From “True Devotion” of St. Louis Grignion de Montfort
It is with a particular joy that my heart has dictated what I have just written, in order to show that the divine Mary has been up to this time unknown, and that this is one of the reasons that Jesus Christ is not known as He ought to be. If, then, as is certain, the kingdom of Jesus Christ is to come into the world, it will be but a necessary consequence of the knowledge of the kingdom of the most holy Virgin Mary, who brought Him into the world the first time, and will make His second advent full of splendour.
My heart has dictated with special joy all that I have written to show that Mary has been unknown up till now, and that that is one of the reasons why Jesus Christ is not known as he should be. If then, as is certain, the knowledge and the kingdom of Jesus Christ must come into the world, it can only be as a necessary consequence of the knowledge and reign of Mary. She who first gave him to the world will establish his kingdom in the world.
