The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2021-02-14:
Acts 13:46-49
46And Paul and Barnabas spoke out boldly, saying, "It was necessary that the word of God should be spoken first to you. Since you thrust it from you, and judge yourselves unworthy of eternal life, behold, we turn to the Gentiles. 47For so the Lord has commanded us, saying, `I have set you to be a light for the Gentiles, that you may bring salvation to the uttermost parts of the earth.'" 48And when the Gentiles heard this, they were glad and glorified the word of God;and as many as were ordained to eternal life believed. 49And the word of the Lord spread throughout all the region.
Psalms 117:1-2
1Praise the LORD, all nations! Extol him, all peoples! 2For great is his steadfast love toward us;and the faithfulness of the LORD endures for ever. Praise the LORD!
Luke 10:1-9
1After this the Lord appointed seventy others, and sent them on ahead of him, two by two, into every town and place where he himself was about to come. 2And he said to them, "The harvest is plentiful, but the laborers are few;pray therefore the Lord of the harvest to send out laborers into his harvest. 3Go your way;behold, I send you out as lambs in the midst of wolves. 4Carry no purse, no bag, no sandals;and salute no one on the road. 5Whatever house you enter, first say, `Peace be to this house!' 6And if a son of peace is there, your peace shall rest upon him;but if not, it shall return to you. 7And remain in the same house, eating and drinking what they provide, for the laborer deserves his wages;do not go from house to house. 8Whenever you enter a town and they receive you, eat what is set before you;9heal the sick in it and say to them, `The kingdom of God has come near to you.'
Lv 13:1-2, 44-46
The Lord said to Moses and Aaron,
"If someone has on his skin a scab or pustule or blotch
which appears to be the sore of leprosy,
he shall be brought to Aaron, the priest,
or to one of the priests among his descendants.
If the man is leprous and unclean,
the priest shall declare him unclean
by reason of the sore on his head.
"The one who bears the sore of leprosy
shall keep his garments rent and his head bare,
and shall muffle his beard;
he shall cry out, 'Unclean, unclean!'
As long as the sore is on him he shall declare himself unclean,
since he is in fact unclean.
He shall dwell apart, making his abode outside the camp."
Ps 32:1-2, 5, 11
R. (7)
I turn to you, Lord, in time of trouble, and you fill me with the joy of salvation.
Blessed is he whose fault is taken away,
whose sin is covered.
Blessed the man to whom the LORD imputes not guilt,
in whose spirit there is no guile.
R.I turn to you, Lord, in time of trouble, and you fill me with the joy of salvation.
Then I acknowledged my sin to you,
my guilt I covered not.
I said, "I confess my faults to the LORD,"
and you took away the guilt of my sin.
R.I turn to you, Lord, in time of trouble, and you fill me with the joy of salvation.
Be glad in the LORD and rejoice, you just;
exult, all you upright of heart.
R.I turn to you, Lord, in time of trouble, and you fill me with the joy of salvation.
1 Cor 10:31-11:1
Brothers and sisters,
Whether you eat or drink, or whatever you do,
do everything for the glory of God.
Avoid giving offense, whether to the Jews or Greeks or
the church of God,
just as I try to please everyone in every way,
not seeking my own benefit but that of the many,
that they may be saved.
Be imitators of me, as I am of Christ.
Mk 1:40-45
A leper came to Jesus and kneeling down begged him and said,
"If you wish, you can make me clean."
Moved with pity, he stretched out his hand,
touched him, and said to him,
"I do will it. Be made clean."
The leprosy left him immediately, and he was made clean.
Then, warning the him sternly, he dismissed him at once.
He said to him, "See that you tell no one anything,
but go, show yourself to the priest
and offer for your cleansing what Moses prescribed;
that will be proof for them."
The man went away and began to publicize the whole matter.
He spread the report abroad
so that it was impossible for Jesus to enter a town openly.
He remained outside in deserted places,
and people kept coming to him from everywhere.
