Read the Full Encyclical →

Magnifica Humanitas is the first encyclical of Pope Leo XIV. In it, the Holy Father takes up the question Pope Leo XIII faced at the dawn of the industrial age — what becomes of the human person when the machinery of the world is remade — and asks it again of our own century’s defining technology.

The Vatican’s Dicastery for Promoting Integral Human Development has translated the encyclical into a five-card visual summary, presented here in full. Each card is reproduced as published — visit the Dicastery for the original PDFs, translations in other languages, and ongoing resources.
