In a letter to Lang—who was also inclined to look with favour on Tauler, the master of German mystic theology—Luther betrays how greatly he was attracted by this writer. In his sonorous, expansive language, he speaks of him as a teacher whose enlightenment was such, that, though utterly unknown in the theological schools, he contains more real theology than all the scholastic theologians of all the universities put together. He also repeatedly assured his hearers that Tauler’s book of sermons had “led him to the spirit.”[198] At that time Luther showed great preference for the exhortations of the German mystics on self-abasement, apathy and abnegation of self. “_Theologia Deutsch_,” that little work of an unknown Frankfort priest of the fourteenth century, which he came across in a MS., so fascinated him that, adding to it a preface and his own name, “Martinus Luder,” he published it in 1516 at Wittenberg. It was the first occasion of his making use of the press; this first edition was, however, incomplete, owing to the state of the MS.; the work was finally reissued complete and under the title which Luther himself had selected, viz. “A German Theologia,” in 1518. In the sub-title of the first edition he had called it a “noble spiritual booklet,” and in the preface had praised it, saying that it did not float like foam on the top of the water, but that it had been brought up from the bottom of the Jordan by a true Israelite.[199] In the first edition he had erroneously attributed the booklet to Tauler; in the second he says it is equal in merit to Tauler’s own writings. Yet, to tell the truth, it is far from reaching Tauler’s high standard of thought. Luther, however, assures us that, next to the Bible and St. Augustine, he can mention no book from which he has learned more of the nature of God, Christ, man and all other things, than from this work. When he forwarded a printed copy of the first edition to Spalatin (December 14, 1516), he wrote, that Tauler offered a solid theology which was quite similar to the old; that he was acquainted with no theology more wholesome and evangelical. Spalatin should saturate himself with Tauler’s sermons; “taste and see how sweet the Lord is, after you have first tasted and seen how bitter is everything that is ourselves.”[200] In addition to the authors mentioned, the mysticism of Pseudo-Dionysius the Areopagite and of Gerard Groot, the founder of the Community of the Brethren of the Common Life, were known to him. That he was, or had been, fond of reading the writings of St. Bernard, we may guess from his many—often misunderstood—quotations from the same. Luther was also well able, whilst under the influence of that inwardness which he loved so much in the mystics, to make his own their truly devotional and often moving language.
