HYMN

Your hand, O Lord, has guided
Your Church from age to age;
The wondrous tale is written
So clearly on each page;
Our fathers praised your goodness,
And we their deeds record;
And both to this bear witness:
One Church, one Faith, one Lord.

Your heralds brought glad tidings
To greatest and to least;
They told all men to hasten
To share the great King’s feast;
And this was all their teaching
In every deed and word,
To all alike proclaiming:
One Church, one Faith, one Lord.

Through many days of darkness,
Through many scenes of strife,
The faithful few fought bravely
To guard the Christian life;
Their gospel of redemption,
Sin pardoned, man restored,
Was all in this enfolded:
One Church, one Faith, one Lord.

Your mercy will not fail us,
Nor leave your work undone;
With all your strength to help us,
The vict’ry shall be won;
And then by men and angels
Your name shall be adored,
And this shall be their anthem:
One Church, one Faith, one Lord.

PSALMODY

Antiphon 1: Their voice has gone out to the limits of the earth, their words to the ends of the world.

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...

Antiphon 1: Their voice has gone out to the limits of the earth, their words to the ends of the world.


Antiphon 2: They proclaimed what God has done for us; they grasped the meaning of his deeds.

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 depths 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...

Antiphon 2: They proclaimed what God has done for us; they grasped the meaning of his deeds.


Antiphon 3: God's holiness was revealed by them; all nations saw God's glory.

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...

Antiphon 3: God's holiness was revealed by them; all nations saw God's glory.


They proclaimed the Lord's praises, told of his power to save.
- And of the wonders he had worked.


FIRST READING

From the first letter of the apostle Paul to the Ephesians          4:1-16

I plead with you, as a prisoner for the Lord, to live in a manner worthy of the call you have received, with all humility and gentleness, with patience, bearing with one another through love, striving to preserve the unity of the spirit through the bond of peace:  one body and one Spirit, as you were also called to the one hope of your call; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all.

But grace was given to each of us according to the measure of Christ's gift. Therefore, it says:

   "He ascended on high and took prisoners captive;
   he gave gifts to men."

What does "he ascended" mean except that he also descended into the lower regions of the earth? The one who descended is also the one who ascended far above all the heavens, that he might fill all things.  

And he gave some as apostles, others as prophets, others as evangelists, others as pastors and teachers, to equip the holy ones for the work of ministry, for building up the body of Christ, until we all attain to the unity of faith and knowledge of the Son of God, to mature manhood, to the extent of the full stature of Christ.

Let us, then, be children no longer, tossed by waves and swept along by every wind of teaching arising from human trickery, from their cunning in the interests of deceitful scheming. Rather, living the truth in love, we should grow in every way into him who is the head, Christ, from whom the whole body, joined and held together by every supporting ligament, with the proper functioning of each part, brings about the body's growth and builds itself up in love.


RESPONSORY           2 Peter 1:21; Proverbs 2:6
No prophecy ever came from man.
   - The men who spoke the word of God were inspired by the Holy Spirit.

The Lord gives wisdom;
knowledge and understanding flow from his mouth.
   - The men who spoke the word of God were inspired by the Holy Spirit.

SECOND READING

From a homily by St Bede the Venerable, priest
(Hom. 21: CCL 122, 149-151)

Jesus saw him through the eyes of mercy and chose him

Jesus saw a man called Matthew sitting at the tax office, and he said to him: Follow me. Jesus saw Matthew, not merely in the usual sense, but more significantly with his merciful understanding of men.

He saw the tax collector and, because he saw him through the eyes of mercy and chose him, he said to him: Follow me. This following meant imitating the pattern of his life – not just walking after him. St. John tells us: Whoever says he abides in Christ ought to walk in the same way in which he walked.

And he rose and followed him. There is no reason for surprise that the tax collector abandoned earthly wealth as soon as the Lord commanded him. Nor should one be amazed that neglecting his wealth, he joined a band of men whose leader had, on Matthew’s assessment, no riches at all. Our Lord summoned Matthew by speaking to him in words. By an invisible, interior impulse flooding his mind with the light of grace, he instructed him to walk in his footsteps. In this way Matthew could understand that Christ, who was summoning him away from earthly possessions, had incorruptible treasures of heaven in his gift.

As he sat at table in the house, behold many tax collectors and sinners came and sat down with Jesus and his disciples. This conversion of one tax collector gave many men, those from his own profession and other sinners, an example of repentance and pardon. Notice also the happy and true anticipation of his future status as apostle and teacher of the nations. No sooner was he converted than Matthew drew after him a whole crowd of sinners along the same road to salvation. He took up his appointed duties while still taking his first steps in the faith, and from that hour he fulfilled his obligation and thus grew in merit. To see a deeper understanding of the great celebration Matthew held at his house, we must realise that he not only gave a banquet for the Lord at his earthly residence, but far more pleasing was the banquet set in his own heart which he provided through faith and love. Our Saviour attests to this: Behold I stand at the door and knock; if anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me.

On hearing Christ’s voice, we open the door to receive him, as it were, when we freely assent to his promptings and when we give ourselves over to doing what must be done. Christ, since he dwells in the hearts of his chosen ones through the grace of his love, enters so that he might eat with us and we with him. He ever refreshes us by the light of his presence insofar as we progress in our devotion to and longing for the things of heaven. He himself is delighted by such a pleasing banquet.


RESPONSORY

CANTICLE          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 shun 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.

V.  Save your people, Lord, and bless your inheritance;
R.  govern and uphold them, now and always.
V.  Day by day we bless you;
R.  we praise your name for ever.
V.  Keep us today, Lord, from all sin;
R.  have mercy on us, Lord, have mercy.
V.  Lord, show us your love and mercy;
R.  for we put our trust in you.
V.  In you, Lord, is our hope;
R.  and we shall never hope in vain.

The concluding part of the hymn may be omitted.


COLLECT
O God, who with untold mercy
were pleased to choose as an Apostle
Saint Matthew, the tax collector,
grant that, sustained by his example and intercession,
we may merit to hold firm in following you.
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.


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