The document starts from the premise that humanity faces a moral choice: to build a new Tower of Babel, marked by power, uniformity, profit, and technological domination, or to rebuild a symbolic Jerusalem, based on shared responsibility, human dignity, justice, and communion. Its central argument is that technology is not neutral. It carries the interests of those who design, finance, regulate, and use it. AI must be developed according to principles of human dignity, foster the common good, social justice, and solidarity. The encyclical criticizes the concentration of digital infrastructure, data, platforms, and computing power in the hands of a small number of global private actors because this can create new forms of dependency, exclusion, manipulation, and inequality. This encyclical treats AI as a historic transformation comparable to industrial policy questions and the tensions between capital and labor raised by Pope Leo XIII in his encyclical Rerum Novarum, published in May 1891. Participation of Anthropic Christopher Olah, co-founder of Anthropic and head of AI interpretability research, was one of the official speakers at the presentation of the encyclical, alongside cardinals, theologians, and academics. Olah highlighted three challenges: responsibility toward the poor and global inequality; the need to rethink human and family flourishing in a world mediated by AI; and ethical discernment among the creators of AI models themselves. Officially, the encyclical was signed on 15 May 2026, the 135th anniversary of Pope Leo XIII’s promulgation of Rerum Novarum on 15 May 1891, and presented on 25 May 2026 in the Synod Hall, in the presence of Pope Leo XIV. Leo XIV stated that Magnifica Humanitas “was born from listening”: listening to scientists and engineers, political leaders, public servants, parents, teachers, victims of algorithmic exclusion, and concerns surrounding autonomous weapons. What is the function of an encyclical? An encyclical is a papal letter carrying substantial doctrinal and pastoral weight. It is not simply an opinion article or a technical regulation. Its purpose is to guide the Church — and all people of goodwill — on moral, spiritual, social, and political issues relevant to a given era. In the case of Magnifica Humanitas, its role is to place AI within the tradition of the Church’s social justice doctrine. The document itself states that it does not intend to offer a technical treatise on AI but rather to introduce essential moral and social criteria for discernment into the global discussion. In practical terms: the encyclical does not say which algorithm to use, which law should be adopted, or which technical architecture should be implemented. It provides a normative framework: human dignity, responsibility, transparency, public oversight, social justice, peace, protection of vulnerable populations, and opposition to the logic of technological domination. Has there been a technology-focused encyclical before? Not exactly in this format. There have been previous social encyclicals addressing technical, economic, and industrial transformations, but Magnifica Humanitas appears to be the first papal encyclical dedicated systematically to artificial intelligence. The most important precedent is Rerum Novarum by Pope Leo XIII in 1891, which responded to labor issues and industrial transformation. Laudato Si’ by Pope Francis also criticized the “technocratic paradigm” and addressed science, technology, and ecology, but it was not specifically focused on AI. Magnifica Humanitas itself references recent AI-related documents, including the 2025 note Antiqua et Nova, messages from Pope Francis on AI and communications, and speeches on AI delivered at the G7. However, these were not encyclicals exclusively centered on the topic. The political force of the document lies in shifting the AI discussion from innovation to power. The encyclical does not merely ask whether AI will be efficient, productive, or competitive. It asks: who controls this technology, who profits from it, who becomes vulnerable, who is excluded, and what kind of humanity is being built. Christopher Olah’s presence from Anthropic makes the launch more relevant because it creates a direct bridge with the frontier AI industry. The Vatican is signaling that AI cannot be governed without its creators — but neither can it be governed only by them. While other Popes had previously made references to technology’s impact on humanity, this is the first encyclical that addresses technology in a direct and systematic way. Some of the predecessors are: John Paul II — Redemptor Hominis, 1979.This is probably the strongest earlier example. John Paul II explicitly asked whether technological progress was matched by moral and spiritual progress, and whether humanity was being elevated or degraded by its own technical achievements. He linked technology to domination, exploitation, imperialism, and the risk that material progress could be used against human dignity. This makes Redemptor Hominis an important precursor to later Catholic teaching on technology and the human person. Link to encyclical in the Vatican site. Benedict XVI — Caritas in Veritate, 2009.Benedict XVI treated technology within the broader question of “integral human development.” His concern was that development cannot be reduced to economic growth, efficiency, or material progress; it must include the moral, spiritual and social dimensions of the person. This is very close to the logic later used in debates on AI: technology must serve the whole human person, not replace human judgment or reduce human beings to data, productivity, or utility. Link to document on the Vatican website. Francis — Laudato Si’, 2015.This is the most important recent precedent. Francis did not write an encyclical “on technology” as such, but he made the technocratic paradigm central to his critique of modern civilization. He warned against a worldview in which technological and economic power are treated as if they automatically produce truth, goodness and progress. In Laudate Deum, he later summarized that critique again, saying that the technocratic paradigm reflects a distorted way of understanding human life and activity. Vatican Previous Popes did address technology’s impact on humanity in encyclicals, especially Leo XIII, John Paul II, Benedict XVI and Francis. But a full encyclical structured around artificial intelligence as a defining civilizational question is new. AI not as a side topic, but the central question of our times, comparable to the industrial policy question addressed by Pope Leo XIII in his Rerum Novarum, on the rights and duties of capital and labor, in May 1891. The function of an encyclical is twofold. For the Church, an encyclical is one of the most authoritative forms of ordinary papal teaching. It does not usually define new dogma, but it gives doctrinal, moral and pastoral guidance to bishops, clergy, theologians, Catholic institutions and the faithful. In social encyclicals, it helps the Church interpret the “signs of the times” through the Gospel and through Catholic social justice doctrine. It sets criteria for conscience, teaching, pastoral action, education, advocacy and public witness. For society, an encyclical functions as a moral intervention in public debate. It is often addressed not only to Catholics but also to “all people of good will.” It frames the ethical question: what protects human dignity, what serves the common good, what threatens the vulnerable, and what kind of society is being built. That is why encyclicals such as Rerum Novarum, Pacem in Terris, Populorum Progressio, Laudato Si’ — and now Pope Leo XIV AI-focused text — are important for international law frameworks and policymakers. They show how the Catholic Church continues to be relevant and influences the global debate about labor, peace, development, ecology, technology and human rights. The encyclical’s function is to tell both the Church and society that AI is not merely an innovation and productivity issue. It is a human, moral, political and spiritual que
