PSALMODY

Ant. 1 Let God arise, let his enemies flee before him.

Psalm 68
The Lord’s triumphant entrance into his sanctuary
Ascending on high he led captivity captive, and gave gifts to men (Ephesians 4:10).

I

Let God arise, let his foes be scattered.
Let those who hate him flee before him.
As smoke is blown away so will they be blown away;
like wax that melts before the fire,
so the wicked shall perish at the presence of God.

But the just shall rejoice at the presence of God,
they shall exult and dance for joy.
O sing to the Lord, make music to his name;
make a highway for him who rides on the clouds.
Rejoice in the Lord, exult at his presence.

Father of the orphan, defender of the widow,
such is God in his holy place.
God gives the lonely a home to live in;
he leads the prisoners forth into freedom:
but rebels must dwell in a parched land.

When you went forth, O God,
at the head of your people,
when you marched across the desert,
the earth trembled: the heavens melted at the presence of God,
at the presence of God, Israel’s God.

You poured down, O God, a generous rain:
when your people were starved you gave them new life.
It was there that your people found a home,
prepared in your goodness, O God, for the poor.

Glory to the Father, and to the Son, and to the Holy Spirit:
— as it was in the beginning, is now, and will be for ever. Amen.

Ant. Let God arise, let his enemies flee before him.

Ant. 2 Our God is a saving God; he, the Lord, holds the keys of death.

II

The Lord gives the word to the bearers of good tidings:
“The Almighty has defeated a numberless army
and kings and armies are in flight, in flight
while you were at rest among the sheepfolds.”

At home the women already share the spoil.
They are covered with silver as the wings of a dove,
its feathers brilliant with shining gold
and jewels flashing like snow on Mount Zalmon.

The mountains of Bashan are mighty mountains;
high-ridged mountains are the mountains of Bashan.
Why look with envy, you high-ridged mountains,
at the mountain where God has chosen to dwell?
It is there that the Lord shall dwell for ever.

The chariots of God are thousands upon thousands.
The Lord has come from Sinai to the holy place.
You have gone up on high; you have taken captives,
receiving men in tribute, O God,
even those who rebel, into your dwelling, O Lord.

May the Lord be blessed day after day.
He bears our burdens, God our savior.
This God of ours is a God who saves.
The Lord our God holds the keys of death.
And God will smite the head of his foes,
the crown of those who persist in their sins.

The Lord said: “I will bring them back from Bashan;
I will bring them back from the depth of the sea.
Then your feet will tread in their blood
and the tongues of your dogs take their share of the foe.”

Glory to the Father, and to the Son, and to the Holy Spirit:
— as it was in the beginning, is now, and will be for ever. Amen.

Ant. Our God is a saving God; he, the Lord, holds the keys of death.

Ant. 3 Kingdoms of earth, sing praise to God, make music in honor of the Lord.

III

They see your solemn procession, O God,
the procession of my God, of my king, to the sanctuary:
the singers in the forefront, the musicians coming last,
between them, maidens sounding their timbrels.

“In festive gatherings, bless the Lord;
bless God, O you who are Israel’s sons.”
There is Benjamin, least of the tribes, at the head,
Judah’s princes, a mighty throng,
Zebulun’s princes, Naphtali’s princes.

Show forth, O God, show forth your might,
your might, O God, which you have shown for us.
For the sake of your temple high in Jerusalem
may kings come to you bringing their tribute.

Threaten the wild beast that dwells in the reeds,
the bands of the mighty and lords of the peoples.
Let them bow down offering silver.
Scatter the peoples who delight in war.
Princes will make their way from Egypt:
Ethiopia will stretch out her hands to God.

Kingdoms of the earth, sing to God, praise the Lord
who rides on the heavens, the ancient heavens.
He thunders his voice, his mighty voice.
Come, acknowledge the power of God.

His glory is on Israel; his might is in the skies.
God is to be feared in his holy place.
He is the Lord, Israel’s God.
He gives strength and power to his people.

Blessed be God!

Glory to the Father, and to the Son, and to the Holy Spirit:
— as it was in the beginning, is now, and will be for ever. Amen.

Psalm-prayer

Jesus Christ, King of the universe, you have given us joy in your holy meal. Help us to understand the significance of your death and to acknowledge you as the conqueror of death seated at the right hand of the Father.

Ant. Kingdoms of earth, sing praise to God, make music in honor of the Lord.

Sacred Silence (indicated by a bell)
A moment to reflect and receive in our hearts the full resonance of the voice of the Holy Spirit and to unite our personal prayer more closely with the word of God and public voice of the Church.

The Lord proclaims his word to Jacob,
— His laws and decrees to Israel.

