In 2010, with his dog Mitzpah by his side, Rabbi Wittenberg walked from his grandfather"s Frankfurt synagogue to his own, in Finchley, carrying the Ner Tamid - its Eternal Light - to co-shine forever in the newly built synagogue in North London. A film crew covered most of the trip and even Mitzpah wrote a blog, describing his experiences on the epic journey. Colleagues and friends accompanied them for some of the route and their discussions also contributed insights into the spiritual, social and political concerns that occupied the Rabbi"s thoughts as he continued to meet many people along the way. Readers of Jonathan Wittenberg"s other books already know the humane, insightful and often profound observations and thoughts that preoccupy him. Walking with the Light: From Frankfurt to Finchley will both delight and stimulate a whole new audience. Few religious writers can combine the humour and incidence of walking across northern Europe with cogent arguments for moral justice, a process perhaps to accept Europe"s horrific past and show why a belief that tolerance and true understanding of the past is the only way to improve the future.
