“Mary’s power over all demons will shine in a particular way in the end times, when Satan will undermine her heel, that is, her poor slaves and humble children whom she will raise up to wage war against him. These will be small and poor according to the world, as low to all as the heel, trampled and abused as the heel is in comparison to the other limbs of the body. In exchange they will be rich in divine grace, which Mary will communicate to them in abundance; great and elevated in holiness before God; superior to any other creature because of their ardent zeal; and so strongly supported by divine help, that with the humility of their heel, united with Mary, they will crush the head of the devil and make Jesus Christ triumph”.
