This reading can be used during the Easter season.
Summary: In heaven, a multitude praises God, celebrating the arrival of the Lamb’s wedding day. The faithful rejoice, and the blessed are invited to this joyful feast.
I, John, heard what sounded like the loud voice of a great multitude in heaven, saying:
“Alleluia! Salvation, glory, and might belong to our God.”
Then a voice coming from a heavenly throne said:
“Praise our God, all you his servants, and you who revere him, small and great.”
Then I heard something like the sound of a great multitude or the sound of rushing water or mighty peals of thunder, as they said:
“Alleluia! The Lord has established his reign, our God, the almighty. Let us rejoice and be glad and give him glory.
For the wedding day of the Lamb has come, his bride has made herself ready. She was allowed to wear a bright, clean linen garment.”
(The linen represents the righteous deeds of the holy ones.)
Then an angel said to me, “Write this: Blessed are those who have been called to the wedding feast of the Lamb.”
