So I just finished reading Zealot by Reza Aslan and I'm now reading it again. Based on what the book says, Christianity seemed to be formed by a Zealot movement in Palestine. It was many centuries later where the Roman Empire adopted the religion to rid of paganism.
It seems like, based on the book, that the New Testament of the bible is Roman Empire propaganda, rewritten for Roman citizens.
Which makes me wonder, is Christianity, technically Roman mythology or Greek mythology?
PS. I'm a layman to Christian and Roman history.
The New Testament was written long before Christianity became the religion of the Roman empire and was written in the eastern half of the empire (not Rome) so it's not really Roman mythology.
But some parts of the New Testament are certainly written for educated Roman citizens. For example, if you compare the gospel of Mark (probably written in Syria, around the year 70) to the gospel of Luke, you can see that Luke has many more Greek literary tropes, which educated Romans would have known. Scholars believe that Luke adapted Mark, changing the writing style to make it more literary and Roman and less Semitic. Pretty much all of the NT was written for non-Jews, probably, because it almost always translates and explains Jewish religious concepts. In that sense, then, it was "rewritten for Roman citizens," as you say, but it also is a natively Semitic story, full of quotations from the Hebrew bible, and originally about a group of Judeans.
