Abstract
<jats:p>The monograph offers a comprehensive analysis of Pope Pius XI’s first papal radio message delivered on February 12, 1931, inaugurating Vatican Radio. The study situates the address within the broader context of Pius XI’s pontificate, emphasizing his innovative approach to mass media and his vision of communication as a tool for both evangelization and social engagement. The work reconstructs the historical, political, and technological circumstances that led to the establishment of Vatican Radio, highlighting the collaboration with Guglielmo Marconi and the significance of the Lateran Treaties. Particular attention is given to the universal scope of the papal message, which was directed not only to Catholics or Christians but to all people and all creatures, including God Himself. The monograph explores the theological, pastoral, and social dimensions of the address, analyzing its language, symbolism, and programmatic content. It also examines the reception and legacy of the message, demonstrating its relevance for contemporary discussions on the role of media in the Church and society. The study underscores Pius XI’s conviction that technological progress, exemplified by radio, should serve the common good, promote peace, and foster dialogue across religious and cultural boundaries.</jats:p>
