Hi Omollo, interesting ideas....I disagree
But I bet you already knew I do, lol!
Omollo, these ideas all depend on discounting the most reliable historical evidence we have....the New Testament itself. Please, just take some time tonight, or tomorrow, maybe...read through the book of the Acts (of the Apostles), bearing in mind, it and the Gospel of St. Luke are actually one book, as I understand, but divided by tradition in order to keep the "Gospels" together in organizing the New Testament. There isn't a more reliable evidence regarding the beliefs and practices of the earliest christians than the New Testament and some other christian writings from the same time.
The following seems pretty clear to me when I read Acts. It continues the story after Jesus has resurrected, promised the coming of the Holy Spirit and ascended in Luke. Acts continues the story now by focussing on the christian community seeing as Christ has exited the scene as the "starring" character. You will notice very clearly that for some years, before the time that Peter is arrested and escapes prison and is forced to depart Jerusalem, it is not in question that he is the leader of the christian community there at all. It is he who preaches on pentecost, it is he who directs that Judas place be filled and leads the church to choosing st. Mathias by casting lots. It is before him that Ananias and saphira bring their gifts before they die etc etc. St. James simply isnt the main guide here until after Peter's departure, necessitated by Peter pulling a prison-break. St. Peter then moved to Antioch where he was Bishop. James ruled the Jerusalem church. But even then, it is Peter that God commands to open the church to gentiles through a vision. When a council is called to settle the fight about circumcision, the church meets in Jerusalem, rightly presided over by its leader, st James, but even so, it is Peter who settles the "debate" in that when he stands to speak, all debate ceases and does not resume thereafter. only "supporting evidence" is adduced by Paul and his companion in support of Peters teaching. Then st James considers the matter settled and proceeds to issue decrees in conformity thereto. After that, Acts mainly follows the activities of st Paul, the other apostles fall to the background.
About leading a banned movement in the capital? Well, I am honestly not sure about the issue. Someone had to lead that church, even if not Peter, some one else, because that church did in fact exist. It wasnt fictional. In fact it paid a really heavy price once Nero "founded" christian persecution as a Roman practice.
Jesus being God invented by Paul? Honestly, st Paul gets too much flack from JWs and Muslims, and too much credit. Personally, I find the most explicit words attributing Divinity to Jesus being in the Gospels, none of which were written by Paul. "The word was God" for example, which "became flesh", and "all things came to be through him", in John. St Thomas is recorded as exclaiming to Jesus "My Lord and my God!" The Gospels also attribute to Jesus qualities that were clearly divine. Even secular evidence from the 1st centuries describes christians externally as people who sang hymns to Christ "as to a god". Yes, Paul also says "he did not cling to his equality with God", but he is not the one who invents the notion. In fact, st Paul is a late-comer in christianity. Considering his background, he was MOST jewish of all the apostles, not just by blood, belief, regular lifestyle, but by career/training, he lost most for becoming christian. I just dont see what his motive would be in perverting christianity with paganism.
Another reason i dont accept the theory is that christian Jews were persecuted by other Jews for believing "blasphemous" things about Jesus and eventually kicked out of the synagogue altogether. Its clear that no early christian looked at Jesus like a regular prophet at all, he was much more to them all, without exception. And the Romans targetted them all, not just the jewish ones who were soon the minority after gentiles were allowed in. The perscutions continued sporadically for the next 3 centuries, even after a jewish segment identifying itself by its jewishness distinct from other christians had vanished.
