Archeological verification of the historical events recounted by Sacred Scripture does not require Catholic faith.
While I agree that some of Wyatt's claims seem to be unfounded, others appear to have been very solid, and I believe that he did a great service overall to help the faith, especially belief in the historicity of Sacred Scripture (that is being called into question even by "Trad" priests like Fr. Paul Robinson, with the blessings of SSPX) ... even if Wyatt doesn't have the faith himself.
So many millions have lost the faith due to the attacks against the inerrancy and credibility of Sacred Scripture ... and people like Fr. P Robinson are part of the problem.
