FIRST READING (Upon you the Lord shines, and over you appears his glory.)

A reading from the Book of the Prophet Isaiah (60:1-6)

Rise up in splendor, Jerusalem! Your light has come, the glory of the Lord shines upon you. See, darkness covers the earth, and thick clouds cover the peoples; but upon you the Lord shines, and over you appears his glory. Nations shall walk by your light, and kings by your shining radiance. Raise your eyes and look about; they all gather and come to you: your sons come from afar, and your daughters in the arms of their nurses.

Then you shall be radiant at what you see, your heart shall throb and overflow, for the riches of the sea shall be emptied out before you, the wealth of nations shall be brought to you. Caravans of camels shall fill you, dromedaries from Midian and Ephah; all from Sheba shall come bearing gold and frankincense, and proclaiming the praises of the Lord.—The Word of the Lord.

R. Thanks be to God.

RESPONSORIAL PSALM (19:2-3, 4-5)

R. The heavens declare the glory of God. (Ps 19:2)

The heavens declare the glory of God, and the firmament proclaims his handiwork. Day pours out the word to day; and night to night imparts knowledge. (R)

Not a word nor a discourse whose voice is not heard; through all the earth their voice resounds, and to the ends of the world, their message. (R)

SECOND READING (“I am the Alpha and the Omega,” says the Lord God.)

A reading from the Book of Revelation (1:3-8)

Blessed is the one who reads aloud and blessed are those who listen to this prophetic message and heed what is written in it, for the appointed time is near.

John, to the seven churches in Asia: grace to you and peace from him who is and who was and who is to come, and from the seven spirits before his throne, and from Jesus Christ, the faithful witness, the firstborn of the dead and ruler of the kings of the earth. To him who loves us and has freed us from our sins by his blood, who has made us into a kingdom, priests for his God and Father. To him be glory and power. Amen.

Behold, Jesus Christ is coming amid the clouds, and every eye will see him, even those who pierced him. All the peoples of the earth will lament him. Yes, Amen.

“I am the Alpha and the Omega,” says the Lord God, “the one who is and who was and who is to come, the almighty.”—The Word of the Lord.

R. Thanks be to God.

GOSPEL ACCLAMATION (Jn 3:16)

GOSPEL (As you sent me into the world, so I sent them into the world.)

A reading from the holy Gospel according to John (17:11b, 17-23)

Lifting up his eyes to heaven, Jesus prayed, saying: “Holy Father, keep them in your name that you have given me, so that they may be one just as we are one.

“Consecrate them in truth. Your word is truth. As you sent me into the world, so I sent them into the world. And I consecrate myself for them, so that they also may be consecrated in truth.

“I pray not only for these, but also for those who will believe in me through their word, so that they may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me. And I have given them the glory you gave me, so that they may be one, as we are one, I in them and you in me, that they may be brought to perfection as one, that the world may know that you sent me, and that you loved them even as you loved me.”—The Gospel of the Lord.

R. Praise to you, Lord Jesus Christ.
