Montfort calls for a total consecration to Jesus Christ, the Eternal and Incarnate Wisdom, through the hands of Mary. This practice of Christian devotion is at the heart of the response which St. Louis Marie de Montfort recommends when we consider the love shown to mankind by God. It has also been variously called "The Holy Slavery" and "True Devotion" (from the name of the book, Treatise on True Devotion to the Blessed Virgin, in which St. Louis Marie describes it most thoroughly) - but it should be noted that when he speaks of "true" devotion, he is not picking out just one form of devotion, but intends to speak of "genuine" devotion in its many forms.
We find several descriptions of this practice in various books written by St. Louis Marie, for example:
From these quotations, certain things immediately stand out:
However, it is not enough to take a simple description of this practice. St. Louis Marie himself spent much time and effort to prepare people's minds for it, and to draw out its consequences and its benefits. And he recognised that different people would have different reactions to it, and would put it into practice at different levels:
"As this devotion essentially consists in a state of soul, it will not be understood in the same way by everyone. Some - the great majority - will stop short at the threshold and go no further. Others - not many - will take but one step into its interior. Who will take a second step? Who will take a third? Finally who will remain in it permanently? Only the one to whom the Spirit of Jesus reveals the secret. The Holy Spirit himself will lead this faithful soul from strength to strength, from grace to grace, from light to light, until at length he attains transformation into Jesus in the fullness of his age on earth and of his glory in heaven." (Treatise on True Devotion to the Blessed Virgin, 119)
