Marking the 135th anniversary of the encyclical Rerum novarum, Pope Leo XIV issued his first encyclical, Magnifica humanitas: On the Protection of the Human Person in the Age of Artificial Intelligence. The encyclical Magnifica Humanitas, or, in translation, Magnificent Humanity, was published on 25 May 2026. In it, the Pope called for the protection of humanity, the promotion of truth, the dignity of work, social justice and peace.
Incidentally, the aforementioned encyclical Rerum novarum is an encyclical published by Pope Leo XIII, the predecessor of the current pope, on May 15, 1891, and concerns the relationship between the working class, capital, and labor during the Industrial Revolution. Magnifica humanitas: On the Protection of the Human Person in the Age of Artificial Intelligence, or rather, on the Protection of Human Dignity in the AI Era, nicely builds on Rerum novarum in a new context, but also on Pope Francis’ 2015 encyclical Laudato si (Praise be to you), which addressed climate change as another urgent problem facing humanity. Even more significantly, this is the first encyclical of Pope Leo XIV (real name Robert Francis Prevost), which gives it added weight.
Some media outlets and authors have called this text the Vatican AI manifesto. Some have interpreted it as the Pope's message that AI is not bad, and some have interpreted it as the Pope's criticism of artificial intelligence and a warning. However, it is very difficult to take the time today to go through at least some of the five chapters of this encyclical of about 200 pages. The story of artificial intelligence is only one part of the message. The larger part actually concerns the questions of the importance of truth for democracy, the place of man and what man is.
It is interesting that Pope Leo XIV in Chapter 5, entitled The Culture of Power and the Civilization of Love, under the section Building a Civilization of Love – Each of us can do our part, quotes Tolkien's Lord of the Rings, a favorite work of AI despots, especially Palantirovans:
“The twentieth-century Catholic author, JRR Tolkien, in the words of the protagonist of one of his novels, described our responsibility this way: ‘It is not our task to master all the tides of the world, but to do what is in us for the good of the years in which we are placed, eradicating evil in the fields we know, that those who live after may have a clean earth to till.’”
