You have not answered the question. Is it possible for God to call a man today as He did Paul? Paul did not need any approval or blessing from the disciples.
Yes, it is theoretically and mysteriously possible that God could call other Jews in the same way he called Saul.
Paul did not need any approval or blessing from the disciples.
Yes, he did. He had to be in fellowship with the one holy catholic apostolic church to be authentic. Otherwise it would have been like the Reformation or Mormonism. Since St. Paul is an authentic apostle, he was in fellowship with the authentic disciples that the Messiah actually trained, as opposed to those who departed from the faith or imagined they were his sheep.
