I suspect that many people who would call themselves “Reformed” in their theology, have never actually read much that Luther wrote. If you want to get started, The Bondage of the Will, would be a good place to begin.
At least read the brief excerpt below. Keep in mind that Erasmus was one of the most respected theologians of the day. Indeed, Luther addresses him as the “venerable.” But, things quickly heat up from there.
Luther’s basic point here is that Erasmus’ previous work was so weak that Luther “greatly felt for him,” or as another translations says, “your book struck me as so cheap and paltry that I felt profoundly sorry for you.”
Martin Luther, to the venerable D. Erasmus of Rotterdam, wishing Grace and Peace in Christ.
THAT I have been so long answering your DIATRIBE on FREE-WILL, venerable Erasmus, has happened contrary to the expectation of all, and contrary to my own custom also. For hitherto, I have not only appeared to embrace willingly opportunities of this kind for writing, but even to seek them of my own accord. Some one may, perhaps, wonder at this new and unusual thing, this forbearance or fear, in Luther, who could not be roused up by so many boasting taunts, and letters of adversaries, congratulating Erasmus on his victory and singing to him the song of Triumph – What that Maccabee, that obstinate assertor, then, has at last found an Antagonist a match for him, against whom he dares not open his mouth!
But so far from accusing them, I myself openly concede that to you, which I never did to any one before:- that you not only by far surpass me in the powers of eloquence, and in genius, (which we all concede to you as your desert, and the more so, as I am but a barbarian and do all things barbarously,) but that you have damped my spirit and impetus, and rendered me languid before the battle; and that by two means. First, by art: because, that is, you conduct this discussion with a most specious and uniform modesty; by which you have met and prevented me from being incensed against you. And next, because, on so great a subject, you say nothing but what has been said before: therefore, you say less about, and attribute more unto "Free-will," than the Sophists have hitherto said and attributed: (of which I shall speak more fully hereafter.) So that it seems even superfluous to reply to these your arguments, which have been indeed often refuted by me; but trodden down, and trampled under foot, by the incontrovertible Book of Philip Melanchthon "Concerning Theological Questions:" a book, in my judgment, worthy not only of being immortalized, but of being included in the ecclesiastical canon: in comparison of which, your Book is, in my estimation, so mean and vile, that I greatly feel for you for having defiled your most beautiful and ingenious language with such vile trash; and I feel an indignation against the matter also, that such unworthy stuff should be borne about in ornaments of eloquence so rare; which is as if rubbish, or dung, should he carried in vessels of gold and silver. And this you yourself seem to have felt, who were so unwilling to undertake this work of writing; because your conscience told you, that you would of necessity have to try the point with all the powers of eloquence; and that, after all, you would not be able so to blind me by your colouring, but that I should, having torn off the deceptions of language, discover the real dregs beneath. For, although I am rude in speech, yet, by the grace of God, I am not rude in understanding. And, with Paul, I dare arrogate to myself understanding and with confidence derogate it from you; although I willingly, and deservedly, arrogate eloquence and genius to you, and derogate it from myself.
Wherefore, I thought thus – If there be any who have not drank more deeply into, and more firmly held my doctrines, which are supported by such weighty Scriptures, than to be moved by these light and trivial arguments of Erasmus, though so highly ornamented, they are not worthy of being healed by my answer. Because, for such men, nothing could be spoken or written of enough, even though it should be in many thousands of volumes a thousands times repeated: for it is as if one should plough the seashore, and sow seed in the sand, or attempt to fill a cask, full of holes, with water. For, as to those who have drank into the teaching of the Spirit in my books, to them, enough and an abundance has been administered, and they at once contemn your writings. But, as to those who read without the Spirit, it is no wonder if they be driven to and fro, like a reed, with every wind. To such, God would not have said enough, even if all his creatures should be converted into tongues. Therefore it would, perhaps, have been wisdom, to have left these offended at your book, along with those who glory in you and decree to you the triumph.
Hence, it was not from a multitude of engagements, nor from the difficulty of the undertaking, nor from the greatness of your eloquence, nor from a fear of yourself; but from mere irksomeness, indignation, and contempt, or (so to speak) from my judgment of your Diatribe, that my impetus to answer you was damped. Not to observe, in the mean time, that, being ever like yourself, you take the most diligent care to be on every occasion slippery and pliant of speech; and while you wish to appear to assert nothing, and yet, at the same time, to assert something, more cautious than Ulysses, you seem to be steering your course between Scylla and Charybdis. To meet men of such a sort, what, I would ask, can be brought forward or composed, unless any one knew how to catch Proteus himself? But what I may be able to do in this matter, and what profit your art will be to you, I will, Christ cooperating with me, hereafter shew.
