It’s called Magnifica humanitas and the whole text is focused on protecting human dignity in the age of artificial intelligence. The timing they went with is pretty specific. The Pope signed the document on May 15, which is the exact 135th anniversary of Rerum novarum

• Pope Leo XIII’s famous 1891 text about the Industrial Revolution. Also, Christopher Olah, a co-founder at Anthropic who leads their interpretability research, is actually co-presenting the document alongside the Pope. This formally anchors the Vatican’s policy on AI to their historical stance on the Industrial Revolution, while bringing a leading AI safety researcher directly into a Church presentation.
