Solemnity of the Blessed Virgin Mary, the Mother of God
What Lucifer has lost by pride, Mary has gained by humanity. What Eve has damned and lost by disobedience, Mary has saved by obedience. Eve, in obeying the serpent, has destroyed all her children together with herself, and has delivered them to him; Mary, in being perfectly faithful to God, has saved all her children and servants together with herself, and has consecrated them to His Majesty.
