The title of Leo XIV’s first encyclical letter is Magnifica Humanitas — “on safeguarding the human person in the age of artificial intelligence". "The document will be published on May 25th and will bear the Pope's signature on May 15th, the 135th anniversary of the promulgation of Pope Leo XIII's encyclical Rerum Novarum. This date is far from coincidental: in 1891, Leo XIII addressed the social transformations of the first industrial revolution, and now Leo XIV is doing the same for the digital revolution. The paper will be presented on May 25th at 11:30 a.m. in the Synod Hall, with Leo XIV in attendance, marking the first time a Pope has addressed his own encyclical. The list of speakers is a proclamation of intent in itself. Cardinals Fernández and Czerny will speak, as will Durham University theologian Anna Rowlands, and Anthropic co-founder and head of research on the interpretability of artificial intelligence, Christopher Olah. Leo XIV is the first American pope and a former math student. Since his election in May 2025, he has consistently addressed the issue of AI. He has advised priests to refrain from using chatbots to compose homilies, advised young people to utilize AI in order to retain their ability to think independently, and reminded legislators from 68 countries that AI is a tool that serves humanity, not a replacement. In his statement on World Communications Day, he said that "faces and voices are sacred" and that the problem posed by AI "is not technological, but anthropological".
