The beautiful custom of setting up mangers to commemorate the birth of the Infant Jesus was started by St. Francis of Assisi.
It was the year 1223. St. Francis went to Rome to obtain from Pope Honorius III authorisation to celebrate Christmas in a totally new way. St. Francis chose a forest in the vicinity of the village of Grecio, in the region of Umbria, not too far from Rome, where a good friend of his lived, the noble Giovanni Velita.
About 15 days before Christmas, St. Francis said to him: ‘If you want to celebrate the feast of the Divine birth in Grecio make haste to prepare what I indicate to you.
‘So that we can properly remember the circumstances in which the Divine Child was born and all the inconveniences he endured as he lay in the manger on straw between an ox and a ass, I would like to re-create this in a palpable way, as if I had seen it with my own eyes.’
Many religious and the residents of Grecio and the surrounding area were all invited for this special commemoration. Just before midnight, the Franciscan friars went in procession to the spot chanting the antiphons of Advent. They were accompanied by the villagers who carried flaming torches.
The wind blew strongly and the light of the torches projected their flickering shadows on the dense forest. However, in the clearance where the crib had been setup, there reigned an ambience of sacrality and peace; Only the cold was a nuisance.
When the village bell of Grecio began to toll midnight, a priest began to celebrate Mass. The altar had been placed in front of the crib with the ox and ass on either side. A beautiful full-size statue of the Child Jesus rested on the straw.
As is well known, St. Francis never wanted to be ordained a priest out of humility. Because of this, as deacon, it was his duty to solemnly sing the Gospel of that Christmas mass.
After the reading of the Gospel, all waited attentively to hear the sermon that St. Francis himself gave on the grandeurs and mercies of the Saviour of the human race, who that night was made flesh and dwelt among us.
St. Francis spoke words with a supernatural sweetness about the poverty in which the God-man was born and about the insignificant city of Bethlehem. It is difficult to imagine the fiery love that the sweet, clear, and sonorous voice of St. Francis produced in the hearts of those privileged to hear him.
At the end of his sermon, St. Francis bent over to kiss the statue of the Divine Child. At this moment a miracle took place that only he and Giovanni Velita saw. The statue became alive. It was as if it had been woken from a profound sleep with St. Francis’s kiss, and then the Child Jesus smiled at St. Francis.
At the consecration, when the bread and wine truly become the Body, Blood, Soul, and Divinity of Our Lord Jesus Christ, St. Francis was able to contemplate the Messiah in two ways: in the form of the Holy Eucharist and laying in the manger.
At the end of the solemn midnight mass, and after having incensed the manger, the friars returned to Grecio and the villagers to their homes. Everyone was full of supernatural joy.
The veracity of this event can be certified by the sanctity of the one who experienced it, as well as by the miracles that happened afterwards. The straw from the manger was carefully kept by the people and was an efficacious remedy to miraculously cure sick animals and an antidote against many other diseases.
This devout and hitherto unknown institution of the manger was enthusiastically received by the faithful. St. Clare of Assisi, disciple of the saint, established it in her convents. Every year she setup the manger herself.
From the majestic cathedral to the simplest rural chapel, from the palace or mansion to the humblest abode, the Catholics of the whole world, since that time, have had the pious custom of setting up a manger. In this way they repeat the custom that Providence inspired from the seraphic St. Francis of Assisi in the remote year of 1223.
