On Thursday of 4th Week, author, writer, broadcaster, Quaker and Humanist David Boulton will be speaking to the Oxford Atheist Society about his concept of a faith which is unashamedly spiritual, yet rejects the supernatural and embraces a secular society. This, in David Boulton's eyes, is the "republic of heaven". It is also the subject of his latest book, "The Trouble with God". David Boulton has written extensively on religion as well as politics, current affairs and history, including two books on the historical Jesus.
