The use of evergreen trees to symbolize eternal life in Christian tradition dates back as far as the ancient Hebrew culture and stands as a reminder to this day.  With bark that protects from fire damage, insulated needles that obtain water, and a color that lasts through the toughest of winters, the evergreen is a spectacle of nature.  During the middle ages, missionaries that were preaching to the German and Slavic people believed that the Incarnation proclaimed Christ's lordship over natural symbols such as the evergreen that had previously been used for the worship of pagan gods, and that symbols such as these could be converted and redeemed for the glory of God.  During the Renaissance, evergreen trees served as a symbol of the "tree of paradise", being decorated traditionally with apples which represented the forbidden fruit, and wafers representing the Eucharist and redemption.  These trees were eventually placed in households and the apples and wafers were replaced by other ornaments and decorations.  The custom became popular throughout the 17th and 18th centuries, but was met with disapproval by some clergy members.  One of which being Lutheran minister Johann von Dannhauer, who contended that the symbol distracted people from the true evergreen tree, Jesus Christ.  Eventually candles were added to the trees to represent families or individuals, the predecessor to our modern day lights and ornaments.  
The evergreen trees however, were not originally associated with gift giving or "presents" as we now know them.  One of the earliest thought influences to Christmas presents was the Roman tradition of gift giving during the winter solstice.  When it became Christian tradition to celebrate Christmas instead of the winter solstice, the tradition of gift giving slowly died off.  ENTER Saint Nicholas, or who we now call "Santa".  Saint Nicolas was a Bishop of Myra in the 4th century.  He was known for taking care of children, being generous to the poor and giving gifts.  And he did this as an act of selflessness and service to God.  This spirit of giving soon became common practice in many different areas of the world as part of the Christmas tradition, and has evolved into our modern day Christmas celebrations.   
When Saint Nicholas, Bishop of Myra gave gifts to children, he was said to have been accompanied by helpers, who would help decide whether or not a child was deserving of a gift that year based on their behavior.  This is where the modern western culture gets it's concept of Santa; the jolly fat man in the red suit with a list of naughty and nice.  There are a lot of different variations of Santa Clause throughout the world that have evolved from the story of Saint Nicholas, but all of their tales are similar; they tell of one man's gift giving and selfless love for others.  With culture continuing to push the story of Saint Nicholas farther away from God and more towards commercialization and an expectation of toys and presents, many Christians find themselves wondering how to incorporate Santa into their story of Christmas and Jesus for their children.  Sadly there are more and more Christians that are trying to figure out how to fit Christ into their story of Christmas as well.  It seems that society has pitted Jesus and Santa against each other, and for Christians, this is a struggle.  But it doesn't have to be.  The Crossmas Tree is not intended to negate the concept of Santa, in fact Santa can fit into the story of God's redemption for humanity through the birth of our Savior.  Saint Nicholas of Myra gave selflessly to others, and that is the true spirit of gift giving.  He also knew why he did what he did, and who it was that he served; The Living God. 
The celebration of Christmas for your family and what that includes is ultimately your decision.  My prayer however, is that The Crossmas Tree helps you to remember that Christmas is not about what you get, but what you give.  And that our giving is not only a service to God and His kingdom, but a reflection of God's love, and the gifting of salvation through His Son, Jesus Christ.  May you and your family be blessed this Christmas season!
