“All true children of God have God for their father and Mary for their mother; anyone who does not have Mary for his mother, does not have God for his father.
“Mary received from God a far-reaching dominion over the souls of the elect. Otherwise she could not make her dwelling-place in them as God the Father has ordered her to do, and she could not conceive them, nourish them, and bring them forth to eternal life as their mother. She could not have them for her inheritance and her possession and form them in Jesus and Jesus in them. She could not implant in their heart the roots of her virtues, nor be the inseparable associate of the Holy Spirit in all these works of grace. None of these things, I repeat, could she do unless she had received from the Almighty rights and authority over their souls. For God, having given her power over his only-begotten and natural Son, also gave her power over his adopted children – not only in what concerns their body – which would be of little account – but also in what concerns their soul.”
–St. Louis de Montfort, True Devotion to Mary
