Most people struggle between soul and brain. The God system provides for as many incarnations into unclean flesh (swine) as needed for soul to dominate. Therefore, we are all at different levels of soul development when we enter this world. Some will assimilate soul/spiritual nature better than others (get the pay after working a short time). But for us all, we share the purpose of spreading godly values (working in the vinyard). This is how we "pay the debt to the last cent" that will get us out of the prison that human incarnations are to the soul. This is the Law (karma), not the Hebrew laws. A Christian assumes the responsibility of being God's agent in this sphere. Jesus does not teach vicarious atonement. Jesus's parables do not teach that the God/source intervenes in the physical realm. Jesus does not teach that your sins will be forgiven; he taught that you have to work off that debt. Faith will get you nowhere except as a springboard towards understanding.
There never was one Christianity. There were two levels, one for the "children" (beginners who had undergone an immersion ceremony) and the other, with far fewer numbers, for the initiated or those committed to initiation. (Their ceremony is referenced by Lazarus and the naked youth at gethsemane.) Eventually, the initiated were called heretics, but it is their God system which underlies the parables.
