How We Celebrate Christmas
by Wilhelm Beilstein
Christmas is to us Germans the most lovely and meaningful season of the year. From it, we gather inner strength and power from the eternal life force of our nature. Mother and child, family and kin are at its center. It is not limited to a day that swiftly passes, but rather it encompasses a long period of preparation and many mythic beings and customs. Despite many foreign influences, over the course of centuries it has remained an ancient German holiday, and its nature can only be understood within the territory of our people. Today, we have once again come to know the true meaning of our Christmas customs and traditions, freeing them from foreign names and influences (see the article in N.S.-Brief of December 1938). The following remarks will provide ideas and direction for organizing Christmas and Advent festivities.
