ok ok,, i was gonna wait...
Did ya ever read Acts?
Every single thing which happened to Peter happened to Paul.. They both spoke in tongues, they both healed people, they both had 11 Apostles following them......... the Holy Spirit (when He was writing the books of Acts) was very precise in documenting this...
I'm sure, Paul's credibility was unquestioned
by those who followed Him... So, with Paul and his band on an equal playing field, these books were floating around, signs following and all. I'm sure People at that time had no question as to which books were "Authorized". People were rising from the dead!
I tend to agree with the early dating of Revelation, somewhere around the Gospel of Mark>43 AD...
Most everything we have today was written and in circulation prior to God's judgment on Jerusalem in 70ad... The end of Acts was around 63ad. Paul wrote 7 letters after that (63 - 66ad)... Acts itself was written around 64ad..
Imagine living in a time were evangelists were being teleported to other cities!! I mean, how would they not know?
