Saint Louis de Montfort was an 18th century French priest known for his devotion to Mary and teaching of total consecration to Jesus through Mary. He taught that the most perfect path to union with Christ was through total consecration, by which one gives all aspects of themselves to Jesus through handing themselves over to Mary. This devotion allows one to fulfill their baptismal vows and receive greater graces. Living consecration involves doing all actions first through, with, in and for Mary in order to do them more perfectly through, with, in and for Jesus.
