But in late 1994, considerable publicity surrounded Carsten Peter Thiede‘s redating of the Magdalen papyrus to the last third of the 1st century, optimistically interpreted by journalists. His official article appeared in Zeitschrift für Papyrologie und Epigraphik the following year. The text for the layman was cowritten with Matthew d’Ancona and presented as The Jesus Papyrus, Weidenfeld & Nicolson, London, 1996. (also published as: Eyewitness to Jesus, 1996, New York: Doubleday). Thiede’s re-dating has generally been viewed with skepticism by established Biblical scholars.
Philip Comfort and David Barret in their book Text of the Earliest NT Greek Manuscripts argue for a more general date of 150-175 for the manuscript, and also for P4 and P67, which they argue came from the same code.. P4 was used as stuffing for the binding of “a codex of Philo, written in the later third century and found in a jar which had been walled up in a house at Coptos [in 250].” If P4 was part of this codex, then the codex may have been written roughly 100 year’s prior or earlier. Comfort and Barret also show that this P4/64/67 has affinities with a number of the late 2nd century papyri.
Comfort and Barret "tend to claim an earlier date for many manuscripts included in their volume than might be allowed by other palaeographers." The Novum Testamentum Graece, a standard reference for the Greek witnesses, lists P4 and P64/67 separately giving the former a date of the 3rd century, while the latter is assigned ca. 200. Most recently Charlesworth has concluded ‘that P64+67 and P4, though written by the same scribe, are not from the same … codex.’
