought, criteria for discernment and judgment, and concrete guidelines for action (§3).
From this Magnifica Humanitas then somewhat strikingly asserts “today we cannot limit ourselves simply to repeating [Pope Leo XIII’s] insightful teachings. Instead, we must ask God for the wisdom to interpret the great trends of our time, particularly technological advances” (§3. The “Introduction” makes clear that it is our collective and ongoing task in the age of AI “ to begin a shared discernment process for identifying the spiritual and cultural roots of ongoing transformations” (§5). We cannot “only on contingencies” because if we do “we risk letting the succession of emergencies dictate the direction of our path”(§5).
Toward the end “Introduction” concludes with bringing our attention to two images from the Hebrew Bible or Old Testament: The Tower of Babel and Nehemiah’s return & rebuilding of Jerusalem. Magnifica Humanitas draws out attention to the image of the city where the city is acting as a corollary for human technological “advancements.” These images of the city shows us what becomes of magnificent humanity when we try to build or create without God or against God: ruin, miscommunication, disunity.They also show us what becomes of magnificent humanity when we build and create with God and is consonance with God’s good world: rebirth, new creation, community. These two images point forward to the one of the final images in the Bible, of the new heaven and the new earth, of the Holy City, of the New Jerusalem (Rev. 21).
The “Introduction” finally concludes with an affirmation of “building for the common good” and “remaining human.” What the rest of the encyclical sets out to do and what it asks that we keep at the forefront of our minds is that “building for the common good means accepting the limits and weakness of humanity without considering them an error to be corrected”(§12). This is because we must remember that “ true fulfilment is not achieved by eliminating weakness but through harmonious growth’” and true fulfillment is only really “found where freedom and responsibility are intertwined with mutual care and true solidarity, and where progress is measured by the dignity of each person and the good of all peoples“ (§12). Because of this, it is imperative that we “lovingly safeguard the grandeur of humanity bestowed upon us and revealed in its fullness in Christ, the splendor of which no machine can ever replace”(§15). It is, after all, “the ‘rejected stones’ — the poor, the sick, the migrants and the least among us — [who] will become the cornerstone, and a solid, welcoming common home will emerge on the earth, where love and faithfulness will finally meet, and righteousness and peace will embrace” (§16).

Yes, Charlie, a long encyclical! I just finished skimming through citations. Many are what we might have expected: lots of citations to documents from the Second Vatican Council, the major documents of Catholic Social Teaching, and recent relevant documents and addresses. I’m excited that I see a reference to Tolkien’s “Lord of the Rings” (fn. 187), and interesting to see a reference to Hannah Arendt (fn. 143).

Quick overview of the structure. The encyclical has five chapters, the first two of which (“A Dynamic Approach Faithful to the Gospel” and “Foundations and Principles of the Social Doctrine of the Church”) are focused on methodology and almost giving the reader a primer on Catholic social teaching. There are 245 numbered paragraphs for the whole thing and the discussion of AI doesn’t really start until #97. There is a real attempt here to set up the theological and ethical framework before diving into the technology. Also, the encyclical is fairly long: the English version I have, when uploaded to Google docs, gives me 42,543 words…making it about four times longer than Rerum novarum. Significantly longer than Caritas in Veritate. But in the ballpark of the length of the encyclicals from Pope Francis.

I’ve only read the references, but what a joy to read a pope who doesn’t quote himself. His predecessors, Augustine, Hannah Arendt and Tolkien. This is going to be good.
