or maybe the only explanation for all the issues surrounding the Apocalypse:

Who wrote it?

When was it written?

Why was it written?

John the Baptist wrote the first Apocalypse before he knew Jesus was the Lamb of God.

He was preparing the way for the first coming not the second.

John the Apostle  later updated it with Jesus, Antipas, and the seven churches.

He was addressing the Baptist followers in Ephesus.

John Chrysostom witnessed the sixth of seven fallen dynasties

He was in Ephesus shortly before Jerome included the Apocalypse in the Vulgate.
