It really is important to understand how the Bible was foisted on the Roman subjects and how the ideas of God and his son came direct from pagan belief, and this I suggest is the basis for the strange and permanent ambiguity of Jesus (or the Christ figure) with his father or the conflation of Jesus with God.
Both the father and his son were the Sun gods in antiquity, that was according to the universal rustic myths on which the Bible drew strength and popularity. After sanctifying a specific selection of manuscripts by imperial order, (making the Bible) the new Catholic church proscribed all former texts. This event explains the absence of manuscripts which would have exposed their devious methods. In the main we do not have the source material available because it was deliberately destroyed and made a subject of heavy penalty to be found possessing them. The tangible link between pagan tales and the Bible was severed and censured by the Catholic Church in the interests of empire and raising the sacred status of their new Bible canon.
There is no ultimate arbiter for any religious doctrine. The reason being that they are not about reality, only partisan interpretations of text. That is why the discussion of conflicting Biblical meanings grind on through the centuries getting absolutely nowhere. No growth, no development! It truly is a distraction from the more important and solvable problems of being human.
God and Jesus are primitive fictions for people snagged in a childhood mentality of subservient obedience.
Personally, apart from deconstructing the reasons for their inclusion, I am completely tired of the utter folly of trying to find meaningful information from unprovable words of unprovable spirits. The Bible is not the answer to human problems, it creates them.
