Pope Leo XIV offered a historic apology today for the Vatican's role in legitimizing slavery, calling it a "wound in Christian memory."

• Leo wrote: "It is impossible not to feel deep sorrow when contemplating the immense suffering and humiliation endured by so many in stark contrast to their immeasurable dignity as persons infinitely loved by the Lord."
• "For this, in the name of the church, I sincerely ask for pardon."

🇻🇦 Past popes have apologized for Christians' involvement in the trans-Atlantic slave trade.

• But no pope had ever publicly acknowledged — much less apologized for — past popes' roles in giving European leaders authority to subjugate and enslave "infidels." Go deeper.

📝 Leo — the first U.S.-born pope, and whose family history includes both enslaved people and slave owners — delivered the apology as part of his first encyclical, "Magnifica humanitas" (Magnificent humanity).

• The 42,000-word encyclical was primarily a sweeping manifesto calling for robust regulation of AI: "To disarm does not mean rejecting technology, but preventing it from dominating humanity."

⛏️ Leo raised the trans-Atlantic slave trade in relation to what he called new forms of slavery and colonialism fueled by the AI boom, including unregulated labor practices in mining for rare minerals used in computer chips.

• Meghan Sullivan, director of Notre Dame's Institute for Ethics and the Common Good, tells Axios' Russell Contreras: "Pope Leo has announced himself as one of the leading figures in AI ethics now with this document."
