The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Sunday, 2017-02-05:
Hebrews 12:18-19, 21-24
18For you have not come to what may be touched, a blazing fire, and darkness, and gloom, and a tempest,19and the sound of a trumpet, and a voice whose words made the hearers entreat that no further messages be spoken to them.21Indeed, so terrifying was the sight that Moses said, "I tremble with fear."22But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering,23and to the assembly of the first-born who are enrolled in heaven, and to a judge who is God of all, and to the spirits of just men made perfect,24and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks more graciously than the blood of Abel.
Psalms 48:2-4, 9-11
1Great is the LORD and greatly to be praised in the city of our God! His holy mountain, 2beautiful in elevation, is the joy of all the earth, Mount Zion, in the far north, the city of the great King. 3Within her citadels God has shown himself a sure defense. 8As we have heard, so have we seen in the city of the LORD of hosts, in the city of our God, which God establishes for ever. [Selah] 9We have thought on thy steadfast love, O God, in the midst of thy temple. 10As thy name, O God, so thy praise reaches to the ends of the earth. Thy right hand is filled with victory;
Mark 6:7-13
7And he called to him the twelve, and began to send them out two by two, and gave them authority over the unclean spirits. 8He charged them to take nothing for their journey except a staff;no bread, no bag, no money in their belts;9but to wear sandals and not put on two tunics. 10And he said to them, "Where you enter a house, stay there until you leave the place. 11And if any place will not receive you and they refuse to hear you, when you leave, shake off the dust that is on your feet for a testimony against them." 12So they went out and preached that men should repent. 13And they cast out many demons, and anointed with oil many that were sick and healed them.
is 58:7-10
Thus says the LORD:
Share your bread with the hungry,
shelter the oppressed and the homeless;
clothe the naked when you see them,
and do not turn your back on your own.
Then your light shall break forth like the dawn,
and your wound shall quickly be healed;
your vindication shall go before you,
and the glory of the LORD shall be your rear guard.
Then you shall call, and the LORD will answer,
you shall cry for help, and he will say: Here I am!
If you remove from your midst
oppression, false accusation and malicious speech;
if you bestow your bread on the hungry
and satisfy the afflicted;
then light shall rise for you in the darkness,
and the gloom shall become for you like midday.

1 cor 2:1-5
When I came to you, brothers and sisters,
proclaiming the mystery of God,
I did not come with sublimity of words or of wisdom.
For I resolved to know nothing while I was with you
except Jesus Christ, and him crucified.
I came to you in weakness and fear and much trembling,
and my message and my proclamation
were not with persuasive words of wisdom,
but with a demonstration of Spirit and power,
so that your faith might rest not on human wisdom
but on the power of God.
mt 5:13-16
Jesus said to his disciples:
"You are the salt of the earth.
But if salt loses its taste, with what can it be seasoned?
It is no longer good for anything
but to be thrown out and trampled underfoot.
You are the light of the world.
A city set on a mountain cannot be hidden.
Nor do they light a lamp and then put it under a bushel basket;
it is set on a lampstand,
where it gives light to all in the house.
Just so, your light must shine before others,
that they may see your good deeds
and glorify your heavenly Father."
