@3 Resurrections, it’s possible that John had written this a little earlier than it was perhaps sent out, I have heard this before. He may have written it 13 years prior, when Paul mentions he knew a man who went to the third heaven. So it being around that time could be possible before he wrote the rest of it and sent it out. That would make sense.
Sorry, MatthewG, but that isn't possible that it could have been written some thirteen years earlier. The reason for this is the identity of the sixth and seventh "kings" on the Scarlet Beast, which was "ABOUT TO arise" in Revelation 17, and was also ABOUT TO "go into destruction". There was a 6th "king" on this Scarlet Beast which John said
"IS" presently in existence, and a 7th "king" which "had not yet come", but when he did, his term would only last for a "little space".
Those 7 and the 8th "kings" on the Scarlet Beast were not regular monarchs or emperors as we suppose. Scripture defines those "kings of the earth" of Revelation 17:18 as being
the high priests of the land of Israel. These 7 "kings" and the 8th "king" were the 8 members of the high priestly family of Annas, which held a virtual monopoly on the high priesthood role for much of the first century from AD 6 until AD 66.
Five of those high priest "kings" had "fallen" in death before John was writing Revelation. The 6th "king" which John said
"IS" still in existence at that time was Theophilus (to whom Luke had directed the books of Luke and Acts). The 7th "king" which "had not yet come" into his office as high priest was Ananus, who would be appointed high priest in AD 63. His tenure as the 7th "king" only lasted a "little space" since he was deposed from that office after only a brief three months, because he had overstepped the bounds of his authority in having James the Just executed.
This imminent coming for Ananus as the next high priest "king" in AD 63 means that Revelation had to have been written AFTER the death of the other five high priests (Annas, Eleazar, Caiphas, Jonathan, & Matthias), but BEFORE AD 63 when Ananus would come into the high priest office as one of the "kings of the earth".
As for the one Paul knew (more than 14 years prior to around AD 57 when 2 Cor. was written) who was caught away to the third heaven and heard words unlawful to utter, I do think this was the writer of Revelation whom Paul had known earlier in the 40's. However, what the man heard in Paradise wasn't necessarily the content of Revelation's prophecies. You see, I see scripture presenting John the author of Revelation as being Lazarus, the disciple whom Christ loved. Lazarus (John Eleazar) the beloved disciple was dead for four days, and his spirit caught away to Paradise when he would have likely heard those words not lawful to be uttered.
