Dr Gardner says: "In summary, this is a scholarly book that has good material, but it suffers from an academic penchant to spend too much time offering other people's research."
The reason for this is that Wells has done no original research of his own, and therefore has none to offer the reader.
He comes to the subject as an amateur, with his mind already made up. He is interested in the work of genuine NT scholars only in so far as they can be quote-mined [often out of context] to support his own procrustean views. Since this book was published he has published two further books - The Jesus Legend and The Jesus Myth [both of which I first read in MS draft] - in which he has made a few minor concessions to his critics: but they really amount to very little.
He still to this day considers that Paul believed in a Jesus who had lived and died unknown a century or more earlier than history teaches: the Gospel Jesus - whom he considers a different person - he has more recently come to regard as a composite figure based in part on Q, but largely on imaginative ruminations on the OT and Wisdom literature.
The 'Third Quest' has completely passed him by; a beached whale on the dry sands of 19th century rationalism.
