Which one is the pope?

I don't know why I even notice or pay attention but the bishops have this one locked down. I am pretty sure there is a first turn checkmate for them. So, going to war wasn't the best idea.

1. Where are the little children pieces and the clergy that are sooooo attached to them?
2. I guess the bishop pieces can disappear and reappear, when they are in danger of being captured, on different boards randomly.
