We developed a script for our Sunday School for the ritual of lighting Advent candles at home. To do this yourself, you will need five candles. You could have them in a special Advent wreath or standing alone. Traditionally three candles are purple, one is pink and one is white, as you will see in the script and photos below, but you can use all the same color, too.
Here is the link to a downloadable pdf of the script: Advent Candle Lighting at Home
