Those darn Calvinists didn’t stop me...I got my pagan tree up in the living room...
Legend has it that Martin Luther began the tradition of decorating trees to celebrate Christmas. One crisp Christmas Eve, about the year 1500, he was walking through snow-covered woods and was struck by the beauty of a group of small evergreens. Their branches, dusted with snow, shimmered in the moonlight. When he got home, he set up a little fir tree indoors so he could share this story with his children. He decorated it with candles, which he lighted in honor of Christ's birth.
I heard that he was going home to his sick family from Christmas eve services.
