As mortal human beings, we cannot understand absolute truth as God understands it. Therefore, any creed constructed by the Church would be both incomplete and imperfect. Neither their authors, the councils which adopted them, nor those who presently accept them, make any claim that revelation or inspiration was present in their formulation and promulgation, although attempts are made to show that the various articles in them conform to the teachings of the scriptures. In that we believe the Bible, and all other sects profess to believe their interpretations of the Bible, and their creeds. Church leaders have taught that there is a strong correlation between belief and action.
Creeds do count.
Concepts do have consequences. This type of thinking led to the various crusades, the sacking of Constantinople in 1204, the Catholic-Protestant wars of the late Middle Age, and similar episodes. The preaching and publishing of its doctrines has had a marked effect in molding and modifying Christian views and sentiments, and in changing the creeds of the churches. Random House, 1991.
