One day before the beginning of the Protestant Church Day 2017, the Giordano Bruno Stiftung (gbs) unveiled its action art "Die nackte Wahrheit über Martin Luther" ("The Naked Truth About Martin Luther") on Tuesday afternoon in Berlin. The sculpture, over four metres high, shows a naked Luther figure with an open coat. The inside of the coat depicts a quotation by philosopher Karl Jaspers: "Luther's advice against the Jews was precisely executed by Hitler". On the back you can read the reformer's anti-Semitic advice, including burning down synagogues, expropriation, and forced labour for Jews. The mobile sculpture "Der nackte Luther" will be on display at the Kirchentag in Berlin, Leipzig, and Wittenberg in the next few days, pointing to the dark sides of the reformer, which are all too often covered by a cloak of silence.
