Amen. is a film that I think most Christians would find challenging and thought provoking. The film raises questions about the Christian's response to evil and about what happens when the church becomes more concerned with self-preservation than holding to its principles. The central character is Kurt Gerstein, a devout Lutheran of the Confessing Church, who is also an SS officer. Gerstein is in large part responsible for developing Zyklon-B used to exterminate the Jews. Upon learning about the true purpose of the chemical, Gerstein attempts to alert the world through his church officials and eventually through the Catholic Church only to discover closed doors. It is interesting to note the varied responses characters have throughout the film when confronted with evil--everything from denial of its existence to passive acceptance. The film is in large part not fictional. Kurt Gerstein was a historical figure and almost all of the events surrounding that character in this film are based on historical documents or testimony.
