Hi..... again. Let me try............
I am an HJer. Now, to your question.
I don't know which year Jesus died, but in any case I think that the oral traditions concerning his mission and death spread outwards in all directions.
I don't know how or when Historical Jesus became 'Theological Jesus', but I'll bet that Paul and others used Jesus's life, mission and death to build his own idea of a religion upon. Paul only needed the Hellenised name and Hellenised Title of Jesus for that, and definitely pushed his life, actions and sayings into the background. So he wouldn't have been too excited about Jesus shrines. See how he puts his own title of apostle ahead of Jesus's titles of Teacher, Healer etc in 1 Cor 12-18.
And so, my answer is that Paul and others wanted the foci of the faith where they wanted them......
Any good?
Another version is that Jesus never died, and Joseph of Arimathea got him off that cross, wounds and all, alive. You already know of the stories about Gaul, and Cornwall, and Kashmir.
What makes you think that Paul's Christ is the same as the Jesus of Nazareth? We don't know who the gospel writers were and didn't Paul warn of false Christs?
