No surprise there (Wills’ dislike of the Church).
I’ve started reading What Paul Meant (WPM) by Wills and it’s a continuation of his sola scriptura philosophy in the other companion book, What Jesus Meant (WJM).
Of course, Wills does not see priests, bishops, popes, or sacraments mentioned in the Bible. To his credit, in WJM, his point of reference is ‘what Jesus said.’
WPM is a bit more interesting. I’ve run across his comparison of several accounts of Saul/Paul’s conversion. He points out how they vary. He conjectures that Paul’s conversion on the road to Damascus is a fake, by the evangelist Luke, as is Luke’s account of Paul’s journeys in Acts, which do not correspond to the statements in the most authentic of Paul’s books in the NT.
I have seen encyclopedic volumes on discrepancies in the Bible. So, I don’t know if Wills’ insights are original. Certainly, Wills echoes the dislikes of the Church that are so obvious in the writings of Raymond E. Brown. They both seem (to me) to eschew the magisterium and Tradition of the Church.
