Here’s an interesting twist to the standard argument explaining why we have so many gospels all with different accounts of Jesus.
Different eyewitnesses report different details about the same event, it is said, and that explains the multiple “reports” of Jesus’ arrest, trial, death, resurrection, etc. But check the following by a scholar of Socrates:
The trial rapidly became so notorious that a number of Apologies of Socrates were written soon afterwards, and at least one prosecution speech purporting to be that of Anytus. If the object had been to report the actual speech or speeches Socrates himself gave in the course of the trial, there would have been no need for more than one or two such publications, and all the rest would have been redundant. The fact that so many versions of Socrates’ defence speeches were written strongly suggests that the authors were not reporters of historical truth, but were concerned to write what, in their opinion, Socrates could or should have said – which is what characterizes the whole genre of Socratic writings that sprang up in the decades following Socrates’ trial and death.
