The bottom line is that Paul did not preach the SAME "gospel" that Jesus, James, Peter, et. al., preached. Paul's Jesus was a version, an import of MITHRAS.
Within the Homilies and Recognitions we see Peter's version of the encounter Paul had with Peter in Antioch and Paul is accused to preaching something that is vastly different than that of the Apostles.
Paul was NOT a chosen Apostle of Jesus. His Apostolic credentials rest solely on himself. See below:
