In some circles, it is not well known that Maria Montessori was Catholic. Two of her writings specifically addressed her Catholic Faith: The Mass Explained to Children and The Child in the Church.
What follows is an excerpt taken from her 1930 edition of The Child in the Church, on the topic of Instruction of the Holy Mass in the Atrium.
“As Dr. Montessori is at present engaged in the preparation of a children’s Missal, her ideas as to how best little children should be taught to understand and participate in the Holy Mystery of the Mass, will be only cursorily touched on here.1. “
Suffice it to say that the Dottoressa regards this matter of such importance that she would arrange all the work of the Atrium to be, as far as possible, Misso-centric. “For,” she says, “just as all the child has to learn in the various multiplication tables is found in, and summed up by the ‘Table of Pythagoras,’ so all that is essential in Christian instruction is, in some way or other, connected with or summed up in the great central rite of the Mass.
This may seem a strange statement to Protestant readers, but that is because they do not realize the significance of the Holy Eucharist to Catholics. For the Mass is, as it were, the meeting place and summing up of many different lines of thought and action. It may indeed be compared to a diamond with innumerable different facets, so that from whatever point of view it is subjected to the light of thought, it reflects back a fresh significance. Thus, historically, it may be regarded as the consummation of the Old Law, and the beginning of the New Testament. It is the Sacrifice of the new Law, daily offered up for the sins of the world. Looked at in another way, it is a marvellous (sic) epitome of the Birth, Life, Death, and Resurrection of Our Lord. In the prayers and readings of the book of the Mass (i.e., the Missal) the Church has preserved for us the most beautiful hymns and prayers of the Saints, and the very quintessence of the Scriptures. In the ceremonies and setting of the Mass, all the arts – music, poetry, painting, sculpture, architecture, even the drama – have given of their best to pay homage to the Supreme Artist. The common elements of life – bread and wine and water are taken up in It as essentials; and the most precious products of the earth – the spices of the East, gold and silver and precious stones – are added thereto in the vain hope of making a setting worthy of the Eucharistic miracle. The Mass forms the common focus of our collective worship, but is at the same time to us, as individuals, our Daily Bread. But It is not only the meeting place of all Catholic worshippers (sic) on earth; for, in the Holy Sacrifice, the Church Militant is united to both Church Triumphant and the Church Suffering – the Angels and Saints in Heaven fall down before the Sacred Host on the Altar, and the merits of Him Who is offered there are applied to the Souls in Purgatory.
These are only some of the aspects from which the Holy Mass can be considered. They can all be summed up in the saying that in the Mass we have Emmanuel – God with us. Here, in sacramental form, we have the continuation of the sublime mystery of the Incarnation. And this is why the Mass is, and has always been, the central dynamo from which there streams, as from an inextinguishable source, the undying energy and vitality of the Catholic Church. It will be readily seen then why, believing all this, Dr. Montessori regards this subject of such importance, and would make it so prominent a feature of the life in the Atrium”.
