Of the sermon or tract upon the _Sale of Indulgences_, Kapp records ten authorised editions in the two years succeeding 1518, and three editions issued respectively in Leipzig, Nuremberg, and Augsburg, which are specifically described as unauthorised. The next of the series of tracts of this year, _Decem Precepta Wittenbergensi Predicata Popula_, was printed in the Latin form in five editions, and in the German version in seven. Among the latter are included three unauthorised issues, again dating from Leipzig, Augsburg, and Basel. There was also a Bohemian edition issued in Prague in 1520. It is not surprising that printers like Petri, working at so distant a point as Basel, should have felt free, with “missionary” material of this kind for which there was an immediate popular demand, to put forth editions without reference to the author. It is somewhat surprising, however, that unauthorised editions should also have been issued in Leipzig, but a few miles from Wittenberg, as with the leading publishers of Leipzig Luther and his Wittenberg associates had maintained satisfactory relations. Other tracts of this period, the most of which were printed in the same publishing centres, and the editions of which, both Latin and German, were promptly absorbed by the public, were the _Resolutiones Disputationum de Indulgentiarum Virtute_, the German version of the hundred and tenth _Psalm_, and the _Sermo de Virtute Excommunicationis_. The complete Lutheran version of _The New Testament_, published in 1522, constituted not only, as the historians of the time make clear, a central fact of first importance in the work of the Reformation, but the most noteworthy of the literary productions of its author. The work is of necessity classed as a translation, but it was a translation into which had been absorbed, in very large measure, the individuality and original thought of the writer. The production of this German Bible was an essential part of the work of the Protestant Reformers. The teaching that Christian believers must base their relations with their Creator upon the inspired Word required that this Word should be placed within reach of all Christians and should be in a form to be understood by the unlettered as well as by the scholarly.
