"Mystery" is a theological concept that is translated from the Greek word "mustérion." [1] Mysterious, mystical, secret, divine, not fully revealed. This sort of ineffable, irreducible truth you can touch but cannot fully grasp.

The reaction of astronauts to seeing Earth from space -- the mystery of creation. Parents seeing pieces of themselves echoed in their children who are nonetheless distinct and surprising -- the mystery of the person.

Much of the meditations in the encyclical are related to human dignity and fraternity. An example:

> Finitude, when truly accepted, does not diminish us but opens us to recognizing the face of God and others. Indeed, precisely because we experience limits — vulnerability, suffering and failure — we can recognize the inviolable dignity of every person, both our own and that of others.
