The Rorate Mass is a Catholic tradition celebrated during Advent to honor the Virgin Mary. This unique mass takes place just before dawn, in the darkness, and is illuminated by candlelight. As the mass progresses, the church gradually brightens with the rising sun. Unlike the typical violet vestments of Advent, white vestments are worn. The name "Rorate" comes from the Latin phrase "Rorate caeli," meaning "Drop down, ye heavens." The interplay of light and darkness during the mass symbolizes the coming of the Light of the world.
