“We hope to celebrate this anniversary without hiding the problematic side, the dark side of Martin Luther,” says Rev Johannes Block, pastor of the Evangelical City and Parish Church of St. Mary’s in Wittenberg, Germany, where Luther himself preached hundreds and hundreds of sermons in the 16th century. “The Reformation said you are responsible for yourself,” he continued. “Everybody is responsible for his faith. It’s a step of democracy. Everybody is equal in the church.”
