Ant. 1:In the company of angels, I will sing Psalms to you, O God.
1 O Lord our lord, *
how glorious is your name in all the world!
2 Your majesty above the heavens is praised *
out of the mouths of babes at the breast.
3 You have founded a stronghold against your foes, *
that you might still the enemy and the avenger.
4 When I consider your heavens, the work of your fingers, *
the moon and the stars that you have ordained,
5 What is man, that you should be mindful of him; *
the son of man, that you should seek him out?
6 You have made him little lower than the angels *
and crown him with glory and honour.
7 You have given him dominion over the works of your hands *
and put all things under his feet,
8 All sheep and oxen, *
even the wild beasts of the field,
9 The birds of the air, the fish of the sea *
and whatsoever moves in the paths of the sea.
10 O Lord our lord, *
how glorious is your name in all the world!

Psalm 138
Confitebor tibi
1 I will give you thanks, O Lord, with my whole heart*
  even before the gods will I sing your praises.
2 I will bow down toward your holy temple
  and give thanks to your name*
  because of your faithfulness and your loving-kindness,
  for you have made your name and your word supreme over all things.
3 At a time when I called to you, you gave me answer*
  and put new strength within my soul.
4 All the kings of the earth shall praise you, O Lord*
  for they have heard the words of your mouth;
5 And they shall sing of the ways of the Lord*
  that the glory of the Lord is great.
6 For though the Lord is exalted, he looks upon the lowly*
  but he humbles the proud from afar.
7 Though I walk in the midst of danger,
  yet will you preserve my life*
  you will stretch out your hand against the fury of my enemies,
  and your right hand shall save me.
8 The Lord will complete his purpose for me*
  your loving-kindness, O Lord, endures for ever;
  do not forsake the work of your own hands.

Ant. 3:
All the angels of heaven praise you, O Lord, and with one voice they say: To you we owe our hymn of praise O God.
Psalm 148
Laudate Domine
1 Alleluia.
Praise the Lord from the heavens; *
praise him in the heights.
2 Praise him, all you his angels; *
praise him, all his host.
3 Praise him, sun and moon; *
praise him, all you stars of light.
4 Praise him, heaven of heavens, *
and you waters above the heavens.
5 Let them praise the name of the Lord, *
for he commanded and they were created.
6 He made them fast for ever and ever; *
he gave them a law which shall not pass away.
7 Praise the Lord from the earth, *
you sea monsters and all deeps;
8 Fire and hail, snow and mist, *
tempestuous wind, fulfilling his word;
9 Mountains and all hills, *
fruit trees and all cedars;
10 Wild beasts and all cattle, *
creeping things and birds on the wing;
11 Kings of the earth and all peoples, *
princes and all rulers of the world;
12 Young men and women,
old and young together; *
let them praise the name of the Lord.
13 For his name only is exalted, *
his splendour above earth and heaven.
14 He has raised up the horn of his people
and praise for all his faithful servants, *
the children of Israel, a people who are near him.
Alleluia.
Then the LORD answered Job out of the whirlwind: "Who is this that darkens counsel by words without knowledge? Gird up your loins like a man, I will question you, and you shall declare to me.
"Where were you when I laid the foundation of the earth? Tell me, if you have understanding. Who determined its measurements--surely you know! Or who stretched the line upon it? On what were its bases sunk, or who laid its cornerstone when the morning stars sang together and all the heavenly beings shouted for joy?
Canticle
Te Deum Laudamus
God, we praise you; Lord, we proclaim you!
You, the Father, the eternal
all the earth venerates you.
All the angels, all the heavens, every power
The cherubim, the seraphim
unceasingly, they cry:
"Holy, Holy, Holy, Lord God of Hosts:
heaven and earth are full of the majesty of your glory!"
The glorious choir of Apostles
The noble ranks of prophets
The shining army of martyrs
all praise you.
Throughout the world your holy Church proclaims you.
Father of immeasurable majesty,
True Son, only-begotten, worthy of worship,
Holy Spirit, our Advocate.
You, Christ:
You are the king of glory.
You are the Father's eternal Son.
You, to free mankind, did not disdain a Virgin's womb.
You defeated the sharp spear of Death, and opened the kingdom of heaven to those who believe in you.
You sit at God's right hand, in the glory of the Father.
You will come, so we believe, as our Judge.
And so we ask of you: give help to your servants, whom you set free at the price of your precious blood.
Number them among your chosen ones in eternal glory.
Bring your people to safety, Lord, and bless those who are your inheritance.
Rule them and lift them high for ever.
Day by day we bless you, Lord: we praise you for ever and for ever.
Of your goodness, Lord, keep us without sin for today.
Have mercy on us, Lord, have mercy on us.
Let your pity, Lord, be upon us, as much as we trust in you.
In you, Lord, I trust: let me never be put to shame.
Glory be to the Father and to the Son and to the Holy Spirit,
as it was in the beginning, is now, and ever shall be,
world without end.
Amen.
Second Reading
Hebrews 1:1-14
Long ago God spoke to our ancestors in many and various ways by the prophets, but in these last days he has spoken to us by a Son, whom he appointed heir of all things, through whom he also created the worlds. He is the reflection of God's glory and the exact imprint of God's very being, and he sustains all things by his powerful word. When he had made purification for sins, he sat down at the right hand of the Majesty on high,
having become as much superior to angels as the name he has inherited is more excellent than theirs. For to which of the angels did God ever say, 'You are my Son; today I have begotten you'? Or again, 'I will be his Father, and he will be my Son'? And again, when he brings the firstborn into the world, he says, 'Let all God's angels worship him.' Of the angels he says, 'He makes his angels winds, and his servants flames of fire.' But of the Son he says, 'Your throne, O God, is forever and ever, and the righteous scepter is the scepter of your kingdom. You have loved righteousness and hated wickedness; therefore God, your God, has anointed you with the oil of gladness beyond your companions.' And, 'In the beginning, Lord, you founded the earth, and the heavens are the work of your hands; they will perish, but you remain; they will all wear out like clothing; like a cloak you will roll them up, and like clothing they will be changed. But you are the same, and your years will never end.' But to which of the angels has he ever said, 'Sit at my right hand until I make your enemies a footstool for your feet'? Are not all angels spirits in the divine service, sent to serve for the sake of those who are to inherit salvation?
