This book is written as a lengthy reply to letters addressed to the author by one of his friends. It has two parts. The first deals with theological question on resurrection, eternal damnation and the end of times. In this first part, the author also briefly mentions the panic in Athens when Halley 's comet was due to arrive. In the second part, Ioakeim Spetsieris argues that even the atheist and the materialist are in reality deists and that the Communism of Christianity has very little to do with the materialistic communism.
