The Christian liturgical season of Advent is considered a time of spiritual preparation in the weeks leading up to Christmas. The devotional period begins on the fourth Sunday before Christmas day. Christian churches consider Advent a time to reflect on, and to celebrate the coming birth of Jesus.CRI/Voice, Institute: The Christian Season of Advent
The Advent Wreath
The Advent Wreath, a common part of Advent tradition and celebration, is believed to have originated in Germany and Scandinavia during winter solstice celebrations. A traditional circular Advent wreath is made of evergreens and four candles. Three of the candles are purple and a fourth is rose-colored. On each Sunday of Advent, a candle is lit to help mark the passage of time before the coming of the Christ child.American Catholic: Advent FAQs
