A favorite childhood memory that stands very strong is the White Gift Service we would have every December on a Sunday evening at our church. My dad had constructed a large white cross. We would all bring canned goods or other food stuffs wrapped in simple white tissue paper.
After singing Christmas carols, and probably a short meditation, the lights would lower and all eyes would focus on the cross. Row by row we would move to the front and lay our white gifts at the foot of the cross. The food then was taken somewhere where there was a need. I don't remember that part, but I do remember the wonder of it, from a young child's perspective. Simple, but profound.
