If everyone attending your Christmas party is of the same religious persuasion as you, you could always consider adding a celebration of Advent to your festivities. You can get your family or guests involved with readings and devotionals as you light the advent candles. If your celebration is on Christmas Eve, you can conclude with the lighting of the center Christ candle, celebrating His birth. For a short explanation of Advent with some suggestions for celebrating it in your home, check out the Christmas Traditions Blog.
