REVELATION 15:1-4

1Then I saw another portent in heaven, great and wonderful, seven angels with seven plagues, which are the last, for with them the wrath of God is ended. 2And I saw what appeared to be a sea of glass mingled with fire, and those who had conquered the beast and its image and the number of its name, standing beside the sea of glass with harps of God in their hands. 3And they sing the song of Moses, the servant of God, and the song of the Lamb, saying, "Great and wonderful are thy deeds, O Lord God the Almighty! Just and true are thy ways, O King of the ages! 4Who shall not fear and glorify thy name, O Lord? For thou alone art holy. All nations shall come and worship thee, for thy judgments have been revealed."

Responsorial Psalm
PSALMS 98:1-3, 7-9

1O sing to the LORD a new song, for he has done marvelous things! His right hand and his holy arm have gotten him victory. 2The LORD has made known his victory, he has revealed his vindication in the sight of the nations. 3He has remembered his steadfast love and faithfulness to the house of Israel. All the ends of the earth have seen the victory of our God. 7Let the sea roar, and all that fills it; the world and those who dwell in it! 8Let the floods clap their hands; let the hills sing for joy together 9before the LORD, for he comes to judge the earth. He will judge the world with righteousness, and the peoples with equity.

Gospel
LUKE 21:12-19

12But before all this they will lay their hands on you and persecute you, delivering you up to the synagogues and prisons, and you will be brought before kings and governors for my name's sake. 13This will be a time for you to bear testimony. 14Settle it therefore in your minds, not to meditate beforehand how to answer; 15for I will give you a mouth and wisdom, which none of your adversaries will be able to withstand or contradict. 16You will be delivered up even by parents and brothers and kinsmen and friends, and some of you they will put to death; 17you will be hated by all for my name's sake. 18But not a hair of your head will perish. 19By your endurance you will gain your lives.
