With regard to the “way of the cross” and the “theology of the cross,” which he began to teach as soon as he had lost himself in the maze of mysticism, he explains himself more clearly in the Disputations which he organised at Wittenberg, and which will be dealt with below.[429]

2. Effect of Mysticism on Luther

The study of mysticism was not altogether disadvantageous to Luther, for it proved of use to him in various ways.

First, as regards his grasp of spiritual subjects and their expression in words, Tauler’s simple and heartfelt manner taught him how to clothe his thoughts in popular and attractive dress. The proof of this is to be found in his writings for the people and in several of his more carefully prepared sermons, particularly in the works and sermons of the first period when the mystical influence was still predominant. Also with regard to the common body of Christian belief, so far as he still held fast to the same, several excellent elements of Catholic mysticism stood him in good stead, notwithstanding his inward alienation. The intimate attachment of the mystics to Christ and their longing expectation of salvation through the Lord alone, sentiments which made an immense impression on his soul, notwithstanding the fact that he understood them in a one-sided and mistaken fashion, probably had their share in preserving in him to the very end his faith in the Divinity of Christ and in the salvation He wrought. They also led him to esteem the whole Bible as the Word of God, and to hold fast to various other mysteries which some of the Reformers opposed, for instance, the mysterious presence of Christ in the Sacrament, even though they did not prevent him from modifying these doctrines according to his whim. While Luther retained many of the views rooted in the faith and sentiment of earlier ages, the Rationalism of Zwingli was much more ready to throw overboard what did not appear to be sanctioned by reason; this came out especially in the controversy on the Lord’s Supper. The reason of this was that Zwingli had been trained in the school of a narrow and critical Humanism; of mysticism in any shape or form he knew nothing at all.

Among the advantages which Luther derived from mysticism we cannot, however, reckon, as some have done, his later success against the fanatics; this success was not a result of his having overcome their false mysticism by the true one. By that time he had almost completely given up his mysticism, whether true or false. He certainly met the attacks of the fanatics and Anabaptists by appealing to his own mystical experiences, but that was really a mere tactical, though none the less effective, manœuvre on his part, which, with his ready tongue and pen, he was able to put to excellent account. “Who spoke of spirits?” he says; “I also know the spirit and have had experience of the spirit; I am able, yea, am called, to reveal their delusions.” And in the eyes of many he may certainly have been considered, on account of the “mystical” terrors he had suffered, and to which he frequently referred in public, to be specially fitted to unmask the false spiritualism of his opponents. As a matter of fact, his fears and his mysticism had nothing to do with the real discerning of spirits; they never brought him light, but only darkness. The truth is that, at the time of his contest with the fanatics, he had become more sober, had a clear, practical eye for the mischief of the movement, and regarded it as the highest duty of self-preservation to stamp out the flame of revolt against his patrons and his own teaching. We shall see, however, that the fanatics were, in a certain sense, the children of Luther’s own spirit.

The real good which Luther may have derived from the study of mysticism was far more than counterbalanced by the regrettable results of his notions concerning the “pure myrrh” of passivity, and the desire for nothingness, which at one and the same time involved him in a real labyrinth, and raised his estimation of his own mission to an enormous and dangerous height. He came to fancy himself far superior not only to the Occamists, but to the whole of the secular and regular clergy, the “swarm of religious and priests,” even to all the theologians, and particularly to the Scholastics, those “sow theologians,” who knew nothing of what he was conversant with.

His mysticism had already paved the way for his later belief with regard to his own Divine call to establish the new teaching; it was supported by his views of God’s guidance of the unconscious soul; what he would formerly have regarded as a mistaken road and due to diabolical inspiration was now labelled a godly act.

True and real mysticism could not take root in him because, to start with, the necessary predisposition, concerning which the other mystics and Tauler are agreed, was wanting, viz. above all humility, calmness and that holy indifference, which allows itself to be led by God along the path of the rules of its calling without any ulterior, private aims; peaceableness, composure of mind and zeal in prayer were not his. What mysticism left behind in Luther was scarcely more than the fragrance of its words, without any real fruit. What took root and grew in him was rather the hard wood from which lances are made, ready for every combat that may arise. His mysticism itself gives the impression of being part of the battle which his antagonism to the Occamists led him to give to Scholasticism. Those who contradicted his new ideas—even his brother monks, like the Erfurt philosophers and theologians—appeared to him to be opposed on account of their Scholasticism. The most effective way of escaping or overcoming them seemed to him the replacing of the older theology by another, in which, together with Holy Scripture and St. Augustine, mysticism should occupy a chief place.

By this, however, we do not mean that the mysticism of Luther was merely a fighting weapon. From his letters we may gather that he lived in the belief that his new road would conduct him to a joyous nearness to God.
