Montfort was born in 1673 in
Montfort-sur-Meu, the eldest surviving child of eighteen born to Jean-Baptiste and Jeanne Robert Grignion. His father was a notary. Louis-Marie passed most of his infancy and early childhood in
Iffendic, a few kilometers from Montfort, where his father had bought a farm. At the age of 12, he entered the
Jesuit College of St Thomas Becket in
Rennes, where his uncle was a parish priest. At the end of his ordinary schooling, he began his studies of philosophy and theology, still at St Thomas in Rennes. Listening to the stories of a local priest, the Abbé Julien Bellier, about his life as an itinerant missionary, Montfort was inspired to preach missions among the very poor. Bellier was propagating among his students a
consecration and entrustment to Mary. Under the guidance of Bellier and other priests, de Montfort began to develop his strong devotion to the
Blessed Virgin Mary. where Montfort had earlier studied for the priesthood Through a benefactor, opportunity arose to go to Paris to study at the renowned Seminary of
Saint-Sulpice towards the end of 1693. When Montfort arrived in Paris, it was to find that his benefactor had not provided enough money for him, so he lodged in a succession of boarding houses, living among the very poor, in the meantime attending the Sorbonne University for lectures in theology. After less than two years, he became very ill and had to be admitted to hospital. He survived this, despite the blood letting that was common practice at that time. Leaving hospital, he was surprised to find his place had been kept open for him at the
Little Saint-Sulpice, which he entered in July 1695. This seminary had been founded by
Jean-Jacques Olier, one of the leading experts of what came to be known as the
French school of spirituality. One reason behind Montfort's showing such devotion to angels is that veneration of the pure spirits was an integral part of his training, and also of his culture. His college teachers, all Jesuits, were known for their zeal in propagating devotion to the angels. Montfort's seminary training under the Sulpicians brought him into contact with the thought of
Cardinal de Bérulle and Olier, both of whom had deep veneration for the angels. During the seventeenth and eighteenth centuries, manuals of piety and treatises on the pure spirits abounded. ==From priest to preacher==
