Saint Matthew 9:14-15.
Book of Isaiah 58:1-9a.
Thus says the Lord GOD: Cry out full-throated and unsparingly, lift up your voice like a trumpet blast; Tell my people their wickedness, and the house of Jacob their sins. They seek me day after day, and desire to know my ways, Like a nation that has done what is just and not abandoned the law of their God; they ask me to declare what is due them, pleased to gain access to God. "Why do we fast, and you do not see it? afflict ourselves, and you take no note of it?" Lo, on your fast day you carry out your own pursuits, and drive all your laborers. Yes, your fast ends in quarreling and fighting, striking with wicked claw. Would that today you might fast so as to make your voice heard on high! Is this the manner of fasting I wish, of keeping a day of penance: That a man bow his head like a reed, and lie in sackcloth and ashes? Do you call this a fast, a day acceptable to the LORD? This, rather, is the fasting that I wish: releasing those bound unjustly, untying the thongs of the yoke; Setting free the oppressed, breaking every yoke; Sharing your bread with the hungry, sheltering the oppressed and the homeless; Clothing the naked when you see them, and not turning 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!
Have mercy on me, God, in your goodness; in your abundant compassion blot out my offense. Wash away all my guilt; from my sin cleanse me. For I know my offense; my sin is always before me. Against you alone have I sinned; I have done such evil in your sight that you are just in your sentence, blameless when you condemn. For you do not desire sacrifice; a burnt offering you would not accept. My sacrifice, God, is a broken spirit; God, do not spurn a broken, humbled heart.
Holy Gospel of Jesus Christ according to Saint Matthew 9:14-15.
The disciples of John approached Jesus and said, «Why do we and the Pharisees fast much, but your disciples do not fast?» Jesus answered them, "Can the wedding guests mourn as long as the bridegroom is with them? The days will come when the bridegroom is taken away from them, and then they will fast.
