Pope Leo XIV signs first AI encyclical on the 135th anniversary of Rerum Novarum
The 42,300-word 'Magnifica Humanitas,' released May 15, frames AI as this generation's labor displacement — a direct parallel to the industrialization Leo XIII addressed in Rerum Novarum — and warns that AI built by a small elite cannot serve the common good, calling for oversight across governments, religious communities, and civic institutions. Anthropic co-founder Chris Olah co-presented at the Vatican Synod Hall, the first time a pontiff has personally introduced an encyclical at publication, marking the first formal dialogue between frontier AI builders and Catholic institutional authority.

Pope Leo XIV, Magnifica humanitas
Why this matters
- → Pope frames AI displacement as this generation's labor crisis, directly paralleling industrialization that prompted Rerum Novarum 135 years ago.
- → AI concentrated in few hands widens digital divide; encyclical demands public oversight and shared responsibility to protect common good.
- → First papal encyclical co-presented by AI researcher signals institutional shift: Church now directly engaging frontier tech builders on ethics.
