ON THE HISTORICITY OF ST PAUL

Maybe Paul lived before Jesus was invented ? However did even Paul have a historical reality? Were Paul's writings really by Simon Magus or Marcion ?

Oliveira reviewing " The Amazing Colossal Apostle " by Robert.M. Price says

Further down the controversial river, Price sides with Detering in the supposition that the Magus (a historical figure known to Josephus) was the real personage while Paul of Tarsus became a fictive literary device onto which certain theological expectations could more easily be pinned.
Price's case for conflating both Simon Magus in the Christian literature and in Josephus is quite compelling, and while his argumentation regarding the conflation with Paul is sketchy, it is not entirely irrational and illogical. Drawing heavily on Josephus' accounts of Simon and his dealings in Queen Helena's court, Price reconstructs a relatively well documented view of the historical Simon. He then proceeds to extrapolate from numerous other less obvious (and less trustworthy) accounts that hint at the magician. His final historical reconstruction is of a splintering sect rudderless after the sudden death of its spiritual leader (i.e., the Essene Teacher of Righteousness or John the Baptist) evolving into diverging factions under different leaderships (e.g., Ebionites, Sabeans, Mandeans, Nasoreans, Gnostics,
etc.). Some of the leaders emerging from this traumatizing event might have included Simon the Samaritan (a.k.a. the Magician), Jesus the Nasorean (a.k.a. the Anointed), and later, Marcion of Pontus.

REWRIT LUKE 11v 37-53. One day Jesus was teaching near Jerusalem. A crowd formed around him eager to hear him. Jesus said to them, " Beware of the Pharisees for their ideas about Hades & Tartarus come from the nonsense of Greek mythology, and beware of the scribes for they write into the mouths of our ancestors what they wish their ancestors had said, and beware of the teachers of the law because their rules are mostly worthless taboos which they don't even keep themselves, and watch out for those who claim a supernatural realm and yet fail to tell you of what can be known of the physical world and the technological solutions to disease and hunger, and watch out for the historians for due to the lack of written history they feel free to write their propaganda as if it was real history. 
Rather seek first to develop a scientific method based on accurate observation of events in the natural world, carefully written & recorded & stored for future analysis. Blessed are the eyes that can see this, for many are they who have been deceived by religious leaders and politicians, mistakenly trusting that they had studied properly and gave an honest evaluation "
