In this book after about 2000 years, I have proved that Jesus Chris were not a Jew rather he was Mandaean. Many people were doubtfull that Jesus was a Jew but they never knew if he was not what he was. In this book I show why there are such big differences between Judaism and Christianity like: 1- Why Sunday is holy-day and not Saturday? 2- Why they baptize and not circumcision? 3- Why not divorce in Christianity? 4- Why 300 years the symbol for Christianity was fish? 5- Where was Jesus for 30 years? 6- Who was John the Baptist? His name (mostly the real one) has appeared only in Persian translations and that has very important meaning while John has no meaning. And much much more which I have written in this book and I have much more in my head. In some universities of different countries which I have connected, their professors have started reading the book and discussed about it and may bring it up in their lecture and I have already given lecture in some universities in different countries. The subject has no expiry date and can be translated in any language. I have many writings on Philosophy History Society
