PSALMODY

Ant. 1 Peter said: God has raised up and glorified this Jesus, whom you put to death.

Psalm 19A
Praise of the Lord, Creator of all
The dawn from on high shall break on us… to guide our feet into the way of peace (Luke 1:78, 79).

The heavens proclaim the glory of God
and the firmament shows forth the work of his hands.
Day unto day takes up the story
and night unto night makes known the message.

No speech, no word, no voice is heard
yet their span extends through all the earth,
their words to the utmost bounds of the world.

There he has placed a tent for the sun;
it comes forth like a bridegroom coming from his tent,
rejoices like a champion to run its course.

At the end of the sky is the rising of the sun;
to the furthest end of the sky is its course.
There is nothing concealed from its burning heat.

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. Peter said: God has raised up and glorified this Jesus, whom you put to death.

Ant. 2 The Lord has sent his angel to free me from Herod’s power.

Psalm 64
Prayer for help against enemies
This psalm commemorates most particularly our Lord’s passion (Saint Augustine).

Hear my voice, O God, as I complain,
guard my life from dread of the foe.
Hide me from the band of the wicked,
from the throng of those who do evil.

They sharpen their tongues like swords;
they aim bitter words like arrows
to shoot at the innocent from ambush,
shooting suddenly and recklessly.

They scheme their evil course;
they conspire to lay secret snares.
They say: “Who will see us?
Who can search out our crimes?”

He will search who searches the mind
and knows the depth of the heart.
God has shot them with his arrow
and dealt them sudden wounds.
Their own tongue has brought them to ruin
and all who see them mock.

Then will all men fear;
they will tell what God has done.
They will understand God’s deeds.
The just will rejoice in the Lord
and fly to him for refuge.
All the upright hearts will glory.

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. The Lord has sent his angel to free me from Herod’s power.

Ant. 3 Suddenly a bright cloud overshadowed them, and the Father’s voice was heard: This is my beloved Son.

Psalm 97
The glory of the Lord in his decrees for the world
This psalm foretells a world-wide salvation and that peoples of all nations will believe in Christ (St. Athanasius).

The Lord is king, let earth rejoice,
let all the coastlands be glad.
Cloud and darkness are his raiment;
his throne, justice and right.

A fire prepares his path;
it burns up his foes on every side.
His lightnings light up the world,
the earth trembles at the sight.

The mountains melt like wax
before the Lord of all the earth.
The skies proclaim his justice;
all peoples see his glory.

Let those who serve idols be ashamed,
those who boast of their worthless gods.
All you spirits, worship him.

Zion hears and is glad;
the people of Judah rejoice
because of your judgments, O Lord.

For you indeed are the Lord,
most high above all the earth,
exalted far above all spirits.
The Lord loves those who hate evil:
he guards the souls of his saints;
he sets them free from the wicked.

Light shines forth for the just
and joy for the upright of heart.
Rejoice, you just, in the Lord;
give glory to his holy name.

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. Suddenly a bright cloud overshadowed them, and the Father’s voice was heard: This is my beloved Son.

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.

Lord, to whom shall we go?
— You have the words of eternal life.

READINGS

First reading
From the Acts of the Apostles
11:1-18
Peter tells of the conversion of the Gentiles

All through Judea the apostles and the brothers heard that Gentiles, too, had accepted the word of God. As a result, when Peter went up to Jerusalem some among the circumcised took issue with him, saying, “You entered the house of uncircumcised men and ate with them.”

Peter then explained the whole affair to them step by step from the beginning: “I was at prayer in the city of Joppa when, in a trance, I saw a vision. An object like a big canvas came down; it was lowered down to me from the sky by its four corners. As I stared at it I could make out four-legged creatures of the earth, wild beasts and reptiles, and birds of the sky.

“I listened as a voice said to me, ‘Get up, Peter! Slaughter, then eat.’ I replied: ‘Not for a moment, sir! Nothing unclean or impure has ever entered my mouth!’ A second time the voice from the heavens spoke out: ‘What God has purified you are not to call unclean.’ This happened three times; then the canvas with everything in it was drawn up again into the sky.

“Immediately after that, the three men who had been sent to me from Caesarea came to the house where we were staying. The Spirit instructed me to accompany them without hesitation. These six brothers came along with me, and we entered the man’s house. He informed us that he had seen an angel standing in his house and that the angel had said: ‘Send someone to Joppa and fetch Simon, known also as Peter. In the light of what he will tell you, you shall be saved, and all your household.’

“As I began to address them the Holy Spirit came upon them, just as it had upon us at the beginning. Then I remembered what the Lord had said: ‘John baptized with water but you will be baptized with the Holy Spirit.’ If God was giving them the same gift he gave us when we first believed in the Lord Jesus Christ, who was I to interfere with him?”

