I want to stress independent. I’m looking for a summary of scholarship, and I hope it doesn’t become a debate. First, I am drawing primarily upon a staff report, Who Wrote the Bible?
In many theological discussions, it often boils down to “God said…”, “Jesus said…”, or “Jesus did…”. But we don’t know what Jesus said or did, we only know what’s written about him. And if two sources write much of the same things but are known to have collaborated somehow, it really doesn’t strengthen the historical evidence at all.
I want to know how many independent, original (as far as possible) sources of Jesus’ existence we have. I realize that these may not be absolutely, positively, independent, but scholarly opinion suggests that they probably are.
I’m temporarily ignoring such dubious sources, which certainly are not primary, as Josephus, Pliny, Tacitus, etc.
Source #1 – The Synoptic books of Matthew, Mark, and Luke, all of which probably drew upon Q or each other.
Source #2 – John, who did not draw upon Q or the Synoptics?
Source #3 – Paul, who did not draw upon Q, the Synoptics, or anything else we know about?
I’m aware that these names are probably not the actual apostles, and have been assigned for convenience, not because of real authorship.
If I am correct, we have only three independent sources of Jesus, and it’s possible (how likely?) that the later ones had at least passing knowledge, perhaps oral history, of the earlier ones.
Which might reduce the body of evidence of Jesus – his existence, works, and life – to only one source, and one that is only available to us indirectly.
What say our scholars?
