Saint Montfort's Life in the Family

Louis-Marie Grignion was born in Montfort-sur-meu on January 31, 1673. He was baptized the following day at St. Mary's Parish Church. John. He was the second son of 18 children (8 sons and 10 daughters). His father named Jean-Baptiste Grignion (1647-1716) was a lawyer who was tough and temperamental. His mother named Jeanne Robert de la Viseule (1649-1718) was a devout, gentle, and patient person. His mother is the daughter of the mayor of Rennes.

Louis-Marie is the eldest child. This family adheres to a patriarchal system and was raised with strict discipline and piety to God. Of the eight sons, four of them died when they were young, three became priests, and one married. The two of Montfort’s sisters became nuns. The third daughter died as a member of the Order of St. Francis. A few days after his baptism, Montfort was entrusted to the wife of a kind farmer in La Bchelleraie, “Mother Andre” who is a good Catholic. And this servant of God, Louis, has loved and thanked him all his life. A cross had been staked in the place of his former home. This reminds people that this place was once sanctified by a saint. Life in the village is very harsh but full of peace and joy. Memories of the forests and serene fields will deeply imprint on this boy's mystical character.

After becoming a strong child, Mother Andre returns Louis-Marie to her father's house. Mrs. Grignion was surprised to see Louis-Marie so quiet beside her, while repeating the prayers her nanny had taught her. But the family did not stay in Montfort for long. Due to economic difficulties, Jean-Baptiste Grignion left the city and moved to Bois Marguer, a house in the village of Iffendic, four kilometers from the city. With his devout mother, Louis-Marie attended church in Iffendic. In front of the altar he prayed long and fervently. Together with the villagers, he attends Sunday mass and lets the Word of God encourage him in an ineffable way. Coming home from church, he often repeated almost literally the sermon or Catechism lesson he had heard. He must have often, alone or with other children, passed through the narrow winding roads of the village. In preparation for his First Communion he listened eagerly to his parish priests and received from them the first lessons which added to the basic knowledge he had learned at home. Like Jesus in the temple, he amazed his teachers with his obedience, intelligence, and effort. Then the teachers stated that he had never made it difficult for them. All tasks are done sincerely and never have to be forced. There was so much grace in his soul at that time.

Life of Saint Montfort During Education
At the age of 12 years St. Montfort became a strong and fast-growing young man with great intellectual talents. Near his house in the City of Rennes there is a school called St. Thomas Beckett. This school is run by the Jesuits. He was very close to a professor who taught literature, namely Fr. Camus. During school Montfort did not leave a life of prayer and work and therefore had no interest in going to places of entertainment. He uses his time to study and complete homework. Before going to school and after school, he always offered himself to Our Lady. He participated in the activities of the Brotherhood of St. Mary is revered in the Jesuit schools. Such a devotional life makes him brave to oppose all conversations and attitudes that are contrary to good manners and healthy education. Because of this attitude, he is highly respected by his friends and becomes a role model. When he returned home he became a “teacher” for his younger siblings. He taught his younger siblings to read and write and the catechism.

Become a Priest
Selama studi Santo Montfort mengasimilasi dengan baik ajaran imam suci yang mengajar maupun yang dengan cara tertentu terkait dengan Kolose tempat ia sekolah. Terutama keempat orang imam ini: P. Philipe Descartes, P. Prevost, Francois Gilbert dan Julien Bellier. Dari relasi dengan keempat tokoh ini tumbuh dalam diri Montfort tiga hal yang kemudian akan menandai seluruh hidupnya: pertama, kasih dan kepedulian terhadap orang miskin dan sakit; kedua, kasih dan devosi yang hangat kepada bunda Maria; ketiga, kasih dan gairah untuk karya misi. Dalam pencarian spiritual selama masa-masa studi di Rennes ini, ia lalu tiba pada keputusan untuk menjadi imam. Inilah yang dirasakannya sebagai panggilan hidupnya yang pasti. Maka setelah selesai studinya di Rennes, pada usia 20 tahun (1692) ia berangkat ke Paris untuk memasuki Seminari Tinggi St. Sulpice.

From 1692 to 1700 Montfort was a student at the Seminary Sant-Sulpice, a high seminary for the education of priests founded by Jean-Jacques Olier in 1642. The seminary is divided into the large Saint Sulpice housing the children of nobles and the small Saint Sulpice housing the seminaries of the small and poor. Montfort entered the small Saint Sulpice Seminary. During in this community, to earn extra for his life in the seminary, Montfort was begging in the streets of Paris, besides occasionally guarding the many bodies that filled morgues in Parisian shelters. In addition, while at the seminary, he was assigned by his spiritual director to: teach the catechism to young and poor people in Saint-Germain, become a seminary librarian, and witness events at the St. Sulpice Parish Church. For several years he attended Sorbonne University. Working as a librarian allowed him to read both Marian books, Pneumatology, Christology-Trinitarian and Ecclesiology, the opinions of the Church Fathers, and Church Doctors. The results of the readings are summarized in the Notebook. Finally, after eight years of study at Saint Sulpice, Montfort has ordained a priest on June 5, 1700.

From the very beginning of his work Saint Montfort had a desire to create a group of priests who served under the banner and protection of the Blessed Virgin Mary. This small group would later be called the Society of Mary.

The life of Saint Montfort is unique and is full of tension between holiness and the challenge of the sequence of life that his chosen.