When they heard this they stopped objecting, and instead began to glorify God in these words: “If this be so, then God has granted life-giving repentance even to the Gentiles.”

RESPONSORY Luke 22:32; Matthew 16:17b

I have prayed for you, Peter, that your faith may not fail;
— and when you have turned to me, you must strengthen the faith of your brothers.

Flesh and blood has not revealed this to you, but my Father in heaven.
— And when you have turned to me, you must strengthen the faith of your brothers.

Second reading
From a sermon by Saint Leo the Great, pope
The Church of Christ rises on the firm foundation of Peter’s faith

Out of the whole world one man, Peter, is chosen to preside at the calling of all nations, and to be set over all the apostles and all the fathers of the Church. Though there are in God’s people many shepherds, Peter is thus appointed to rule in his own person those whom Christ also rules as the original ruler. Beloved, how great and wonderful is this sharing of his power that God in his goodness has given to this man. Whatever Christ has willed to be shared in common by Peter and the other leaders of the Church, it is only through Peter that he has given to others what he has not refused to bestow on them.

The Lord now asks the apostles as a whole what men think of him. As long as they are recounting the uncertainty born of human ignorance, their reply is always the same.

But when he presses the disciples to say what they think themselves, the first to confess his faith in the Lord is the one who is first in rank among the apostles.

Peter says: You are the Christ, the Son of the living God. Jesus replies: Blessed are you, Simon Bar-Jona, for flesh and blood has not revealed it to you, but my Father who is in heaven. You are blessed, he means, because my Father has taught you. You have not been deceived by earthly opinion, but have been enlightened by inspiration from heaven. It was not flesh and blood that pointed me out to you, but the one whose only-begotten Son I am.

He continues: And I say to you. In other words, as my Father has revealed to you my godhead, so I in my turn make known to you your pre-eminence. You are Peter: though I am the inviolable rock, the cornerstone that makes both one, the foundation apart from which no one can lay any other, yet you also are a rock, for you are given solidity by my strength, so that which is my very own because of my power is common between us through your participation.

And upon this rock I will build my Church, and the gates of hell shall not prevail against it. On this strong foundation, he says, I will build an everlasting temple. The great height of my Church, which is to penetrate the heavens, shall rise on the firm foundation of this faith.

The gates of hell shall not silence this confession of faith; the chains of death shall not bind it. Its words are the words of life. As they lift up to heaven those who profess them, so they send down to hell those who contradict them.

Blessed Peter is therefore told: To you I will give the keys of the kingdom of heaven. Whatever you bind on earth is also bound in heaven. Whatever you loose on earth shall be loosed also in heaven.

The authority vested in this power passed also to the other apostles, and the institution established by this decree has been continued in all the leaders of the Church. But it is not without good reason that what is bestowed on all is entrusted to one. For Peter received it separately in trust because he is the prototype set before all the rulers of the Church.

RESPONSORY

Before I called you from the boat, I knew you, Simon Peter, and I have appointed you leader of my people.
— I have entrusted to you the keys of the kingdom of heaven.

Whatever you bind on earth will be held bound in heaven. Whatever you loose on earth will be held loosed in heaven.
— I have entrusted to you the keys of the kingdom of heaven.

TE DEUM

You are God: we praise you;
You are the Lord: we acclaim you;
You are the eternal Father:
All creation worships you.

To you all angels, all the powers of heaven,
Cherubim and Seraphim, sing in endless praise:
Holy, holy, holy, Lord, God of power and might,
heaven and earth are full of your glory.

The glorious company of apostles praise you.
The noble fellowship of prophets praise you.
The white-robed army of martyrs praise you.

Throughout the world the holy Church acclaims you:
Father, of majesty unbounded,
your true and only Son, worthy of all worship,
and the Holy Spirit, advocate and guide.

You, Christ, are the King of glory,
the eternal Son of the Father.

When you became man to set us free
you did not spurn the Virgin’s womb.

You overcame the sting of death,
and opened the kingdom of heaven to all believers.

You are seated at God’s right hand in glory.
We believe that you will come, and be our judge.

Come then, Lord, and help your people,
bought with the price of your own blood,
and bring us with your saints
to glory everlasting.

Save your people, Lord, and bless your inheritance.
— Govern and uphold them now and always.

Day by day we bless you.
— We praise your name for ever.

Keep us today, Lord, from all sin.
— Have mercy on us, Lord, have mercy.

Lord, show us your love and mercy,
— for we have put our trust in you.

In you, Lord, is our hope:
— And we shall never hope in vain.

CONCLUDING PRAYER

Grant, we pray, almighty God,
that no tempests may disturb us,
for you have set us fast on the rock
of the Apostle Peter’s confession of faith.
Through our Lord Jesus Christ, your Son,
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.
