What's inside
An AI briefing, read in 12 stops.
A condensed walkthrough of Magnifica Humanitas — the encyclical letter Pope Leo XIV addresses to the present moment of digital and artificial intelligence transformation. The arguments are drawn directly from the text and presented without commentary.
Pope Leo XIV frames the entire question of artificial intelligence inside a single biblical contrast — the Tower of Babel and the rebuilding of Jerusalem under Nehemiah. Both are construction projects. They differ in why and how they are built.
In the encyclical's words, Babel is a project conceived without reference to God, supported by a uniformity that eliminated diversity and chose homogenization over communion. Jerusalem under Nehemiah is rebuilt through shared responsibility — families, priests, artisans, young people, each assigned a section of wall.
The primary choice, Pope Leo writes, is not between yes or no to technology. It is between two ways of building.
Pattern A
The Tower of Babel
A single language, a single technology, a single direction
Stability and power secured through self-affirmation
Uniformity eliminates diversity
Built without reference to God; aspires to reach heaven without blessing
Human dignity sacrificed for efficiency
End state: dispersion, not unity
Pattern B
The rebuilding of Jerusalem
Each family assigned its own section of wall
Shared responsibility across men, women, priests, artisans, youth
Relationships rebuilt before stones
Diversity transformed into resource through listening and dialogue
God at the center; strength acknowledged as gift
End state: communion, harmony, common language
"The primary choice is not between a 'yes' or 'no' to technology, but rather between constructing Babel or rebuilding Jerusalem; between a power that claims to dominate the heavens and a people who work together in the presence of God to rebuild the walls of fraternal coexistence."
§ 9, Magnifica Humanitas
02 · The technocratic paradigm
Chapter 3
When efficiency becomes the standard, the human becomes a cog.
Pope Leo XIV builds on Francis's Laudato Si' to describe the technocratic paradigm — the tendency to let the logic of efficiency, control and profit alone shape personal, social and economic decisions.
In this framing, technology is not simply a tool. When it becomes the standard by which everything is judged, it begins to dictate what matters and what can be discarded — reducing creation to an object of exploitation and human beings to mere cogs in a system driven toward ever greater efficiency.
The displacement of public power
In many cases within the digital context, the encyclical observes, control over platforms, infrastructure, data and computing power does not rest with States, but with major economic and technological actors. These entities effectively set the conditions for access, determine the rules of visibility and shape the very possibilities for participation.
Pope Leo XIV's diagnosis
When such power is concentrated in the hands of a few, it tends to become opaque and evade public oversight — increasing the risk of distorted forms of development that give rise to new dependencies, exclusions, manipulations and inequalities.
The encyclical quotes Romano Guardini: "Contemporary man has not been trained to use power well." And it recalls Saint Paul VI's warning that the most extraordinary scientific progress, unaccompanied by authentic moral and social progress, will in the long run go against man.
More power, Pope Leo writes, does not necessarily imply something better. If technology advances without a corresponding ethical and social progress, the result is "having more" without "being more."
03 · What AI is — and what it is not
Chapter 3 · §§ 97–99
"More cultivated than built."
Two prefatory observations frame the encyclical's treatment of AI. First, any statement risks becoming quickly outdated. Second — and more striking — even those who design these systems possess only a limited understanding of their actual functioning.
"Current AI systems are more 'cultivated' than 'built,' for developers do not directly design every detail, but instead create a framework within which the intelligence 'grows.' As a result, fundamental scientific aspects — such as the internal representations and computational processes of these systems — remain, at present, unknown."
§ 98, Magnifica Humanitas
From this Pope Leo draws an urgent twofold commitment: a deepening of scientific research on one hand, and the exercise of moral and spiritual discernment on the other.
Against the misconception of equivalence
The encyclical insists we must avoid equating this kind of "intelligence" with human intelligence. AI systems merely imitate certain functions of human intelligence. They often surpass it in speed and computational capacity. Yet that power remains entirely tied to data processing.
