By the Middle Ages, the Christians adapted this tradition and used Advent wreathes as part of their spiritual preparation for Christmas. After all, Christ is “the Light that came into the world” to dispel the darkness of sin and to radiate the truth and love of God (cf. John 3:19-21). By 1600, both Catholics and Lutherans had more formal practices surrounding the Advent wreath.
The symbolism of the Advent wreath is beautiful. The wreath is made of various evergreens, signifying continuous life. Even these evergreens have a traditional meaning which can be adapted to our faith: The laurel signifies victory over persecution and suffering; pine, holly, and yew, immortality; and cedar, strength and healing. Holly also has a special Christian symbolism: The prickly leaves remind us of the crown of thorns, and one English legend tells of how the cross was made of holly. The circle of the wreath, which has no beginning or end, symbolizes the eternity of God, the immortality of the soul, and the everlasting life found in Christ. Any pine cones, nuts, or seedpods used to decorate the wreath also symbolize life and resurrection. All together, the wreath of evergreens depicts the immortality of our soul and the new, everlasting life promised to us through Christ, the eternal Word of the Father, who entered our world becoming true man and who was victorious over sin and death through His own passion, death, and resurrection.
The four candles represent the four weeks of Advent. A tradition is that each week represents one thousand years, to sum to the 4,000 years from Adam and Eve until the Birth of the Savior. Three candles are purple and one is rose. The purple candles in particular symbolize the prayer, penance, and preparatory sacrifices and goods works undertaken at this time. The rose candle is lit on the third Sunday, Gaudete Sunday, when the priest also wears rose vestments at Mass; Gaudete Sunday is the Sunday of rejoicing, because the faithful have arrived at the midpoint of Advent, when their preparation is now half over and they are close to Christmas. The progressive lighting of the candles symbolizes the expectation and hope surrounding our Lord’s first coming into the world and the anticipation of His second coming to judge the living and the dead.
The light again signifies Christ, the Light of the world. Some modern day adaptions include a white candle placed in the middle of the wreath, which represents Christ and is lit on Christmas Eve. Another tradition is to replace the three purple and one rose candles with four white candles, which will be lit throughout Christmas season
