Nevertheless Luther himself was affrighted at the theory of faith alone, and imputation. He feared lest he should be reproached with setting good works aside with his doctrine of imputed merit. He therefore explains in self-defence that he did not desire a bare faith; “the hypocrites and the lawyers” thought they would be saved by such a faith, but according to Paul’s words a faith was requisite by which we “approach Christ” (“_per quem habemus accessum per fidem_,” Rom. v. 2). Those are therefore in error who go forward in Christ with over-great certainty, but not by faith; as though they would be saved by Christ, for not doing anything themselves and giving no sign of faith. These possess too much faith, or, better still, none at all. Both must exist: “by faith” and “by Christ”; we must do and suffer gladly all that we can in the faith of Christ, and yet account ourselves in all things unprofitable servants, and only through Christ alone think ourselves able to go to God. For the object of works of faith is to make us worthy of Christ and of the refuge and protection of His righteousness.”[215] With this is connected Luther’s insistence on the necessity of invoking God’s grace in order that we may be able to fight against our passions and to bring forth good works, and in order that the passions, which in themselves are sin, may not be imputed by God.[216] Thus can “the body of sin be destroyed” and the “old man overcome.”[217] Luther admits, though with hesitation and in contradiction with himself, works which prepare us for justification.[218] In spite of everything, in this first stage of his development, justification appears to him uncertain. He declares in so many words: “We cannot know whether we are justified and whether we believe”; and he can only add rather lamely: “we must look upon our works as works of the Law and be, in humility, sinners, hoping only to be justified through the mercy of Christ.”[219] He has no “joyful assurance of salvation”—which, in fact, had no place whatever in the new teaching as expounded by Luther himself—and its name is always drowned by the loud cry of sin. Even saints, on account of the sin which still clings to them, do not know whether they are pleasing to God. If they are well advised, they beg solely for the forgiveness of their sin which lies like lead on their conscience. “That is,” the mystic explains, “the wisdom which is hidden in secret” (“_abscondita in mysterio_”), because our righteousness “being entirely dependent on God’s decree remains unknown to us.”[220]
