Collect

    O God, who hast willed that Thy Word should take flesh, at the message of an angel, in the womb of the blessed Virgin Mary, grant to us Thy suppliants, that we who believe her to be truly the Mother of God may be helped by her intercession with Thee. Through the same our Lord.

Epistle: Isaias vii. 10-15

    Lesson from the book of Isaias. In those days, the Lord spoke unto Achaz, saying: Ask thee a sign of the Lord thy God, either unto the depth of hell, or the height above. And Achaz said: I will not ask, and I will not tempt the Lord. And He said: Hear ye therefore, O house of David: Is it a small thing for you to be grievous to men, that you are grievous to My God also? Therefore, the Lord Himself shall give you a sign. Behold a virgin shall conceive and bear a son, and his name shall be called Emmanuel. He shall eat butter and honey, that he may know to refuse the evil, and to choose the good.

Gradual: Psalm xxiii. 7, 3-4

    Lift up your gates, O ye princes: and be ye lifted up, O eternal gates: and the King of Glory shall enter in. ℣. Who shall ascend into the mountain of the Lord, or who shall stand in His holy place? The innocent in hands and the clean of heart.

Alleluia: Luke i. 28

    Alleluia, alleluia. ℣. Hail, Mary, full of grace, the Lord is with thee: blessed art thou among women. Alleluia.

Gospel: Luke i. 26-38

    + Continuation of the holy Gospel according to the holy Apostle Luke. At that time, the angel Gabriel was sent from God into a city of Galilee, called Nazareth, to a virgin espoused to a man whose name was Joseph, of the house of David: and the virgin's name was Mary. And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women. Who having heard, was troubled at his saying and thought with herself what manner of salutation this should be. And the angel said to her: Fear not, Mary, for thou hast found grace with God. Behold thou shalt conceive in thy womb and shalt bring forth a Son: and thou shalt call His name Jesus. He shall be great and shall be called the Son of the Most High, and the Lord God shall give unto Him the throne of David his father: and he shall reign in the house of Jacob for ever, and of his kingdom there shall be no end. And Mary said to the angel: How shall this be done, because I know not man? And the angel answering, said to her: The Holy Ghost shall come upon thee and the power of the Most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God. And behold thy cousin Elizabeth, she also hath conceived a son in her old age: and this is the sixth month with her that is called barren; because no word shall be impossible with God. And Mary said: Behold the handmaid of the Lord, be it done to me according to thy word.

Offertory: Luke i. 28, 42

    Hail, Mary, full of grace, the Lord is with thee: blessed art thou among women and blessed is the fruit of thy womb.
