Why Marian consecration? Here's why...

from True Devotion:

Our Blessed Lady, in her immense love for us, is eager to receive into her virginal hands the gift of our actions, imparting to them a marvelous beauty and splendour, and presenting them herself to Jesus most willingly. More glory is given to our Lord in this way than when we make our offering with our own guilty hands.

 

From True Devotion:

201. Here now are the services which the Virgin Mary, as the best of all mothers, lovingly renders to those loyal servants who have given themselves entirely to her in the manner I have described and following the figurative meaning of the story of Jacob and Rebecca.

1. She loves them.
"I love those who love me." She loves them:

1. Because she is truly their Mother. What mother does not love her child, the fruit of her womb?
2. She loves them in gratitude for the active love they show to her, their beloved Mother.
3. She loves them because they are loved by God and destined for heaven. "Jacob I loved, but Esau I hated."
4. She loves them because they have consecrated themselves entirely to her and belong to her portion, her inheritance. "In Israel receive your inheritance."

 

The saint for today, St. Teresa Benedicta of the Cross (Edith Stein) wrote this about our relationship to Our Lady:

"And just as the heart sustains the other organs of the woman's body and makes it possible for them to function, so we may genuinely believe there is just such a collaboration of Mary with every woman wherever that woman is fulfilling her vocation as woman; just so, there is a collaboration of Mary with us in all works of the Church.

But just as grace cannot achieve its work in souls unless they open themselves to it in free decision, so also Mary cannot function fully as a mother if people do not entrust themselves to her."

-Edith Stein, The Church, Woman, and Youth
