From Mirari vos (1832) to Magnifica humanitas (2026): The Development of Catholic Teaching on Communication, Technology, and Human Dignity

This article examines the development of Catholic reflection on media, communication, and technology from nineteenth-century debates over press freedom to contemporary interventions on artificial intelligence. Drawing on a purposively selected corpus of Catholic documents issued at the universal level between 1832 and 2026, it combines historical–hermeneutical reconstruction, comparative document analysis, and juridical–institutional interpretation. The study distinguishes three heuristic phases: defensive regulation and the construction of Catholic media institutions; pastoral appropriation, dialogue, media education, and digital adaptation; and, since 2020, an anthropological deepening accompanied by growing concern with the political, economic, juridical, and social structures of AI. Particular attention is given to the Rome Call for AI Ethics, the two papal messages of 2024, Antiqua et nova, and Magnifica humanitas. The article argues that this history does not reveal an unchanged doctrine of human dignity, but a developing anthropological concern whose vocabulary, theological grounding, and normative function change over time. Earlier concerns with truth, moral order, ecclesial responsibility, and the salvation of souls are progressively reformulated through communication as communion, participation, rights, human agency, and integral human development.
