No one has penetrated the mystery of Christ except the Virgin Mary

"It seems to me that no one has penetrated the depths of the mystery of Christ except the Virgin Mary. Saint Paul often speaks of the "understanding" that was given to him, and yet, how dim all the saints remain, when we look at the clarity of the Virgin! She is indescribable! 

The secret she kept and replayed in her heart, no language has been able to reveal it, and no pen has been able to translate it. This Mother of grace will form my soul, so that her little child will be a living, striking image of her first-born, the Son of the Eternal, the one who was the perfect praise of his Father's glory." 

Sister Elizabeth of the Trinity (1880-1906)
