The evolution of religion?

There is also the possibility that god/s ARE knowable, but only to certain tribes, who were preselected.There is the chance that god/s ARE knowable, but only to those who have passed the tests, or found the key, or whatever.There is the option that god/s ARE knowable, but what we know changes with time, thus giving the appearance that we are not in any accord with our beliefs.There is the chance that we don't recognize what we know.Why no imagination here?

Would you say that doctrine is part of the initial formation of the newly initiated? Tradition and ceremonial custom are not things designated by leaders, but by the body of the church, the members, and their overall culture. Dogma is not crowd control, it is a belief that is considered non essential or insupportable, and often springs from the crowd themselves.
