In 1514 we hear Luther asserting, that of the three vices, sensuality, anger and pride, pride was the most difficult to overcome, a warning which his own experience had confirmed all too surely. “This vice,” he complains, “arises even from victory over the other vices.”[760] One wonders whether he is speaking here from personal experience.

We may ask a similar question with regard to the two other faults mentioned by him, anger and sensuality. Putting aside anger, the effects of which upon himself he frequently admits, we find that he also gives an answer concerning the third temptation. He writes in 1519 of the experiences of his earlier years with regard to sensuality: “It is a shameful temptation, I have had experience of it. You yourselves are, I fancy, not ignorant of it. Oh, I know it well, when the devil comes and tempts us and excites the flesh. Therefore let a man consider well and prove himself whether he is able to live in chastity, for when one is on heat, I know well what it is, and when temptation then comes upon a man he is already blind,” etc.[761]

In his later years he also refers to the “very numerous temptations” which he underwent at the monastery, and of which he complained to his confessor; the more he fought against them, the stronger they became.[762]

What he says of falling into sin is very instructive from the psychological point of view. It serves as a stepping-stone to his views on penance.

“Even to-day,” he writes in his Commentary on Romans where he deals with hardened sinners, “God allows men to be tempted by the devil, the world and the flesh until they are in despair, choosing thus to humble His elect and lead them to put their trust in Him alone without presuming upon their own will and works. Yet He often, especially in our day, incites the devil to plunge His elect into dreadful sins beneath which they languish, or at least allows the devil ever to hinder their good resolutions, making them do the contrary of what they wish to do, so that it becomes plain to them that it is not they who will or perform what is good. And yet by means of all this God leads them against their expectations [to His grace] and sets them free while they are sighing because they desire and do so much that is evil, and are unable to desire and do the good they would. Yea, it is thus that God manifests His strength and that His name is magnified over the whole earth.”[763] This passage is scored in the margin of the original MS. Was it his intention to include himself among those who are always hindered by the devil from doing what is good, or even among those whom he plunges into dreadful sins, who despair and are then at last led by God to His grace and become promoters of the glory of His name? A certain resemblance which this description bears to other passages in which he recounts his temptations, despair and supposed deliverance and election makes this seem possible, though it is by no means certain.

We are more inclined to apply to him a remarkable description, which he gives in another passage of the Commentary on Romans, of the devil’s action on a man whom he wishes to lead astray. Man’s fall under the bondage of sin and his resuscitation by grace engage his attention often and with a singular intensity, but generally speaking he makes no mention of contrition or satisfaction, but only of a covering over with the righteousness of Christ. The description in question, given in eloquent language, is based on the well-known passage in Romans iii. 28: “We account a man to be justified by faith without the works of the law.” This is the verse in which Luther later, in his translation, interpolated the word “alone” (“by faith alone”), but on which he does not as yet bestow any particular attention. On the contrary, he commences his exposition of this text with the statement: “Righteousness must, indeed, be sought by works, but these are not the works of the law because they are performed by grace and in faith.”[764]

He goes on to mention four classes of men who are led away by the devil in their esteem and practice of works.[765] The first he draws away from all good works and entangles in manifest sin. The second, who think themselves righteous, he makes tepid and careless. The third, also righteous in their own eyes, he renders over-zealous and superstitious, so that they set themselves up as a class apart and despise others; they have been mentioned over and over again in the above pages, in recounting his warfare with the Observants, the “Spirituals,” the proud self-righteous, etc.

The fourth and last class might possibly include himself.

“The fourth class consists of those who, at the instigation of the devil, desire to be free from any sin, pure and holy. But as they, nevertheless, feel that they commit sin and that all they do is tainted with evil, the devil terrifies them to such an extent with fear of the judgments of God and scruples of conscience that they almost despair. He is acquainted with each one’s disposition and tempts him accordingly. As they are zealous in the pursuit of righteousness the devil is unable to turn them aside from it so readily. Therefore he sets himself to fill them with enthusiasm, so that they wish to free themselves too speedily from all trace of concupiscence. This they are unable to do, and consequently he succeeds in making them sad, downcast and faint-hearted, yea, even in causing them unendurable anxiety of conscience and despair.”
