Life
 (1673-1716)
 

In December 1996, Pope John Paul II authorized the addition to the universal calendar of the Church, the April 28th feast of St. Louis-Mary of Montfort. A word of explanation. When saints are canonized, they are assigned a feast day, normally the date of their death; but to avoid overcrowding the liturgical calendar of the Latin Rite, the observance of their festivals is restricted to certain groups or localities. Those listed in the worldwide calendar are saints considered to be persons of worldwide significance. Why was this French priest honored as a major saint fifty years after his canonization? Let us see who he was and what he achieved.

Louis Grignion was born January 31, 1673, at Montfort-la-Canne, in French Brittany, eldest of the eight children of John Baptist Grignion, a man of modest means. Louis early developed a deep, trusting devotion to the Blessed Virgin. At confirmation he took her name and became simply “Louis-Mary de Montfort.” Educated at Rennes by the Jesuits, he felt called to the priesthood, for which he studied in Paris, first at the Sorbonne, then at the Seminary of St. Sulpice. He was ordained a priest in 1700, and enrolled in the Third Order of the Dominicans ten years later. Abbé Louis-Mary doubtless joined the Dominican Third Order because of its connection with the Rosary, his favorite devotion. He had become acquainted with the extensive literature of the French School of spirituality and had read practically every available book on Mary.

His first assignment after ordination was to a chaplaincy in a hospital for the poor at Poitiers. The young priest quickly showed talents as an organizer. Finding the management of the hospital disorderly, he reorganized it. He also gathered from among its female staff and residents, the nucleus of a nursing religious order, the Daughters of Wisdom (1703), which is still functioning internationally. But the improvements he made were not welcomed by the hospital, so he had to resign his post. He turned then to preaching popular missions to the vicinity’s poor; but his bishop, egged on by his enemies, forbade him to preach anymore within the diocese. Undismayed, Father Grignion walked to Rome on foot to seek missionary faculties from Pope Clement XI. The Pope received him graciously and sent him back to France with the title of “missionary apostolic.” Returning to his native Brittany, he spent the rest of his life there giving parish missions.

Even in his homeland, however, clerical critics arose who hampered his work. Some of these were imbued with a Jansenistic attitude: harsh, rigorous men who favored heavy penances and frowned on frequent Communion. These were “false prophets,” and deserved to be countered. Other critics, however, did not care for the young priest’s dramatic pulpit methods. But the people to whom he preached loved to listen to him for just that reason. At Rochelle, a Calvinist stronghold, he reconciled numerous French Protestants.

Louis-Mary laid special stress on the Rosary. He could even join a crowd of men singing obscene songs and persuade them to kneel down and pray the Rosary. The strong leader of an effective re-evangelization, St. Louis in 1705 founded another religious order, the missionaries of the Company of Mary (the Montfort Fathers) to continue the work begun. But the founder himself died a decade later, aged only 43.

Grignion had written several spiritual books during his life. Only in 1842 was the manuscript of his chief work discovered and published, to become one of history’s most influential works. True Devotion to the Blessed Virgin argued that since we are called on to become like Jesus, the best method would be to consecrate ourselves to Mary, the one perfect Christian, entrusting to her the whole task of our sanctification. Pope John Paul II illustrates well the popularity of his devotion and its effectiveness. His papal motto “Totus Tuus” (“Totally thine”) was intended to be a statement of his personal acceptance of Montfort’s commitment to Mary. Also, in 1917, Mary, appearing at Fatima, asked that all be consecrated to her Immaculate Heart. In 1973 the Marian Movement of Priests began to urge this practice around the world, with the subsequent backing of the present pope. Complete self-entrustment to Our Lady has thus become a powerful contemporary apostolate. Its 18th-century promoter certainly deserves to be recognized in the universal calendar of the Church. Why not join St. Louis-Mary in consecrating ourselves to Mary the Mother of God and our Mother. --Father Robert F. McNamara

Scripture. Corinthians 1:18-25
 
Brothers and sisters: The message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. For it is written: I will destroy the wisdom of the wise, and the learning of the learned I will set aside. Where is the wise one? Where is the scribe? Where is the debater of this age? Has not God made the wisdom of the world foolish? For since in the wisdom of God the world did not come to know God through wisdom, it was the will of God through the foolishness of the proclamation to save those who have faith. For Jews demand signs and Greeks look for wisdom, but we proclaim Christ crucified, a stumbling block to Jews and foolishness to Gentiles, but to those who are called, Jews and Greeks alike, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than human wisdom, and the weakness of God is stronger than human strength. 
 

Writings

(Year A). Good and devout souls, who walk in the light of the Holy Spirit, I do not think you will mind my giving you this little mystical rose tree which comes straight from heaven and which is to be planted in the garden of your soul. It cannot possibly harm the sweet-smelling flowers of your contemplations; for it is a heavenly tree and its scent is very pleasant. It will not in the least interfere with your carefully planned flower-beds; for, being itself all pure and well-ordered, it inclines all to order and purity. If it is carefully watered and properly attended to every day, it will grow to such a marvellous height, and its branches will have such a wide span that, far from hindering your other devotions, it will maintain and perfect them. Of course, you understand what I mean, since you are spiritually minded; this mystical rose tree is Jesus and Mary in life, death and eternity. Its green leaves are the Joyful Mysteries, the thorns the Sorrowful ones, and the flowers the Glorious Mysteries of Jesus and Mary. The buds are the childhood of Jesus and Mary, and the open blooms show us both of them in their sufferings, and the full-blown roses symbolize Jesus and Mary in their triumph and glory. A rose delights us because of its beauty: so here we have Jesus and Mary in the Joyful Mysteries. Its thorns are sharp, and they prick, which makes us think of them in the Sorrowful Mysteries, and last of all, its perfume is so sweet that everyone loves it, and this fragrance symbolizes their Glorious Mysteries. So please do not scorn this beautiful and heavenly tree, but plant it with your own hands in the garden of your soul, by making the resolution to say your Rosary every day. By saying it daily and by doing good works you will be tending your tree, watering it, hoeing the earth around it. Eventually you will see that this little seed which I have given you, and which seems so small now, will grow into a tree so great that the birds of heaven, that is, predestinate and contemplative souls, will dwell in it and make their nests there. Its shade will shelter them from the scorching heat of the sun and its height will keep them safe from the wild beasts on the ground. And best of all, they will feed upon the tree's fruit, which is none other than our adorable Jesus, to whom be honour and glory forever and ever. Amen. God Alone (The Secret of the Rosary)

God of eternal wisdom,
you made your priest Louis Marie
an outstanding witness and teacher
of total dedication to Christ your Son
through the hands of the blessed Mother.
Grant that we may follow that same spiritual path
and extend your kingdom on earth.
We ask this through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
God for ever and ever. Amen. (ICEL; 1998)
