Magnifica Humanitas Encyclical

The Philatelic and Numismatic Marketing Department presents the stamp issued by the Postal and Philatelic Service dedicated to Magnifica Humanitas, the first Encyclical Letter of Pope Leo XIV, signed on May 15, 2026. The document is devoted to safeguarding the human person in the age of artificial intelligence. Published at the beginning of his pontificate, the Encyclical offers a reflection on the greatness and fragility of the human being: on the one hand, every person possesses an eminent dignity, received from God; on the other, humanity is exposed to the profound transformations and new vulnerabilities of our time. At the heart of the document is the reaffirmation of the inviolable dignity of every person, created in the image of God and called to live in relationship with others, in solidarity and in care for creation. With particular attention to the challenges posed by modernity, Pope Leo XIV examines the rapid development of artificial intelligence and recognizes its extraordinary potential in the service of humanity. At the same time, he emphasizes the need to direct its development and use toward the common good. Artificial intelligence cannot be regarded as a purely technical or entirely neutral reality: its applications must be accompanied by responsibility, transparency, and appropriate governance mechanisms, so that technological progress does not give rise to new forms of inequality, exclusion, or violations of human dignity. The Holy See has also summarized the message of the Encyclical in the need to “disarm” artificial intelligence, removing it from logics of domination and violence. From this perspective, Magnifica Humanitas invites believers and non-believers alike to “remain human,” rediscovering that greatness of the human person which is expressed through responsibility, love, service, and solidarity. It is an invitation to build the future without succumbing either to naïve faith in technology or to fear of progress, but through discernment capable of bringing together innovation and responsibility, science and wisdom, progress and dignity. With this issue, the intention is to draw attention to a document of particular relevance to our times and to entrust philately with the transmission of a message addressed to all humanity: technology can contribute to building a better world only when it remains guided by the centrality of the human person, by responsibility, and by the pursuit of the common good. The stamp reproduces the moment when the Holy Father signed the Encyclical.
