Advent
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 also to the anniversary of the Lord's birth on Christmas. The final days of Advent, from December 17 to December 24, focus particularly on our preparation for the celebrations of the Nativity of our Lord (Christmas).
The Catechism of the Catholic Church stresses the two-fold meaning of this coming : "When the Church celebrates the liturgy of Advent each year, she makes present this ancient expectancy of the Messiah, for by sharing in the long preparation for the Saviors first coming, the faithful renew their ardent desire for His second coming" (No. 524).
The celebration of Advent has evolved in the spiritual life of the Church. The importance of this season remains to focus on the coming of our Lord. (Advent comes from the Latin adventus, meaning coming.)
Therefore, on one hand, the faithful reflect back and are encouraged to celebrate the anniversary of the Lords first coming into this world. We ponder again the great mystery of the incarnation when our Lord humbled Himself, taking on our humanity, and entered our time and space to free us from sin. On the other hand, we recall in the Creed that our Lord will come again to judge the living and the dead and that we must be ready to meet Him.
A good, pious way to help us in our Advent preparation has been the use of the Advent wreath. The wreath is a circle, which has no beginning or end: So we call to mind how our lives, here and now, participate in the eternity of Gods plan of salvation and how we hope to share eternal life in the Kingdom of Heaven. The wreath is made of fresh plant material, because Christ came to give us new life through His passion, death, and resurrection. Three candles are purple, symbolizing penance, preparation, and sacrifice; the pink candle symbolizes the same but highlights the third Sunday of Advent, Gaudete Sunday, when we rejoice because our preparation is now half-way finished.
The light represents Christ, who entered this world to scatter the darkness of evil and show us the way of righteousness. The progression of lighting candles shows our increasing readiness to meet our Lord.
Join with your parish to celebrate the Season of Advent.
