"The unique privilege of the Virgin Mary"

"The Blessed Virgin Mary’s unique privilege is to have been exempt from the original stain and to be the Mother of God. But even so, regarding this last point, Jesus told us: ‘He who does the will of my Father in heaven, he is my brother, my sister, my mother’ (Mt. 12, 50). 

On the other hand, we are happier than she is, because... she did not have a Blessed Virgin to love!... This is such an extra sweetness for us, and such a lesser sweetness for her!"
