"Mary not only preserved and meditated on the events of Bethlehem and the facts which took place in Jerusalem in the Temple of the Lord, but sharing as she did the thoughts and the secret wishes of Christ she may be said to have lived the very life of her Son. Hence nobody ever knew Christ so profoundly as she did, and nobody can ever be more competent as a guide and teacher of the knowledge of Christ."

- Pope Pius X, Ad Diem Illium Laetissimum
