Paul was alive during the time of the apostles and actually met with Peter and some others at the Council of Jerusalem. Peter might have met Paul earlier too maybe when he was first there? James was the head of the church in Jerusalem and he was Jesus' brother.Very little is actually known about the man Jesus, there are some public documents written at the time that record his existence, i.e. births, deaths & marriages, other than that with regards to his preaching the oldest doc available was written about 100years after his death and then there was a whole bunch dated to around 300AD.
Jesus was a wandering preacher, he spoke in parables and anecdotes, he never wrote anything down as far as we are aware of, so all the information regarding what he said was paraphrased by others and likely carried on through oral history before it was written down.
I do think there is some glorification going on in the bible, this is not to say that Jesus himself was not a great man, but I do believe to some degree he was appropriated as a figurehead by christianity to drive a bigger agenda, even though those documenting the writings may not have been aware of the inherent biases.
Take Paul for example, firstly he never was an apostle, all the others were long dead before he was even born, he spent the first half of his life hunting down and killing christians, then on the road to Damascus he had an epiphany and did a complete 180, becoming probably the most famous "Born Again" Christian, now it's likely that he bypassed that middle ground and suddenly he was pushing the christion cause with the same zealotry that he was supressing it in the past.
It is only after this time that the movement really made ground and I think it was around 400AD that the first bible was ratified and a board of directors effectively selected what teachings and scriptures were representative of christianity, we all know of Mathew, Mark, Luke and John cause their writings took centre stage, what about the other 8 guys (gals?). Another interesting point, after the death of Judas, which is still one of the unsolved mysteries, the other 11 disciples needed to elect a 12th, Matthias was chosen, obviously he had been in the outer group for a while and was well versed enough to take on the promotion, but when the bible was ratified, the above board also decided that the others had made a mistake in choosing Matthias and decided that Paul should be placed in the 12th position forever more.
Now that brings into question, what else did they think wasn't right and did they also take the opportunity to correct these things before going to print?
So with regard to this statement, you first need to question who actually wrote this, in what context and were they driving their own agenda, did they have investments in the industry, own a chain of mills, involved in grain production, was it the prototype for Big Pharma health marketing, ahh another conspiracy?
