What are the motifs in Friedrich by Hans Peter Richter?

Destiny is a reoccurring idea in this story. Friedrich shows only those German Jews who accept their destiny is to suffer as God's chosen people scattered across the world, enduring suffering and death as a test of their faith, until such time as God sends his Messiah, returns them to the Land, and establishes his Kingdom. As the Nazis consolidate, power and issue more and more detailed and restrictive legislation about the Jews, they accept them fatalistically and comply.
