UPDATE: Kingdom Grace provides an important forum to add to this discussion in her post, I Am Not as Smart as Ben.
Ben Witherington III has begun a series taking apart Viola and Barna’s Pagan Christianity. Whether you are a lover or hater of PC, it’s well worth the read. (I would suggest that BWIII is not a neutral party in this discussion – but his scholarship cannot be argued easily.)
Frank Viola is a sharp person, but neither he nor George Barna really interact in this book with the scholarly literature that would call into question their strident claims and theses. They are arguing a particular case, and so they largely cite sources that support their case, for example Robert Banks’ work on Pauline house churches comes in for heavy usage. Their claim to present us with bare historical fact and to stand always on the Biblical high ground needs to be seen for what it is from the outset— good and powerful rhetoric meant to warm the cockles of the hearts of all who affirm Sola Scriptura, but when one actually examines some of the major claims closely, they will not stand close and critical scrutiny.
