This view implies that what people say, in the Apostles' Creed, for instance, is not revealed. Such verbal expressions are fallible human attempts to talk about revelation. On this view, the Church necessarily speaks falsely in asserting that there are certain irreformable truths, which certainly give us true information about God, reality ourselves. This view of revelation is heretical. It was condemned, among other false views, as Modernism at the turn of the last century.
Many people today are egalitarians when it comes to revelation.
Quakers used to be distinguished by their view that all one needed to know about God was located in the heart of each person. Now, most people seem to be Quakers. They rely upon discovery of their innermost feelings and thoughts for salvation, thus showing that they, like Quakers, think it is all there deep down with us. God could have operated that way. But, as DV pointedly describes it, He chose otherwise.
