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.”
When the devil saw this he jeered and thought: "Now I have won! Scripture lies prostrate, the fortress is destroyed, the weapons are beaten down. In their place they now weave walls of straw and make weapons of hay, i.e., they intend now to array themselves against me with man-made laws. Ah, this is serious! What shall I do? I shall not fight against this, but pitch in and help them build so that they remain nicely united, and help them gather enough straw and hay. It serves my purpose well that they should neglect the Word and not dispute over the Scriptures, but that at this very point they should be at peace and believe what the councils and the fathers say. But within this peace and unity I shall stir up many another controversy and quarrel, so that the pope will contend against emperor and kings, bishops against princes and lords, scholars against scholars, clerics against clerics, and everyone against the other, for the sake of temporal honor, possessions, and pleasure, yet leaving untouched their unity of belief in the holy fathers. The fools! What can they expect to accomplish with quarrels over the Scriptures and the things of God they do not understand? It is better for them to quarrel over honor, kingdoms, principalities, property, pleasure, and bodily needs, which they do understand, and meanwhile remain faithful Christians united in the glossed faith of the fathers, i.e., a flimsy faith."
This is the way the plot worked out for the fathers: Since they contrived to have the Scriptures without quarreling and dissension, they thereby became the cause of men’s turning wholly and completely away from the Scriptures to mere human drivel. Then, of course, dissension and contention over the Scriptures necessarily ceased, which is a divine quarrel wherein God contends with the devil as St. Paul says in Ephesians 6 [:12], “We have to contend not against flesh and blood, but against spiritual wickedness in the air.” But in place of this, there has broken out human dissension over temporal honor and goods on earth, yet there remain a united blindness and ignorance of the Scriptures and a loss of the true Christian faith, i.e., a united obedience to the glosses of the fathers and to the holy see at Rome. Isn’t this also a piece of devilish craftiness? No matter what play we make, he is a master and an expert at the game.
Now in our day, having seen that Scripture was utterly neglected and the devil was making captives and fools of us by the mere straw and hay of man-made laws, we have tried by God’s grace to offer some help in this matter. With immense and bitter effort indeed we have brought the Scriptures to the fore again and released the people from man-made laws, freed ourselves and escaped the devil, although he stubbornly resisted and still continues to do so.
However, even though he has had to let us go, he does not forget his tricks. He has secretly sown his seed among us so that they may take hold of our teachings and words, not to aid and assist us in fostering the Scriptures, but while we were leading in the fight against human drivel to fall upon our host from the rear, incite rebellion and raise an uproar against us, in order that caught between two enemies, we may be more easily destroyed. This is what I call throwing quicksilver into the pond!
However, he does not leave the matter there, but quick as a flash goes to work on the sacraments, although in this respect he has already torn at least ten rips and loopholes in the Scriptures. I have never read of a more shameful heresy, which from the outset has gathered to itself so many heads, so many factions and dissensions, although on the main point, the persecution of Christ, they are united. But he will keep on and attack still other articles of faith, as he already declares with flashing eyes that baptism, original sin, and Christ are nothing. Once more there will arise a brawl over the Scriptures, and such dissension and so many factions that we may well say with St. Paul, “The mystery of lawlessness is already at work” (2 Th 2:7), just as he also saw that many more factions would arise after him.
If the world lasts much longer, men will, as the ancients did, once more turn to human schemes on account of this dissension, and again issue laws and regulations to keep the people in the unity of the faith. Their success will be the same as it was in the past. In short, the devil is too clever and too mighty for us. He resists and hinders us at every point. When we wish to deal with Scripture, he stirs up so much dissension and quarreling over it that we lose our interest in it and become reluctant to trust it. We must forever be scuffling and wrestling with him. If we wish to stand upon the councils and counsels of men, we lose the Scriptures altogether and remain in the devil’s possession body and soul. He is Satan, and Satan is his name, i.e., an adversary. He must obstruct and cause misfortune; he cannot do otherwise. Moreover, he is the prince and god of this world, so that he has sufficient power to do so. Since he is able and determined to do all this, we must not imagine that we shall have peace from him. He takes no vacation and he does not sleep.
Choose, then, whether you prefer to wrestle with the devil or whether you prefer to belong to him. If you consent to be his, you will receive his guarantee to leave you in peace with the Scriptures. If you refuse to be his, defend yourself, go at him! He will not pass you by; he will create such dissension and sectarianism over the Scriptures that you will not know where Scriptures, faith, Christ, and you yourself stand.
Emphasis added to the words in question. This short quotation was originally extracted from the American Edition of Luther’s Works (Philadelphia: Fortress Press, 1961) volume 37, pp. 14-17, Robert H. Fischer, translator/editor (quoted as a "fair use" - should the copyright holder disagree, it is requested that he contact the blog owner through the email found on his profile).
This context provides a rather different sense as to what Luther was trying to say, than the sense conveyed by Cochlaeus and many who have followed him.
But let us not render final judgment. Perhaps Mr. Fischer has rendered the text too kindly to Luther. Perhaps the German or Latin source documents will reveal a pro-Lutheran bias in Mr. Fischer's translation.
Those interested can read more of the document here (link), notes on the work beginning at page 3, work itself beginning at page 13 (bold portion above at page 17), with the last available part of the treatise ending at page 73 (obviously, there is a lot more context that could be provided).
