At Holy Child Church
The Rorate Caeli Mass is a traditional Latin Mass wherein the Mass of the Blessed Virgin Mary for Advent is offered just before dawn, lit only by candlelight.  
The interplay of light and darkness speak to the meaning of Advent and the coming of the Light of the world.  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 our Faith is illumined by Christ.
