@Wordsmith courteously requested recently that I submit internal evidence from Revelation itself which proves the date of its composition. Many scholars have spent copious amounts of time and full-length books on this very subject of Revelation's composition date, which I believe was written sometime around early AD 60, as I am going to attempt to prove in a comparatively brief series of comments.
As I have written before, my first introduction to the view of Preterism 12 years ago was in a careful study of Dr. Gentry's dissertation, "Before Jerusalem Fell", which covers the external evidence that is used for a late date, and proves where it is defective or lacking. On the other hand, some of Dr. Gentry's proofs for an early date are flawed, and he is also missing several proofs of internal evidence for an early date as well. He proposes a mid-to-late 60's date, which is a few years too late by Revelation's own internal witness.
For the Preterist views to hold water, this evidence of the dating of Revelation is an absolute must, since so many of the prophecies hang on the time-relevant language which John used extensively throughout the book. This language itself is the determining factor for anyone trying to interpret Revelation's visions. When John announced that all his visions of the future were "at hand" in his Revelation 1:3 introduction and his Revelation 22:10 conclusion to the book, if we don't know what year the book was written, then we can't understand which generation these "at hand" visions applied to.
There are enough pieces of internal evidence in Revelation itself to cross-reference and triangulate with each other, which all unite to present a very precise time frame for the composition of the book around early AD 60.
Revelation written just after early AD 60
We can begin with John's own statement in Revelation 1:9 of his then-current situation of a tribulation period which he was experiencing at the time. "I John, who also am your brother,
and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ."
Christ had predicted for His disciples that they would endure tribulation and be persecuted from city to city in their evangelistic efforts during those early years of the church. So, which particular period of "tribulation" was John then experiencing? It has to be the one which coincides with all the other early-date internal evidence in Revelation - the one which occurred in the aftermath of the Ephesian riot of the silversmiths in AD 57; Ephesus being the capital of all Asia at the time, with the island of Patmos some 60 miles southwest of Ephesus, and under its jurisdiction.
Paul spoke about this period of persecution in Asia in 2 Corinthians 1:8 (written around AD 57). "For we would not, brethren, have you ignorant of
our trouble which came to us in Asia, that we were pressed out of measure, above strength, insomuch that
we despaired even of life:" Paul said that in this case God had "
delivered us from so great a death..." on this occasion, was even then continuing to deliver them, and would yet deliver them.
The riot in Ephesus instigated by Demetrius and the silversmiths against Paul's teachings was described in rather understated terms in Acts 19:23. "And the same time there arose
no small stir about that way..." We've all read about the screaming 2-hour pep rally for the goddess Diana in the Ephesus theater which seated some 24,000, with Paul's two traveling companions dragged into the theater in front of the screaming throng. Paul desperately attempted to join his companions, but was prevented by other disciples - quite possibly Aquila and Priscilla, whom Paul later praised for "laying down their necks" on behalf of his life (Romans 16:3-4). The murder of the faithful Antipas on the Pergamos altar in Revelation 2:13 probably took place during this same time in Asia, as a fallout effect of this Ephesian riot.
Once the riot was finally calmed down by the town clerk, the Jews present in that capital city of Asia still remained actively opposed to the widespread success which Paul's teaching had caused in all of Asia (Acts 19:10, 26). Taking advantage of the Greeks' hatred for Paul's teaching, the similar hatred that the Ephesian Jews hostile to the faith bore for Paul continued to stir persecution afterward for the saints in Asia; so much so, that during Paul's AD 60 visit to Jerusalem, those Ephesian Jews seeing him there in the temple stirred up the people against Paul and attempted to kill him then and there on the temple stairs (Acts 21:27-31).
Paul had been continually warning the Ephesian elders for three years that after he left them in AD 60, "grievous wolves" entering the church would begin to draw the disciples away from the faith by perverse teachings (Acts 20:29-31). The faithfulness of the Ephesian church would begin to drift from the time of Paul's departure in AD 60 onward. This same defection was recorded by John as an accusation against the Ephesian church of having "left your first love" in Revelation 2:4.
In general, the Ephesian church had a commended record of their past labor, patience, a refusal to tolerate evil, having borne times of testing with patience, and not fainting under it (Revelation 2:2-3). This applied to their faithfulness in the period of persecution for the Ephesian church between the Ephesus riot in AD 57 and when Paul finally left them in AD 60. That was the point when their faith quickly began to drift. John noticed this and rebuked them for leaving their "first love" in Revelation 2:4. This means that John was writing Revelation in AD 60 when that defection was first starting to evidence itself in Ephesus. This defection would grow progressively worse in Asia towards the end of Paul's life before his AD 67 martyrdom.
John himself said he was a fellow "companion" experiencing this "tribulation" period in Asia, which was the fallout effect of the Ephesian riot in AD 57. The persecution and "perverse" teaching which the Ephesus church would experience would shortly result in Paul's discouraging estimate of the state of all the Asian churches in 2 Timothy 1:15 (written around AD 67 just before Paul's martyrdom). "This thou knowest, that
all they which are in Asia be turned away from me..." Only Onesiphoris was then being commended for his ministry to Paul in Ephesus (2 Timothy 1:16-18). The majority of the churches in Asia by then had distanced themselves from Paul under the withering persecution by the hostile Jews and also the Greeks who worshipped Diana.
