Mass begins in darkness before sunrise, with only candles lighting the church to remind us of a world in darkness and sin that is anticipating the coming of the “Light of the World.” As Mass progresses, the church becomes brighter until the risen sun fills it with the light of day. As a votive Mass for the Blessed Mother, white vestments are worn instead of the violet normally used during Advent. The Mass readings and prayers highlight the prophecies of the coming of Christ and Mary’s role in bringing the Light into the world.
