Most of the writings that are known as the New Testament were established by canon around 200 CE. In this process the “fathers” of Christianity were highly selective in the choices of their scriptural literature, often rejecting some parts within a literary work or even rejecting complete works of the same general tone. This gathering took place to set up the politics to be structured into their faith system and it required careful pruning and rejection of many literary works that were in use by outlying Christian cults that were springing up throughout the Roman Empire. The “fathers,” in their zeal to impose a management system upon as many seekers as possible, indulged themselves in a pick-and-choose orgy of various works that often proved to be too contradictory.
With politics of the struggling faith system always in the back of their minds the “fathers” therefore found the Gospel of John to be tolerable but cast aside similar works such as the Dialogue of Thomas. The Gospel of John happened to be written in such a manner that it could be utilized (read altered) to promote certain policies that the “fathers” favored. Gnostic-like works such as the Dialogue of Thomas and similar works encompassed a much broader and freer acceptance of religious practice than the power-seeking “fathers” liked. The “fathers” wanted the people to become totally reliant upon the dictates of church representatives. If seekers believed that one could approach the power that was personified as “God” only through his son-agent, and the church was the son’s representative, then the church had to be obeyed.
Thus the Gospels that were not rejected survived simply because they served the political needs of the newly emerging authority-seeking priest class. The shapers of the Christian cult in 200 CE followed the example of priest-authors devoted to Yahweh in the 7th century BCE in Jerusalem who understood that the basic institutional structure of their religion had to have the apparent support of “authorized” scriptures.
The political platform upon which episcopal authority (church government) campaigned and overran the more natural and honest religions at that time was the insistence that each person had to have a means beyond their own personal power to approach the creative primacy that was/is personified as “God.” In this way the concept of “salvation” became totally a churchly matter and no longer a personal affair between each person and the Creator. This irrational intrusion of the church being thrust between a seeker and the Absolute had to carry the appearance of being divinely ordained if it was to become an influencing factor over the masses. And this is what accounts for the selection of Gospels that have been held out for nearly 2000 years as God’s approved pathway to heaven. It was simply coincidence that those painstakingly selected works allowed for the souls of seeker to be held hostage as a means of financial resources and political muscle for the church.
