Jewish Christians renounced the material, as did Jesus, believing the kingdom of God was coming down to earth from God, right quick like, as they say in the holler. Paul's Gospel by contrast baptized entrepreneurialism and made free-enterprise and Judaism safe for the world. Hence the tithers of today, and the spread of the congregation on the synagogue model.
Historians would be better engaged figuring out what went wrong there with Paul. Albert Schweitzer figured out what went wrong with Jesus.
