The Question of the Greek New Testament

[Minimalist]

There are 7 works attributed to Paul that even critical scholars like Bart Ehrman don't dispute. He wrote at least those 7 letters, and about that there is almost no doubt.

There are 7 works attributed to Paul (key word there "attributed") which were stylistically written by the same author - as opposed to all the others which are blatant forgeries.
The question is, was that author named "Paul" or was he a literary construct just like 'jesus.' 

Again, paul's epistles burst on the scene with Marcion's canon c 140 AD.  But Marcion was a heretic and even a generation letter c 160 Origen did not use the name "paul" in any of his writings.  This is more than a curiosity.
