How does an agnostic approach a sacred text like the Christian Bible's New Testament? If one is not ideologically committed to giving the New Testament special treatment, the principles underlying its interpretation are the same as for as any other historically important writings. However, as a manifesto for a new religion, the New Testament has been filtered through a period of oral transmission and doctrinal battles between groups advocating rival interpretations, and one must bear this in mind when reading it. Here is a summary of the analytical techniques by which an agnostic evaluates the historical accuracy of the narrative parts of religious writings like the New Testament. How do we judge which parts of the account are likely false and which parts are likely true?
The New Testament writers are often explicitly concerned with correct doctrine: arguments between different factions are mentioned and even play out explicitly between different books. Also, answers to doctrinal questions are given, often in the gospels as quotes attributed directly to Jesus. One may suspect that such quotations are fabricated when we find an early authoritative pronouncement from Jesus on a matter that later became a topic of dispute. Why was there any argument if the Lord had spoken? For example, Mark 7:15 attributes to Jesus a renunciation of the Jewish law: "it is not what goes into a man that defiles him, but what comes out". If that were a genuine pillar of his teaching, how could such acrimonious disputes have arisen later between Pauline and Jewish Christians over keeping the law?
This criterion can be generalized to cast doubt on the authenticity of any material that relates more to the issues important to the emerging Christian movement than to issues important to Jews in Galilee in the early first century.
If you know what points a given writer was trying to emphasize, then you may suspect fabrication when a later account of events contains extra detail, missing from earlier accounts, that validates those points more strongly. After all, if the earlier writer shared the same viewpoint, why would he have left out such satisfying material?
A simple example is the walking on water story, which in Mark's gospel only involves Jesus (Mark 6:48) but in Matthew's gospel has been expanded to include Peter, who gets a memorable lesson in the importance of faith (Matthew 14:29). If Mark's gospel is truly based on the memoirs of one of the apostles or any other reliable source, it is hard to believe that Peter's involvement could have been forgotten, so one suspects that the story has undergone some improvement. A bigger example is the nativity story, which occurs in Matthew and Luke, but is not mentioned by Mark. Again, if Mark's gospel is based on reliable sources surely he would have known about his Lord's miraculous birth: why would he have left out something so spectacularly supportive of Jesus's authority? It is natural to suspect that the nativity is a later confabulation. An even bigger example is the resurrection story itself, which is missing from the earliest versions of Mark's gospel (which end at Mark 16:8).
Possible complications to this logic are (1) the earlier writer may not have known about the extra detail; and (2) the earlier writer may not have shared the later writer's view of what is important. In the case of Mark's lack of a nativity story, neither of these is plausible. The nativity story is so spectacular that if it is true then it must have spread with knowledge of Jesus and his teachings. Any reliable informant must have known it. And clearly the writer of Mark wanted to maximize the power of Jesus's teachings, so he would not have neglected to tell the nativity story if he had known it. There is much more evidence that the nativity story is a later contribution: (a) the fact that it goes unmentioned by Paul as well as Mark, (b) Mark's gospel shows some signs of adoptionism: the now-heretical belief that the spirit of God possessed Jesus for the period of his ministry then returned to heaven; (c) invention of birth-stories is common (see standard patterns of myth below).
One can also apply this criterion to sayings, in the converse of the "principle of dissimilarity" discussed below. People tend to attribute well-known wise sayings to famous figures that they revere. So if a writer attributes a wise saying or idea that was commonplace at the time of writing to one of his heroes (or an obviously foolish remark to one of his enemies), this alone is not very strong evidence that the figure actually originated it. For example, the saying "Those who are strong have no need of a physician, but those who are ill do", attributed to Jesus in Mark 2:17, was a well-known Cynic proverb. Its appearance in the gospel is therefore not strong evidence that Jesus actually said such a thing.
If a writer reports something that runs contrary to what he would naturally believe or want to believe, then he probably didn't make it up: it is more likely to be factual, or at least handed down from a respected authority. We can apply this principle to reports of sayings and events.
