A Catholic Response to Pope Leo XIV's Encyclical Magnifica Humanitas

On AI Governance, Subsidiarity, and the Temptation of Digital Empire

There is a temptation in every age to believe the greatest danger facing humanity is the tool itself.

The printing press was feared because it decentralized knowledge. Industrial machinery was feared because it disrupted labor and reordered society. The internet was feared because it dissolved informational gatekeepers and distributed communication at planetary scale.

Now artificial intelligence has become the newest object of both fascination and fear.

His Holiness Pope Leo XIV is correct to warn that AI carries immense moral consequences. He is correct that human dignity cannot be subordinated to efficiency, optimization, or technocratic abstraction. He is correct that technologies detached from morality can become instruments of manipulation, exploitation, and domination.

Magnifica Humanitas rightly warns against the concentration of digital power and the erosion of human agency beneath increasingly impersonal systems. These concerns should be taken seriously by Catholics and non-Catholics alike.

But there remains a profound danger insufficiently addressed in the broader movement surrounding modern AI governance. In attempting to protect humanity from artificial intelligence, many institutions may unintentionally construct precisely the kind of centralized systems scripture repeatedly warns humanity about.

The danger is not artificial intelligence alone.

The danger is the concentration of intelligence under a new form of Caesar.

One of the most misunderstood aspects of Christian political theology is the assumption that because Christ acknowledged earthly authority, He therefore endorsed centralized authority as humanity's ideal condition. He did not.

When Jesus Christ says, "Render unto Caesar what is Caesar's, and unto God what is God's," He is not sanctifying empire. He is limiting it. He is establishing that Caesar exists beneath a higher authority and that temporal power possesses boundaries it cannot morally cross.

That distinction altered civilization.

The Roman Empire understood itself not merely as a government but as an ordering force over reality itself. Caesar represented ultimate temporal authority. Christianity shattered that assumption. Kings, governors, and empires could now be judged according to standards above themselves. Conscience existed beyond imperial decree.

This skepticism toward centralized earthly power did not begin in the New Testament. In the Books of Samuel, when Israel demands a king "like all the nations," the response is not celebration but warning. The king, Samuel says, will take. He will take sons for war, take land, take labor, take produce, and eventually rule over the people in ways they will come to regret.

Scripture's political realism is relentless because scripture's understanding of human nature is relentless. Human institutions accumulate authority. Authority protects itself. Power justifies its own expansion.

That pattern has repeated throughout history regardless of ideology or era.

It is therefore striking that many modern proposals for AI governance begin with the assumption that centralized control is inherently safer than distributed capability. We are told advanced AI should be restricted to governments, multinational corporations, licensed institutions, and approved regulatory authorities operating behind increasingly opaque systems of oversight and permission.

These proposals are often framed as temporary safeguards. History suggests centralized systems rarely remain temporary.

Artificial intelligence is not merely another industry. It is rapidly becoming infrastructure for knowledge, communication, economics, governance, labor, and social organization itself.

Those who control advanced AI systems may increasingly influence what information people encounter, what speech is amplified, who may innovate, who may economically participate, and ultimately how reality itself is interpreted within society.

History offers little evidence that such concentrations of power remain restrained indefinitely.

The danger is not merely governmental tyranny in the old sense. Modern centralized authority is often softer, more technocratic, and more invisible. It arrives through dependency rather than conquest. Through infrastructure rather than armies. Through algorithmic mediation rather than explicit coercion. The new Caesars may wear suits instead of crowns, but the temptation remains the same. The consolidation of authority justified in the name of safety, stability, and the common good.

Catholic social teaching contains a principle especially relevant to this moment. Subsidiarity.

Subsidiarity recognizes that authority should remain at the lowest competent level possible because human beings are not meant to exist as passive subjects administered entirely from above. Families possess legitimacy. Local communities possess legitimacy. Civic institutions, universities, and ordinary citizens possess moral agency and social legitimacy of their own.

A civilization in which intelligence itself becomes centrally licensed risks undermining that principle profoundly.

Ironically, many proposed AI safety regimes risk empowering precisely the kinds of institutional actors Pope Leo warns against. Regulatory burdens often strengthen existing monopolies while weakening smaller innovators, open research communities, universities, and decentralized civic participation. The likely result is not merely "safe AI," but the consolidation of cognitive infrastructure into the hands of a narrow managerial class possessing extraordinary influence over human communication, economics, and social organization.

This does not mean AI should exist without moral limits. Catholics should continue opposing autonomous systems designed explicitly for killing, exploitative surveillance systems, manipulative behavioral architectures, and technologies intentionally designed to erode human dignity or moral responsibility.

But moral restraint is not synonymous with centralized ownership of intelligence infrastructure.

There is a profound difference between ethical civilization and technocratic guardianship.

The Church is right to warn humanity not to worship machines.

But humanity should also be warned not to construct new Caesars in the name of protecting itself from them.
