Marking the 135th anniversary of Pope Leo XIII’s “Rerum Novarum“, (On Capital and Labour), on 25 May 2026 Pope Leo XIV released his first encyclical “Magnifica Humanitas: On Safeguarding the Human Person in the Time of Artificial Intelligence.’ An overview is given in Vatican News; This commences:

“Pope Leo XIV has taken up the legacy of his predecessor, writing a social encyclical which addresses one of the principal challenges of the contemporary age: artificial intelligence. Divided into five chapters, Magnifica humanitas has an underlying premise: technology is not ‘a force antagonistic to humanity’, nor is it ‘inherently evil’. However, ‘technology is never neutral, because it takes on the characteristics of those who devise, finance, regulate, and use it’. He appeals for the safeguarding of humanity, promotion of truth, dignity of work, social justice, and peace”.

The five chapters are:

• “A Dynamic Approach Faithful to the Gospel”—traces the Social Doctrine of the Church in recent magisterium and the Second Vatican Council, highlighting “its dynamic character”.
• “Foundations and Principles of the Social Doctrine of the Church”. These foundations, he says, include the dignity of the person, created in the image and likeness of God. It is important to recall this since “the pressure of new ideologies or certain highly powerful interests” can reduce the human person to “a resource to be used and exploited” or “on what they achieve or produce”.
• Technology and Dominance. The Grandeur of Humanity in Light of the Promises of AI stresses the need to approach artificial intelligence with vigilance. Pope Leo warns about the “technocratic paradigm” already denounced by Pope Francis and how it can require that every choice be dictated exclusively by measuring efficiency and profits.
• Safeguarding Humanity at a Time of Transformation. Truth, Work, Freedom—the Pope calls for an “ecology of communication” based on truth. He urges transparency in how content is selected, protection of personal data, serious journalism founded on argumentation and verification, a new awareness in the “proper and critical” use of digital tools, and the integration of different forms of knowledge.
• The Culture of Power and the Civilization of Love—Pope Leo XIV turns to war, saying “the digital revolution is changing the nature of conflict.” The Pope calls for an ethical approach, without which decisions about the life and death of persons will become increasingly impersonal due to a use of force regarded as an “immediate and viable option”.

Artificial Intelligence 

Pope Leo XIV indicates that it is not his intention to offer a comprehensive treatment of artificial intelligence, nor to give an overview of the extensive relevant literature, since authoritative contributions already exist, including within the ecclesial context (reference [123]). He limits himself to recalling a few essential elements for a moral and social discernment that safeguards the primacy of the human person, in order to ensure that it will always be human intelligence, with its conscience and freedom, that guides technical innovations and responsibly determines their use and limits. He comments [emphasis added]:

• It is appropriate to preface this discussion with two considerations. First, any statement regarding AI risks becoming quickly outdated, given the remarkable pace at which these systems are developing. Second, all of us, including those who design them, possess only a limited understanding of their actual functioning. Indeed, current AI systems are more “cultivated” than “built,” for developers do not directly design every detail, but instead create a framework within which the intelligence “grows.” As a result, fundamental scientific aspects — such as the internal representations and computational processes of these systems — remain, at present, unknown. There thus emerges an urgent need for a twofold commitment: on the one hand, a deepening of scientific research; on the other, the exercise of moral and spiritual discernment.
• It is not possible to provide a single, comprehensive definition of AI. What can be stated, however, is that we must avoid the misconception of equating this type of “intelligence” with that of human beings. These systems merely imitate certain functions of human intelligence. In doing so, they often surpass human intelligence in speed and computational capacity, offering tangible benefits across many fields. Yet this power remains entirely tied to data processing. So-called artificial intelligences do not undergo experiences, do not possess a body, do not feel joy or pain, do not mature through relationships and do not know from within what love, work, friendship or responsibility mean.
• Nor do they have a moral conscience, since they do not judge good and evil, grasp the ultimate meaning of situations, or bear responsibility for consequences. They may imitate language, behaviour and analytical skills, or even simulate empathy and understanding, but they do not understand what they produce, for they lack the affective, relational and spiritual perspective through which human beings grow in wisdom. Even when these tools are described as capable of “learning,” their way of doing so is different from that of a human person. It is not the experience of those who allow themselves to be shaped by life and grow over time through choices, mistakes, forgiveness and fidelity. Rather, it is a form of statistical adaptation based on data and feedback, which can be very effective, but does not imply inner growth.
