jmfcst, when dealing with ancient historians it's important to remember that none of them are all that trustworthy in the way you and I would define 'trustworthy'. Tacitus isn't the worst offender by far, but he still is prety worthless as a chief witness for the defense. In general anything beyond direct eyewitness acounts from antiquity can be disregarded if it isn't corroborated by other sources and/or archaeological findings.
But it is corroborated! That’s my point - If nonChristian (both Roman and Jewish) accounts are wrong, then why does Acts have the same objections being presented by nonbelievers as indicated in both the Roman and Jewish records?!
Doesn’t the fact that we have 3 differing historical groups (Christian/Roman/Jewish), who have no reason to agree on this subject, all agreeing on the nature of the argument, prove that these were indeed the arguments of that day?
I won't disagree with that. Just don't overtly rely on Tacitus alone in your argument. (Which is a bit on the trivial side, but that isn't that important.)
