Martin Luther leaves for Worms. He has been summoned there by Church officials to be questioned about his writings. Church officials may be hoping that Luther's journey to Worms would be one of repentance but instead it takes on the character triumphal march.
At every town along the route Martin Luther is greeted by cheering crowds and he preaches to the people. It's a practical demonstration of just how popular Martin Luther's ideas have become among the German people.
