This book was written in 1930, and although its message is eternal and universal, I would say that the make-up of its potential readership in Britain today is very different to the one which existed when it was written. Britain is a much more multicultural nation and people are generally much more skeptical about religion than they used to be.
Frank Morison was the pseudonym of an English journalist called Albert Henry Moss (born 1881 died 1950), who sought to analyse and pick holes in the Resurrection story focussing on the disappearance of Jesus' body from his tomb after his crucifixion. He treats the sources of information that he has in an almost forensic manner and I for one enjoyed revisiting these passages and building up a highly detailed picture from just a few verses of each gospel. Every word and clause is pored over and treated as an historical fact. He brings attention, not only on the key players (Jesus, Peter, Pilate etc) but also on the other minor players in the drama to show their contribution to the story. Morison also brings in other historical sources to justify the logic of the Christian story as presented in the gospels such as the unauthorised gospels and Josephus' history. I would have appreciated more footnotes to indicate the exact sources of what he was trying to convey.
I recall from my schooldays my head teacher talking to my class about ideas contained in this book. I commented that surely it was more important to reflect on what Jesus did and said rather than focus too much on the Resurrection. He said that the Resurrection story was absolutely key and if it were not true, then none of the other aspects of Christ's life and work would matter. This sounds to me like CS Lewis' trilemma that states that Jesus could only be "Lord, liar or lunatic". The Resurrection story is of course key because it is the fulfillment of the Word and so any analysis that gives weight to the historical veracity of the story is very helpful. Personally speaking, I have never had much problem believing it. Compared to Jesus' virgin birth and all the miracles He performed (including raising Lazarus from the dead), his own resurrection does not seem so unusually miraculous.
I have to say though that if you are of a skeptical frame of mind, don't have a basic religious faith or recognise the Bible as a historical document, then you probably will not be convinced by this book. Frank Morison's approach is based on close reading of the Bible and stating that the actions of all the players, major and minor, appear to be entirely rational and in keeping with the miracle of the Resurrection: and therefore, any of the alternative explanations that might disprove the Resurrection do not hold water. I do not think he really explains what he thinks actually happened but leaves the mystery as a mystery - which is ultimately a matter of faith.
