With this Letter, I wish to encourage the beautiful family tradition of preparing the nativity scene in the days before Christmas, but also the custom of setting it up in the workplace, in schools, hospitals, prisons and town squares. Great imagination and creativity is always shown in employing the most diverse materials to create small masterpieces of beauty. As children, we learn from our parents and grandparents to carry on this joyful tradition, which encapsulates a wealth of popular piety. It is my hope that this custom will never be lost and that, wherever it has fallen into disuse, it can be rediscovered and revived.
