Not disputing what you said. But interesting that you postulate it was Pilate.
No record, such as in Acts, of Pilate’s coming to Jesus, like Paul on the Road to Damascus. Or he death.
I’m not postulating anything. I’m merely stating the facts as we know them.
- there were a very limited number of parties that could have related the details of that conversation. In fact the only two we know of for certain were Pilate and Christ. We might postulate, or assume an official like Pilate would not be alone with a prisoner without a guard or two. We can also speculate that given the sensitivity of the situation, Pilate may have had a close adviser or two more familiar with the local situation, customs etc.
- We do know that no Jew would have entered the palace.
- We know that somebody privy to that conversation found it worth remembering and memoriaizing in such a way that it found its way to the author of John’s Gospel. This party would not have been hostile to the Christian movement lest the account would have been buried.
Granted, everything beyond that is speculation, but somebody in that very limited audience of people found the exchange to be profound and worthy of recording for the ages.
