“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).
“How very true is the proverb that the devil is master of a thousand arts! This he proves beyond question in all the stratagems by which he rules his world, as in outward, palpable deeds of guile, intrigues, wickedness, sins, murder, destruction, etc. But especially and supremely does he demonstrate his craftiness in spiritual, inward matters which concern the glory of God and conscience. How he can slither and squirm, twist and turn in all directions, and hinder and thwart us on all sides, that no one may be saved and persevere in the Christian truth. As an example of the devil’s work let us take the history of Christianity (I shall not mention the ancient fathers and the Jews). In the beginning of the gospel, when God’s Word was preached by the apostles purely and clearly, and no human commandments but simply the holy Scriptures were set forth, it seemed as if there would never be any trouble, since holy Scripture was the empress among the Christians.
In short, the Word and the Holy Spirit, who prepares us for prayer, are in God’s power. It is the Word which we believe—this is what makes our hearts so bold that we dare to call ourselves the children of the Father. Where does this come from? The answer is: From God, who teaches us to pray in the Lord’s Prayer and puts into our hands the book of Psalms. For if we prayed without faith, this would be to curse twice over, as we learned in our nasty papistical holiness. But where there is a believing heart and that heart has before it the promise of God it quite simply and artlessly prays its “Our Father” and is heard. Outside of this church of God you may present your prayers and supplications to great lords and potentates to the best of your ability, but here you have no ability to pray except in Christ Jesus, in order that we may not boast that we are holy as they do in the papacy, who protest, of course, and say: Oh, it would be a presumption for anybody to call himself holy and fit; and yet they teach that man of himself has a “certain preparation” for prayer.
