The Rorate Mass is lit only by candlelight. As a votive Mass in Mary's honor, white vestments are worn instead of Advent violet. In the dimly lit setting, priests and faithful prepare to honor the Light of the
world, Who is soon to be born, and offer praise to God for the gift of Our Lady. As the Mass proceeds and sunrise approaches, the church becomes progressively brighter, illumined by the sun as Christ illuminates our Faith. The name of the Mass comes from the first two words of the introductory antiphon sung in honor of our Lady.
