Encyclical Letter of His Holiness Leo XIV Magnifica Humanitas (15 May 2026)
Pope Leo XIV's encyclical Magnifica Humanitas, marking the 135th anniversary of Rerum Novarum, sets the Church's Social Doctrine—its dignity, common good, solidarity and subsidiarity—against the challenges of artificial intelligence. He warns that technology built on pride builds a new Tower of Babel, and calls instead for regulation, human-centered work, justice for workers and data subjects, an end to AI in lethal force, and a "way of Nehemiah" of shared rebuilding toward peace.
