Everything you need to know about Luther's teachings is presented concisely and clearly by Norbert Bolz. No contradictions are attributed to Luther, nor is there any reference to the temporal context of his statements. Instead, the focus is on the central components of Luther's doctrine. This doctrine is straightforward. Therefore, this book about him will be understandable for everyone. Norbert Bolz positions Luther against the sentimental humanitarianism of our time. There is no sharper critic of do-goodism than Luther. The great Danish Protestant of the 19th century, Søren Kierkegaard, speaks of Christian fortification in this context. He hits the nail on the head when he says that Luther teaches a faith for adults. And this is precisely what the Protestant Church needs today. The significant Luther Year 2017 provides a fitting occasion for this major rethinking.
