The Advent wreath is a circular garland representing eternity. Each of its candles symbolizes an aspect of preparation for Jesus' arrival. The first purple candle, lit on the first Sunday, represents hope. The second purple candle, lit the following week, represents love. On the third Sunday a pink candle for joy is lit. The fourth and final purple candle, representing peace, is lit on the fourth Sunday. The white center candle, lit on Christmas Eve, symbolizes Christ and purity through his life.
