Many people are familiar with Christmas Carols. During the Christmas season, we hear them played on the radio and in shopping malls. We hear them sung by pop stars. We hear them in the background of Christmas movies. I think Christmas carols are quite unique in this. We don’t hear Thanksgiving songs in malls or Easter Carols played on ordinary radio. Christmas carols have somehow survived the general purge of Christianity from public life. Several became part of the culture regardless of whether one actually believed their message.
