The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2021-05-02:
1 John 5:1-5
1Every one who believes that Jesus is the Christ is a child of God, and every one who loves the parent loves the child. 2By this we know that we love the children of God, when we love God and obey his commandments. 3For this is the love of God, that we keep his commandments. And his commandments are not burdensome. 4For whatever is born of God overcomes the world;and this is the victory that overcomes the world, our faith. 5Who is it that overcomes the world but he who believes that Jesus is the Son of God?
Psalms 37:3-6, 30-31
3Trust in the LORD, and do good;so you will dwell in the land, and enjoy security. 4Take delight in the LORD, and he will give you the desires of your heart. 5Commit your way to the LORD;trust in him, and he will act. 6He will bring forth your vindication as the light, and your right as the noonday. 30The mouth of the righteous utters wisdom, and his tongue speaks justice. 31The law of his God is in his heart;his steps do not slip.
Matthew 10:22-25
22and you will be hated by all for my name's sake. But he who endures to the end will be saved. 23When they persecute you in one town, flee to the next;for truly, I say to you, you will not have gone through all the towns of Israel, before the Son of man comes. 24"A disciple is not above his teacher, nor a servant above his master;25it is enough for the disciple to be like his teacher, and the servant like his master. If they have called the master of the house Be-el'zebul, how much more will they malign those of his household.
Acts 9:26-31
When Saul arrived in Jerusalem he tried to join the disciples,
but they were all afraid of him,
not believing that he was a disciple.
Then Barnabas took charge of him and brought him to the apostles,
and he reported to them how he had seen the Lord,
and that he had spoken to him,
and how in Damascus he had spoken out boldly in the name of Jesus.
He moved about freely with them in Jerusalem,
and spoke out boldly in the name of the Lord.
He also spoke and debated with the Hellenists,
but they tried to kill him.
And when the brothers learned of this,
they took him down to Caesarea
and sent him on his way to Tarsus.
The church throughout all Judea, Galilee, and Samaria was at peace.
It was being built up and walked in the fear of the Lord,
and with the consolation of the Holy Spirit it grew in numbers.
Ps 22:26-27, 28, 30, 31-32
R. (26a)
I will praise you, Lord, in the assembly of your people.
or:
R.Alleluia.
I will fulfill my vows before those who fear the LORD.
The lowly shall eat their fill;
they who seek the LORD shall praise him:
"May your hearts live forever!"
R.I will praise you, Lord, in the assembly of your people.
or:
R.Alleluia.
All the ends of the earth
shall remember and turn to the LORD;
all the families of the nations
shall bow down before him.
R.I will praise you, Lord, in the assembly of your people.
or:
R.Alleluia.
To him alone shall bow down
all who sleep in the earth;
before him shall bend
all who go down into the dust.
R.I will praise you, Lord, in the assembly of your people.
or:
R.Alleluia.
And to him my soul shall live;
my descendants shall serve him.
Let the coming generation be told of the LORD
that they may proclaim to a people yet to be born
the justice he has shown.
R.I will praise you, Lord, in the assembly of your people.
or:
R.Alleluia.
1 Jn 3:18-24
Children, let us love not in word or speech
but in deed and truth.
Now this is how we shall know that we belong to the truth
and reassure our hearts before him
in whatever our hearts condemn,
for God is greater than our hearts and knows everything.
Beloved, if our hearts do not condemn us,
we have confidence in God
and receive from him whatever we ask,
because we keep his commandments and do what pleases him.
And his commandment is this:
we should believe in the name of his Son, Jesus Christ,
and love one another just as he commanded us.
Those who keep his commandments remain in him, and he in them,
and the way we know that he remains in us
is from the Spirit he gave us.
Jn 15:1-8
Jesus said to his disciples:
"I am the true vine, and my Father is the vine grower.
He takes away every branch in me that does not bear fruit,
and every one that does he prunes so that it bears more fruit.
You are already pruned because of the word that I spoke to you.
Remain in me, as I remain in you.
Just as a branch cannot bear fruit on its own
unless it remains on the vine,
so neither can you unless you remain in me.
I am the vine, you are the branches.
Whoever remains in me and I in him will bear much fruit,
because without me you can do nothing.
Anyone who does not remain in me
will be thrown out like a branch and wither;
people will gather them and throw them into a fire
and they will be burned.
If you remain in me and my words remain in you,
ask for whatever you want and it will be done for you.
By this is my Father glorified,
that you bear much fruit and become my disciples."
