1. The Pope thinks Faustus is a ghost.
Faustus and Mephastophilis have become invisible and they came to the Pope to play tricks on him. They started flinging the dishes around the room and the Pope and his friars got scared and though there is a ghost in the room, which is why he started crossing himself.
2. Faustus tells the Pope to stop crossing himself because the sign of the cross has no effect on Faustus.
Faustus realizes that religion is a fraud, especially when he didn't see God or knows of his existence, whereas the Devil is next to him playing tricks on mortals and taking their souls. He isn't frightened or offended by those symbols - he just knows that they are future and have no effect whatsoever.
Hello. You have not shown the advertisement to which this question refers, which makes it impossible to create an answer with accuracy.
Nazi propaganda was created to convince people to support the Nazi regime, to help the Nazi government achieve its goals and to publicize Nazi concepts regarding race and sovereignty. These advertisements were very effective during the Holocaust, when the Nazis were able to convince people about the problem of allowing Jews to live freely and how they should be exterminated.
