That's a good point, but the problem is that non-Christian first-century Jewish writers did the same thing with Old Testament texts on other subjects. Matthew and Paul were indeed inspired in some way, we know that, but their methods were not unusual for first-century Jews. So, on the one hand, what they did with the Old Testament is a big departure from what we would consider fair or accurate exegesis, and if we want to argue God inspired them to take these passages out of context and twist them into a messianic storyline, then we should acknowledge that uninspired writers of the same era did the same thing on different subjects, presumably without divine assistance.
We've gotten a bit off track, so I'm going to backtrack to a more general argument and rely here on Christian Smith's
The Bible Made Impossible, which talks about "biblicism," a term he defines using the 10 general assumptions below. Not all biblicists believe all 10, but if you find yourself agreeing with most of these, then Smith would say you use a biblicist approach to scripture:
1. Divine writing – The Bible "consists of and is identical with God's very own words written inerrantly in human language."
2. Total representation – The Bible contains everything God has to say to humans and is the exclusive mode of divine communication.
3. Complete coverage – "The divine will about all of the issues relevant to Christian belief and life are contained in the Bible."
4. Democratic perspicuity – "Any reasonably intelligent person can read the Bible in his or her own language and correctly understand the plain meaning of the text."
5. Commonsense hermeneutics – The best way to read the Bible is in its "explicit, plain, most obvious, literal sense."
6. Solo Scriptura – Not to be confused with sol
a scriptura, this means the Bible can be understood without reliance on creeds, tradition or other hermeneutical frameworks. In other words, "theological formulations can be built up directly out of the Bible from scratch."
7. Internal harmony – On any given subject, all the relevant passages of the Bible are unified and consistent.
8. Universal applicability – The teachings of the Bible are "universally valid for all Christians at every other time, unless explicitly revoked by a subsequent teaching."
9. Inductive method – "All matters of Christian belief and practice can be learned by sitting down with the Bible and piecing together through careful study the clear 'biblical' truths it teaches."
10. Handbook model – The affirmations of the Bible "comprise something like a handbook or textbook for Christian belief and living, a compendium of divine and therefore inerrant teachings on a full array of subjects – including science, economics, health, politics and romance."
His argument is that this cannot be true because, if it were, Christians would be able to agree a whole lot more on what the Bible actually says. He calls it "pervasive interpretive pluralism." Essentially, if it were so easy to figure out the teachings of the Bible through relying on the literal text, how come no one can agree on what those teachings are? The failure of more than relatively small numbers of Christians – including evangelical Christians who subscribe to biblicist doctrines – to agree on any significant point in the Bible (how we should worship, the nature of justification and atonement, the relationship of Christians to the world, the existence and use of charismatic gifts, etc.) is a
prima facie nullification of the idea that the Bible is internally consistent, easy to understand or meant to be a handbook for Christian living.
Why and how, we might ask, would the Bible be so easily misread by so many believers if, as biblicism believes, it is divine, inerrant, internally harmonious, perspicuous [clearly expressed and easily understood] and intent on revealing infallible truth to humankind? ... If the truth of the Bible is really sufficiently understandable to the ordinary reader, then why do so many of them – and countless biblically and theologically trained scholars besides – find it impossible to agree on what the truth is? This response [that a small number of us have it right and the rest are biased, deceived or dishonest] places a huge burden on the bad intentions, biased interests or poor scholarly skills of Christian Bible readers across two millennia – a burden the evidence cannot sustain.
Regarding the "original autographs are infallible" argument, he says – much better than I managed (bold added, italics original):
What good does that do the actual Christian believers who do not possess the original documents – that is, nearly all Christians in church history – who want and need to understand Christian truth? Nothing. All that actually does is formally build a logically protective, unfalsifiable wall around a theory. But that proves completely unhelpful for the more pressing task of actually knowing what is true, real, wise and good. People standing on a sinking ship in the middle of the ocean are not helped one bit by the in-fact-totally-correct observation that if they were on another ship they would not be sinking. Neither are Christians reading the actual Bible that they possess helped in any way by the idea that they would have greater clarity of understanding if they could only read the original autographs of the original manuscripts of the first scriptural writings. The lost-original-autographs explanation is not necessarily false. It is simply useless and irrelevant. It does not address and explain the present problem in a satisfying or constructive way.
Like Smith and Peter Enns, who has focused more on the increasing incompatibility of literal biblicism with scientific discovery, I think the church needs a better way to read the Bible. It doesn't mean we strip it of divine authority, but it does mean we stop transporting modernist sensibilities onto premodern texts and use the culture and context in which those texts were produced to lead us into a deeper understanding of what God is doing in this world and a better sense of how we should respond to that.
Just my $.02 anyway.
