“The lighting of an Advent wreath during the Advent season is a Christian ceremony which has come down to us from about the time of Martin Luther. As before the birth of Christ the light of prophecy concerning His advent and His redemptive work became brighter and brighter, so the nearer we come in the church year to the feast of His nativity, the greater the amount of light from the Advent wreath. This ceremony is helpful for recalling, discussing, and teaching the significance of Advent.”
-An excerpt from?Ceremony and Celebration, in which Rev. Paul H.D. Lang?describes the theological significance and historic, confessional Lutheran position on liturgy, ritual, and ceremony.
