First, I think it is important to state at the outset that if you are considering reading this book you should read this book. In content, it is only about 160 actual pages and is very accessible. The prose is intelligent without being pretentious, giving the book a veneer of intellectual prowess without looking down on the reader. However, I think it is important that you do not only read this book, especially in the modern day. The book was written in 1996, but its arguments are lasting enough that they warrant comparison and contrast with modern scholarship.
First, there are (to me) clear epistemological problems with the book. It begins by criticizing historical-critical analysis techniques like the criterion of dissimilarity (the idea that we can be reasonably sure a statement is true if we can conclude the speaker is harmed by the utterance of it) or the anonymous sources (such as Q.) However, he acts as though this is the primary tool employed and that it alone is considered enough to believe something wholeheartedly. At the time, maybe this was true. I doubt it and it certainly does not seem to be the case today.
So, if we cannot trust scholarly tools like the criterion of dissimilarity, where do we get our information on the historical Jesus?
Bockmuehl believes we will find the answer in the Gospels of the New Testament, his argument is that extra-canonical gospels such as that of Timothy or Peter are too legendary, and likely too late, to serve as true historical sources. Thus, we must rely on the accounts of the 4 Gospels and some words by Flavius Josephus, the famous (and highly cited) ancient historian of Judaism. I think it may be beneficial to quote Bockmuehl at length. On page 20, discussing his epistemology, Bockmuehl says
"The Gospels were not written as novels, with the primary purpose of entertainment, but as evangels: that is to say, they are didactic and persuasive or apologetic works about events which transpired in their own time. This makes it even more likely that questions about the reliability and truth value of their sources were a prominent concern for the authors. All self-respecting Christian catechesis had to keep an eye on public credibility (cf. also C o l. 4.5f.; 1 Pet. 3.15f.). This is not to say that the Gospels do not contain elements which may strike the modem literary critic, and even the historian of ancient Judaism, as literary or theological embellishment. Nor is it to claim that they were intended as dispassionate historiography, even to the limited extent that Josephus's Jewish War was. But it is to assert as an appropriate rule of thumb that, unless there is good reason to think otherwise, the gospel accounts interpreted in their first-century contexts may be read as broadly reliable in what they do affirm about the life and teaching of Jesus."
I am not completely opposed to this and actually view the NT as an incredibly important primary source that passes many important tests on certain claims (multiple independent attestation and, yes, the criterion of dissimilarity, to name two) and I am even sympathetic to the idea that the authors would have some fidelity to accuracy as making claims of Jesus' being a 50 foot mech fighting a 50 foot mega Satan in the arena of Pontius Pilate would be so obviously fabricated as to harm the prospect of any converts. That said, I think Bockmuehl puts more stock in them than any historian has any reasonable right to. His faith is openly stated and I have no issue with him stating he takes the Gospels as mostly true but this is a huge claim that really begs the question.
Certain assumptions are baked into the text. No Gospel claiming Jesus was not the Son Of God and outright denying his resurrection, or otherwise in direct contradiction to the canon, would make the cut.
It is no historical secret that heterodox views are often destroyed. Thus, the Gospels should be used cautiously. I think Bockmuehl is a bit haphazard with his use of them and rarely deeply analyzes the reliability of the Gospels in and of themselves, only in relation to clearly inferior documents.
This book is actually something I read to balance out another book I recently revisited, "How Jesus Became God" by Bart Ehrman (another essential reading). A bible scholar I recently met said he thought Ehrman was "sloppy" and specifically recommended this book. While it was not explicitly stated this book would serve as a foil to Ehrman (in general, the conversation was not about "How Jesus became God" specifically) it was implied, and I think its true. Both books are concerned very much with the historical Jesus. Both are presented as a scholarly work, and neither should be denied this title. However, unlike Ehrman who critically analyzes the text for the most likely truth (at least as he sees it), Bockmuehl treats the canonical Gospels as presumptively reliable—not because they are demonstrably accurate, but because alternative sources are weaker.
In other words, Bockmuehl sees the gospels as relatively reliable and that's good enough. While others are interested in an absolute reliability, which I find at least the attempt—even if you want to say Ehrman or others failed to make compelling cases—to be more intellectually honest.
