This volume (though expensive!) is now probably the most up to date analysis of earliest evidence about the state and transmission of NT writings in the second century CE. Given the limitations of our evidence, scholars are required to make the best inferences they can. This volume provides essential resources in doing so, and largely shows that we can with some confidence posit that the NT writings, essentially as we know them, were copied for both ecclesial and private reading.At the SBL, two other scholars told me in passing that they were reviewing the book, one of which were Brice Jones, and the other one I cannot remember.
Speaking of the early text of the NT, one issue that I have described as controversial is whether the text of Codex Vaticanus – the single manuscript which is probably closest to the text of NA28 (96% similarity in the Catholic Letters) – goes back to a recension or rather reflects a strict transmission.
In Eldon Epp's “The Twentieth-Century Interlude in New Testament Textual Criticism,” in Studies in the Theory and Method of New Testament Textual Criticism (ed. E. J. Epp and G. D. Fee; Grand Rapids: Eerdmans, 1993), 103, he noted that with the publication of P75, the issue of whether the “Neutral” (or Alexandrian) text or text type is the result of a recension or of a strict transmission was not resolved, but pushed back into the second century.
Now that I read through Eldon Epp's new chapter on "Textual Clusters: Their Past and Future" in the second edition of The Text of the New Testament in Contemporary Research. Essays on the Status Questionis, 544, I note a small, but important shift:
That finding [of P75] was sufficient to render invalid any view of B as a mid-fourth century recension; rather, the B-text cluster had been moved back in time a century and a half and strongly solidified. Also, the long history of NT textual recensions, in the technical sense, clearly had been terminated.Now I heard that Brent Nongbri has just proposed (at the SBL in Chicago) that P75 might be dated to the fifth century(!), so perhaps the recension issue will see a revival. On the other hand, there are many other papyri attesting to a strict text (á la Alands), and, as Epp puts it (p. 553), "the B-cluster is supported also by third- and fourth-century pastristic sources, and with impressive secondary Greek and versional members," so I don't know.
Update: I might have misunderstood Nongbri's proposal; it might have been the fourth century. We will have to wait for the publication.
