May 18, 2026 : The Vatican announced Monday that Pope Leo XIV’s first encyclical will be published on May 25 with the title "Magnifica Humanitas".
Pope Leo will speak at a presentation for the release of the social encyclical — a papal letter to the Church — at 11:30 a.m. Rome time on May 25 in the Vaticanʼs Synod Hall.
The Vatican also confirmed that the full title of the encyclical is Magnifica Humanitas: “On the Protection of Human Dignity in the Age of Artificial Intelligence.” Magnifica Humanitas is Latin for “magnificent humanity.”
Leo signed the letter, which is expected to provide moral guidance on the digital revolution and emerging technologies such as AI, on May 15.
May 15 marked the 135th anniversary of the publication of Pope Leo XIII’s 1891 encyclical on capital and labor, Rerum Novarum, “Of New Things” — the first in a long line of social encyclicals produced in the modern era of the Catholic Church.
Pope Leo XIV indicated at the beginning of his pontificate that he intended to follow in the footsteps of his predecessor Leo XIII by responding to todayʼs industrial revolution: “developments in the field of artificial intelligence.”
