Another Greek of the same name
Hmmm, I would dispute that simply because it takes for granted certain things, like for example, the existance of Peter, and presupposes that Christianity developed more or less as it is claimed in the new testament; i.e. first in Jerusalem and neighboring regions, then spreading North and West.
I'm not much of a scholar of this, but I was always under the impression that it was the immigration of Jews to greece, and the subsequent mistranslating of the Torah into Greek that led to the writing of the gospels, some 100 years or so after the destruction of the temple. I have also heard that it may have been refugee Jews who felt betrayed and abandoned by their god who gave rise to the idea of the messiah who was betrayed and abandoned by the people. That is to say, the emotional shock of the Diaspora led some Jews to reinterpret their religion, in the context of the other religions they were exposed to, and thus arises christianity.
Just a theory though, I don't know much evidence to support it, other than timeline coincidences, and the fact that the Gospels are clearly of greek origin. And of course, if large numbers of Jews were leaving Israel pre-diaspora, this could have happened at any time.
It seems to me that both Jesus and the apostles are purely fictitious in nature. The disciples, including Peter, are like stock characters in a Platonic dialogue; they are there to be foils for Jesus. Paul is the only apostle who seems like a real person. Even if he isn't, I think its much more likely that there was a historical equivalent to Paul rather than Peter. (of course, I take Paul's account of events with a great deal of skepticism, given his published attitude toward lying) Speculation of course, documents are sketchy, and lots of religions (perhaps all) have fictitious accounts of there origins which obscure the reality of the situation.
Hmm, well...
Whether or not Jesus, Peter and Paul were actually prophets of God (clearly I don't believe they were) there
is evidence (however flawed) that they existed and led the church, and no evidence that they didn't.
In addition to the Gospels and the Epistles, Josephus, Suetonius and Tacitus all mention Jesus or his followers. (The reference in Josephus was for some centuries faked by zealous Christian scribes to provide evidence of Jesus' divinity; the original version refers to little more than Jesus' existence as a religious figure.) When they mention Christians, they always refer to them as followers of a specific individual, not as adherents of a particular doctrine - which implies that Jesus the person was more than mythological.
As for timeline, the Septuagint was written about two hundred years before the Common Era, not "100 years after the destruction of the Temple." The best evidence we have as to its place of origin says that it was created in Egypt, not Greece.
Internal evidence in the Gospel of Mark indicates that it was probably written about 70 CE, about the time of the destruction of Jerusalem, or even before it. Most scholars believe that the Gospel of Mark was based on an even earlier source, dubbed "Q." This would mean that the beginning of Christianity was an event in itself, not a response to the destruction of Judaea.
Although there were Jewish communities in Greece and Rome, the great centers of Jewish life outside Judaea were Egypt and Mesopotamia, south and east, not northwest.
The "messiah who was betrayed and abandoned by the people" is not a Jewish concept. It is purely Christian...or perhaps one should say gentile. The passage in Isaiah that is pointed to as evidence of the "betrayed and abandoned Messiah" is actually misinterpreted. In the original Hebrew, it is clear that the "man of sorrows" is a metaphor for the Jewish People as a whole, not for one man. However, the human scapegoat
is a tradition of many other religions of the Near East - the cults of Tammuz and Dionysos Zagreus, for instance. This makes it more likely that this aspect originated in non-Jewish communities that converted to Christianity, not Jewish communities that evolved into Christians.
Also, the Roman exile was not the first time the Jewish community had been uprooted from its homeland. The Babylonian exile and the destruction of the First Temple (the one destroyed by the Romans was the second) were even more traumatic, and they led to the writings of many of the prophets, but not to the creation of an entirely new faith.