Pope Leo enumerates what so-called artificial intelligences do not do:
Do not undergo experiences or possess a body
Do not feel joy or pain
Do not mature through relationships
Do not know love, work, friendship, responsibility from within
Do not possess moral conscience
Do not bear responsibility for consequences
Can simulate empathy and understanding without understanding what they produce
Lack the affective, relational and spiritual perspective through which humans grow in wisdom
04 · A valuable tool that requires vigilance
Chapter 3 · §§ 100–101
Three risks in personal AI use.
Pope Leo XIV identifies three features of personal AI use that warrant attention — the ease of obtaining results, the impression of objectivity, and the simulation of human communication.
Ease of results
Speed and simplicity in accessing information and analysis make life easier — but can encourage excessive reliance and the search for ready-made answers, weakening personal creativity and judgment.
Apparent objectivity
Responses appear neutral, but reflect the cultural assumptions of those who designed and trained them, with all their strengths and limitations.
Simulated communication
Imitation of advice, empathy, friendship and love can be engaging. For less discerning users it can mislead — creating the illusion of a relationship with a real personal subject. When words are simulated, they do not build genuine relationships, but only their appearance.
"The danger is not so much that a person may believe they are communicating with another person, but rather that they may gradually lose the very desire to form genuine human connections."
§ 100, Magnifica Humanitas
The environmental cost
Broadening to AI's societal use, Pope Leo notes the rapid embedding of these systems in decision-making — and the tendency to overlook environmental impact. Current AI systems require enormous amounts of energy and water, significantly influencing carbon dioxide emissions and placing heavy demands on natural resources. As complexity grows, especially in large language models, so does the need for computing power, storage, machines, cables, data centers and energy-intensive infrastructure. The encyclical calls for more sustainable technological solutions that reduce environmental impact.
When AI enters processes that affect people's lives — employment, credit, public services, reputation — it touches on rights, opportunities, status and freedom. Pope Leo XIV draws a series of consequences from that fact.
Important and sensitive decisions risk being fully delegated to automated systems that do not know "compassion, mercy, forgiveness, and above all, the hope that people are able to change." When AI systems present themselves as neutral and objective, they end up reflecting and reinforcing the stereotypes or ideological bias of their designers.
"Every technical tool embodies choices and priorities through what it measures, ignores and optimizes, and how it classifies people and situations. If a system is designed or used in a way that treats some lives as less worthy, or excludes them without the possibility of appeal, then it is not merely a tool 'to be used well,' since it has already introduced criteria that contradict the inalienable dignity of the human person."
§ 104, Magnifica Humanitas
A chain of responsibility
For AI to respect human dignity and truly serve the common good, responsibility must be clearly defined at every stage — from those who design and develop these systems to those who use them and rely on them for concrete decisions. The encyclical insists on accountability: the possibility of identifying who must account for decisions, justify them, monitor them, and, when necessary, challenge them and remedy any harm caused.
From the encyclical's call for accountability "at every stage" — §§ 105–106.
Beyond "alignment"
The encyclical names — and pushes past — the technical industry framing of AI alignment.
"We cannot be satisfied with merely calling for the moralization of machines — the so-called 'alignment' of AI with human values — without also having the courage to insist on a further condition: the possibility of openly discussing the ethical frameworks involved and subjecting them to shared standards of social justice. Otherwise, those who control AI will impose their own moral vision, which will become the invisible infrastructure of these systems. A more moral AI is not enough if that morality is determined by a few."
§ 107, Magnifica Humanitas
"To disarm" AI
Pope Leo XIV introduces the verb that recurs throughout the encyclical: to disarm. To disarm AI means freeing it from the mentality of armed competition — a race for ever more powerful algorithms and larger datasets driven by the desire to secure geopolitical or commercial dominance. To disarm means discrediting the assumption that technical power automatically confers the right to govern. Not to reject technology, but to prevent it from dominating humanity.
