Book of Isaiah (Is 7: 10-14 ; 8: 10)

Behold, a virgin shall conceive.

The LORD spoke to Ahaz, saying:

Ask for a sign from the LORD, your God;
let it be deep as the nether world, or high as the sky!

But Ahaz answered,

“I will not ask! I will not tempt the LORD!”

Then Isaiah said:

“Listen, O house of David!
Is it not enough for you to weary people,
must you also weary my God?
Therefore the Lord himself will give you this sign:
the virgin shall be with child, and bear a son,
and shall name him Emmanuel,
which means "God is with us!”

— The word of the Lord.

Responsorial Psalm

Ps 40: 7-8a, 8b-9, 10, 11

Here I am, Lord; I come to do your will.

Sacrifice or oblation you wished not,
but ears open to obedience you gave me.
Holocausts or sin-offerings you sought not;
then said I, “Behold I come.”

“In the written scroll it is prescribed for me,
To do your will, O my God, is my delight,
and your law is within my heart!”

I announced your justice in the vast assembly;
I did not restrain my lips, as you, O LORD, know.

Your justice I kept not hid within my heart;
your faithfulness and your salvation I have spoken of;
I have made no secret of your kindness and your truth
in the vast assembly.

Letter to the Hebrews (Heb 10: 4-10)

I have come to do your will, O God, as it is written of me in the roll of the book.

Brothers and sisters:
It is impossible that the blood of bulls and goats
take away sins.
For this reason, when Christ came into the world, he said:

“Sacrifice and offering you did not desire,
but a body you prepared for me;
in holocausts and sin offerings you took no delight.
Then I said, ‘As is written of me in the scroll,
behold, I come to do your will, O God.’”

First he says,

“Sacrifices and offerings,
holocausts and sin offerings,
you neither desired nor delighted in.”

These are offered according to the law.
Then he says,

“Behold, I come to do your will.”

He takes away the first to establish the second.
By this “will,” we have been consecrated
through the offering of the Body of Jesus Christ once for all.

— The word of the Lord.

Gospel

Glory and praise to you, O Christ.

The Word of God became flesh and made his dwelling among us; and we saw his glory.

Glory and praise to you, O Christ.

Gospel of Jesus Christ according to Saint Luke (Lk 1: 26-38)

You will conceive in your womb and bear a son.

The angel Gabriel was sent from God
to a town of Galilee called Nazareth,
to a virgin betrothed to a man named Joseph,
of the house of David,
and the virgin's name was Mary.

And coming to her, he said,

“Hail, full of grace! The Lord is with you.”

But she was greatly troubled at what was said
and pondered what sort of greeting this might be.

Then the angel said to her,

“Do not be afraid, Mary,
for you have found favor with God.
Behold, you will conceive in your womb and bear a son,
and you shall name him Jesus.
He will be great and will be called Son of the Most High,
and the Lord God will give him the throne of David his father,
and he will rule over the house of Jacob forever,
and of his Kingdom there will be no end.”

But Mary said to the angel,

“How can this be,
since I have no relations with a man?”

And the angel said to her in reply,

“The Holy Spirit will come upon you,
and the power of the Most High will overshadow you.
Therefore the child to be born
will be called holy, the Son of God.
And behold, Elizabeth, your relative,
has also conceived a son in her old age,
and this is the sixth month for her who was called barren;
for nothing will be impossible for God.”

Mary said,

“Behold, I am the handmaid of the Lord.
May it be done to me according to your word.”

Then the angel departed from her.

The Acts the Apostles (Acts 4: 32-35)

One heart and mind.

The community of believers was of one heart and mind,
and no one claimed that any of his possessions was his own,
but they had everything in common.
With great power the apostles bore witness
to the resurrection of the Lord Jesus,
and great favor was accorded them all.
There was no needy person among them,
for those who owned property or houses would sell them,
bring the proceeds of the sale,
and put them at the feet of the apostles,
and they were distributed to each according to need.

— The word of the Lord.

Responsorial Psalm

Ps 118: 2-4, 13-15, 22-24

Give thanks to the LORD, for he is good, his love is everlasting.

Let the house of Israel say,
“His mercy endures forever.”
Let the house of Aaron say,
“His mercy endures forever.”
Let those who fear the LORD say,
“His mercy endures forever.”

I was hard pressed and was falling,
but the LORD helped me.
My strength and my courage is the LORD,
and he has been my savior.
The joyful shout of victory
in the tents of the just:

The stone which the builders rejected
has become the cornerstone.
By the LORD has this been done;
it is wonderful in our eyes.
This is the day the LORD has made;
let us be glad and rejoice in it.

First Letter of Saint John (1 Jn 5: 1-6)

Whoever is begotten by God conquers the world.

Beloved:
Everyone who believes that Jesus is the Christ is begotten by God,
and everyone who loves the Father
loves also the one begotten by him.
In this way we know that we love the children of God
when we love God and obey his commandments.
For the love of God is this,
that we keep his commandments.
And his commandments are not burdensome,
for whoever is begotten by God conquers the world.
And the victory that conquers the world is our faith.
Who indeed is the victor over the world
but the one who believes that Jesus is the Son of God?

This is the one who came through water and blood, Jesus Christ,
not by water alone, but by water and blood.
The Spirit is the one that testifies,
and the Spirit is truth.

— The word of the Lord.

Gospel

Alleluia, alleluia.

You believe in me, Thomas, because you have seen me, says the Lord; Blessed are those who have not seen me, but still believe!

Alleluia, alleluia.

Gospel of Jesus Christ according to Saint John (Jn 20: 19-31)

Now a week later, Jesus came.

On the evening of that first day of the week,
when the doors were locked, where the disciples were,
for fear of the Jews,
Jesus came and stood in their midst
and said to them,

“Peace be with you.”

When he had said this, he showed them his hands and his side.
The disciples rejoiced when they saw the Lord.
Jesus said to them again,

“Peace be with you.
As the Father has sent me, so I send you.”

And when he had said this, he breathed on them and said to them,

“Receive the Holy Spirit.
Whose sins you forgive are forgiven them,
and whose sins you retain are retained.”

Thomas, called Didymus, one of the Twelve,
was not with them when Jesus came.
So the other disciples said to him,

“We have seen the Lord.”

But he said to them,

“Unless I see the mark of the nails in his hands
and put my finger into the nailmarks
and put my hand into his side, I will not believe.”

Now a week later his disciples were again inside
and Thomas was with them.
Jesus came, although the doors were locked,
and stood in their midst and said,

“Peace be with you.”

Then he said to Thomas,

“Put your finger here and see my hands,
and bring your hand and put it into my side,
and do not be unbelieving, but believe.”

Thomas answered and said to him,

“My Lord and my God!”

Jesus said to him,

“Have you come to believe because you have seen me?
Blessed are those who have not seen and have believed.”

Now Jesus did many other signs in the presence of his disciples
that are not written in this book.
But these are written that you may come to believe
that Jesus is the Christ, the Son of God,
and that through this belief you may have life in his name.
