Janina Gomes –
Pope Leo XIV’s first encyclical, Magnifica Humanitas, arrives at a moment when the world is dazzled by machines and unsettled by their power. In a time when artificial intelligence (AI), digitization and robotics are reshaping work, privacy, power and even the language of human dignity, the document reads less like a theological meditation and more like a moral warning for civilization.
At its core, the encyclical frames humanity’s technological future as a choice between two destinies: a new Tower of Babel, built on ambition without moral grounding, or a shared city where God and humanity dwell together in justice and fraternity. That contrast gives the text its force. It is not anti-technology. It is anti-indifference.
The central argument is simple but urgent: technology must remain accountable to the human person, not the other way around. Pope Leo XIV’s concern is not merely about devices or algorithms. It is about whether the tools of progress will strengthen human dignity or quietly erode it.
Work, dignity and disruption
One of the strongest threads in the encyclical is the future of work. Pope Leo XIV recognizes that AI can improve productivity, streamline services and create efficiencies across industries, but he also warns that the same systems can trigger large-scale displacement, deepen inequality and weaken the social value of labour.
This is where the encyclical speaks directly to governments and institutions. The Pope urges policymakers to prepare safety nets for workers and to adopt measures that protect the dignity of human labour. The concern is not nostalgia for a pre-digital past. It is a reminder that economies exist to serve people, not to treat workers as disposable inputs in a machine-driven system.
That message echoes the social teachings associated with Pope Leo XIII, whose 1891 encyclical Rerum Novarum helped shape modern Catholic thinking on labour and the rights of workers. By drawing that historical line, Magnifica Humanitas places the AI debate within a long moral tradition: each industrial revolution creates new forms of wealth, but also new risks of exploitation.
In that sense, the encyclical is remarkably contemporary. It understands that the question is no longer whether machines can do human tasks. The real question is what happens to society when machines begin to define the value of human work.
Bias, privacy and power
If the labour question is about economic survival, the ethics question is about moral survival. Pope Leo XIV warns that AI systems trained on existing data can inherit and amplify prejudice, producing algorithmic bias in areas such as hiring, healthcare and law enforcement. That is one of the sharpest warnings in the document, because it moves the debate beyond abstract ethics into daily life.
The concern is not hypothetical. In a world increasingly dependent on automated decision-making, bias is no longer just a flaw in code. It can become a structural injustice, hidden behind the appearance of neutrality. The encyclical suggests that technology can disguise old forms of discrimination in the language of efficiency and objectivity.
The Pope also raises the alarm over surveillance and the erosion of privacy. That anxiety reflects a broader truth about digital life: the more powerful the systems become, the easier it is for institutions and corporations to observe, classify and influence human behaviour. The encyclical treats privacy not as a luxury but as part of human dignity itself.
That is why the document repeatedly calls attention to the need for regulation, accountability and limits. Technology, it argues, should not be governed by the financial incentives of a few powerful actors, but should serve the common good. This is one of the encyclical’s most politically charged ideas, because it challenges a model in which innovation is celebrated while responsibility is outsourced.
A moral line on warfare
The encyclical also addresses one of the most dangerous frontiers of AI: autonomous weapons and combat decision-making. Pope Leo XIV states that it is not permissible to entrust lethal, irreversible decisions to autonomous algorithms. That line is not rhetorical ornament. It is a clear ethical boundary.
Here the Pope is arguing that human judgment must remain in command when life and death are at stake. Once that threshold is crossed, the risk is not only technical failure but moral abdication. A weapon may be automated, but responsibility cannot be.
This position places the encyclical firmly within a global debate about military AI, where speed and precision are often presented as strategic advantages, even as the ethical cost grows harder to ignore. In the document’s logic, the greater a machine’s capacity to decide, the greater the need for human restraint.
A church speaking to the world
One of the most striking features of Magnifica Humanitas is its insistence on dialogue. The encyclical calls the Church to engage “with all men and women of our time,” presenting dialogue as central to its vocation and to communion among the human family. That is a significant choice of tone. It refuses a narrow, inward-looking response to technological change.
Instead, the Pope positions the Church as a moral interlocutor in a global conversation involving governments, scientists, corporations and civil society. The message is that theology cannot remain sealed off from history. It must interpret events, test the direction of power and speak to the practical consequences of innovation.
This also explains why the encyclical repeatedly returns to the image of the Word made flesh. In Christian terms, that is the reminder that human identity is not self-invented through machines or markets. It is revealed through relationship, incarnation and moral responsibility. The document uses that theological center to answer a modern anxiety: what remains uniquely human when so much can now be simulated?
The Vatican’s broader line
The encyclical does not emerge in isolation. It stands in continuity with the Vatican’s recent engagement with AI ethics, including Pope Francis’s support for the Rome Call for AI Ethics, which emphasized transparency and human-centered design. Pope Francis also warned about deepfakes and the danger of machines replacing authentic human relationships and discernment.
Pope Benedict XVI is also invoked through his insistence that economic activity must be ordered toward the common good rather than reduced to commercial mentality. Together, these references create a clear doctrinal arc. The Church is not trying to win a technical argument about software. It is trying to preserve a moral language for a world increasingly shaped by systems that may be powerful, but not wise.
The encyclical’s language of Babel and Jerusalem gives that mission a vivid symbolic frame. Babel represents human grandeur without humility; Jerusalem represents communion ordered toward the common good. That contrast makes the document memorable because it is both ancient and immediate.
Why it matters now
What makes Magnifica Humanitas compelling is that it refuses both technological pessimism and naïve optimism. It does not deny the power of AI to heal, connect, educate and protect. But it insists that every new capacity creates a new moral obligation.
That is a timely message for a world where debates about AI often oscillate between market excitement and public fear. Pope Leo XIV is offering a third path: disciplined innovation shaped by ethics, law and respect for human dignity. He is asking whether society will build systems that serve people, or systems that gradually diminish them.
For policymakers, that means labour protections, algorithmic accountability and stronger oversight. For companies, it means designing technology around transparency and human impact rather than profit alone. For citizens, it means recognizing that the debate is not only about what AI can do, but about what kind of society it may create.
Magnifica Humanitas ultimately reads as a pastoral warning, a social critique and a civilizational appeal all at once. Its message is unmistakable: in the age of intelligent machines, the true measure of progress will not be computational speed, but whether humanity remains humane.
