The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2019-12-22:
Is 7:10-14
Ps 24:1-2, 3-4, 5-6
R. (7c and 10b)
Let the Lord enter;he is king of glory.
The LORD’s are the earth and its fullness;
the world and those who dwell in it.
For he founded it upon the seas
and established it upon the rivers.
R.Let the Lord enter;he is king of glory.
Who can ascend the mountain of the LORD?
or who may stand in his holy place?
One whose hands are sinless, whose heart is clean,
who desires not what is vain.
R.Let the Lord enter;he is king of glory.
He shall receive a blessing from the LORD,
a reward from God his savior.
Such is the race that seeks for him,
that seeks the face of the God of Jacob.
R.Let the Lord enter;he is king of glory.
Rom 1:1-7
Paul, a slave of Christ Jesus,
called to be an apostle and set apart for the gospel of God,
which he promised previously through his prophets in the holy Scriptures,
the gospel about his Son, descended from David according to the flesh,
but established as Son of God in power
according to the Spirit of holiness
through resurrection from the dead, Jesus Christ our Lord.
Through him we have received the grace of apostleship,
to bring about the obedience of faith,
for the sake of his name, among all the Gentiles,
among whom are you also, who are called to belong to Jesus Christ;
to all the beloved of God in Rome, called to be holy.
Grace to you and peace from God our Father
and the Lord Jesus Christ.
Mt 1:18-24
