I was very curious to see how the Luther museum treated the narrative of Luther's life. The traditional Protestant story I heard growing up portrays the Catholics of his time as something akin to demons, and Luther as some sort of angelic crusader against them. Meanwhile, the revisionist version I heard in college focused more on the political entities involved, emphasizing the fact that Luther's movement was only successful because powerful people decided they could use him for their own ends.
As usual with polar extremes of a story, neither is wholly true, but I don't think I really understood the middle ground of Luther's life until I went through the museum. It carefully presents the beginning of his struggle with the papacy, and we see that he is indeed no divine being. However, Pope Leo and Archbishop Albrecht do come across as pretty horrible people (mostly through primary sources, and some of their own words) focused on their own wealth and reputations above all else. Certainly, Luther would have been just another John Hus if the elector of Saxony hadn't stepped into the fray, leading to the inevitable Protestant-Catholic wars and feuds which would continue for centuries, but I don't think that tarnishes the moment of Luther's big decision to criticize the biggest institution in the world essentially by himself. The Pope had legions of theologians to support him - Luther went up against them alone because he was convinced that the truth did not allow him to do otherwise.
The museum portrays Luther as an extremely conflicted, brilliant man desirous of absolute truth in a world full of compromises and hypocrites. Once the theological conflict became a physical conflict, Luther wondered if it would have been better if he'd just been quiet. Yet he knew that he had to speak the truth as God gave him to see the truth. Despite decrying the Catholic practice of veneration of saints as idolatry, he continued to hold the Virgin Mary in high regard for the rest of his life. Not a simple character, that Luther. If you can't tell, I highly recommend the museum to anyone vaguely interested in church history.
