Jehovah's Witnesses don't celebrate Christmas for religious reasons. They believe that Christmas, as it is commonly celebrated today, is not in line with their beliefs and values. Specifically, they believe that Christmas has become too commercialized and has lost its religious significance. Additionally, they believe that the traditional Christmas symbols, such as Santa Claus, Christmas trees, and mistletoe, have pagan origins and are not in line with their interpretation of the Bible. For these reasons, Jehovah's Witnesses choose not to participate in Christmas celebrations.
