One answer to this question might be explored by investigating the history of the emergence of the Christian state religion at Rome in the later 4th century. Pitched battles were held in the streets of Rome between the militant forces of a number of claimants for the (tax-exempt) position of the Bishop of Rome.Solstice wrote:Which leads me to: "who were the Petrines?"
After fierce fighting that left many dead in the streets, the winner was Damasus who was also (sometime later) the first Christian bishop to assume the role of Pontifex Maximus. Damasus renovated the Roman catacombs and started the Christian tourism business in Rome, a lucrative business that still operates today. One of his main slogans was "PETER WAS HERE" which might make him a candidate for people to be termed "Petrines".
Platonism, Stoicism, Pythagoraeanism are capable of being seen as non-Christian Gnosticism.Solstice wrote:My question before I keep plowing forward: Would there have been any forms of Christian Gnosticism which were totally of pagan/Gentile origin, with no reliance whatsoever upon Hebrew/Israelite/Pre-"Judaism" scripture?
Unfortunately the Christians saw these philosophical schools as "heretical sects".
