I think Hannah set out to try to prove a highly imaginative fiction. He paints a colorful picture that would be the perfect topic for late night on the History Channel, but not something constructive to our study as Epicureans.
I did it again
. This time I was able to read approximately half of the book before I had to return the interlibrary loan.
This was a journey into esotericism derived from Epicurean philosophy!
To keep it short, according to how I understand his writings: Hannah argues that Jesus' message opens the door to the heavenly realms of the Epicurean Gods. Everyone can build an heavenly avatar by sending images of oneself to the heavenly realms and this avatar continues one's life after the earthly death.
Hannah's claim is highly speculative, but indeed, from an Epicurean point of view this answers questions about the Christian faith, how the resurrection and the afterlife can be packed in a sound thought structure.
His arguments can hardly be proven, but they raise interesting questions: How did the early Christians imagine how the afterlife works physically? What is "heaven"? There are many questions on early Christianity and even theologians may have no clear view on how to solve these issues.
