Mystery of Paul

Mystery of Paul's witness??
Acts 22 is a repeat of chapter 9. In this chapter Paul’s defense from the stars of the fortress, the rage of the audience bursting forth. The Commandant has him brought into the fort to be examined by scourging. But learning that he is a Roman, he orders his release and commands the Samhedrim to try him.
This thrilling dialogue between the glorified Redeemer and his chosen vessel is nowhere else related, no second witness to the Scripture.
All Scripture is back up with at less a second witness, sorry folks I can not find one, can you? I know what we were taught, but not all that we were taught turns out true!
Paul says: Hear the voice of his mouth - in order to place him on a level with the other apostles, who had ‘seen and walked with the risen L-rd’. As you have noticed the other true Apostles did not except Paul as being one for he did not meet the criteria. But he was sent out as a missionary to help plant many churches.
Paul calls their attention to the fact that after his conversion he kept up his connection with the Temple as before.
Being rejected by the Apostles, Paul claims he was sent to the Gentiles: Depart: for I will send thee far hence unto the Gentiles. If you remember Peter was the one sent to the Gentiles. Paul went because the Hebrews did not validate what he said.
Peter being the ‘head’ of the Apostles butted heads with Paul and what changes Paul was trying to make.
I believe Paul was a good missionary; he was well learned in his religion and knew the Words of G-d. In that day all they had was the Torah.
Paul was a good teacher, the Gentiles did not always understand what he was saying, even to this day, for they did not know the times and custom’s of G-d’s people!
Paul did stay mainly with the Gentiles and many were converted out of occult and pagan religion. Who tried cooperating in their holidays in under the name of Christian, and we bought them hook line and sinker.
As to what happen to Paul and his testimony – it could be all true but we seem to have only ‘his’ word on it. Where are the witnesses that were with him to back him up?
If you can find it, and not repeats of what others have heard him say – Please let me know so I can solve this mystery.
