Yes, Seventh-day Adventists do celebrate Christmas. Christmas is a time to commemorate the birth of Jesus Christ and to honor His teachings and example. Seventh-day Adventists have traditionally celebrated Christmas as a time to reflect on the love and sacrifice of Jesus Christ, as well as to reaffirm their faith in Him as their Lord and Savior. While some Seventh-day Adventists may choose to celebrate Christmas in a more secular or commercialized way, many still hold to the traditional Adventist values of simplicity, humility, and charity in their celebrations.
