One comment: That is incorrect. The authorship and dating of Revelation to the time of Domitian's reign was written on by Irenaeus in the second century....1400 years before Erasmus compiled the Greek NT and 1500 years before the KJV was first compiled. In book 5 of his "Against Heresies, [5: 30: 3] he says that the book was composed "towards the end of Domitian's reign."
A lot of when you think Revelation was written depends upon whether you believe in a literal future fulfillment, or you are a preterist. Now...I am not saying that Revelation was written in 90 AD...to me it really doesn't matter who sent John to Patmos or when it happened...I am still a futurist...and beleive in a future filfillment of Revelation. However, my point in this post is to correct the misconception that the KJV scholars back dated it. It had been back dated to the late date back in the 2nd century. Of course, Clement in the 2nd century dated the book to Nero's reign...but you get my point.
Scholars such as Adams cite the Temple still standing in Rev 11 as "proof". That is fine if you are a historist or a preterist. However, many believe the temple will be rebuilt and I believe that as well. Jesus discussed the Anti-Christ sitting in the temple (abomonation of desolations) which proved that the passage in Daniel was NOT fulfilled when Antiochus Epiphanes desolated the temple. So....all arguements that come from the angle "this referred to that...and can't be because the temple is there...or this referred to the Jewish war" have to be thrown out simply because the point of view of the scholar clouds the judgment...i.e...the scholar looks at the book from a particular angle. There is no proof that the temple in Revelation 11 refers to the same temple that was destroyed before 70 AD. There is no proof that it does not. There is no proof the persecutions point to the Jewish war. There is no proof it does not.
So...the date depends on your escatological point of view. If you are a preterest...then Rev 11 is proof poitive of a pre 70 AD date because the temple is there. If you are a futurist...it really doesn't matter when the book was written because Rev 11 is future still (and I believe it is...simply because the Temple in Rev 11 was not the temple of pre-70...and in Rev 11...the diminsions of the temple are being re-measured). But again...it is all opinion.
And BTW....Revelation was canonized in 393 A.D. at the Council of Hippo and in 397 A.D. at the Council of Carthage. This canon was set in stone long before the KJV scholars...there was no need to late date it to make it more canon...it already was.
