How is the pope similar to and different from other bishops?

He is considered to have more authority over the bishops, despite being chosen by them to become the Pope. He was also considered to be the only man who was able to communicate with God in Western society; during the late 70s, it was told that everyone could talk to God. As for similarities, the Pope is in the same Catholic religion, and same education/culture as the other bishops -- he is also very much more well-known to the public.
