Since Luther had dedicated the afore-mentioned Tessaradecas conolatoria to the reigning Prince,[4] he now, probably on Spalatin's recommendation, dedicated the Treatise on Good Works to his brother John, who afterward, in 1525, succeeded Frederick in the Electorate. There was probably good reason for dedicating the book to a member of the reigning house. Princes have reason to take a special interest in the fact that preaching on good works should occur within their realm, for the safety and sane development of their kingdom depend hugely upon the cultivation of morality on the part of their subjects. Time and again the papal church had commended herself to princes and statesmen by her emphatic teaching of good works. Luther, on the other hand, had been accused—like the Apostle Paul before him (Rom. 3:31)—that the zealous performance of good works had abated, that the bonds of discipline had slackened and that, as a necessary consequence, lawlessness and shameless immorality were being promoted by his doctrine of justification by faith alone. Before 1517 the rumor had already spread that Luther intended to do away with good works. Duke George of Saxony had received no good impression from a sermon Luther had delivered at Dresden, because he feared the consequences which Luther's doctrine of justification by faith alone might have upon the morals of the masses. Under these circumstances it would not have been surprising if a member of the Electoral house should harbor like scruples, especially since the full comprehension of Luther's preaching on good works depended on an evangelical understanding of faith, as deep as was Luther's own. The Middle Ages had differentiated between fides informis, a formless faith, and fides formata or informata, a formed or ornate faith. The former was held to be a knowledge without any life or effect, the latter to be identical with love, for, as they said, love which proves itself and is effective in good works must be added to the formless faith, as its complement and its content, well pleasing to God. In Luther's time every one who was seriously interested in religious questions was reared under the influence of these ideas.[5]
