Really? NONE? Not one?
Peter will be interested in learning that. As will John and Matthew. Though I know plenty of contemporary liberal NT "scholars" like to dispute their authorship, at least recognize that tradition assigns the authorship of these Gospels to Jesus' disciples.
Likewise though the authorship or James and Jude are in dispute, they are generally attributed to two of Jesus' brothers. I myself wouldn't want to press too hard for that to be true of Jude, but the argument for James seems thoroughly reasonable and highly compelling.
Let's see.... that was Matthew, John, James, Jude, and Peter. 5 NT writers other than Paul, responsible for 10 of the 27 books of the NT. Already that is more non-Pauline material than you allow for and I haven't even included Mark and Luke/Acts yet. And as a matter of fact, if you were to count pages, in my Bible the works of Paul (assuming that they are all actually by Paul, for the same people who argue against Matthew and John being actually written by one of Jesus' disciples also argue that most of the letters that bear Paul's name were written by others as well) account for only 92 of the 354 pages (only 26%) of the New Testament. So, may I suggest that before you go making assertions about Paul writing 75% of the NT, that you do some fact-checking first.
Putting my cards on the table, I will say that Jesus is based on a historical real person. He may have claimed some godhood. Plenty of people do this right from Achilles to Mike Travasser, actually hundreds of thousands of people claimed this.
Mike Travasser of Strong City has 50 adherents, 50 diciples, including 12 virgin girls (who remain virgins despite his actions apparently, even the 14 year olds).
We can discount Mike as being divine. He's simply a peadophile with a religious hook and preying on the gullible.
If he died tommorow and he was living in a slightly different era, his diciples would write of his miracles, of which there have been many. All un-filmed, all in the past. He cant actually pop a miracle out on demand. He says to the film crews , "thou shalt not test the lord thy God". Pretty much because as soon as you test him, he fails. In abundance.
Christianity really only got on a roll a century after Jesus was supposed to have lived. Nobody alive saw the miracles. They simply beleived the one single account. The Bible.
It offered paradise which was fairly unique, it brought in a old-new concept...."Hell" and it certainly brought hell on earth for anyone in opposition as the romans battling with christian terrorism finally submitted to "Jesus's mercy".
With the thousands of scribes and historans and scholars faced with a
Literal God on Earth, alive in their times and openly wanting people to see and record everything, we are left with 7 people,( the fisherman, the quack, the council-worker, Jesus's best mates,(and how did they learn to write!)) to record in their 90's in an era where people lived to their 50's tales of amazement and wonder.
The sort of stuff that today you would laugh off in a heartbeat.And the sort of stuff that is taken as "Gospel"
