Does a Catholic opinion exist with regard to Luther’s personal qualities and his fate? Does the much-discussed work of Denifle represent the “Catholic feeling”? That it does has frequently been asserted by those most strongly opposed to Denifle. Yet Denifle’s manner of regarding Luther was, on the whole, by no means simply “Catholic,” but largely biassed by his individual opinion, as indeed has ever been the appreciation by Catholic authors of the different points of Luther’s character. Only on those points could Denifle’s opinion strictly be styled “Catholic” where he makes the direct acknowledgment of dogmas and the essential organisation of the Church the standard for Luther’s views and reforms; and in this he certainly had on his side the repudiation of Luther by all Catholics. A “Catholic opinion,” in any other sense than the above, is the sheerest nonsense, and the learned Dominican would certainly have been the last to make such a claim on his own behalf. The present writer protests beforehand against any such interpretation being placed on his work. The following statements, whether they differ from or agree with those of Denifle, must be looked on as a mere attempt to express what appears to the author to be clearly contained in the sources whence his information comes. In all purely historical questions, in questions of fact and their inferences, the Catholic investigator is entirely free, and decides purely and simply to the best of his knowledge and conscience. A list of Luther’s writings with the volumes in which they occur in the last two editions, as well as a detailed index of subjects and names at the end of the sixth volume, will facilitate the use of this work. The author would like to take this opportunity of expressing his most cordial thanks to the Royal Bavarian Library of Munich, and also to the University Library in that city, for the friendly assistance rendered him. These rich sources of information have afforded him, during his frequent and lengthy visits to the Bavarian capital, what the libraries of Rome, which he had been in the habit of consulting for his History of Rome and the Popes of the Middle Ages (Eng. trans., 3 vols., 1911-12), could not supply on the subject here treated. The author will now return to the exploitation of the treasures of Rome and to the task he originally undertook and hopes to bring out, in the near future, a further volume of the History of Rome.
