Here are some helpful links to aid any discussion. I'm not promoting the websites as being in agreement with all of the content but it might actually help anyone who wants to comment gain a general gist of what is being spokem about (so all of it can be up for critique/discussion etc).
This site presents the works that are said or believed to be credited to the historian going by the name Josephus.
www.earlyjewishwritings.com/josephus.html
This link might help any reader get more acquainted with the concept of and the relationship between Josephus and the NT books, much rather like we might use the "media" or newspapers to document historical facts during an important religious time period, remember wikipedia and such wasn't around lol..

Some of the arguements regarding Paulus/St Paul/Paul/Saul/saulus and their familiarities spread amongst the biblical and historical records (with the assumption both are 100% reliable which many "will" and "do" argue is NOT) might include some form of bias from whichever point of view the compiler/author writes from, this could be because the auuthor is Catholic, Islamic, Jewish or Atheist... so Im going to use the "multi-faith" option here and include some I have found that while do not neccessarilly follow my own beliefs or opinions (and Eisenman's lol) they might still show "doubt" as to Paul' identity or at the least add to the pool of clues that might otherwise raise those doubts.
I don't claim to be in agreement with all perspectives but when I said I'm not alone in my questioning of who Paul is as a general consensus it might otherwise be accepted on differing grounds (and levels of intellectual reasoning) show and share the conclusion that Paul as a charachter is not straightfoward and I think I can at least prove this single point:
This one is from a Catholic perspective (?), from Dr Taylor Marshall, asking wether Paul is indeed related to the Herodian dynasty by offering 7 proofs.

Next we have Robert Eisenman, mentioned earlier in this thread.

Next we have Douglas Tondo, an "evangelical" Christian attorney, who gives a detailed account of Paul from multiple perspectives, suggesting Paul/Saul' links to the Herod dynasty but offers a more prophetic account or of why Paul might fulfill the "Benjamite Wolf prophecy" amongst other details.

There seem to be quite a few sites dedicated to contradictions between Jesus and Paul.
But rather than offer the reader my choice or my bias can simply google search this area and see the overwhelming amount of sites and links to this area of study...(should they feel they want/need to including yes...Wikipedia and YouTube lol)
Here is a website (that for me not only was incredibly SL L O W W to load but required me to lose all my open tabs to exit from it!!) It might be better viewed on a computer and I include these links because it gives "authorative" (and widely accepted) information regarding the Sanhedrin, also for those who might find getting acquainted with this court system and it's protocols which certainly helps when reading about what is mentioned in the NT accounts (and in the witings of Josephus) ie the accounts of the trials of Jesus, Stephen,James and Paul etc..
Requirements for judges, including members fo the Sanhedrin.

What do Muslims make of Paul' credentials?
I don't quite know for sure but I suspect since he is not mentioned in the Quran, then he has no merit outside of his own letters? (any Muslims feel free to correct me if I have tis incorrect please)
