First Reading

Isaiah 26:1-6

1In that day, this canticle will be sung in the land of Judah. Within it will be set the city of our strength: Zion, a savior, a wall with a bulwark. 2Open the gates, and let the just people who guard the truth enter. 3The old error has gone away. You will serve peace: peace, for we have hoped in you. 4You have trusted in the Lord for all eternity, in the Lord God almighty forever. 5For he will bend down those living in the heights. He will bring low the lofty city. He will lower it, even to the ground. He will tear it down, even to the dust. 6The foot will tread it down: the feet of the poor, the steps of the indigent.
Responsorial Psalm

Psalm 117

1Alleluia. Confess to the Lord, for he is good, for his mercy is forever. 2Let Israel now say: For he is good, for his mercy is forever. 3Let the house of Aaron now say: For his mercy is forever. 4Let those who fear the Lord now say: For his mercy is forever. 5In my tribulation, I called upon the Lord. And the Lord heeded me with generosity. 6The Lord is my helper. I will not fear what man can do to me. 7The Lord is my helper. And I will look down upon my enemies. 8It is good to trust in the Lord, rather than to trust in man. 9It is good to hope in the Lord, rather than to hope in leaders. 10All the nations have surrounded me. And, in the name of the Lord, I have been avenged over them. 11Surrounding me, they closed in on me. And, in the name of the Lord, I have been avenged over them. 12They surrounded me like a swarm, and they burned like fire among the thorns. And, in the name of the Lord, I have been avenged over them. 13Having been pushed, I was overturned so as to fall. But the Lord took me up. 14The Lord is my strength and my praise. And he has become my salvation. 15A voice of exultation and salvation is in the tabernacles of the just. 16The right hand of the Lord has wrought virtue. The right hand of the Lord has exalted me. The right hand of the Lord has wrought virtue. 17I will not die, but I will live. And I will declare the works of the Lord. 18When chastising, the Lord chastised me. But he has not delivered me over to death. 19Open the gates of justice to me. I will enter them, and I will confess to the Lord. 20This is the gate of the Lord. The just will enter by it. 21I will confess to you because you have heard me. And you have become my salvation. 22The stone which the builders have rejected, this has become the head of the corner. 23By the Lord has this been done, and it is a wonder before our eyes. 24This is the day that the Lord has made. Let us exult and rejoice in it. 25O Lord, grant salvation to me. O Lord, grant good prosperity.

Gospel

Matthew 7:21, 24-27

21Not all who say to me, ‘Lord, Lord,’ will enter into the kingdom of heaven. But whoever does the will of my Father, who is in heaven, the same shall enter into the kingdom of heaven. 22Many will say to me in that day, ‘Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and perform many powerful deeds in your name?’ 23And then will I disclose to them: ‘I have never known you. Depart from me, you workers of iniquity.’ 24Therefore, everyone who hears these words of mine and does them shall be compared to a wise man, who built his house upon the rock. 25And the rains descended, and the floods rose up, and the winds blew, and rushed upon that house, but it did not fall, for it was founded on the rock. 26And everyone who hears these words of mine and does not do them shall be like a foolish man, who built his house upon the sand. 27And the rains descended, and the floods rose up, and the winds blew, and rushed upon that house, and it did fall, and great was its ruin.”
