Advent begins Saturday evening, November 26.

From the USCCB website:

Beginning the Church's liturgical year, Advent (from, "ad-venire" in Latin or "to come to") is the season encompassing the four Sundays (and weekdays) leading up to the celebration of Christmas

The Advent season is a time of preparation that directs our hearts and minds to Christ’s second coming at the end of time and to the anniversary of Our Lord’s birth on Christmas. From the earliest days of the Church, people have been fascinated by Jesus’ promise to come back. But the scripture readings during Advent tell us not to waste our time with predictions. Advent is not about speculation. Our Advent readings call us to be alert and ready, not weighted down and distracted by the cares of this world (Lk 21:34-36). Like Lent, the liturgical color for Advent is purple since both are seasons that prepare us for great feast days. Advent also includes an element of penance in the sense of preparing, quieting, and disciplining our hearts for the full joy of Christmas.

As we prepare for Christmas, the General Instruction of the Roman Missal notes some differences to the Mass that should be observed during the season. For instance, the priest wears violet or purple during Advent, except for the Third Sunday of Advent (Gaudete Sunday) when rose may be worn (GIRM, no. 346). Aside from what the priest wears, other aesthetic changes in the Church can include a more modestly decorated altar.

The final days of Advent, from December 17 to December 24, we focus on our preparation for the celebrations of the Nativity of our Lord at Christmas. In particular, the "O" Antiphons are sung during this period and have been by the Church since at least the eighth century. They are a magnificent theology that uses ancient biblical imagery drawn from the messianic hopes of the Old Testament to proclaim the coming of Christ as the fulfillment not only of Old Testament hopes, but of present ones as well.

Advent devotions including the Advent wreath, remind us of the meaning of the season. Our Advent calendar above can help you fully enter into the season with daily activity and prayer suggestions to prepare you spiritually for the birth of Jesus Christ. 

Advent Music at Mass

Because it is a penitential season, we do not sing the Gloria at Masses during Advent. We are fasting from this song in anticipation of singing it with greater joy on Christmas. The opening words of the Gloria come from the angelic greeting to the shepherds.

As we have for many years at OLMC, we chant a few parts of the Mass in Latin (and Greek). Occasionally, we get asked, “why do we sing in Latin?” Some people are under the mistaken impression that Vatican II did away with Latin in Catholic worship. To the contrary, the Council encouraged its continued use, while also encouraging more use of the vernacular. This article gives a good explanation.

If this seems strange to you, please spend a few minutes practicing these parts of the Mass.

Kyrie (Lord, have mercy)

Sanctus (Holy, Holy)

Post Consecrationem (After the Consecration)

Agnus Dei (Lamb of God)
