Dating the Apocalypse
“It is most remarkable that not only in Revelation do we find large patterns of evidences befitting the AD 60s era, but also even many smaller details. It it surely no accidental similarity that allows us to find not only particular personages (Nero), cultural structures (the Jewish Temple), and historical events (the Neronic persecution and the Jewish War) that harmonise well with the Neronic era, but even time-frames for these that fill out the picture of the era of which John wrote. It can be no other than in the mid- to late AD 60s.”
Kenneth Gentry, Before Jerusalem Fell, p. 255-256
