Irrespective of individual shrines or groups of shrines, reverence of the kami means all kami. Since Shinto is not an anthropomorphic religion with humankind at the center, it can more easily follow the way of kannagara. Religions derived from human initiative or inspiration require some form of interpretation. This is how their transmission and continuity is assured. The more profound and subtle a doctrine is in a philosophical sense, the higher the standing of that religion will be.
Human beings have their limitations, however, and they make imperfect judgments.
Disagreements and conflicts are inevitable. This is particularly true in religions where doctrines are formalized and stated. The more subtle a doctrine is, the greater is the likelihood of disagreement among the individuals or groups involved in interpreting the doctrines. The best example of this in the West is the battle in early Christianity over the definition of the substance of the person of Christ, whether it was like or the same as the substance of God. The difference in Greek was the letter iota.
