Considerable space is given up to an exposure of the errors and abuses of the Papacy, but the exposure is made uniformly by the light of Scripture. Vehement as are Luther's occasional bursts of indignation, he never wanders from the subject, and never ventures beyond where he is sustained by the clear warrant of the word of God. In the purpose of presenting this translation to English readers, I have been encouraged by the prospect of affording to others the same opportunity of acquaintance with Luther's modes of thought and feeling which I have myself enjoyed. I believe, moreover, that his exposition has a high value, apart from the interest which attaches to it as the production of the great hero of the Reformation. Occasionally, the views presented have seemed to be such as required some explanatory note or correction, and in a few instances this has been appended, but the necessity has rarely occurred, and Luther is left throughout to speak for himself. The translation is strictly literal, and almost the only variations from the original are so marked, by being inclosed in parentheses. These will readily be distinguished from the passages or words included in parentheses of the original text, by their explanatory character. It would have been a far easier task to have given a more liberal and polished rendering of Luther's language. But I think most readers would prefer to have me give them Luther, rather than--the translator. There are occasional roughnesses of expression, and some sentences which were evidently not very lucidly reported, but they are features of the book which presents Luther to us, and even the wart on the face must appear in the faithful portrait. For assistance in the labor of revising some of the more difficult passages, I am indebted to Prof. ROBINSON, of the Union Theological Seminary, and to Rev. M. BUSHE, pastor of a German church in this city. By their aid, which I take this occasion gratefully to acknowledge, I feel confident that nearly every passage, in which the text of the original is not in fault, has been correctly rendered. I had hoped, in this connection, to present an estimate of Luther's writings, from the pen of one of the most eminent German scholars which our country can boast. The permission to do so was kindly granted, but the limited space allowed for prefatory remark forbids it. I will only add the expression of my own conviction, that from the exceedingly voluminous works of Luther, other selections of high merit might be made, the translation and publication of which would be welcomed with grateful acknowledgment by a large class of American and English readers. I should be highly gratified if the encouragement afforded by my words or example should induce any one more competent than myself, or who can command more leisure for it, to prosecute the work which I have only just begun.
