Of his principles the following must be borne in mind. Man’s attitude towards things Divine is just that of the dumb, lifeless “pillar of salt into which Lot’s wife was changed”; “he is not one whit better off than a clod or stone, without eyes or mouth, without any sense and without a heart.”[2] Human reason, which ought to govern moral action, becomes in matters of religion “a crazy witch and Lady Hulda,”[3] the “clever vixen on whom the heathen hung when they thought themselves cleverest.”[4] Like reason, so the will too, in fallen man, behaves quite negatively towards what is good, whether in ethics or in religion. “We remain as passive,” he says, “as the clay in the hands of the potter”; freedom there is indeed, “but it is not under our control.” In this connection he refers to Melanchthon’s “Loci communes,”[5] whence some striking statements against free-will have already been quoted in the course of this work.[6]

It is only necessary to imagine the practical application of such principles to perceive how faulty in theory Luther’s ethics must have been. Luther, however, was loath to see these principles followed out logically in practice.

Other theories of his which he applies either not at all or only to a very limited extent in ethics are, for instance, his opinions that the believer, “even though he commit sin, remains nevertheless a godly man,” and, that, owing to our trusting faith in Christ, God can descry no sin in us “even when we remain stuck in our sins,” because we “have donned the golden robe of grace furnished by Christ’s Blood.” In his Commentary on Galatians he had said: “Act as though there had never been any law or any sin but only grace and salvation in Christ”;[7] he had declared that all the damned were predestined to hell, and, in spite of their best efforts, could not escape eternal punishment. (Vol. ii., pp. 268 ff., 287 ff.)

In view of all the above we cannot help asking ourselves, whence the moral incentive in the struggle against the depravity of nature is to come; where, granted that our will is unfree and our reason blind, any real ethical answerableness is to be found; what motive for moral conduct a man can have who is irrevocably predestined to heaven or to hell; and what grounds God has for either rewarding or punishing?

To add a new difficulty to the rest, Luther is quite certain of the overwhelming power of the devil. The devil sways all men in the world to such a degree, that, although we are “lords over the devil and death,” yet “at the same time we lie under his heel ... for the world and all that belongs to it must have the devil as its master, who is far stronger than we and clings to us with all his might, for we are his guests and dwellers in a foreign hostelry.”[8] But because through faith we are masters, “my conscience, though it feels its guilt and fears and despairs on its account, yet must insist on being lord and conqueror of sin ... until sin is entirely banished and is felt no longer.”[9] Yea, since the devil is so intent on affrighting us by temptations, “we must, when tempted, banish from sight and mind the whole Decalogue with which Satan threatens and plagues us so sorely.”[10]

Such advice could, however, only too easily lead people to relinquish an unequal struggle with an unquenchable Concupiscence and an overwhelmingly powerful devil, or, to lose sight of the distinction between actual sin and our mere natural concupiscence, between sin and mere temptation; Luther failed to see that his doctrines would only too readily induce an artificial confidence, and that people would put the blame for their human frailties on their lack of freedom, their ineradicable concupiscence, or on the almighty devil.

How, all this notwithstanding, he contrived to turn his back on the necessary consequences of his own teaching, and to evolve a practical system of ethics far better than what his theories would have led us to expect, is plain from his warm recommendation of good works, of chastity, neighbourly love and other virtues.

In brief, he taught in his own way what earlier ages had also taught, viz. that sin and vice must be shunned; in his own way he exhorted all to practise virtue, particularly to perform those deeds of brotherly charity reckoned so high in the Church of yore. In what follows we shall have to see how far his principles nevertheless intervened, and how much personal colouring he thereby imparted to his system of ethics. In so doing what we must bear in mind is his own way of viewing the aims of morality and practical matters generally, for here we are concerned, not with the results at which he should logically have arrived, but with the opinions he actually held.

The difficulty of the problem is apparent not merely from the nature of certain of his theological views just stated, but particularly from what he thought concerning original sin and concupiscence, which colours most of his moral teaching.

In his teaching, as we already know, original sin remains, even after baptism, as a real sin in the guise of concupiscence; by its evil desires and self-seeking it poisons all man’s actions to the end of his life, except in so far as his deeds are transformed by the “faith” from above into works pleasing to God, or rather, are accounted as such. Owing to the enmity to God which prevails in the man who thus groans under the weight of sin even “civil justice is mere sinfulness; it cannot stand before the absolute demands of God. All that man can do is to acknowledge that things really are so and to confess his unrighteousness.”[11] Such an attitude Luther calls “humility.” Catholic moralists and ascetics have indeed ever made all other virtues to proceed from humility as from a fertile source, but there is no need to point out how great is the difference between Luther’s “humility” and that submission of the heart to God’s will of which Catholic theologians speak. Humility, as Luther understood it, was an “admission of our corruption”; according to him it is our recognition of the enduring character of original sin that leads us to God and compels us “to admit the revelation of the Grace of God bestowed on us in Christ’s work of redemption,” by means of “faith, i.e. security of salvation.” It is possible to speak “only of a gradual restraining of sin,” so strongly are we drawn to evil. We indeed receive grace by faith, but of any infused grace or blotting out of sin, Luther refuses to hear, since the inclinations which result from original sin still persist. Hence “by grace sin is not blotted out.” Rather, the grace which man receives is an imputed grace; “the real answer to the question as to how Luther arrived at his conviction that imputed grace was necessary and not to be escaped is to be found in his own inward experience that the tendencies due to original sin remain, even in the regenerate. This sin, which persists in the baptised, ... forces him, if he wishes to avoid the pitfall of despair ... to keep before his mind the consoling thought ... ‘that God does not impute to him his sin.’”[12]
