Five hundred years ago this October (2017), a young professor in an obscure German University through the marvellous new invention of printing changed the world and rocked the Church and the Vatican to its core. This priest professor, Martin Luther, had a problem with the way money was tied in with religion, and his document, consisting of Ninety Five Theses, opened the floodgates of anger at a Church enriching itself on the superstitious beliefs of the poor. Luther had begun a movement that changed a world in which it was virtually impossible not to believe in God to a world full of questions about the meaning of life and truth. His solution was that only the Bible had the answers, but this became a source of controversy and eventually led to a divided Europe and wars of religion.Since then a new, modern, scientific world caused many to question all of religion, until in today’s secular society doubt about God is almost inescapable. In the gospel, Luther found a God he never ceased to proclaim and this book tells his story. It goes on to analyse the challenge he put to the world of his time and endeavours to show that he challenges today’s world and churches too.