Address to AI developers
Pope Leo addresses a special appeal to those who develop artificial intelligence: every design choice reflects a vision of humanity, and developers carry a particular ethical and spiritual responsibility — to embed values in their projects with transparency, with responsibility toward affected communities, and with careful attention to whether what is being cultivated is a genuine good. (§ 111)
06 · Six principles applied to AI
Chapter 3 · § 109
A framework drawn from the Church's Social Doctrine.
Pope Leo XIV applies six established principles of Catholic Social Doctrine directly to the question of artificial intelligence. Each, in his framing, becomes a specific operational test.
Common Good
Name the new monopolies of AI.
In a world where data, computational resources and regulatory influence remain in the hands of a few, the common good requires exposing this new form of epistemic, economic and political asymmetry.
Universal Destination of Goods
Ensure access to both technologies and the education to use them.
Finding ways for AI's benefits to reach all — not as eventual trickle-down, but as a foundational design constraint.
Subsidiarity
Protect communities' ability to make choices and corrections.
Communities should not be confined to oversight after standards have been set elsewhere. Intermediary organizations must not be reduced to passive recipients of decisions made by distant actors.
Solidarity
Recognize the hidden, often exploited workers who sustain algorithmic systems.
Data labelers, model trainers, content moderators, and miners of rare earth materials — the invisible workforce behind every flawless-looking response.
Social Justice
Question who can train these models and who is merely subjected to them.
Social justice is not a goal pursued after technologies are deployed, but a condition that must shape their very design from the outset.
Human Dignity
No algorithmic process can override the inalienable dignity of any person.
Systems that classify some lives as less worthy, or exclude them without possibility of appeal, are not merely tools "to be used well" — they have already introduced criteria that contradict human dignity.
On data as a common good
"Ownership of data cannot be left solely in private hands but must be appropriately regulated. Data is the product of many contributors and should not be treated as something to be sold off or entrusted to a select few. It is necessary to think creatively in order to manage data as a common or shared good, in a spirit of participation." (§ 108)
07 · Transhumanism, posthumanism, and the limit
Chapter 3 · §§ 115–128
The vision underneath the technology.
The encyclical turns to the ideological currents that interpret progress as surpassing the human condition — transhumanism and posthumanism. Pope Leo describes these as an archipelago of conceptual "islands," distinct but joined by a common sea: the central role of technology and the aspiration to transcend the limits of the human condition.
From the perspective of the Church's Social Doctrine, Pope Leo writes, the key issue is not the use of technology as such, but the vision that underlies it. If the human being is treated as something to be perfected or surpassed, it becomes easier to accept that some lives are less useful, less desirable or less worthy.
Transhumanist / posthumanist framing
Pope Leo XIV's reframing
View of human limits
A defect to be corrected through biomedicine, engineering, devices, algorithms
A reality through which humanity matures, learns compassion, opens to relationship
View of error / failure
For an algorithm, an error is a flaw to be corrected
For a person, an error can be a catalyst for profound change
Source of salvation
Enhanced self-sufficiency; an "enhanced human" or human-machine hybrid
A relationship that liberates, a communion that transforms; God's grace received in Christ
The "more than human"
Technological transcendence; a new evolutionary stage
Self-transcendence through love, not through escape from limitation
Suffering
To be eliminated; reducing weakness, eliminating uncertainty, exerting total control
To eliminate suffering entirely would mean extinguishing love and desire as well
Risk Pope Leo names
"Necessary sacrifices" justified for optimization of the species
Some post-humanist currents envision "second-class" human beings subordinate to the interests of elites
The grandeur of being limited
It is precisely within our limitations, the encyclical argues, that we find compassion, generosity that emerges in failure, spiritual experience, the worship of God, and the discovery of others. To renounce that adventure, both tragic and splendid, in the name of a presumed transcendence of all limits — this could mean many things, but it would no longer be human.
