This is the liturgy we’ll be using at GCR this Sunday:

Today we light the third candle of Advent, the candle that symbolizes joy.
This candle is pink in color, which represents joy and marks a shift during the Advent season from an attitude of repentance to one of rejoicing and celebration.
The joy of the Lord builds within us as the coming of the Savior draws near.
We rejoice together in the gift of salvation through the birth of Jesus Christ.
And we joyfully praise God for the coming fulfillment of his promises.

Luke 2:7-14