We have mentioned above that the attribution of standard sayings to a respected figure is a typical form of legend-building, and is accordingly suspect. On the other hand, if a weird and unusual saying ("dissimilar" from standard lore) is attributed to a hero, or a wise saying to an enemy, then there is good reason to take the attribution seriously. For example, this form of the criterion of dissimilarity could be used by Christian apologists to support the authenticity of Jesus's final words on the cross, "My god, my god, why have you left me behind?" This cry is downbeat and theologically difficult (after all, the Son is not supposed to be separable from the rest of the Trinity, and he should know that what is happening is a wonderful act of divine atonement for all mankind). Christian apologists can argue that surely this quote must be authentic, since if someone were inventing a messianic death cry they would concoct something more edifying, such as "Now I take the sin of the world onto myself!".
Following similar logic, if a writer reports an event whose significance goes against his usual viewpoint (is "unpalatable" to him), his report is more likely to be factual or from overwhelming authority. This argument is used by Christian apologists who note that Jesus's empty tomb was reported to have been discovered by women. If women had generally low status at the time, surely no-one with a new religion to sell would have invented a story that gave them such a crucial role. Another example is the baptism of Jesus by John: surely no Jesus-follower would have made up a story that had his hero seeking absolution from the leader of a rival religious movement.
On its own, the principle of the plausibility of the contrarian is not a very powerful tool for determining factuality. The problem is that when a writer reports some unpalatable event or saying, his reluctance may have been overwhelmed not by its authenticity but because it was authoritatively handed down from a previous stage of the movement to which it was not unpalatable but exactly what they wanted to believe. For example, Christ's final words would not have been invented by a second-century Christian, but could easily have been invented by adoptionist first-century believers, who believed (as the writer of Mark's gospel may have) that the Christ-spirit left Jesus to die on the cross, and returned to heaven. That quotation then became fossilized in the canon of sacred writings, unpalatable but unavoidable to later writers, and nevertheless fictional.
Because arguments from silence are often presented incompetently, they have a bad reputation. Some people think that all arguments from silence are wrong in principle, and that if they can pin that label on an argument, they have refuted it. Obviously this is wrong. But it is true that arguments from silence need to be buttressed with reasons why, under the circumstances, silence implies absence.
An example of a good argument from silence is the complete absence from all canonical scripture (or historically relevant non-canonical writings) of any statement of Jesus having been married. Does this mean that he never took a wife? Presumably if he had, this would have been noted and remembered and reported. The absence of evidence for a wife surely counts as evidence of absence.
From the agnostic viewpoint miracles and prophecy are not such a crucial feature of the scriptures. An over-eager atheist might argue that their mere presence calls into question the factuality of the texts in their entirety. Some literalist Christians might naively treat them as evidence for the divinity of Jesus. However, there is plenty of room between naive literalism and hyper-sceptical atheism.
Some literalists invoke "prophecy" to assign early dates to texts, earlier than events mentioned in them. From the agnostic point of view this is not reasonable. Correct written prophecy is not a phenomenon for which we have any independent evidence. To invoke it for this purpose is essentially to assume that Jesus is divine in order to assemble an argument for his divinity. Our philosophy is to apply conventional methods of analysis to the text first, and see if the divinity of Jesus emerges naturally from that analysis. If it were necessary to assume that scripture is divinely inspired in order to reach that conclusion, that would mean there is no persuasive argument to bring an unbeliever to belief.
Even if, on similar grounds, we set aside the spectacular miracle stories of the gospels as fable, the rest still constitutes a formidable set of religious propositions, of great importance if true. The key point is the central miracle, the resurrection of Christ. If one denies a priori that this could be true, then it is pointless to discuss the rest. From the agnostic viewpoint, then, one must judge the validity of the accounts of the resurrection using the techniques described above, without assuming its truth or impossibility. The crucial question then is: do the gospels provide strong enough evidence to make a persuasive case that these extraordinary events actually occurred?