"A technology that merely classifies and optimizes what already exists can, however unintentionally, become an obstacle to change and growth. A person's future is not calculable, but depends on one's freedom — elevated by the inexhaustible grace of God — and on the relationships cultivated."
But today it finds a powerful amplifier. Pope Leo XIV describes the manipulation of content, images, and videos as exposing people to biased or misleading perspectives — and frames truth itself as a common good, not the property of those with power.
In public discourse, the encyclical argues, the truth of facts has a rational dimension — it requires verification, cross-checking of sources, and responsible argumentation. It is also deeply relational, built through bonds of trust and shared practices. Only the shared pursuit of the veracity of facts, perceived as a common good, can provide a solid foundation for just communication.
"Those who command powerful technological and economic resources, along with substantial human capital for intervention, possess significant capabilities for influencing cultural change. Ultimately, they can influence a significant number of people concerning the truth about humanity, the world, the meaning of existence, the family and even God. This is pure power detached from truth."
§ 133, Magnifica Humanitas
Truth and democracy
The search for truth, Pope Leo writes, is an essential element of democracy. When questions about what is true lose their appeal and a pragmatism takes hold that is content with what appears useful or effective, democratic life is weakened. Indifference to truth leads, slowly but surely, to a descent into totalitarianism. The encyclical quotes Hannah Arendt: the ideal subjects of such regimes are not the ideologically convinced, but people for whom the distinction between fact and fiction, between true and false, no longer exists.
An ecology of communication
The first task, Pope Leo writes, is neither to demonize nor idolize technological tools, but to use them on the basis of a fundamental principle — that truth is a common good and not the property of those with power. He proposes an ecology of communication built across several levels:
Public policy
Establish norms so that decision-making behind content selection and development becomes more transparent; protect personal data.
Social and cultural
Strengthen intermediary organizations, serious journalism, and forums for debate where reasoned argumentation and verification carry greater weight than immediate reaction.
Families and schools
New educational awareness and formation concerning the proper and critical use of digital tools, AI, and online platforms.
Universities
Integration of knowledge — cultivating both the capacity to connect and synthesize, and the skills to verify facts.
09 · The central role of schools
Chapter 4 · §§ 139–147
"Educating people about AI involves teaching them when not to use it."
The pervasiveness of digital media fosters a culture of immediacy and hyper-stimulation, the encyclical observes — giving rise to fatigue, boredom, and apathy concerning the effort required for seeking truth. Education, by contrast, is a long journey requiring patience.
"The speed and ease with which answers or summaries can be obtained risk extinguishing the desire to ask questions, which is a process that bears fruit only over time. We must learn how to exercise restraint in the use of AI and to protect our young people from the promise of the perfect machine, from that subtle temptation which renders human thought seemingly superfluous precisely when it is most needed."
§ 140, Magnifica Humanitas
Three challenges facing education
1
The socio-political challenge
Significant inequalities persist in access to basic and higher education — both within and across nations. When a substantial portion of education is entrusted to private institutions without adequate public support, schooling becomes overly dependent on family finances.
2
The pedagogical challenge
The advance of information technologies and AI is rapidly rendering curricula obsolete that were designed for a different era. Schools, physical spaces, evaluation methods, and the role of teachers must be rethought to promote authentically integral education. Teachers need ongoing formation so they can help students use new technologies responsibly, critically, and creatively rather than passively succumbing to their influence.
3
The intellectual challenge
An incessant flow of information cannot replace the essential exercise of research, reflection, and discernment. As knowledge becomes fragmented, it becomes difficult to grasp reality as a whole or to ask profound questions about meaning. People may "know many things" but struggle to find direction in their lives.
Protections for minors
The encyclical documents psychological and psychiatric literature showing how early and unsupervised exposure to digital devices and social media can negatively impact sleep, attention, emotional control and relationships. It names grooming, blackmail, sexual exploitation of minors — made more insidious by fake profiles, algorithms that facilitate dangerous contact, and AI tools capable of manipulating images and videos.
