Isaiah 58:1-4, 6-9a New Revised Standard Version (NRSV)

58 Shout out, do not hold back!
    Lift up your voice like a trumpet!
Announce to my people their rebellion,
    to the house of Jacob their sins.
² Yet day after day they seek me
    and delight to know my ways,
as if they were a nation that practiced righteousness
    and did not forsake the ordinance of their God;
they ask of me righteous judgments,
    they delight to draw near to God.
³ “Why do we fast, but you do not see?
    Why humble ourselves, but you do not notice?”
Look, you serve your own interest on your fast day,
    and oppress all your workers.
⁴ Look, you fast only to quarrel and to fight
    and to strike with a wicked fist.
Such fasting as you do today
    will not make your voice heard on high.

⁶ Is not this the fast that I choose:
    to loose the bonds of injustice,
    to undo the thongs of the yoke,
to let the oppressed go free,
    and to break every yoke?
⁷ Is it not to share your bread with the hungry,
    and bring the homeless poor into your house;
when you see the naked, to cover them,
    and not to hide yourself from your own kin?
⁸ Then your light shall break forth like the dawn,
    and your healing shall spring up quickly;
your vindicator shall go before you,
    the glory of the Lord shall be your rear guard.
⁹ Then you shall call, and the Lord will answer;
    you shall cry for help, and he will say, Here I am.

1 Corinthians 2:1-9 

1 When I came to you, brothers and sisters, I did not come proclaiming the mystery of God to you in lofty words or wisdom. ² For I decided to know nothing among you except Jesus Christ, and him crucified. ³ And I came to you in weakness and in fear and in much trembling. ⁴ My speech and my proclamation were not with plausible words of wisdom, but with a demonstration of the Spirit and of power, ⁵ so that your faith might rest not on human wisdom but on the power of God.

⁶ Yet among the mature we do speak wisdom, though it is not a wisdom of this age or of the rulers of this age, who are doomed to perish. ⁷ But we speak God’s wisdom, secret and hidden, which God decreed before the ages for our glory. ⁸ None of the rulers of this age understood this; for if they had, they would not have crucified the Lord of glory. ⁹ But, as it is written,

“What no eye has seen, nor ear heard,
    nor the human heart conceived,
what God has prepared for those who love him”—

Gospel Reading

Matthew 5:13-20 

¹³ “You are the salt of the earth; but if salt has lost its taste, how can its saltiness be restored? It is no longer good for anything, but is thrown out and trampled under foot.

¹⁴ “You are the light of the world. A city built on a hill cannot be hid. ¹⁵ No one after lighting a lamp puts it under the bushel basket, but on the lampstand, and it gives light to all in the house. ¹⁶ In the same way, let your light shine before others, so that they may see your good works and give glory to your Father in heaven.

¹⁷ “Do not think that I have come to abolish the law or the prophets; I have come not to abolish but to fulfill. ¹⁸ For truly I tell you, until heaven and earth pass away, not one letter, not one stroke of a letter, will pass from the law until all is accomplished. ¹⁹ Therefore, whoever breaks one of the least of these commandments, and teaches others to do the same, will be called least in the kingdom of heaven; but whoever does them and teaches them will be called great in the kingdom of heaven. ²⁰ For I tell you, unless your righteousness exceeds that of the scribes and Pharisees, you will never enter the kingdom of heaven.

Thanks be to God!
