A Treatise on the True Devotion to the Blessed Virgin or True Devotion to Mary is considered the greatest book on the Blessed Virgin Mary ever written and has been recommended and practiced by eight Popes. This is the original ‘scrupulously faithful’ translation by Reverend Frederick William Faber, D. D.. The great Marian Pope, Blessed Pope John Paul II practiced this Devotion to Mary, in his Letter to the Montfort Fathers he says:

“A work destined to become a classic of Marian spirituality was published 160 years ago. St. Louis Marie Grignion de Montfort wrote the Treatise on True Devotion to the Blessed Virgin at the beginning of the 1700s, but the manuscript remained practically unknown for more than a century. When, almost by chance, it was at last discovered in 1842 and published in 1843, the work was an instant success, proving extraordinarily effective in spreading the “true devotion” to the Most Holy Virgin.”

“My motto; ‘Totus Tuus’ is inspired by the teaching of St. Louis Marie Grignion de Montfort. These two words express total belonging to Jesus through Mary: ‘Tuus totus ego sum, et omnia mea tua sunt,’ St Louis Marie wrote, and he translates his words: ‘I am all yours, and all that I have is yours, O most loving Jesus, through Mary, your most holy Mother’ (Treatise on True Devotion, n. 233). This Saint’s teaching has had a profound influence on the Marian devotion of many of the faithful and on my own life. It is a lived teaching of outstanding ascetic and mystical depth, expressed in a lively and passionate style that makes frequent use of images and symbols.”
