 Some add a fifth candle (white), known as the Christ Candle, in the middle of the wreath, to be lit on Christmas Eve or Day.The candles added to the wreath crown symbolise, in one interpretation, the great stages of salvation before the coming of the Messiah; the first is the symbol of the forgiveness granted to Adam and Eve, the second is the symbol of the faith of Abraham and of the patriarchs who believe in the gift of the Promised Land, the third is the symbol of the joy of David whose lineage does not stop and also testifies to his covenant with God, and the fourth and last candle is the symbol of the teaching of the prophets who announce a reign of justice and peace.Or they symbolise the four stages of human history; creation, the Incarnation, the redemption of sins, and the Last Judgment.
