And here we see the 'gist' of the gospel of Jesus as presented in the papers,....its central theme of we being God's children, and the goodnews of realizing his 'kingdom' within that 'relationship'. The gospel of Jesus is clearly repeatedly explained in Part 4 for any interested.
What is most important as taught by the later prophets and confirmed by Jesus is the inward condition of the heart and soul in repentance toward 'God', not the slavish obedience to religious ritual or animal sacrifice which are only tokens, albeit insufficient ones, of the movement of one's own conscience in surrender to Spirit.
All thru-out the later prophets,...the endless sacrifices of blood splattered upon the altars were a stench in God's nostrils,...he abhorred such slaughter (perhaps for its own sake which we've discussed earlier) as well as that it was not accompanied with genuine repentance, so it became valueless, if not powerless to effect a change in their hearts.
Now even while the UB is critical of Paul in some ways, we acknowledge that he did get the revelation of 'sonship' in his own way,...for the Spirit cries out in our hearts "Abba Father",...our spirit bearing witness with His Spirit that we are the sons of God. So some truths Paul did express, but he did not let go of the Jewish and pagan concepts of 'blood atonement' mixing that in with "his gospel", his own customized theology based on his own personal revelations woven with various adopted concepts, allegories, etc. But we still come back to the primay concept of 'sonship with God',...this is the essential focus. "We are His offspring". We are children of a loving Heavenly FATHER. This the UB strongly proclaims, a social gospel founded on the truth of the Fatherhood of God and Brotherhood of Man.
