[The_Rorschach]

Well, just to throw a couple pennies. Paul, pre-name change, did meet Christ, and was viewed by the Chruch at large as an authority on doctrine. . .So I believe Romans has some validity.

However, if you REALLY want to quibble. Most non-conservative (biblically not politically) oriented theologians believe that the book of John was written by multiple authors in the name of John. The synoptic gospels (Mark, Matthew and Luke) are treated as a group, because they agree closely. The Gospel of John is treated separately, as are the writings of St. Paul, because of their discussion of the nature of Jesus and the criteria for salvation, as opposed to the life and times of the Man himself.
