Pope Francis explained the origins of our Christmas crib:
“Let us go back to the origins of the Christmas crèche so familiar to us. We need to imagine ourselves in the little Italian town of Greccio, near Rieti. Saint Francis stopped there, most likely on his way back from Rome where on 29 November 1223 he had received the confirmation of his Rule from Pope Honorius III. Francis had earlier visited the Holy Land, and the caves in Greccio reminded him of the countryside of Bethlehem. It may also be that the “Poor Man of Assisi” had been struck by the mosaics in the Roman Basilica of Saint Mary Major depicting the birth of Jesus, close to the place where, according to an ancient tradition, the wooden panels of the manger are preserved.

The Franciscan Sources describe in detail what then took place in Greccio. Fifteen days before Christmas, Francis asked a local man named John to help him realize his desire “to bring to life the memory of that babe born in Bethlehem, to see as much as possible with my own bodily eyes the discomfort of his infant needs, how he lay in a manger, and how, with an ox and an ass standing by, he was laid upon a bed of hay”.[1] At this, his faithful friend went immediately to prepare all that the Saint had asked. On 25 December, friars came to Greccio from various parts, together with people from the farmsteads in the area, who brought flowers and torches to light up that holy night. When Francis arrived, he found a manger full of hay, an ox and a donkey. All those present experienced a new and indescribable joy in the presence of the Christmas scene. The priest then solemnly celebrated the Eucharist over the manger, showing the bond between the Incarnation of the Son of God and the Eucharist. At Greccio there were no statues; the nativity scene was enacted and experienced by all who were present.[2]
This is how our tradition began: with everyone gathered in joy around the cave, with no distance between the original event and those sharing in its mystery.
Thomas of Celano, the first biographer of Saint Francis, notes that this simple and moving scene was accompanied by the gift of a marvellous vision: one of those present saw the Baby Jesus himself lying in the manger. From the nativity scene of that Christmas in 1223, “everyone went home with joy”.[3]
With the simplicity of that sign, Saint Francis carried out a great work of evangelization. His teaching touched the hearts of Christians and continues today to offer a simple yet authentic means of portraying the beauty of our faith. Indeed, the place where this first nativity scene was enacted expresses and evokes these sentiments. Greccio has become a refuge for the soul, a mountain fastness wrapped in silence.
Why does the Christmas crèche arouse such wonder and move us so deeply? First, because it shows God’s tender love: the Creator of the universe lowered himself to take up our littleness. The gift of life, in all its mystery, becomes all the more wondrous as we realize that the Son of Mary is the source and sustenance of all life. In Jesus, the Father has given us a brother who comes to seek us out whenever we are confused or lost, a loyal friend ever at our side. He gave us his Son who forgives us and frees us from our sins.
Setting up the Christmas crèche in our homes helps us to relive the history of what took place in Bethlehem. Naturally, the Gospels remain our source for understanding and reflecting on that event. At the same time, its portrayal in the crèche helps us to imagine the scene. It touches our hearts and makes us enter into salvation history as contemporaries of an event that is living and real in a broad gamut of historical and cultural contexts.”
