allegory

SPOILER
My husband and I ordered this from Netflix and thoroughly enjoyed it. It was a very rich story. It can be enjoyed on a simply narrative, literal level (except for the visionary ending, which was a little like the last scene in "Places in the Heart" where the dead come together in a harmonious resolution).
It seemed to me it also could be seen as allegorical, connected to the Gospels. Mary and Joseph (Maria and Josef) love each other but are childless. She announces she's pregnant and her husband is not the father of the child. He reacts as though she's been unfaithful, but she explains she hasn't. She then conceives a child who is "from the house of David." The child's birth brings about reconciliation and healing among factions of people who were in conflict before.
His birth brings about all kinds of harmonious plot conclusions. Because of the conditions of the birth, and the presence and witness of David, Josef and Horst are saved from the Russians. David, whom Maria and Josef thought might be the agent of their being arrested and executed, is responsible for Josef's deliverance. Horst has to be saved in order to deliver the baby. The man who tried to betray David is secretly shamed, but David doesn't betray him as a collaborator, so he goes along with the story about Horst.
At the very end
