Doctrines are taught now which have no affinity with Christ, and only darken our eyes."[2] Again in 1521 he wrote to a friend, words which appear again and again in his letters: "It would be well for us if we thought less about our dogmas and more about the gospel,"[3] or, as he often puts it, "if we made less of dogmatic subtleties and more of Scripture." So far as Humanism was a religious force it was pushing toward a religion of the lay-type, with man himself--man with his momentous will--as the centre of interest. Another important influence was slowly but pervasively filtering down into the life of the people and preparing the way for a religion of greater personal vitality and spiritual inwardness; I mean the testimony of the great mystics. One has only to study the life and writings of such a scholar as Nicolaus Chrypffs--generally called Cusanus, or Nicholas of Cusa--who died shortly before Luther was born,[4] to see what a live force the mystical teaching was even in this period of Renaissance. God is for him, as for his great masters, Plotinus, Erigena, Eckhart, and Tauler, the infinite and indescribable subsoil of the universe, in whose Reality all the roots of life and all the reality of things are grounded. The soul, by nature spiritual and immortal, at its apex rises above the contradictions which lower knowledge everywhere meets and comes into possession, by a "learned ignorance," of Truth itself and into an unspeakable union with God. But it was not merely among scholars like Nicholas that mysticism formed the elemental basis of life and thought; it had, through the circles of the {4} "Brothers of the Common Life,"[5] and through such masterpieces as the _Imitation of Christ_, the _Theologia Germanica_, and the Sermons of Eckhart and of John Tauler, become a part of the spiritual atmosphere which serious-minded men breathed. Every one of the men who belong in my list of "Spiritual Reformers" read and loved "the golden book of German Theology," and most of them knew the other writings of the great fourteenth-century mystics. There are unmistakable evidences of a subtle formative influence from these rich sources, which explains the simultaneous sporadic outbreak of similar views in widely sundered places. There was, thus, abroad at the opening of the Reformation a deep yearning among serious people for a religion of inward experience, a religion based not on proof-texts nor on external authority of any kind, but on the native capacity of the soul to seek, to find and to enjoy the living God who is the Root and Sap of every twig and branch of the great tree of life. The general trend of this mystical tendency, as also of the Humanistic movement, was in the direction of lay-religion, and both movements alike emphasized the inherent and native capacity of man, whose destiny by his free choice is in his own hands.
