In April 1945, Austrian psychiatrist Viktor Frankl emerged from the Nazi concentration camp at Dachau – the only member of his immediate family to survive the Holocaust.

Leading geneticist Steve Jones discusses the relationship between scientific enquiry and religious faith with Catholic journalist Mark Dowd. Steve Jones admits to his atheism - quoting with approval Napoleon's 'I have no need of that hypothesis' -- but is a fan of the Bible as 'a magnificent work of literature'. He also approves of many of Christ's pronouncements, but is averse to the Old Testament's 'violent god'. When asked if he is - unconsciously - making a case for New Testament Christianity, he responds 'Perhaps I am'.

The 12 steps which form the backbone of Alcoholics Anonymous only mention alcohol once, but God features four times, along with references to a higher power and spiritual awakening. But what does that mean in a country like Britain, where only around one in three people say they believe in God? Can the 12 steps work without a religious faith? And on the other hand, if a higher power is so central to recovery from alcoholism, why are there so many Christians with addiction problems?
