639. That no faith imputative of Christ's merit is taught in the Word, is very clear from the fact that this faith was unknown in the church until after the Nicene Council had introduced the doctrine of three Divine persons from eternity. And when this faith had been introduced and had pervaded the whole Christian world, every other faith was cast into the dark, so that whoever since that time reads the Word, and there sees anything about faith and imputation and the merit of Christ, naturally falls into that which he has believed to be the one only thing; like one who sees what is written on one page and there stops, not turning the leaf and seeing what is on the other page; or like one who persuades himself that a certain thing is true (although it is false), and confirms that only, and thereafter sees falsity as truth and truth as falsity, and sets his teeth and hisses at everyone opposing it, saying, "You have no intelligence." Thus the man's whole mind is in it, covered over with a callousness which rejects as heterodox everything that does not agree with his so-called orthodoxy; for his memory is like a tablet upon which is written this single ruling tenet in theology; and when anything else enters there is no place where it may be inserted, and he therefore casts it out as the mouth casts out froth. For example, if you say to a confirmed naturalist who believes that nature created herself, or that God came forth after nature, or that nature and God are one, that the very reverse is the truth, would he not look upon you as one deluded by the fables of the priest, or as a simpleton, or a dullard, or as demented? So it is with all things that are fixed in the mind by persuasion and confirmation; which finally appear like pictured tapestry fastened with many nails to a wall built of old stones.
