I have seen varied criticisms of the methodology of New Testament scholars ranging from attacks on the criteria as unique to New Testament studies to claims that their application of historical methodology lacks the vigor or sophistication of that of classical historians. Some have dismissed their efforts as mere apologetics. While the limitations of such historical methodology should be explored, it has not been my experience that New Testament scholars are less zealous or sophisticated in their application of the tools of historical methodology. To the contrary, New Testament scholars seem to obsess about the use of formal methodology more than classical and other historians. Nor is it true that the tools employed by New Testament scholars are unique to their field and unemployed by classical and other historians. While many of the historians I have read do not employ these tools as often or with the rigor as do New Testaments scholars, there are many instances where these non-New Testament historians consider the number of sources (multiple attestation), the fit of the account with more established accounts (coherence), the inclusion of facts that are not well-suited to the author's goal (embarrassment), the impact of genre, and the "vividness" of accounts to evaluate historical probabilities.
Strauss' discussion of the historicity of Sinnicus is an example of a classical historian employing some of the same tools as New Testament histories on a questioned episode.
