O'Callaghan's argument is as follows: • According to O'Callaghan, in line 2 "after the ⲱ, the ⲁ suggested by the editors seems inadmissible. The traces of the facsimile are too uncertain to allow a satisfactory reading, even though one comes to discover the left vertical stroke and the peculiar descending contour of a ⲛ similar to that of line 4." By reading a nu after the omega, O'Callaghan was able to reconstruct the words [α]υτων η [καρδια], which could be matched with a passage in Mark's gospel. • O'Callaghan pointed out that the combination of letters
ννησ in line 4 may be part of the word Γε
ννησαρετ . • O'Callaghan argued that the spacing before the word
και ("and") 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". The reasons why most scholars have rejected O'Callaghan's arguments include the following: • Several of the letters read or reconstructed by O'Callaghan are highly debatable (especially the nu in line 2). • The spacing before the word
και ("and") proposed as a paragraph break may not be indicative of anything. • In papyri spacings of this width can be also found within words (Pap. Bodmer XXIV, plate 26; in Qumran in fragment 4Q122). • Other examples in the Qumran texts show that the word
και ("and") usually was separated with spacings – and this has nothing to do with the text's structure (as proposed by O'Callaghan). • The sequence
ννησ can be also found in the word εγε
ννησεν ("begot"), a very common word used in biblical genealogies and the reconstruction suggested by the original editor. • To make 7Q5 'fit' Mark 6:52-53, the words επι την γην ("to the land") in line 4, which are found in Mark 6:53, would have to be considered as being omitted from 7Q5 in order to fit into its column. However, this omission is found in no extant manuscripts of Mark's Gospel. • 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. Anachronism found in Mark's Gospel • Another problem with identifying 7Q5 as Mark's gospel is the argument that Mark 12:13–17 may potentially contain a reference to
Vespasian's Fiscus Judaicus imposed in 71 AD, meaning the gospel had to be written after this date, while 7Q5 dates to before 50 AD. == Significance ==