READINGS

First reading
From the book of the prophet Isaiah
45:1-13
The salvation of Israel through Cyrus

Thus says the Lord to his anointed, Cyrus,
whose right hand I grasp,
Subduing nations before him,
and making kings run in his service,
Opening doors before him
and leaving the gates unbarred:
I will go before you
and level the mountains;
Bronze doors I will shatter,
and iron bars I will snap.
I will give you treasures out of the darkness,
and riches that have been hidden away,
That you may know that I am the Lord, the God of Israel,
who calls you by your name.

For the sake of Jacob, my servant,
of Israel my chosen one,
I have called you by your name,
giving you a title, though you knew me not.
I am the Lord and there is no other,
there is no God besides me.
It is I who arm you, though you know me not,
so that toward the rising and the setting of the sun
men may know that there is none besides me.
I am the Lord, there is no other;
I form the light, and create the darkness,
I make well-being and create woe;
I, the Lord, do all these things.

Let justice descend, O heavens, like dew from above,
like gentle rain let the skies drop it down.
Let the earth open and salvation bud forth;
let justice also spring up!
I, the Lord, have created this.

Woe to him who contends with his Maker;
a potsherd among potsherds of the earth!
Dare the clay say to its modeler, “What are you doing?”
or, “What you are making has no hands”?
Woe to him who asks a father, “What are you begetting?”
or a woman, “What are you giving birth to?”

Thus says the Lord,
the Holy One of Israel, his maker:
You question me about my children,
or prescribe the work of my hands for me!
It was I who made the earth
and created mankind upon it;
It was my hands that stretched out the heavens;
I gave the order to all their host.
It was I who stirred up one for the triumph of justice;
all his ways I make level.
He shall rebuild my city
and let my exiles go free
Without price or ransom,
says the Lord of hosts.

RESPONSORY Isaiah 45:8; see 16:1

Let the heavens drop down gentle showers,
let the clouds rain down the Just One,
— and let the earth bring forth a Savior.

Lord, send the Lamb, the ruler of the earth, from the
Rock in the desert to the mountain of the daughter of Zion.
— And let the earth bring forth a Savior.

Second reading
From a letter by Saint Leo the Great, pope
The mystery of our reconciliation with God

To speak of our Lord, the son of the Blessed Virgin Mary, as true and perfect man is of no value to us if we do not believe that he is descended from the line of ancestors set out in the Gospel.
Matthew’s gospel begins by setting out the genealogy of Jesus Christ, son of David, son of Abraham, and then traces his human descent by bringing his ancestral line down to his mother’s husband, Joseph. On the other hand, Luke traces his parentage backward step by step to the actual father of mankind, to show that both the first and the last Adam share the same nature.

No doubt the Son of God in his omnipotence could have taught and sanctified men by appearing to them in a semblance of human form as he did to the patriarchs and prophets, when for instance he engaged in a wrestling contest or entered into conversation with them, or when he accepted their hospitality and even ate the food they set before him. But these appearances were only types, signs that mysteriously foretold the coming of one who would take a true human nature from the stock of the patriarchs who had gone before him. No mere figure, then, fulfilled the mystery of our reconciliation with God, ordained from all eternity. The Holy Spirit had not yet come upon the Virgin nor had the power of the Most High overshadowed her, so that within her spotless womb Wisdom might build itself a house and the Word become flesh. The divine nature and the nature of a servant were to be united in one person so that the Creator of time might be born in time, and he through whom all things were made might be brought forth in their midst.

For unless the new man, by being made in the likeness of sinful humanity, had taken on himself the nature of our first parents, unless he had stooped to be one in substance with his mother while sharing the Father’s substance and, being alone free from sin, united our nature to his, the whole human race would still be held captive under the dominion of Satan. The Conqueror’s victory would have profited us nothing if the battle had been fought outside our human condition. But through this wonderful blending the mystery of new birth shone upon us, so that through the same Spirit by whom Christ was conceived and brought forth we too might be born again in a spiritual birth; and in consequence the evangelist declares the faithful to have been born not of blood, nor of the desire of the flesh, nor of the will of man, but of God.

RESPONSORY See Isaiah 11:10; Luke 1:32

Behold the root of Jesse will come down to save the people,
the nations will entreat him;
— and his name will be held in reverence.

The Lord God will give him the throne of David, his father,
and he will rule over the house of Jacob for ever.
— And his name will be held in reverence.

CONCLUDING PRAYER

O God, Creator and Redeemer of human nature,
who willed that your Word should take flesh
in an ever-virgin womb,
look with favor on our prayers,
that your Only Begotten Son,
having taken to himself our humanity,
may be pleased to grant us a share in his divinity.
Who lives and reigns with you in the unity of the Holy Spirit,
God, for ever and ever.
— Amen.

ACCLAMATION (at least in the communal celebration)

Let us praise the Lord.
— And give him thanks.
