A Critical Estimate of Luther's Version. Luther's version of the Bible is a wonderful monument of genius, learning, and piety, and may be regarded in… - Philip Schaff

Progress of his Version. Luther was gradually prepared for this work. He found for the first time a complete copy of the Latin Bible in the University Library at Erfurt, to his great delight, and made it his chief study. He derived from it his theology and spiritual nourishment; he lectured and preached on it as professor at Wittenberg day after day. He acquired the knowledge of the original languages for the purpose of its better understanding. He liked to call himself a "Doctor of the Sacred Scriptures."

Luther could not be ignorant of this mediaeval version. He made judicious use of it, as he did also of old German and Latin hymns. Without such aid he could hardly have finished his New Testament in the short space of three months. But this fact does not diminish his merit in the least; for his version was made from the original Hebrew and Greek, and was so far superior in every respect that the older version entirely disappeared. It is to all intents a new work.

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.
