The Annunciation is from The Gospel of Luke 1:26–38. It is also known as the Annunciation to the Blessed Virgin Mary and the Annuciation of the Lord. It is the announcement made by the Archangel Gabriel to the Blessed Virgin Mary that she had been chosen by Almighty God to conceive a son by the power of the Holy Spirit and that He would be called Jesus.
26 And in the sixth month, the angel Gabriel was sent from God unto a city of Galilee, named Nazareth, 27 To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary. 28 And the angel came in unto her, and said, Hail, thou that art highly favored, the Lord is with thee: blessed art thou among women. 29 And when she saw him, she was troubled at his saying, and cast in her mind what manner of salutation this should be. 30 And the angel said unto her, Fear not, Mary: for thou hast found favor with God. 31 And, behold, thou shalt conceive in thy womb and bring forth a son, and shalt call his name Jesus. 32 He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: 33 And he shall reign over the house of Jacob forever; and of his kingdom, there shall be no end. 34 Then said Mary unto the angel, How shall this be, seeing I know not a man? 35 And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God. 36 And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. 37 For with God nothing shall be impossible. 38 And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.
The Blessed Virgin Mary hears to the announcement from Archangel Gabriel and consents with the words, “I am the handmaid of the Lord; be it done to me according to thy word.”
The Annunciation is a prophetic revelation of the Incarnation of Our Precious Lord and His redemption of mankind. It is the first of the Joyful Mysteries of the Holy Rosary.
