The pope signed “Magnifica Humanitas” (“Magnificent Humanity”) on May 15, the 135th anniversary of the publication of the landmark social encyclical “Rerum Novarum.”

The Vatican announced Monday that Pope Leo XIV’s first encyclical will be published on May 25 with the тιтle 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 тιтle 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.

The speakers at the encyclicalʼs presentation will be: Cardinal Víctor Manuel Fernández, prefect of the Dicastery for the Doctrine of the Faith; Cardinal Michael Czerny, SJ, prefect of the Dicastery for Integral Human Development; Anna Rowlands, professor of ethics and political theology at the University of Durham in the United Kingdom; Christopher Olah, co-founder of Anthropic USA; and Léocadie Lushombo, it, professor of theological ethics at the Jesuit School of Theology at Santa Clara University in Berkeley, California.
