There is still the fact that Nero died in 68 A.D. and yet John seems not to have been exiled during that period. Vespasian was ruler following him. All writings mention Domitan as the emporer who exiled John, he didn't come to power before 70 A.D. None set a date prior to 70 A.D. so why not set a seperate post to challenge, Eusabias and Iraneneus and Clement and extra biblical history on when John was exiled to Patmos and when he came out of exile.
No separate post needed. Your comments here are imprecise and random, not reflecting at all what was mentioned before. I hardly know where to begin on this - or whether I want to.
Let me just underline the problem areas of your post above. "Seems not to have been exiled"? I just cited a page with several sources that overrule your "seems".
"All writings"? Hardly. Write instead "all writings that I bothered to read". Once again, see my page cited.
"None set a date prior to AD 70". Once again...oh nevermind.
Did you read that page at all?