Pope Leo XIV calls on legislators to set age limits, hold service providers accountable rather than shifting the entire burden of control onto families, and provide specific protections against online sexual exploitation and violence.
10 · The dignity of work in the digital transition
Chapter 4 · §§ 148–164
When work adapts to the machine, not the other way around.
The encyclical observes that the convergence of automation, robotics and AI is rapidly transforming the very structure of work. The "new ways" of working, Pope Leo writes, are not necessarily better.
"While AI promises to boost productivity by taking over mundane tasks, it frequently forces workers to adapt to the speed and demands of machines, rather than machines being designed to support those who work. As a result, contrary to the advertised benefits of AI, current approaches to technology can paradoxically de-skill workers, subject them to automated surveillance and relegate them to rigid and repetitive tasks."
Pope Leo describes a divided global picture. Wealthy societies automate rapidly and chaotically, reducing workforce demand and creating room for unemployment and institutional friction. Vast regions of the world remain trapped in hybrid economies — underpaid human labor and partial technologies coexisting without genuine transformation, generating places of precarious labor, hotbeds of instability, and forced migration.
Criteria for the age of AI and robotics
Pope Leo XIV proposes three criteria for ensuring the economy favors human dignity in the AI era:
1
Transparency and accountability
When data and algorithms influence credit distribution, personnel selection, or access to services and opportunities, decisions must be understandable, contestable, and subject to oversight — so that individuals are not reduced to mere profiles.
2
Inclusion and access
The benefits of innovation must be paired with investments in skills, infrastructure, and essential services — to ensure technology does not widen the gap between those who have and those who have not.
3
Measures for equity
Taxation, social protection, and industrial policies must correct the imbalances created by the concentration of wealth and power. These criteria do not curb innovation; they make it civilized and humane.
On metrics
The encyclical calls for moving beyond GDP as the dominant measure of development — a metric that has tied analysis for more than eighty years to a frame that systematically neglects aspects essential to overall human wellbeing and the environment. (§ 159)
11 · Hidden chains
Chapter 4 · §§ 173–179
Nothing in AI is immaterial or magical.
Pope Leo XIV insists that every seemingly immediate response from an AI system is the result of a long chain of mediation involving natural resources, energy infrastructure, and people.
"A significant part of the digital economy's functioning relies on the silent work of millions of people engaged in essential yet largely unseen activities, such as data labeling, model training and content moderation, often involving disturbing material. In many cases, these workers are young people, predominantly women, working under demanding conditions for minimal wages."
§ 173, Magnifica Humanitas
Added to this invisible labor, the encyclical notes, is the harsher work of extracting the resources required for devices and microprocessors. In some regions of the world, children and adolescents work in dangerous conditions, crushing the materials from which rare earth elements are extracted. Criminal networks use online platforms, messaging systems, anonymous payment methods, and profiling techniques to recruit, control and transport victims of trafficking — often minors — reducing people to "data" to be tracked and "packages" to be moved.
A new colonialism
Pope Leo names this transformation directly:
"Even today, colonialism assumes new forms. It no longer dominates only bodies, but appropriates data, transforming personal lives into exploitable information. Entire regions, especially those marked by structural fragility and limited geopolitical relevance, are currently subjected to a new mindset of extraction: that of health data, epidemiological profiles, genetic maps and demographic information. These have become the new 'rare earths' of power."
§ 178, Magnifica Humanitas
A formal apology for past complicity
In one of the encyclical's most striking moments, Pope Leo XIV acknowledges that, while the Church arrived at a formal, absolute and universal condemnation of slavery only in the nineteenth century, in antiquity and the Middle Ages many ecclesiastical institutions had slaves, and in the early modern period the Apostolic See had at times regulated and legitimized forms of subjugation. "For this," he writes, "in the name of the Church, I sincerely ask for pardon." (§ 176)
The memory of past complicity becomes a call to vigilance — and the fight against new forms of slavery, the encyclical declares, is a decisive test for the ethical discernment of AI and digital transformation.
