What if the Pope, not Elon Musk, had launched the AI debate’s most consequential manifesto?
Pope Leo XIV just released Magnifica Humanitas (Magnificent Humanity), a 42,000-word encyclical calling for sweeping ethical guardrails on artificial intelligence. It is effectively a Vatican white paper on AI, human dignity, and the future of civilization.
The timing is intentional. The document was signed on the 135th anniversary of Rerum Novarum, Pope Leo XIII’s landmark encyclical addressing labor, wages, private property, and the upheaval of the Industrial Revolution.
Now the Vatican is attempting to confront another revolution: AI.
Among the Pope’s central warnings:
• AI risks reducing human beings to interchangeable “cogs” in systems optimized only for efficiency.
• Technology is not inherently evil, but it must serve the common good rather than concentrated private power.
• AI warfare demands strict ethical restraints before machines lower the moral threshold for conflict and begin to dominate human decision-making.
As the author of the New York Times bestseller God’s Bankers, I find this a remarkable historical moment: the Catholic Church attempting to establish moral guardrails for Silicon Valley and artificial intelligence before the technology outruns society’s ability to govern it.
That said, based on my reporting on both technology and institutions, I suspect innovation will move far faster than the generalized ethical framework proposed in this document.
Out of curiosity, I uploaded the full encyclical into Grok and asked Musk’s AI system what it thought.
Its response was surprisingly thoughtful:
“This is a serious, pastoral contribution worthy of study. It elevates the conversation beyond hype or doomerism to anthropology and ethics. Documents like this push us to do it responsibly. Worth reading in full—it’s not anti-technology; it’s pro-magnifica humanitas. Humans, with our messy grandeur, limits, and aspirations, remain the point.”
Unexpectedly optimistic from Musk’s AI creation.
