Christmas is associated with the custom of decorating the Christmas tree that adorns the interiors of churches, homes, in addition to city squares and other public places. The coniferous tree is a symbol of life, rebirth, longevity and fertility in many cultures. A decorated fir or spruce tree has become Europe’s most recognizable symbol of Christmas. The living tree has also become a Christian symbol of Christ as the source of life. But also some Christmas tree decorations have their own symbolic meanings, although not always recognized today: for example, the star placed on top of the tree was supposed to show the way back home from far away, the lights point to Christ, who is the light of the world, the angels are the ones who take care of the household, the paper chains reminded people about the enslavement of sin from which Jesus frees us… In modern culture, however, presents placed under the Christmas tree seem to be more important. And yet, they are also a foreshadowing of the gifts of Heaven. It is worth to look at the Christmas tree remembering about its symbolic value, which Christian culture carries, to better and more fruitfully live the joyful mystery of Christmas.
