We are seeing the first example of an unabashed JEDP adherent.
And why not? Rome has sanctioned the JEDP , among other liberal revisionism, for decades in her own NAB Bible's notes, even on the Vatican web site. http://www.vatican.va/archive/ENG0839/__P8.HTM
Paul’s letters were written over a period of about fifteen years(51 AD to 66AD) (after he had himself been a Christian for about fifteen years), and sent to churches and individuals far removed from one another. How, then, did these thirteen come together? The short answer is that we do not know; the evidence is too slight to be certain. In some cases Paul himself ordered limited circulation (Col. 4:16). Good arguments have been advanced in support of the view that Ephesians was first written as a general circular letter for believers in Ephesus and in neighbouring towns and cities, a general letter covering more specific ones such as Colossians and Philemon (and perhaps Philippians).
The first concrete list that has come down to us is the list of ten Pauline letters (excluding the Pastorals) compiled by Marcion (the leader of an unorthodox Christian movement about 140). Some scholars argue that this was the first time any such list was put together. But this is highly unlikely. Only a tiny fraction of written material from late antiquity has come down to us, and Marcion’s list is valuable primarily as evidence that larger, more orthodox lists were probably already circulating. It was the practice of such pseudo-Christian leaders to adapt Christian literature to their own needs. Marcion excluded all of the OT and most of the New; even of the gospels he preserved only a mutilated edition of Luke.
Others have argued that Paul’s letters were first brought together shortly after AD 90, fifty years before Marcion. Some devoted follower of Paul, spurred on by the publication of Acts (shortly before 90, on this view), pulled the extant Pauline letters together. But it is far more likely that Acts was published much earlier, about 61 or 62, and difficult to see why the collection of at least some of Paul’s writings would have had to wait for that event anyway. There is strong evidence that several of Paul’s letters are cited in the early apostolic fathers (especially Clement of Rome; c. 96). More importantly, 2 Pet. 3:16 refers to the way Paul writes ‘in all his letters’, an expression which, though it does not necessarily embrace precisely the thirteen canonical letters that have come down to us, certainly presupposes that there is common knowledge of a circulating body of Pauline correspondence. Although the weight of contemporary scholarship favours a late date for 2 Peter, substantial reasons can be adduced for a publication date as early as 64 or 65.
