Amongst the admonitions addressed to Luther at an early date by men of weight, that of Zaccaria Ferreri, the Papal Legate in Poland, written in 1520 and published in 1894, is particularly noteworthy. From the self-love and arrogance which he found displayed in Luther’s character he proves to him that his could not be the work of God: “Do open your eyes and see into what an abyss of delusion you are falling. You seem to fancy that you alone are in the sunlight and that all the rest of the world is seated in the darkness of night.... You reproach Christianity with groping about in error for more than a thousand years; in your madness you wish to appear wiser and better than all other mortals put together, to all of whom you send forth your challenge. Rest assured your opponents are not so dull-witted as not to see through your artfulness and to perceive the inconsistency and frivolity of your doctrines.” Ferreri also addressed the following appeal to Luther: “If you are determined to cast yourself into the abyss of death, at least take pity on the unfortunate people whom you are daily infecting with your poison, whose souls you are destroying and dragging along with you to perdition. The Almighty will one day require of you their blood which you have drunk, and their happiness which you have destroyed.”[504] * * * * * Such voices from the past help to make us alive to the importance of the question which forms the subject of the present section. Luther’s own ethical practice when defending the divinity of his mission, more particularly his doctrine of the forgiveness of sins, against all doubts and “temptations” which occurred to him, affords us, however, the best and clearest insight into his moral standards. Here his moral attitude appears in a most singular light. We may preface what follows with some words of the Protestant historian Gottlieb Jacob Planck (†1833): “When it is necessary to lay bare Luther’s failings, an historian should blush to fancy that any excuse is required for so doing.”[505] “Temptations” to doubt were not uncommon in Luther’s case and in that of his friends. He accordingly instructs his disciples to combat them and to regain their lost equanimity by the same method which he himself was in the habit of employing. Foremost amongst these instructions is one addressed to his pupil Hieronymus Weller of Molsdorf, a native of Freiberg, who, whilst at Wittenberg, had, under Luther’s influence, relinquished the study of the law for that of theology. He was received into Luther’s household as a boarder in 1527, and in 1535, after having secured his Doctorate of Theology, he was still resident there. He was one of the table-companions who took notes of Luther’s “Table-Talk.” This young man was long and grievously tormented with anxiety of mind and was unable to quiet, by means of the new Evangel, the scruples of conscience which were driving him to despair.
