Tim and Lydia McGrew on archaeological support for the New Testament

I have linked to the McGrews' essay from the Blackwell Companion to Natural Theology.

The role of such naturalism as a motivating factor in the work of the form
critics is often explicit, but as an argument against a more traditional
position it suffers from the obvious drawback of circularity. Consequently,
form critics have typically supported their conclusion of late dating of the
gospels and Acts by pointing to ostensible anachronisms and errors of
detail that show the authors to have been, not eyewitnesses, but creative
and tendentious redactors writing at a substantial remove from the events
they are purportedly recording.






Unquestionably, if we examine the gospels with a literary lens of sufficient
resolving power, we find that they contain material belonging to various
literary types: logia, parables,pronouncement stories, speeches, and so
forth. To recognize this fact is not to make any concession on the point of
interest to us here. And anyone who has read much biblical criticism
knows that the form and redaction critics often command much real
scholarship and sometimes display astonishing imagination. But there are
good reasons for dismissing the sweeping negative conclusions of form
criticism regarding the authenticity and reliability of the narratives. There
are no independent textual traditions preserving the allegedly earliest
forms; one must discern them in the existing text, and in many cases
the layers are visible only when the text is viewed with eyes of
form-critical faith. There is a substantial and growing body of
evidence that thegospels were indeed written by eyewitnesses or by
those with access to eyewitnesses. And the conjectures of the form
critics regarding the dating and accuracy of the New Testament writings
have repeatedly been shown by scholars in other fields to be embarrassing
blunders.


A few examples may help to illustrate the latter point. In the early 20th
century,the French critic Alfred Loisy dismissed the description in the fourth
gospel (John 5:2) of the pool of Bethesda as having five porches. This,
Loisy said, was a literary alteration or addition designed to represent the
five books of the law which Jesus had come to fulfill. On the basis of such
reasoning, and in harmony with the late dating advocated in the previous
century by the Tübingen scholar Ferdinand Christian Baur, Loisy set the
date for the composition of the gospel at some time after A.D. 150.
Excavations of the pool of Bethesda in 1956 revealed that it was located
where John said it was, bounded on the sides with four colonnades and
spanned across the middle by a fifth (Leon-Dufour, 1967, p. 67; Jeremias,
1966, pp. 36-38). As E. M. Blaiklock says, “No further comment is
necessary” (Blaiklock, 1983, p. 65).


Archaeology has not been kind to literary criticism of the gospels and Acts.
The discovery in Caesarea Maritima in 1961 of an inscription bearing
Pilate’s name and title, the discovery of a boundary stone of the emperor
Claudius bearing the name of Sergius Paulus (cf. Acts 13:7), the very
recent discovery of the Pool of Siloam (John 9) from the time of Jesus,
and numerous other discoveries indicate a level of accuracy incompatible
with the picture of the development of the gospels as an accretion of legend
over the course of two or more generations. Our point is not that these
discoveries demonstrate the accuracy of all other portions of the gospels;
rather, it is the commonsense principle that authors who have been shown
to be accurate in matters that we can check against existing independent
evidence deserve, within reasonable bounds, the benefit of the doubt when
they speak of matters of putative public fact that we cannot at present verify
independently. Several such discoveries also indicate that the author of the
gospel of John was familiar with Jerusalem prior to its destruction, a point
that directly addresses the attempt to place a very late date on the text.
