“Since every faction claimed Scripture for itself and interpreted it according to its own understanding, the result was that Scripture began to lose its worth, and eventually even acquired the reputation of being a heretics’ book and the source of all heresy, since all heretics seek the aid of Scripture. Thus the devil was able to wrest from the Christians their weapons, armor, and fortress (i.e. Scripture), so that it not only became feeble and ineffective against him, but even had to fight against the Christians themselves. He got Christians to become suspicious of it, as if it were plain poison against which they had to defend themselves. Tell me, wasn’t that a clever scheme of the devil?
Once Scripture had become like a broken net and no one would be restrained by it, but everyone made a hole in it wherever it pleased him to poke his snout, and followed his own opinions, interpreting and twisting Scripture any way he pleased, the Christians knew no other way to cope with these problems than to call many councils. In these they issued many outward laws and ordinances alongside Scripture, in order to keep the people together in the face of these divisions. As a result of this undertaking (though they meant well), arose the sayings that the Scriptures were not sufficient, that we also needed the laws and the interpretations of the councils and the fathers, and that the Holy Spirit did not reveal everything to the apostles but reserved certain things for the fathers. Out of this finally developed the papacy, in which there is no authority but man-made laws and interpretations according to the “chamber of the holy father’s heart” (Luther’s Works, vol. 37, p.13-14).
