Updated 5 hours after posting to expand Schweitzer quote.
The approach I like to take is one I learned from the way historians (certainly many of them at any rate) investigate other topics, whether in modern, medieval or ancient times.
I have used the example of Alexander the Great before, so for convenience I use it again here. It’s a safe bet to say that the existence and conquering career of Alexander is a “fact of history”. We have primary evidence from his own time still surviving (e.g. coins) and testifying to his place in history. We have much other evidence for major cultural, economic and political changes throughout the Middle East that are most cogently explained as the result of his conquests. So when we read secondary sources about him we have supporting knowledge that assures us that these sources are about someone real. We might call this sort of supporting knowledge “external controls” that we can bring to our reading of the secondary sources.
The problem with studying Christian origins as if Jesus himself were the historical founder of Christianity is that we have no similar controls to support the New Testament narratives. This is why, after discussing the problems with using Josephus and Tacitus as evidence for the historical Jesus, Albert Schweitzer wrote:
In reality, however, these writers [those arguing for the historicity of Jesus against mythicists] are faced with the enormous problem that strictly speaking absolutely nothing can be proved by evidence from the past, but can only be shown to be more or less probable. Moreover, in the case of Jesus, the theoretical reservations are even greater because all the reports about him go back to the one source of tradition, early Christianity itself, and there are no data available in Jewish or Gentile secular history which could be used as controls. Thus the degree of certainty cannot even by raised so high as positive probability. (From page 402 of The Quest of the Historical Jesus, 2001, by Albert Schweitzer.)
So what is the safest way to approach the Gospel narratives about Jesus? Continue reading “Another way to study Christian origins”
