ENCYCLICAL LETTER
MAGNIFICA HUMANITAS
OF HIS HOLINESS
POPE LEO XIV
ON SAFEGUARDING THE HUMAN PERSON
IN THE TIME OF ARTIFICIAL INTELLIGENCE
INTRODUCTION
1. Humanity, created by God in all its grandeur, is today facing a pivotal choice: either to construct a new Tower of Babel or to build the city in which God and humanity dwell together. Each generation inherits the task of shaping its own era, of guiding history to become a place where the dignity of every person is safeguarded, justice is promoted and fraternity is made possible. Yet every era also runs the risk of creating an inhumane and more unjust world. Whenever humanity is in danger of marring its true identity, we Christians lift our eyes to the Incarnate God, knowing that it is “only in the mystery of the Word made flesh that the mystery of humanity truly becomes clear.” [1] In Jesus Christ, this humanity in its grandeur becomes the Way, the Truth and the Life, opening the path for each of us to grow toward fullness.
2. Founded on Christ, the living stone, we experience the powerful and mysterious action of the Holy Spirit, and we believe that every authentic human effort to cooperate with him for the good will be blessed by our heavenly Father, in whom we place our hope. For this reason, we can diligently contribute to every initiative that builds a more just world, and we can call others to collaborate in promoting the integral development of every human being. We wish to engage in dialogue with all men and women of our time, with whom we share in the events, questions and aspirations of humanity. [2] Together with them, we seek to identify new paths for the common good and for promoting a dignified life for all. Indeed, openness to dialogue is an integral part of the Church’s vocation because, constituted in Christ as “a sacrament… of communion with God and of the unity of the entire human race,” [3] she recognizes history as the place where the Gospel challenges and directs human experience.
3. In this spirit, Pope Leo XIII published his Encyclical Rerum Novarum in 1891, the 135 th anniversary of which we celebrate with deep gratitude this year. With that document, my beloved predecessor gave impetus to the reflection on society, the economy and politics, which is now known as the “Social Doctrine of the Church.” When some objected that the Church should not waste energy on worldly matters, but instead focus on communicating the message of eternal life, Leo XIII responded with realism and wisdom, saying that the proclamation of the Gospel cannot overlook the concrete lives of people. [4] Many decades have passed since then, and the Magisterium, pastors, theologians and faithful have continued to reflect on social issues in the light of the Gospel. Today, the Social Doctrine of the Church is a legacy of wisdom, where we find principles for thought, criteria for discernment and judgment, and concrete guidelines for action. Founded on Sacred Scripture and Tradition, and in engagement with the sciences, it helps us clearly interpret the challenges of the present and identify appropriate ways for living out a clear Christian witness, with joy and in service to the world. It is not an inert set of concepts, but a living corpus of truth that safeguards and interprets humanity’s vocation to a full and just life. I therefore wish to add my own voice to this living tradition, invoking the help of the Spirit of wisdom, who has dwelt in the world since its beginning (cf. Prov 8:22-31).
The res novae of our time
4. While Leo XIII spoke in his time of “new things” ( rerum novarum), today we cannot limit ourselves simply to repeating his insightful teachings. Instead, we must ask God for the wisdom to interpret the great trends of our time, particularly technological advances. In recent years, it has become increasingly evident how rapidly and profoundly digitalization, artificial intelligence (AI) and robotics are transforming our world. Technology should not be considered, in itself, as a force antagonistic to humanity. On the contrary, it has formed part of our history since the beginning as “a profoundly human reality, linked to the autonomy and freedom of man.” [5] Over the centuries, technological development has significantly improved the living conditions of humanity. At the same time, each phase of progress has also revealed the ambiguity of tools that can cause harm when not oriented toward the good. Today, however, we find ourselves facing a new situation. The power and prevalence of emerging technologies are interwoven into the fabric of daily life, shaping decision-making processes and deeply affecting the collective imagination: “Never has humanity had such power over itself.” [6] New technologies open up a horizon extending in directions that are imaginable but not yet fully predictable. This complicates the assessment of their potential impact and the long-term effects they may have on both the dignity of individuals and the common good.
