Though I believe there are many blaring examples of the supposition I put forward here, I will attempt to describe the roots in very general terms.
Jesus Christ probably existed and he appeared to be quite anti-establishment and humanist. The powers that be could not handle the small neighborhood meetings that were going on where Jesus' ideas were shared. In order to curtail this avenue of sharing and people empowering, the power holders claimed themselves the only true followers of Jesus Christ and dictated a set of "rules" or "conventions" that channeled that force into supporting and fomenting allegiance and servitude to the establishment. The moralistic implications of Jesus' life as example were drowned out by interpretation and spin to serve the powers that be, the top dogs of anarchy.
There has been only one Christian. Anyone who now lays claim to that name in reference to that person does so without his express consent. Christianity is a refuge of scoundrels. It is all pretense.
Many similar irrational ascriptions exist. They are driven by a protracted alienation and existentialism, anomie. There is a point where a person's world model is so far from accurate that belief manufactures apparent evidence and denys anything contrary. Sounds incredible but it is true and has been spoken of by many philosophers under the phrase "epistemological relativism." It is basically the opposite of the scientific method, rather than look to the world to select the best of what is possible, an attempt is made to force an opinion of how the world should be. It is only to be expected that this mental aberration, this psychological affliction, would be characterized by reference to the various institutionalized bastions of callousness, the so-called religions. They and many other institutions serve as the shields behind which the heartless and cruel wage their wars of domination and forced servitude.
I think there were some understandings that Jesus came to that were a bit worthy. That doesn't mean I'm a Christian, more like, Jesus was a bit Chipian. [lol]
