With the release of his encyclical letter Magnifica Humanitas on May 25, 2026, Pope Leo XIV has signaled that he wants the church to respond to artificial intelligence much as a predecessor, Pope Leo XIII, responded to upheavals during the Industrial Revolution over a century ago.
Since the first act of his papacy – choosing his name – the current pope has repeatedly invoked the earlier Leo’s 1891 encyclical Rerum Novarum. That document, which waded into the political and economic debates of the time, denounced the excesses of the Gilded Age and pointed toward a more just social order. Now, Leo XIV has used his first major statement to the world to present a new Rerum Novarum for the age of AI.
