Depicting the sacred mystery of Christmas in the ancient melodies of Gregorian chant, this recording will enrich anyone's experience of this holy season. The first Mass, the quietly joyful "Ad Missam in Vigilia," builds on the anticipation of the coming event, proclaiming the Good News of the salvation prepared for us by a loving God through the birth of His Son. The second Mass, the tender "Ad Missam in Nocte," is sung at the hour traditionally oberved as the time of Christ's birth. With exquisite beauty and strength, the Mass celebrated at dawn on Christmas Day, "Ad Missam in Aurora," expresses the coming of the Light into the world. The fourth Mass, "Ad Missam in Die," is a jubilant expression of the salvation and righteousness of God. This recording also includes special antiphons honoring the Virgin Mary.