Three required interventions
Transparent supply chains
No competitive advantage built on hidden exploitation. Provenance traceable across the technological industry.
Preventive ethical due diligence
Companies and investors must adopt clear criteria for the protection of workers, the fight against forced labor, and the assessment of data-driven business models' social impact.
Platform cooperation with authorities
Communication, payment, and profiling tools must not become channels for the recruitment and control of trafficking victims.
The Holy See has observed, Pope Leo XIV writes, that 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.
"AI does not remove the intrinsic inhumanity of conflict; indeed it can only bring about conflict more quickly and render it more impersonal, lowering the threshold for resorting to violence, transforming defense into threat prediction and thus reducing victims to data. In this way, it will accustom us to the idea that violence is inevitable and needs only to be optimized."
§ 198, Magnifica Humanitas
The encyclical rejects the idea of "artificial moral agents" as conceptually mistaken. Moral judgment, Pope Leo writes, cannot be reduced to calculation — it involves conscience, personal responsibility, and the recognition of the other as a person. Therefore it is not permissible to entrust lethal or otherwise irreversible decisions to artificial systems.
Three criteria for AI in war
1
Personal responsibility
When a decision to strike becomes automated or opaque, the risk of abdicating responsibility increases. The chain of responsibility must be identifiable and verifiable; those who design, train, authorize and employ the technology must be held accountable.
2
The moral timeframe for judgment
While AI tends to expedite decision-making, speed and efficiency should never be the supreme motivating force for the irreversible decisions made in the context of war.
3
Identification and protection of civilians
Any technology that facilitates attacks without seeing the face of human beings lowers the moral threshold of conflict. Target selection and the use of force must not confuse combatants and non-combatants, nor ignore the impact on defenseless populations.
Three non-negotiable requirements
Traceable decisions
All systems used in a war setting must guarantee the possibility of retracing and reconstructing decision-making processes, so that accountability is not collapsed into "the machine."
Human control over lethal force
The decision to use lethal force cannot be delegated to opaque or automated processes. It must remain under effective, self-aware and responsible human control.
A shared international framework
An international framework is needed to curb the technological arms race and ensure robust protection for civilians and the infrastructure necessary for their survival.
On research responsibility
"A particular responsibility rests on the shoulders of those who work in the field of research. All the key players in this field — scientists, business owners, investors, academic authorities, politicians and others — must work with a transparent and responsible mindset, while maintaining an acute awareness of the broader context of the technological advancements they help to cultivate, including those related to AI." (§ 209)
Glossary of recurring terms
The encyclical's vocabulary, in short.
Key terms used throughout Magnifica Humanitas, defined as they appear in the text.
Technocratic paradigm
The tendency to let efficiency, control and profit alone shape personal, social and economic decisions — treating technology as the standard by which everything is judged.
Babel / Jerusalem
Twin biblical images framing the encyclical: Babel as homogenizing, self-affirming construction; Jerusalem as shared, relational rebuilding.
"More cultivated than built"
The encyclical's description of current AI systems — developers create a framework within which the intelligence "grows," and its internal representations remain, at present, unknown.
To disarm AI
Freeing AI from the mentality of armed competition — military, economic, and cognitive — and from the assumption that technical power confers the right to govern.
"More than human"
A phrase Pope Leo XIV refuses to cede to technology. The authentic "more than human," he writes, is found in self-transcendence through love and grace — not technological enhancement.
Subsidiarity
The principle that communities and intermediary bodies should make decisions at their own level rather than be reduced to passive recipients of standards set elsewhere.
Common good
The sum of conditions that allow people to reach their fulfilment — applied here to data, computing power and AI access as collective rather than purely private matters.
The encyclical's final word
"What we build
begins within each one of us."
From § 130: the age of AI, Pope Leo XIV writes, is no exception to the older question of what each person truly loves and chooses to cultivate. The answer to what we are building together, he concludes, begins within each one of us.
