At any rate, I highlight this new [or non-]criterion of authenticity because it appears to me that this is the central approach to Jesus research undergirding Allison's book. Indeed, he says as much:
Recurrent attestation yields much more than [Tom] Holmén imagines, for not all the regularly attested themes and motifs are nonspecific and cursory. I offer this book as the proof. Nevertheless, I agree with Holmén to the extent that recurrent attestation is not sufficient unto itself. It supplies as I hope to show, much more than a minimalist foundation. It is not, however, everything. As I stated earlier, although we may well begin by asking, "What are our general impressions?" we need not end there. (20; my emphasis)
If the number of pages is any indication (nearly 600), Constructing Jesus amply demonstrates at the very least that recurrent attestation is a first word in a very long conversation.
