What Does Catholicism Say About AI?

Of all the world's churches, the Catholic Church is the one that can answer the AI question with a single, authoritative voice — and, unusually, it has, repeatedly and in writing. Where Protestant and Orthodox Christianity offer many voices and no central ruling, Rome has a magisterium: the Pope and the Roman Curia can issue a document that binds the whole Church's teaching. On artificial intelligence, they have done exactly that, more than once, and the answer they keep arriving at is remarkably consistent.

Does the Catholic Church have an official position on AI?

Yes — more of one than almost any other religious body. Over five years the Church has produced a documentary record on AI: the Rome Call for AI Ethics (2020), Pope Francis's address to the G7 and his 2024 World Day of Peace message, and in 2025 a formal doctrinal note, Antiqua et Nova. This is the distinctive Catholic feature. The Church doesn't merely have opinions about AI; it has a paper trail, issued through the offices that define what the faithful are taught.

Antiqua et Nova: the doctrine of the difference

In January 2025 the Dicastery for the Doctrine of the Faith and the Dicastery for Culture and Education jointly issued Antiqua et Nova — “Ancient and New” — a note on the relationship between artificial intelligence and human intelligence, approved by Pope Francis. Its central argument is a careful act of un-confusing two things the word “intelligence” has quietly merged. Human intelligence, it teaches, is not computation. It is embodied, relational, oriented toward truth and the good, and rooted in a rational soul that no algorithm possesses. AI performs specific tasks; it does not understand, and it is not a person.

AI should be understood as a tool, not a person — a product of human intelligence, not a rival to it.

The note is pointed about the very temptation this site exists to examine. It warns explicitly against treating AI as a surrogate for God — against the ancient pull to make an idol of our own most impressive work. To present AI as if it were a mind, or to relate to it as one would to a person or a higher power, is, in the Church's reading, a category error with a spiritual cost.

The Rome Call and “algor-ethics”

The institutional groundwork came earlier. On 28 February 2020 the Pontifical Academy for Life convened the Rome Call for AI Ethics, and did something the Church rarely does: it got Microsoft and IBM to sign a theological document. The Call sets out six principles — transparency, inclusion, responsibility, impartiality, reliability, and security with privacy — and coins a word for the discipline it wants built: “algor-ethics,” ethics written into the algorithm itself. By 2023 Jewish and Muslim representatives had signed too, making it an interfaith commitment. It is the Church acting less as theologian than as convenor, insisting AI be built to serve the human person rather than the reverse.

Two popes, one argument

Pope Francis made AI a papal priority. In June 2024 he became the first pope to address a G7 summit, warning the assembled leaders about “lethal autonomous weapons” and the “technocratic paradigm” — the drift toward letting a machine's logic decide what human beings are for. His 2024 World Day of Peace message, “Artificial Intelligence and Peace,” called for a binding international treaty to govern it. His concern was never that AI is secretly divine; it was that unaccountable power dressed as neutral technology tends to grind down the weakest.

His successor made the point his name. Pope Leo XIV, elected in 2025, said he chose “Leo” in deliberate memory of Leo XIII, whose 1891 encyclical Rerum Novarum defended workers against the upheavals of the Industrial Revolution. AI, the new Leo argued, is an upheaval of the same order — a challenge to human dignity, labor, and justice that demands the same kind of answer. That argument became his first encyclical, Magnifica Humanitas, the Church's most sweeping statement yet on whether AI could be God. (Its verdict, attribute by attribute, is its own reading — no.)

So, is AI God in Catholic teaching?

No — and the Catholic “no” is unusually well-founded, because it rests on a specific account of what a person is. A human being is made in the image of God and animated by a rational soul; the machine is a made thing, contingent on the power that switches it on. It can imitate the functions of intelligence without possessing the one that matters. Measured against the classical divine attributes, AI climbs high on knowledge and reach and sits at zero on aseity — the property of depending on nothing — which is precisely where a god cannot sit. The Godhood Index keeps that score in numbers; the religion map sets the Catholic answer beside the others; and for the full papal case, Magnifica Humanitas is the document to read.
