I'm confused. I read your link. It seems to favor my side that early creedal statements were geniune reflections of the first Christians beliefs "possibly within weeks" of the cross.
The way Paul writes about the sect makes clear he believed this was the creed Christians were preaching before his conversion; and he claims that the original apostles confirmed this to him years later, and he could hardly have been making that up, as then he’d have been exposed the moment anyone checked this with them. So the Corinthian Creed, at least verses 3-5, definitely existed and was the central “gospel” Christians were preaching in the early 30s A.D. That’s definitely no later than a few years after the purported death of Jesus. And since the sect’s formation only makes sense in light of this being its seminal and distinguishing message, it must have been formulated in the very first weeks of the movement.
John, Ehrman is top atheist / agnostic scholar right now who doesn't believe the resurrection happened. That's why I say that puts him in your camp.
Here's my problem:
4.) The tomb was empty.
Why was no body ever found when those in power desperately needed it to stamp out this threat to their authority.
5.) The disciples experienced seeing what they believed and said were appearances of the resurrected Jesus.
What could account for these appearances that made many people believe they were seeing the risen Jesus?
7.) The resurrection was the central message.
If the resurrection was fake, how could it start and flourish in the very city where the man died?
8.) The disciples preached the message of Jesus’ resurrection in Jerusalem.
If all the locals knew this was fake, why make this your central message?
10.) Orthodox Jews who believed in Christ made Sunday their primary day of worship.
Orthodox Jews are known as unbelievably attached to their traditions that has lasted for thousands of years and survived many attempts to eradicate, like Hitler. What in the world would cause them to abandon the Sabbath and make Sunday their day of worship, other than Jesus being resurrected on Sunday?
I'm open to plausible explanations for these established facts
