Pastor was preaching on the Transfiguration today, looking for some modern analogy. His weren't bad, but I think Transformers are a natural. Click. Twist. Rotate. Look, it's Jesus, but completely different. I picture lots of light being inside the original package, which shoots out in individual shafts as the unveiling takes place. Special FX. I think this part of the Bible seems stranger to adults than it does to kids.
Children's Church is easy to design that week. Draw a picture of Jesus transforming. Explain it. A lot of the boys would have him shooting at the devil - well, they want to have him shooting, but they've been around church long enough that you have to handle that very carefully. This armed Jesus upsets some people, but it's not very different from all those icons of St. Michael or St. George spearing a serpent, now, is it? The boys may actually be closer to Christian tradition in this.
