Authorship of the letters that Paul wrote are in fact not under scrutiny
by scholars. What is the source of your information MorningStar,
One letter is under debate, the letter to the Hebrews.
I have never assumed Paul wrote Hebrews, nor does it matter.
Unless of course you are referring to letters outside of the New Testament such as 3 Corinthians. Which is of course beyond the
boundaries of Talk Jesus.
Further, I might also ask whether you have read the book of Acts which Luke penned along with the Gospel of Luke.
Acts contains an eye witness account of Paul and his teachings.
Paul's interaction with Peter, the Church in Jerusalem, Paul's
commission by the pillars of the church in Jerusalem.
Missionary journeys, etc.
Opinions? What opinions?
Yes,
everything Paul wrote has come under question at more than one time in history, and by quite a few historians.
Considering all the extravagant situations that Paul was supposed to be involved in, such as his early persecution of Christians, his supernatural conversion, his miraculous release from prison (Acts 16:26), and being pursued by hundreds and hundreds of soldiers and horsemen (Acts 23:23), being stranded from a shipwreck (Acts 27) and supposedly founding several churches around the Mediterranean, being a Roman citizen, and self claimed Pharisee, he fails to make it into any credible historical texts
of that time. Considering the hundreds of well known historians, (and that time period being one of the most well documented in historical record), he was completely overlooked by Josephus, Pliny, and other well known historians.
Although in modern times, even Thomas Jefferson wrote that Paul was the "first corrupter of the doctrines of Jesus" and if you look at the discrepancies of the teachings, he was quite correct.
It is also claimed by scholars that his writings were simply a product of pseudepigraphical transcription.
What has become Paul's greatest hurdle for historicity is that it appears his stories were a 'compilation' so to speak of Apollonius of Tyana, and even the works of Josephus. He appears to be a mish-mash created character that the early RC Church wanted to promulgate in order to give credibility to their agenda.
I'm sure you are ware that the book of Apollonius of Tyana vs. Paul of Tarsus was a huge controversy in the Christian world because of the vast and detailed similarities with Paul in the bible. Like Paul, Apollonius was educated in Tarsus, knew Ephesus, and he cast out demons and even raised people from the dead. (Not that people raising from the dead was a rare event in those times considering hundreds were raised at the same time Jesus was resurrected.) So, it is quite possible these stories are SO similar because Apollonius
was Paul, or that Paul was 'plagiarized' from Apollonius. I mean if you think more than second about it, the names are quite similar linguistically.
Apollonius was thought to be a well respected person in those times, who caused a substantial movement, so the church later concocted his history to match and agree with their agenda and give the impression that he was a follower of their Christ. It appears they may have done the same with Paul.
BTW, stories about 'eye witness accounts' are only as good as how well we know the witnesses, and their credibility. In Paul's case, we know virtually nothing as a concrete fact.
