After the invention of the printing-press, and before the Reformation, this mediaeval German Bible was more frequently printed than any other except … - Philip Schaff

The Pre-Lutheran German Bible. The precise origin of the mediaeval German Bible is still unknown. Dr. Ludwig Keller of Münster first suggested in his Die Reformation und die älteren Reformparteien, Leipzig, 1885, pp. 257-260, the hypothesis that it was made by Waldenses (who had also a Romanic version); and he tried to prove it in his Die Waldenser und die deutschen Bibelübersetzungen, Leipzig, 1886 (189 pages). Dr. Hermann Haupt, of Würzburg, took the same ground in his Die deutsche Bibelübersetzung der mittelalterlichen Waldenser in dem Codex Teplensis und der ersten gedruckten Bibel nachgewiesen, Würzburg, 1885 (64 pages); and again, in self-defense against Jostes, in Der waldensische Ursprung des Codex Teplensis und der vor-lutherischen deutschen Bibeldrucke, Würzburg, 1886. On the other hand, Dr. Franz Jostes, a Roman Catholic scholar, denied the Waldensian and defended the Catholic origin of that translation, in two pamphlets: Die Waldenser und die vorlutherische Bibelübersetzung, Münster, 1885 (44 pages), and Die Tepler Bibelübersetzung. Eine zweite Kritik, Münster, 1886 (43 pages). The same author promises a complete history of German Catholic Bible versions.

Luther's Qualifications. Luther had a rare combination of gifts for a Bible translator: familiarity with the original languages, perfect mastery over the vernacular, faith in the revealed word of God, enthusiasm for the gospel, unction of the Holy Spirit. A good translation must be both true and free, faithful and idiomatic, so as to read like an original work. This is the case with Luther's version. Besides, he had already acquired such fame and authority that his version at once commanded universal attention.

Besides the whole Bible, there were numerous German editions of the Gospels and Epistles (Plenaria), and the Psalter, all made from the Vulgate.
