Quote: Because there is a structure, style, vocabulary, and subject matter that are Pauline.
No. You have no idea what "pauline" is because we do not have the originals. We have a group of 4-7 epistles (depending on whom you talk to) that are considered "authentic." But what does that mean?
If you sat down at your desk and wrote a series of letters in the name of Shlomo and a couple of hundred years later someone edited them and wrote a few more in the name of Shlomo scholars writing later - after the fear of being burned at the stake by fanatic believers had evaporated - scholars would probably be able to sort out the edits and the forgeries from your original letters based on style. But all they would be able to do is attribute them to "Shlomo" because none of them would have ever heard of "Danny."
That's your problem with this paul shit. You take way too much on faith.
