Mary, who was empty of all egotism, free from all sin, was as pure as the glass of a very clean window that has no other function than to admit the light of the sun. If we rejoice in that light, we implicitly praise the cleanness of the window. And, of course, it might be argued that in such a case we might well forget the window altogether. This is true. And yet the Son of God, in emptying himself of his majestic power, having become a child, abandoning himself in complete dependence to the loving care of a human mother, in a certain sense draws our attention once again to her.
The Light has wished to remind us of the window, because he is grateful to her and because he has an infinitely tender and personal love for her. If he asks us to share this love, it is certainly a great grace and a privilege, and one of the most important aspects of this privilege is that it enables us, to some extent, to appreciate the mystery of God's great love and respect for his creatures."
