First Reading
GENESIS 3:9-15, 20

9But the LORD God called to the man, and said to him, "Where are you?" 10And he said, "I heard the sound of thee in the garden, and I was afraid, because I was naked; and I hid myself." 11He said, "Who told you that you were naked? Have you eaten of the tree of which I commanded you not to eat?" 12The man said, "The woman whom thou gavest to be with me, she gave me fruit of the tree, and I ate." 13Then the LORD God said to the woman, "What is this that you have done?" The woman said, "The serpent beguiled me, and I ate." 14The LORD God said to the serpent, "Because you have done this, cursed are you above all cattle, and above all wild animals; upon your belly you shall go, and dust you shall eat all the days of your life. 15I will put enmity between you and the woman, and between your seed and her seed; he shall bruise your head, and you shall bruise his heel." 20The man called his wife's name Eve, because she was the mother of all living.

Responsorial Psalm
PSALMS 98:1-4

1O sing to the LORD a new song, for he has done marvelous things! His right hand and his holy arm have gotten him victory. 2The LORD has made known his victory, he has revealed his vindication in the sight of the nations. 3He has remembered his steadfast love and faithfulness to the house of Israel. All the ends of the earth have seen the victory of our God. 4Make a joyful noise to the LORD, all the earth; break forth into joyous song and sing praises!

EPHESIANS 1:3-6, 11-12

3Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, 4even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. 5He destined us in love to be his sons through Jesus Christ, according to the purpose of his will, 6to the praise of his glorious grace which he freely bestowed on us in the Beloved. 11In him, according to the purpose of him who accomplishes all things according to the counsel of his will, 12we who first hoped in Christ have been destined and appointed to live for the praise of his glory.

Gospel
LUKE 1:26-38

26In the sixth month the angel Gabriel was sent from God to a city of Galilee named Nazareth, 27to a virgin betrothed to a man whose name was Joseph, of the house of David; and the virgin's name was Mary. 28And he came to her and said, "Hail, full of grace, the Lord is with you!" 29But she was greatly troubled at the saying, and considered in her mind what sort of greeting this might be. 30And the angel said to her, "Do not be afraid, Mary, for you have found favor with God. 31And behold, you will conceive in your womb and bear a son, and you shall call his name Jesus. 32He will be great, and will be called the Son of the Most High; and the Lord God will give to him the throne of his father David, 33and he will reign over the house of Jacob for ever; and of his kingdom there will be no end." 34And Mary said to the angel, "How shall this be, since I have no husband?" 35And the angel said to her, "The Holy Spirit will come upon you, and the power of the Most High will overshadow you; therefore the child to be born will be called holy, the Son of God. 36And behold, your kinswoman Elizabeth in her old age has also conceived a son; and this is the sixth month with her who was called barren. 37For with God nothing will be impossible." 38And Mary said, "Behold, I am the handmaid of the Lord; let it be to me according to your word." And the angel departed from her.
