It is not too difficult to see why religious people objected to both the book and the film. Kazantzakis gives a portrait of Jesus as a man and not as a god. He is shown as a simple carpenter, practising his profession rather than seeking the road to salvation. As a human, he is subjected to the temptations that humans are subjected to, including, of course, sex. He is also subjected to the last temptation, that of leading a normal life and not being the Messiah, which nearly gets to him. If you are a Christian, you will have your own views, which will be coloured by your religion more than by literary considerations. For those of us who are not religious, the book is an interesting read but Jesus is just another fictitious character, even if, as has been said, he is based on Kazantzakis' own doubts, and there are more interesting fictitious characters.
