John states,
9I, John, your brother and fellow partaker in the tribulation and kingdom and perseverance
which are in Jesus,
was on the island called Patmos because of the word of God and the testimony of Jesus.
John was not taken off the island until the death of the emperor Domitian in 96-97AD.
Therefore the Revelation was written in the (approx.) two years he spent on the island. Somewhere near 94-95AD.
This is Historically accurate, and that some would attempt to dispute the facts is really displaying ignorance on the topic.
Btw, John is the ONLY Apostle that one can actually visit his grave in Ephesus. He was a remarkable man who I will cherish time to get to know far better, soon.
The point being, the date of John on Patmos completely disqualifies him from being the man Paul mentioned.
Patmos was after Paul was long dead.
