First Reading: Isaiah 42:1-4, 6-7 or Isaiah 40:1-5, 9-11
Behold my servant, I will uphold him: my elect, my soul delighteth in him: I have given my spirit upon him, he shall bring forth judgment to the Gentiles. He shall not cry, nor have respect to person, neither shall his voice be heard abroad. The bruised reed he shall not break, and smoking flax he shall not quench: he shall bring forth judgment unto truth. He shall not be sad, nor troublesome, till he set judgment in the earth: and the islands shall wait for his law. (T)he Lord have called thee in justice, and taken thee by the hand, and preserved thee. And I have given thee for a covenant of the people, for a light of the Gentiles: That thou mightest open the eyes of the blind, and bring forth the prisoner out of prison, and them that sit in darkness out of the prison house.

Be comforted, be comforted, my people, saith your God. Speak ye to the heart of Jerusalem, and call to her: for her evil is come to an end, her iniquity is forgiven: she hath received of the hand of the Lord double for all her sins. The voice of one crying in the desert: Prepare ye the way of the Lord, make straight in the wilderness the paths of our God. Every valley shall be exalted, and every mountain and hill shall be made low, and the crooked shall become straight, and the rough ways plain. And the glory of the Lord shall be revealed, and all flesh together shall see, that the mouth of the Lord hath spoken. Get thee up upon a high mountain, thou that bringest good tidings to Sion: lift up thy voice with strength, thou that bringest good tidings to Jerusalem: lift it up, fear not. Say to the cities of Juda: Behold your God: Behold the Lord God shall come with strength, and his arm shall rule: Behold his reward is with him and his work is before him. He shall feed his flock like a shepherd: he shall gather together the lambs with his arm, and shall take them up in his bosom, and he himself shall carry them that are with young.

R. Bless the Lord, O my soul
V. O Lord my God, thou art exceedingly great. Thou hast put on praise and beauty:
And art clothed with light as with a garment. Who stretchest out the heaven like a pavilion:
V. Who coverest the higher rooms thereof with water. Who makest the clouds thy chariot: who walkest upon the wings of the winds.
Who makest thy angels spirits: and thy ministers a burning fire.
V. How great are thy works, O Lord? thou hast made all things in wisdom: the earth is filled with thy riches.
So is this great sea, which stretcheth wide its arms: there are creeping things without number: Creatures little and great.
V. All expect of thee that thou give them food in season.
What thou givest to them they shall gather up: when thou openest thy hand, they shall all be filled with good.
V. But if thou turnest away thy face, they shall be troubled: thou shalt take away their breath, and they shall fail, and shall return to their dust.
Thou shalt send forth thy spirit, and they shall be created: and thou shalt renew the face of the earth.
Second Reading: Acts 10:34-38 or Titus 2:11-14; 3:4-7
And Peter opening his mouth, said: In very deed I perceive, that God is not a respecter of persons. But in every nation, he that feareth him, and worketh justice, is acceptable to him. God sent the word to the children of Israel, preaching peace by Jesus Christ: (he is Lord of all.) You know the word which hath been published through all Judea: for it began from Galilee, after the baptism which John preached, Jesus of Nazareth: how God anointed him with the Holy Ghost, and with power, who went about doing good, and healing all that were oppressed by the devil, for God was with him.

For the grace of God our Saviour hath appeared to all men; Instructing us, that, denying ungodliness and worldly desires, we should live soberly, and justly, and godly in this world, Looking for the blessed hope and coming of the glory of the great God and our Saviour Jesus Christ, Who gave himself for us, that he might redeem us from all iniquity, and might cleanse to himself a people acceptable, a pursuer of good works. But when the goodness and kindness of God our Saviour appeared: Not by the works of justice, which we have done, but according to his mercy, he saved us, by the laver of regeneration, and renovation of the Holy Ghost; Whom he hath poured forth upon us abundantly, through Jesus Christ our Saviour: That, being justified by his grace, we may be heirs, according to hope of life everlasting.
Gospel Reading: Luke 3:15-16, 21-22
And as the people were of opinion, and all were thinking in their hearts of John, that perhaps he might be the Christ; John answered, saying unto all: I indeed baptize you with water; but there shall come one mightier than I, the latchet of whose shoes I am not worthy to loose: he shall baptize you with the Holy Ghost, and with fire: Now it came to pass, when all the people were baptized, that Jesus also being baptized and praying, heaven was opened; And the Holy Ghost descended in a bodily shape, as a dove upon him; and a voice came from heaven: Thou art my beloved Son; in thee I am well pleased.
