what christian religion does not celebrate christmas

There are several Christian denominations that do not celebrate Christmas as a religious holiday, including Jehovah's Witnesses, some branches of the Church of Christ, Scientist, and some non-denominational Christian groups. They believe that the celebration of Christmas as a religious holiday has become too commercialized and has strayed from its original purpose as a commemoration of the birth of Jesus Christ. Instead, they focus on other religious observances, such as Easter, which they consider to be the more important and central event in the Christian faith.
