The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2021-01-24:
Ephesians 3:8-12
8To me, though I am the very least of all the saints, this grace was given, to preach to the Gentiles the unsearchable riches of Christ, 9and to make all men see what is the plan of the mystery hidden for ages in God who created all things;10that through the church the manifold wisdom of God might now be made known to the principalities and powers in the heavenly places. 11This was according to the eternal purpose which he has realized in Christ Jesus our Lord, 12in whom we have boldness and confidence of access through our faith in him.
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.
John 15:9-17
9As the Father has loved me, so have I loved you;abide in my love. 10If you keep my commandments, you will abide in my love, just as I have kept my Father's commandments and abide in his love. 11These things I have spoken to you, that my joy may be in you, and that your joy may be full. 12"This is my commandment, that you love one another as I have loved you. 13Greater love has no man than this, that a man lay down his life for his friends. 14You are my friends if you do what I command you. 15No longer do I call you servants, for the servant does not know what his master is doing;but I have called you friends, for all that I have heard from my Father I have made known to you. 16You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide;so that whatever you ask the Father in my name, he may give it to you. 17This I command you, to love one another.
Jon 3:1-5, 10
The word of the LORD came to Jonah, saying:
"Set out for the great city of Nineveh,
and announce to it the message that I will tell you."
So Jonah made ready and went to Nineveh,
according to the LORD'S bidding.
Now Nineveh was an enormously large city;
it took three days to go through it.
Jonah began his journey through the city,
and had gone but a single day's walk announcing,
"Forty days more and Nineveh shall be destroyed, "
when the people of Nineveh believed God;
they proclaimed a fast
and all of them, great and small, put on sackcloth.
When God saw by their actions how they turned from their evil way,
he repented of the evil that he had threatened to do to them;
he did not carry it out.
Ps 25:4-5, 6-7, 8-9
R. (4a)
Teach me your ways, O Lord.
Your ways, O LORD, make known to me;
teach me your paths,
Guide me in your truth and teach me,
for you are God my savior.
R.Teach me your ways, O Lord.
Remember that your compassion, O LORD,
and your love are from of old.
In your kindness remember me,
because of your goodness, O LORD.
R.Teach me your ways, O Lord.
Good and upright is the LORD;
thus he shows sinners the way.
He guides the humble to justice
and teaches the humble his way.
R.Teach me your ways, O Lord.
1 Cor 7:29-31
I tell you, brothers and sisters, the time is running out.
From now on, let those having wives act as not having them,
those weeping as not weeping,
those rejoicing as not rejoicing,
those buying as not owning,
those using the world as not using it fully.
For the world in its present form is passing away.
Mk 1:14-20
After John had been arrested,
Jesus came to Galilee proclaiming the gospel of God:
"This is the time of fulfillment.
The kingdom of God is at hand.
Repent, and believe in the gospel."
As he passed by the Sea of Galilee,
he saw Simon and his brother Andrew casting their nets into the sea;
they were fishermen.
Jesus said to them,
"Come after me, and I will make you fishers of men."
Then they abandoned their nets and followed him.
He walked along a little farther
and saw James, the son of Zebedee, and his brother John.
They too were in a boat mending their nets.
Then he called them.
So they left their father Zebedee in the boat
along with the hired men and followed him.
