Among the Dead Sea scrolls, 7Q5 is the designation for a small Greek papyrus fragment discovered in QumranCave 7 and dated before anyone claimed to be able to identify it by its style of script as likely having been written sometime between 50 B.C. and 50 A.D. The significance of this fragment is derived from an argument made by Spanish papyrologist Jose O'Callaghan in his work ¿Papiros neotestamentarios en la cueva 7 de Qumrân? in 1972, later reasserted and expanded by German scholar Carsten Peter Thiede in his work The Earliest Gospel Manuscript? in 1982. The assertion is that the previously unidentified 7Q5 is actually a fragment of the Gospel of Mark, chapter 6 verse 52-53. Some scholars have not been convinced by O'Callaghan's and Thiede's identification insisting it is "now virtually universally rejected". More recenlty, other scholars assert O'Callaghan's identification of 7Q5 is widely accepted as correct.
O'Callaghan's proposed identification
This shows the Greek text of Mark 6:52-53. Bold characters represent proposed identifications with characters from 7Q5:
ου γαρ
συνηκαν επι τοις αρτοις,
αλλ ην αυτων η καρδια πεπωρω-
μενη. και διαπερασαντες
ηλθον εις γεννησαρετ και
προσωρμισθησαν. και εξελ-
θοντων αυτων εκ του πλοιου ευθυς
επιγνοντες αυτον.
for they did not understand concerning the loaves but was their heart harden- ed. And crossing over they came unto Gennesaret and drew to the shore. And com- ing forth out of the boat immediately they recognized him.
Argument
The argument depends on these assumptions:
First, the combination of letters ννησ in line 4 may be part of the word Γεννησαρετ .
Secondly, the spacing before the word και suggests a paragraph break, which is consistent with the normative layout for Mark 6:52-53.
Furthermore, a computer search "using the most elaborate Greek texts... has failed to yield any text other than Mark 6:52-53 for the combination of letters identified by O'Callaghan et al. in 7Q5".
Several counterarguments exist.
The spacing before the word και proposed as a paragraph break may not be indicative of anything.
* In papyri spacings of this width can be also found within words.
* Other examples in the Qumran texts show that the word και usually was separated with spacings – and this has nothing to do with the text's structure.
The sequence ννησ can be also found in the word εγεννησεν , which was the original suggestion as to its identity.
* This suggestion was proposed by the authors of the fragment's first edition published in 1962.
* If so, the fragment likely would be part of a genealogy account.
Further counterarguments
To make the identification of the fragment with Mark 6:52-53, O'Callaghan had to substitute the letter δ with a τ in line 3, a substitution most scholars do not accept, although it is not without precedent in the ancient world.
In the line 4 the words επι την γην from Mark do not fit inside, because the length of line do not allow it, a variant which is not attested elsewhere.
The identification of the last letter in line 2 with nu does not fit into the pattern of this Greek letter as it is clearly written in line 4.
The computer search performed by Thiede assumed that all the disputed letter identifications made by O'Callaghan were correct, an assumption which is rejected by scholars.
* A similar search performed by scholar Daniel Wallace, which allowed other identifications for the disputed letters, found sixteen matches.
* A computer search performed with the undisputed letters of the fragment 7Q5 does not find the text Mk 6:52-53, because the undisputed letter τ in line 3 does not fit to this text.
Significance
If 7Q5 were identified as and was deposited in the cave at Qumran by 68 AD, it would become the earliest known fragment of the New Testament, predating P52 by at least some if not many decades. Since the amount of text in the manuscript is so small, even a confirmation of 7Q5 as Markan "might mean nothing more than that the contents of these few verses were already formalized, not necessarily that there was a manuscript of Mark's Gospel on hand". Since the entirety of the find in Cave 7 consists of fragments in Greek, it is possible that the contents of this cave are of a separate "Hellenized" library than the Hebrew texts found in the other caves. Additionally, as Robert Eisenman points out:
Most scholars agree that the scrolls were deposited in the cave in or around 68 AD, but often mistake this date... for the terminus ad quem for the deposit of the scrolls in the caves/cessation of Jewish habitation at the site, when it cannot be considered anything but the terminus a quo for both of these, i.e., not the latest but the earliest possible date for such a deposit and/or Jewish abandonment of the site. The actual terminus ad quem for both of these events, however difficult it may be to accept at first, is 136 AD.
So, for this is long after the currently accepted date range for the composition of Mark, according to Eisenman this would mean that even if it could be proved that 7Q5 is a Mark's fragment, an earlier composition date for the gospel could not be proved. Although the fragment has been analysed and dated paleographically, as Brent Nongbri said, the dating of a such small fragment on account of paleography is not appropriate.
Consequences
If one finds the missing link that conclusively determines the identity of 7Q5, different consequences can be foreseen. In the case where it is concluded in an absolute manner that it is a fragment of the Gospel of Mark, hypothetically dated from a date between 60s and 70s, it would coincide in having been written on a date before 73, year in which the community of Qumran was destroyed by the Romans. As the 7Q5 was dated between 50 BCE and 50 CE, it is feasible that - being of Mark - implies that there were written fragments of the Gospel chronologically close to the Historicity of Jesus. A blunt identification of 7Q5 as a fragment of the Gospel of Mark would represent an intellectual setback for those who conclude that the canonical gospels were drafted late, even after the second century, and for those who hypothesize that the Gospel accounts of Jesus are mythical.
