Epistle: Daniel ix. 21-26

    Lesson from the book of Daniel. In those days behold the man Gabriel, whom I had seen in the vision at the beginning, flying swiftly, touched me at the time of the evening sacrifice. And he instructed me and spoke to me and said: O Daniel, I am now come forth to teach thee, that thou mightest understand. From the beginning of thy prayers the word came forth: and I am come to show it to thee, because thou art a man of desires. Therefore, do thou mark the word and understand the vision. Seventy weeks are shortened upon thy people and upon thy holy city, that transgression may be finished and sin may have an end and iniquity may be abolished and everlasting justice may be brought and vision and prophecy may be fulfilled and the Saint of saints may be anointed. Know thou therefore and take notice: that from the going forth of the world to build up Jerusalem again, unto Christ the Prince. there shall be seven weeks and sixty-two weeks: and the street shall be built again, and the walls in straitness of times. And after sixty-two weeks Christ shall be slain: and the people that shall deny Him shall not be His. And a people, with their leader that shall come, shall destroy the city and the sanctuary: and the end thereof shall be waste, and after the end of the war the appointed desolation.

Gradual: Psalms cii. 20, 1

    Bless the Lord, all ye His angels, you that are mighty in strength and execute His words. ℣. Bless the Lord, O my soul, and let all that is within me bless His holy name.

Tract: Luke i. 28, 42, 31, 35

    Hail, Mary, full of grace, the Lord is with thee. ℣. Blessed art thou among women, and blessed is the fruit of thy womb. ℣. Behold thou shalt conceive and shalt bring forth a son, and thou shalt call his name Emmanuel. ℣. 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.

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: Apocalypse viii. 3, 4

    An angel stood near the altar of the temple, having a golden censer in his hand: and there was given to Him much incense, and the smoke of the perfume ascended before God.

Last Gospel of the Feria:

Gospel: John vii. 1-13

    + The continuation of the holy Gospel according to St. John. At that time Jesus walked in Galilee, for He would not walk in Judea, because the Jews sought to kill Him. Now the Jews' feast of Tabernacles was at hand. And His brethren said to Him: Pass from hence and go into Judea, that Thy disciples also may see Thy works which Thou dost. For there is no man that doth any thing in secret, and he himself seeketh to be known openly: if Thou do these things, manifest Thyself to the world. For neither did His brethren believe in Him. Then Jesus said to them: My time is not yet come: but your time is always ready. The world cannot hate you: but Me it hateth, because I give testimony of it, that the works thereof are evil. Go you up to this festival day, but I go not up to this festival day: because My time is not accomplished. When He had said these things, He Himself stayed in Galilee. But after His brethren were gone up, then He also went up to the feast not openly, but as it were in secret. The Jews therefore sought Him on the festival day, and said: Where is He? And there was much murmuring among the multitude concerning Him. For some said: He is a good man. And others said: No, but He seduceth the people. Yet no man spoke openly of Him, for fear of the Jews.
