Thomas B. Slater, «Dating the Apocalypse to John», Vol. 84 (2003) 252-258
The present study re-examines the major arguments for dating the Apocalypse to John. It argues that internal evidence should be preferred over external witnesses and that the internal evidence suggests, based upon the ex eventu prophecy in Rev 17,9-11, that the book was written in 69, either late in Otho’s reign or early in Vitellius’ reign.
predicts that he will return, an appropriation of the Nero redivivus myth. It is a stretch to argue that the Nero redivivus myth preceded Nero’s death. Thus, the Apocalypse does indeed contain ex eventu prophecy. It is quite possible that John wrote during the reign of Galba, but it is also possible that he wrote during the reign of Otho who "must only rule briefly" (17,10). To this point, John’s prophecies are historically accurate. They are inaccurate with the next ruler, Vitellius, who in no way reminded people of Nero. According to the rules of ex eventu prophecies, the book should be dated at the point where the prophecies are not fulfilled. It is possible that John was writing in 69 late in Otho’s reign or early in Vitellius’ reign.
I am, therefore, in general agreement with a date between 68-70 CE and would add one more additional bit of internal evidence. There are two examples, found in Rev 2,9 and 3,9, which have been overlooked. In both passages, "Jew" is an honorific term, the religious ideal. This means that John sees himself first and foremost as a faithful Jew and that he sees the Christian community as the true Israel. His opponents are not criticized because they are Jews but because they are not faithful, righteous Jews. Such a self-identification by a Christian is more understandable in the 60’s than in the 90’s when Christians and Jews were beginning to see themselves more as separate groups. I am aware that the separation of Christianity from Judaism was a gradual, regional event that occurred at different times and different places throughout the Roman Empire; however, it is more likely that one in the Christian movement would see himself as a Jew during Nero’s reign than during Domitian’s.
An earlier date would also help to explain why the book is so Jewish and also why some exegetes have postulated that chapters 1, 2, 21 and 22 constitute a Jewish apocalypse; chapters 3–20, a Christian one22 It is both Christian and Jewish at a point in time when this fact would have been a given for the original readers. Such a self-designation and self-understanding is much more intelligible in the 60’s, when Christianity was still very much within the Jewish religious community, than the 90’s, when Christianity saw itself more and more as separate and distinct from Judaism.
