Aside from the real-versus-artificial debate, most people agree that buying and decorating a Christmas tree is a meaningful holiday custom. Now it can become a spiritual practice as well.
Some families have taken to blessing their Christmas trees before decorating them, remembering the part a tree played in the Garden of Eden and in our redemption, as the wood of Jesus' cross. Family Advent Customs (Liturgical Press) by Helen McLoughlin contains a tree-blessing prayer. But it doesn't have to be too complicated. Just thank God for the tree, which symbolizes everlasting life.
