Went looking for Christmas Family Worship ideas and found this really beautiful one. It is for home use over the ten days prior to Christmas and would be nice for a family with school age or older children. Written by Douglas Jones of New Saint Andrews College (Moscow, Idaho) Requires an investment of time but doesn't seem to lengthy for a bedtime or dinner hour rite. Very rhythmic so even a younger sibling can engage.
Could also serve in a youth or college context for an Advent vigil.
