Yeh I believe Paul was talking about the author of Revelation. On Pentecost there are people from all nations under heaven in one spot, 3000 believes in Jesus then they would of travelled back to their home countries (Asia was one which is where the 7 churches were) started churches, and so by 41 AD the churches could of been running for 8 years (assume the crucifixion was 33 AD, and they went back home after Pentecost, and started churches right away), and started to develop doctrinal problems. We find one of the Herods had enough political power in Judea to kill John the Baptist around 33 AD so Antipas that was killed in Revelation could of been killed by one of the local Roman politicians in Pergamon. Roman politicians could kill anyone they want in that city (will look for source). So there is no date problem for the churches in Revelation being 41 AD. 41-54 AD was Claudius Caesars rule, and he kicked Judeans out of Rome (Acts 18:2) 49 AD whether Christian or non Christian Judeans. He observed Christianity started in Judea, and saw there was conflict between Judeans about Jesus, and just wanted them gone
In
Claudius 25 Suetonius refers to the expulsion of Jews by Claudius and states (in
Catharine Edwards' translation):
[1] Chrestus= Christ/Jesus.
Slavonic Josephus says Claudius exiled Christians to distant lands, and that was 44-48 AD
Gnostic John the Baptizer - III. The Slavonic Josephus' A... | Sacred Texts Archive so Claudius was known to just kick people out of places, and not kill them which is Johns (whoever John was) situation in Revelation.
There is no internal or external problem with Revelation being written 41 AD. The earlier the better as ch 1-12 was about to come on the whole land of Judea- Gods worst judgement in history on OT Israel, and the end of it never to return again.
As for other external dates they range from Domitian, Claudius, Nero, even Caligula. I believe inspired scripture stopped 70 AD so i go with internal evidence over external evidence.
Someone 900-1000 AD said Antipas was burned alive in a metal bull but this is very late, and no early sources say it. Chapt GPT said there was one early source about Antipas but I could not find it. Will look again.
