Gospels, not certain. Paul: so far, the consesus is either 50 AD or 55.
The Pre Pauline Creed is important, and dates to 30-35 AD. This seems to rule out the theory the Ressurection was a late addition.
Well, that is interesting.
I’m ashamed to say that I wasn’t aware of this.
It’s interesting stuff! Its formulaic nature may indicate that it was the product of considerable thought over time, but it certainly pre-dates 1 Corinthians and suggests an early date for a conception of the resurrection.
Just to fill in detail here - 1 Cor is one of the undisputed Pauline letters.
The “creed” could be of any date before 1 Cor (Passover, 55AD), but of course must also express the gospel that Paul had believed - unless we suppose that somehow the back-story he knew to have no evidence slowly came to seem true to him. And his conversion is usually dated at 33-36.
That would make a belief sufficient to convert Paul from antagonism convincing to a skeptical inhabitant of Jerusalem within 3-6 years of the event. That’s legend on steroids!
