This may sound like an academic concern, but it is actually quite relevant. Leithart, The Promise of His Appearing (2004 PDF) • J. Marshall, Parables of War: Reading John’s Jewish Apocalypse (Studies in Christianity and Judaism, 10; Waterloo, Ont.: 2001) ; `Who’s on the Throne?
This is because if Revelation was not written before 70AD, then it was likely not warning its audience about the Destruction of Jerusalem in 70AD.
In each case, however, the shift is arbitrarily assigned based upon what the interpreter feels has not been fulfilled yet. al., Studies in the Apostolic Church (New York: 1902), pp.
HOWEVER, there is no indication from the text that a shift in audience or time of fulfillment is EVER to be made.
But perhaps, just perhaps, Revelation’s fulfillment gave us what we desperately needed – and not what our material appetite wanted.
Maybe it is our traditional doctrine of doubt that has made this letter more complex and enigmatic than it needs to be. The early church was fighting the Trinitarian wars. Gingrich, A Greek—English Lexicon of the New Testament and Other Early Christian Literature (1979).
And that this is why they match in content and timing.
Berkof says that no one in church history has undertaken a thorough study of eschatology. The Reformers were fighting the salvation wars, thus, Calvin and Luther wrote a commentary on every book of the Bible but Revelation.
Luther didn’t even think Revelation should be in the Bible!
At the end of the letter, none other than Jesus Himself confirms that He is coming SOON – to THEM!
This timing perfectly aligns with Jesus’ parallel teachings in his landmark Olivet Discourse by Matthew, Mark and Luke about how Jerusalem would be destroyed before the end of his generation.
