An early date for Revelation Fits:
Pre-AD70, not 90s. Here is why...
An interesting phenomenon happens to the majority report. As the popularity of a certain view grows the number of authorities to that view likewise grows. Thus there is a seeming weight to the view itself but which is really due, not to argument, but to mere weight numbers, later writers merely following after those few earlier ones. It is not surprising that, as the eschatology itself changed, the view of the date of Revelation (and John) would likewise accommodate.Pre-AD70, not 90s. Here is why...
This eschatological downgrade should not seem surprising. This "ology" disintegrated along with ecclesiology (church power structure already forming - Ignatius's "Do nothing without your bishop!"), views on virginity, relics, etc.
Originally the later date view had only Irenaeus and Eusebius as advocates. But later others added their voice - but only on the basis of these two.
However, over against this view is the internal evidence itself, which I already presented earlier. Also some of the sources often brought forth by adocates for a later date are rather suspect. Or the ancient writer is made to say something he didn't, in fact, teach. For instance, one writer implied that Clement of Alexandria was a late-dater. He wasn't. He also wrote this in his "Stromata":
"For the teaching of our Lord at His advent, beginning with Augustus and Tiberius, was completed in the middle of the times of Tiberius. And that of the apostles, embracing the ministry of Paul, end with Nero."
Now notice what is written here. If John was seen as an apostle - and surely he was - and if his teaching ministry was in the 90s, as the futurist position requires, then we have a glaring omission here.
Here is the Muratorian Fragment:
"the blessed Apostle Paul, following the rule of his predecessor John, writes to no more than seven churches by name."
Who are those "seven churches" that John wrote to? Why, none other than the ones mentioned in Revelation 2 and 3!
Tertullian
“Since, moreover, you are close upon Italy, you have Rome, from which there comes even into our own hands the very authority (of apostles themselves). How happy is its church, on which the apostles poured forth all their doctrine along with their blood! where Peter endures a passion like his Lord’s; where Paul wins his crown in a death like John’s! where the Apostle John was first plunged, unhurt, into boiling oil, and thence remitted to his island-exile.”
One does not have a death like someone else by dying after that person!
Note the comparison:
Peter's death followed Christ's.
Paul's death followed John's.
Did Peter die in the 90s of the 1st-century? No. Neither did John. Both died decades before.
Others can be adduced, but hopefully this is enough for one to see that there is a good case for this earlier date, not only on the basis of internal indications, but external, historical witness.