Just to give a concrete example of where I think this laxity causes problems is on page 53 where Bockmuehl says "Matthew and other early Christians identified Jesus with this Son of Man - a disputed identification but one which, I would argue, is implicit in Jesus' own words." However, we get Jesus "own words" from the Gospels and of course the authors of the Gospel accounts would make this at least implicit because early Christians would absolutely want to make this up. They would absolutely be motivated to insert polemical quotes with Messianic undertones. The fact that it isn't until John that we see clear indications of Jesus recognizing his own divinity is telling in itself, making quite the opposite conclusion stronger, in my opinion, but let's not get to far away from the review.
It is certainly true that we cannot really disprove the Gospels like we can prove scientific laws. So, as an intellectual work, I reiterate I still find it an important and worthwhile read. These weaknesses are not insurmountable. It is an upfront and clear epistemological belief. I find it incorrect, but it is not based on nothing. My real issue is actually with something else: the author’s conclusions.
In many of Bockmuehl's conclusions (and I mean some of the arguments he lays out and the claims based on them, not just the sections literally titled "Conclusion") the author eloquently blurs the lines of history and theology. I don't think this is nefarious or a sleight of hand, the author’s faith is stated at the outset as the opening chapter states that his job is to present a Jesus that is "historically probable and in plausible continuity with the faith of his first followers." (p.g. 8) The text ends (sans the epilogue and further reading) with the statement "[m]y argument in these pages has been that orthodox Christian faith, properly understood, is indeed a plausible and legitimate interpretation of that person. In other words, it is possible to join with integrity in the early church's conviction that "God has made this Jesus both Lord and Messiah" (p.g 167). So, his thesis is that Christianity is at least possible given the historical record.
Because this is his goal, I think he makes some strange statements. For example, in "Chapter One: Where Did Jesus Come From?" Bockmuehl says "Thus, the virginal conception of Jesus can be neither proved nor disproved. For those who do not reject the possibility of miracle, Christian belief in the virgin birth is certainly compatible with what can be known from history." In other words, this means a virginal birth is possible. I do not wish to restate the authors arguments, as you can read them for yourself and evaluate them, but I was certainly surprised by the content of them as I felt he was making a compelling case against a virginal birth and then settled on basically a 50/50 'who can say?' style conclusion while implying, in my view fairly heavily, the miracle version should be given preference
Another example is given on page 59 (which, actually, is in a "Conclusion" section.) Bockmuehl asks "Was Jesus the Messiah?" and goes on to say "The argument of this chapter has been to suggest that it is possible to answer with a qualified but unambiguous yes."
With statements like "Although the descendants of David were still being traced after the Exile, no Davidic ruler was ever to govern a sovereign Israel again" (p.g 45) and "it does not clearly describe one particular coming Messiah, but instead uses different metaphors to speak about human agents whom God will appoint (and "anoint') to bring about the coming redemption" (p.g 46), to show two examples I thought were compelling points against messianism and in fact, in many places, Bockmuehl makes concessions on the likelihood of messianism, I was very surprised by this clunkily worded "qualified but unambiguous yes." The contention I see between "qualified" and “unambiguous’ (though not literally mutually exclusive) notwithstanding, this is a much too powerful conclusion based on the evidence that feels like it really does not come out of anywhere. It is not even a 50/50 like the virginal birth, just a resounding yes! In these sections it does not feel like a scholar guided by a framework of faith, but a polemic grasping at straws to strain a conclusion that "might be" rather than one that "probably is."
In essence, this work is a quick sketch/overview of scholarship surrounding the historical Jesus sandwiched between a problematic epistemology and what I view as erroneous conclusions.
So, it is worthwhile as an introduction, compellingly written, but flawed as any book (especially one so short relative to the breadth of the topic) would be.
As a mini epilogue after a conclusion, I do want to say this review has been incredibly critical. That is because Bockmuehl is a compelling author that challenges the reader. Too many scholars put forth bland arguments in search of some unattainable neutrality. This book has a clear goal and identity, that should be commended and the arguments should be seriously dealt with. If this were a bad book, it would not warrant the time it took me to voice these concerns and that is why, despite my critiques, I have said throughout that you should read this book.
