them read this book, and then tell me if our theology is new; for this book is not new."[253] But if Luther took all the good that was in mystical theology, he took not the bad that was in it. The great error in mysticism is, to overlook a free salvation. We are going to see a remarkable example of the purity of Luther's faith. [252] "Illis præfero mysticos et Biblia." (Luth. Ep. i, 107.) [253] Die Deutsche Theologie, Strasbourg, 1519; Præf. Luther, possessed of a tender and affectionate heart, was desirous to see those whom he loved in possession of the light which had guided him into the paths of peace; and availed himself of all the opportunities which he had, as professor, preacher, and monk, as well as of his extensive correspondence, to communicate his treasure to others. One of his old brethren of the convent of Erfurt, the monk George Spenlein, was then in the convent of Memmingen. After having spent some time at Wittemberg, Spenlein had asked the doctor to sell different articles which he had left, viz., a tunic of Brussels cloth, a work of a doctor of Isenach, and a monk's frock. Luther carefully executed this commission. "I have received," said he to Spenlein, in a letter, 7th April 1516, "a florin for the tunic, half a florin for the book, and a florin for the frock, and have remitted the whole to the father-vicar," to whom Spenlein owed three florins. But Luther passes quickly from this account of monastic spoils to a more important subject. "I should like much," says he to friar George, "to know how it is with your soul. Is it not weary of its own righteousness? does it not breathe at length and confide in the righteousness of Christ? In our day pride seduces many, especially those who do their utmost to become righteous. Not comprehending the righteousness which is freely given us of God in Christ Jesus, they would stand before him by their merits. But that cannot be. When you lived with us you were in this error, as I also was. I am still constantly fighting with it; and have not yet completely triumphed.
