In Mormonism, members of the LDS Church believe in the birth of Christ. Many members have traditions in the church, like singing carols door to door, do a secret santa, (give a gift to someone in a way like leaving a gift on the porch) visit sick and afflicted people, both old and young, and old. Some members also read out loud stories that were shared by members of the Quorum of the Twelve Apostles (one of them is now President of the Church). Two books that I know of that are read every year are "Christmas Oranges," and "A Christmas Dress for Ellen." Both of these stories are really heart touching and are great to read out loud to the family.
Leaders and members of the Church believe not so much in getting, but more into giving. I have been a witness countless times in which members gave homemade treats, gift cards, thank you cards, and other gifts to other members. I also witnessed many times deacons, priests, and elders have taken their time and energy in shoveling snow, cutting wood, and doing services to others and for even the whole community. I have felt the spirit many times, in both seeing this, and doing service myself.
Members of the LDS Church believe in the birth of Christ (also called the Nativity), how he was lain in a manger, (fancy name for a feeding trough) and the new star shining brightly over him. This is what Christmas is about; celebrating the birth of Christ and giving gifts and doing good services to your neighbors. It is also a time to relax, spend time with your family, and take a break from worldly problems. Sadly though, in this day and age, many people don't care much about the Nativity, the miracles that occurred, and many people even don't say, "Merry Christmas." Instead, the replace it with, "Merry xmas," or, "Happy Holidays!" It happens all around us, mainly on shop windows, signs overhead, and even in movies and television. Many people also ignore the meaning of Christmas, like serving others and giving gifts. Instead, they spend much time, energy, and money in meaningless things, like lights contests, black friday, (really big one, because of the violence and profanity that goes on there. I have never went to a black friday opening, and I know people that have and their experiences.) and anything that could draw away the spirit.
