First Reading for Common of Virgins (During the Easter Season) - Daily Catholic Mass Reading

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."

A voice coming from the 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 the angel said to me, "Write this: Blessed are those who have been called to the wedding feast of the Lamb."
