The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2025-01-12:
Hebrews 1:1-6
1In many and various ways God spoke of old to our fathers by the prophets;2but in these last days he has spoken to us by a Son, whom he appointed the heir of all things, through whom also he created the world.3He reflects the glory of God and bears the very stamp of his nature, upholding the universe by his word of power. When he had made purification for sins, he sat down at the right hand of the Majesty on high,4having become as much superior to angels as the name he has obtained is more excellent than theirs.5For to what angel did God ever say, "Thou art my Son, today I have begotten thee"? Or again, "I will be to him a father, and he shall be to me a son"?6And again, when he brings the first-born into the world, he says, "Let all God's angels worship him."
Psalms 97:1-2, 6-7, 9
1The LORD reigns; let the earth rejoice; let the many coastlands be glad! 2Clouds and thick darkness are round about him; righteousness and justice are the foundation of his throne. 6The heavens proclaim his righteousness; and all the peoples behold his glory. 7All worshipers of images are put to shame, who make their boast in worthless idols; all gods bow down before him. 9For thou, O LORD, art most high over all the earth; thou art exalted far above all gods.
Mark 1:14-20
14Now after John was arrested, Jesus came into Galilee, preaching the gospel of God, 15and saying, "The time is fulfilled, and the kingdom of God is at hand; repent, and believe in the gospel." 16And passing along by the Sea of Galilee, he saw Simon and Andrew the brother of Simon casting a net in the sea; for they were fishermen. 17And Jesus said to them, "Follow me and I will make you become fishers of men." 18And immediately they left their nets and followed him. 19And going on a little farther, he saw James the son of Zeb'edee and John his brother, who were in their boat mending the nets. 20And immediately he called them; and they left their father Zeb'edee in the boat with the hired servants, and followed him.
Is 42:1-4, 6-7
Thus says the LORD:
Here is my servant whom I uphold,
my chosen one with whom I am pleased,
upon whom I have put my spirit;
he shall bring forth justice to the nations,
not crying out, not shouting,
not making his voice heard in the street.
a bruised reed he shall not break,
and a smoldering wick he shall not quench,
until he establishes justice on the earth;
the coastlands will wait for his teaching.
I, the LORD, have called you for the victory of justice,
I have grasped you by the hand;
I formed you, and set you
as a covenant of the people,
a light for the nations,
to open the eyes of the blind,
to bring out prisoners from confinement,
and from the dungeon, those who live in darkness.
Ps 29:1-2, 3-4, 3, 9-10.
R. (11b)
The Lord will bless his people with peace.
Give to the LORD, you sons of God,
give to the LORD glory and praise,
Give to the LORD the glory due his name;
adore the LORD in holy attire.
R.The Lord will bless his people with peace.
The voice of the LORD is over the waters,
the LORD, over vast waters.
The voice of the LORD is mighty;
the voice of the LORD is majestic.
R.The Lord will bless his people with peace.
The God of glory thunders,
and in his temple all say, "Glory!"
The LORD is enthroned above the flood;
the LORD is enthroned as king forever.
R.The Lord will bless his people with peace.
Acts 10:34-38
Peter proceeded to speak to those gathered
in the house of Cornelius, saying:
"In truth, I see that God shows no partiality.
Rather, in every nation whoever fears him and acts uprightly
is acceptable to him.
You know the word that he sent to the Israelites
as he proclaimed peace through Jesus Christ, who is Lord of all,
what has happened all over Judea,
beginning in Galilee after the baptism
that John preached,
how God anointed Jesus of Nazareth
with the Holy Spirit and power.
He went about doing good
and healing all those oppressed by the devil,
for God was with him."
Lk 3:15-16, 21-22
The people were filled with expectation,
and all were asking in their hearts
whether John might be the Christ.
John answered them all, saying,
"I am baptizing you with water,
but one mightier than I is coming.
I am not worthy to loosen the thongs of his sandals.
He will baptize you with the Holy Spirit and fire."
After all the people had been baptized
and Jesus also had been baptized and was praying,
heaven was opened and the Holy Spirit descended upon him
in bodily form like a dove.
And a voice came from heaven,
"You are my beloved Son;
with you I am well pleased."
