The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2021-01-31:
Philippians 4:4-9
4Rejoice in the Lord always;again I will say, Rejoice. 5Let all men know your forbearance. The Lord is at hand. 6Have no anxiety about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. 7And the peace of God, which passes all understanding, will keep your hearts and your minds in Christ Jesus. 8Finally, brethren, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is gracious, if there is any excellence, if there is anything worthy of praise, think about these things. 9What you have learned and received and heard and seen in me, do;and the God of peace will be with you.
Psalms 103:1-4, 8-9, 13-14, 17-18
1Bless the LORD, O my soul;and all that is within me, bless his holy name! 2Bless the LORD, O my soul, and forget not all his benefits, 3who forgives all your iniquity, who heals all your diseases, 4who redeems your life from the Pit, who crowns you with steadfast love and mercy, 8The LORD is merciful and gracious, slow to anger and abounding in steadfast love. 9He will not always chide, nor will he keep his anger for ever. 13As a father pities his children, so the LORD pities those who fear him. 14For he knows our frame;he remembers that we are dust. 17But the steadfast love of the LORD is from everlasting to everlasting upon those who fear him, and his righteousness to children's children, 18to those who keep his covenant and remember to do his commandments.
Matthew 18:1-5
1At that time the disciples came to Jesus, saying, "Who is the greatest in the kingdom of heaven?" 2And calling to him a child, he put him in the midst of them, 3and said, "Truly, I say to you, unless you turn and become like children, you will never enter the kingdom of heaven. 4Whoever humbles himself like this child, he is the greatest in the kingdom of heaven. 5"Whoever receives one such child in my name receives me;
Dt 18:15-20
Moses spoke to all the people, saying:
"A prophet like me will the LORD, your God, raise up for you
from among your own kin;
to him you shall listen.
This is exactly what you requested of the LORD, your God, at Horeb
on the day of the assembly, when you said,
'Let us not again hear the voice of the LORD, our God,
nor see this great fire any more, lest we die.'
And the LORD said to me, 'This was well said.
I will raise up for them a prophet like you from among their kin,
and will put my words into his mouth;
he shall tell them all that I command him.
Whoever will not listen to my words which he speaks in my name,
I myself will make him answer for it.
But if a prophet presumes to speak in my name
an oracle that I have not commanded him to speak,
or speaks in the name of other gods, he shall die.'"
Ps 95:1-2, 6-7, 7-9
R. (8)
If today you hear his voice, harden not your hearts.
Come, let us sing joyfully to the LORD;
let us acclaim the rock of our salvation.
Let us come into his presence with thanksgiving;
let us joyfully sing psalms to him.
R.If today you hear his voice, harden not your hearts.
Come, let us bow down in worship;
let us kneel before the LORD who made us.
For he is our God,
and we are the people he shepherds, the flock he guides.
R.If today you hear his voice, harden not your hearts.
Oh, that today you would hear his voice:
"Harden not your hearts as at Meribah,
as in the day of Massah in the desert,
Where your fathers tempted me;
they tested me though they had seen my works."
R.If today you hear his voice, harden not your hearts.
1 Cor 7:32-35
Brothers and sisters:
I should like you to be free of anxieties.
An unmarried man is anxious about the things of the Lord,
how he may please the Lord.
But a married man is anxious about the things of the world,
how he may please his wife, and he is divided.
An unmarried woman or a virgin is anxious about the things of the Lord,
so that she may be holy in both body and spirit.
A married woman, on the other hand,
is anxious about the things of the world,
how she may please her husband.
I am telling you this for your own benefit,
not to impose a restraint upon you,
but for the sake of propriety
and adherence to the Lord without distraction.
Mk 1:21-28
Then they came to Capernaum,
and on the sabbath Jesus entered the synagogue and taught.
The people were astonished at his teaching,
for he taught them as one having authority and not as the scribes.
In their synagogue was a man with an unclean spirit;
he cried out, "What have you to do with us, Jesus of Nazareth?
Have you come to destroy us?
I know who you are?the Holy One of God!"
Jesus rebuked him and said,
"Quiet! Come out of him!"
The unclean spirit convulsed him and with a loud cry came out of him.
All were amazed and asked one another,
"What is this?
A new teaching with authority.
He commands even the unclean spirits and they obey him."
His fame spread everywhere throughout the whole region of Galilee.
