The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2020-12-13:
2 Corinthians 10:17--11:2
1017"Let him who boasts, boast of the Lord." 18For it is not the man who commends himself that is accepted, but the man whom the Lord commends.111I wish you would bear with me in a little foolishness. Do bear with me! 2I feel a divine jealousy for you, for I betrothed you to Christ to present you as a pure bride to her one husband.
Psalms 31:3-4, 6, 8, 16-17
2Incline thy ear to me, rescue me speedily! Be thou a rock of refuge for me, a strong fortress to save me! 3Yea, thou art my rock and my fortress;for thy name's sake lead me and guide me, 5Into thy hand I commit my spirit;thou hast redeemed me, O LORD, faithful God. 7I will rejoice and be glad for thy steadfast love, because thou hast seen my affliction, thou hast taken heed of my adversities, 15My times are in thy hand;deliver me from the hand of my enemies and persecutors! 16Let thy face shine on thy servant;save me in thy steadfast love!
Matthew 25:1-13
1"Then the kingdom of heaven shall be compared to ten maidens who took their lamps and went to meet the bridegroom. 2Five of them were foolish, and five were wise. 3For when the foolish took their lamps, they took no oil with them;4but the wise took flasks of oil with their lamps. 5As the bridegroom was delayed, they all slumbered and slept. 6But at midnight there was a cry, `Behold, the bridegroom! Come out to meet him.' 7Then all those maidens rose and trimmed their lamps. 8And the foolish said to the wise, `Give us some of your oil, for our lamps are going out.' 9But the wise replied, `Perhaps there will not be enough for us and for you;go rather to the dealers and buy for yourselves.' 10And while they went to buy, the bridegroom came, and those who were ready went in with him to the marriage feast;and the door was shut. 11Afterward the other maidens came also, saying, `Lord, lord, open to us.' 12But he replied, `Truly, I say to you, I do not know you.' 13Watch therefore, for you know neither the day nor the hour.
is 61:1-2a, 10-11
The spirit of the Lord GOD is upon me,
because the LORD has anointed me;
he has sent me to bring glad tidings to the poor,
to heal the brokenhearted,
to proclaim liberty to the captives
and release to the prisoners,
to announce a year of favor from the LORD
and a day of vindication by our God.
I rejoice heartily in the LORD,
in my God is the joy of my soul;
for he has clothed me with a robe of salvation
and wrapped me in a mantle of justice,
like a bridegroom adorned with a diadem,
like a bride bedecked with her jewels.
As the earth brings forth its plants,
and a garden makes its growth spring up,
so will the Lord GOD make justice and praise
spring up before all the nations.
lk 1:46-48, 49-50, 53-54
R/ (Is 61:10b)
My soul rejoices in my God.
My soul proclaims the greatness of the Lord;
my spirit rejoices in God my Savior,
for he has looked upon his lowly servant.
From this day all generations will call me blessed:
R/
My soul rejoices in my God.
the Almighty has done great things for me,
and holy is his Name.
He has mercy on those who fear him
in every generation.
R/
My soul rejoices in my God.
He has filled the hungry with good things,
and the rich he has sent away empty.
He has come to the help of his servant Israel
for he has remembered his promise of mercy,
R/
My soul rejoices in my God.
1 thes 5:16-24
Brothers and sisters:
Rejoice always. Pray without ceasing.
In all circumstances give thanks,
for this is the will of God for you in Christ Jesus.
Do not quench the Spirit.
Do not despise prophetic utterances.
Test everything;retain what is good.
Refrain from every kind of evil.
May the God of peace make you perfectly holy
and may you entirely, spirit, soul, and body,
be preserved blameless for the coming of our Lord Jesus Christ.
The one who calls you is faithful,
and he will also accomplish it.
Is 61:1 (cited in Lk 4:18)
R.Alleluia, alleluia.
The Spirit of the Lord is upon me,
because he has anointed me
to bring glad tidings to the poor.
R.Alleluia, alleluia.
jn 1:6-8, 19-28
A man named John was sent from God.
He came for testimony, to testify to the light,
so that all might believe through him.
He was not the light,
but came to testify to the light.
And this is the testimony of John.
When the Jews from Jerusalem sent priests
and Levites to him
to ask him, "Who are you?"
He admitted and did not deny it,
but admitted, "I am not the Christ."
So they asked him,
"What are you then? Are you Elijah?"
And he said, "I am not."
"Are you the Prophet?"
He answered, "No."
So they said to him,
"Who are you, so we can give an answer to those who sent us?
What do you have to say for yourself?"
He said:
"I am
the voice of one crying out in the desert, ‘make straight the way of the Lord,’
"
as Isaiah the prophet said."
Some Pharisees were also sent.
They asked him,
"Why then do you baptize
if you are not the Christ or Elijah or the Prophet?"
John answered them,
"I baptize with water;
but there is one among you whom you do not recognize,
the one who is coming after me,
whose sandal strap I am not worthy to untie."
This happened in Bethany across the Jordan,
where John was baptizing.
