Schaff, Philip. History of the Reformation. «The most important example of dogmatic influence in Luther’s version is the famous interpolation of the word alone in Rom. 3:28 (allein durch den Glauben), by which he intended to emphasize his solifidian doctrine of justification, on the plea that the German idiom required the insertion for the sake of clearness.464 But he thereby brought Paul into direct verbal conflict with James, who says (James 2:24), "by works a man is justified, and not only by faith" ("nicht durch den Glauben allein"). It is well known that Luther deemed it impossible to harmonize the two apostles in this article, and characterized the Epistle of James as an "epistle of straw," because it had no evangelical character ("keine evangelische Art").»
