You bring John Dickson! I have read his book.
About Tacitus...
Even though the passage is authentic to Tacitus, it might be argued that Tacitus received his information about the origin of the Christian name from Christians themselves. This could be argued on six grounds: (1) Tacitus does not identify his source explicitly. (2) Tacitus anachronistically identifies Pilate as a procurator, when the proper title would have been prefect. (3) Tacitus refers to the founder of the name as 'Christus', while written records would presumably have used the name Jesus. (4) As meticulous as the Romans were, crucifixion records hardly went back nearly a century in time (the Annals being written c. 115 CE). (5) There is insufficient motive for Tacitus to research about this Christus in any detail, as the reference appears in Tacitus merely as an explanation of the origin of the name Christian, which in turn is being described only as an example of Nero's cruelty. (6) Finally, there would be no reason for Tacitus not to take the basic Christian story at face value, especially since the idea that they were of recent origin would correctly classify Christianity as a superstitio.
Suetonius - around 120AC - is the quote reliable?
