Particular stress must here be laid on the false mysticism in which Luther was then entangled, and his free use of the fanciful language of certain of the mystics. Luther’s states had, however, nothing in common with those described in somewhat similar words by the healthier mystics, viz. the sore trial of the Mount of Olives through which the soul passes owing to the complete withdrawal of consolation. He, however, imagines he sees himself portrayed not only in such descriptions of the mystics, but also in mystical passages in the Psalms over which, at this time of change, he was fond of brooding. David’s cries ring in his ears; his experience of the hell in which the soul must dwell, of the life which draws nigh to hell, of the bones which are banished to the gate of hell, of the sinking into a dark sea, into the bowels of the earth under the heaped-up weight of endless misery.

It must also be borne in mind that the Monk, with his pseudo-mystical ideas, cherished a gloomy conception of God, and held the terrible doctrine of the absolute predestination of the damned. Having wandered away from the Catholic teaching, with his views on man’s lack of free will, and the theory of arbitrary imputation by God, he found no answer in his troubled conscience to the question which weighed him down, namely, how to arrive at the assurance of a Gracious God. Confusion and interior pangs of conscience for a while gained the upper hand.

Lastly, his peculiar morbid tendency to fear must also be taken into account, for it afforded an opportunity to the Tempter to add to his confusion by raising difficulties regarding the deficiencies of his new, self-chosen theology.

Adolph Hausrath in his Life of Luther even speaks of periodical mental disturbances from which he suffered during the time he was a monk; the disturbing power inherent in the monastic practices, so he says, took possession of his sensitive nature with its strong feelings; Luther only escaped the danger of going mad by bravely bursting the fetters of the monastic Rule and the Popish Faith. In the strong inward combats which Luther endured at a later date Hausrath recognises a return of this affliction. In his second edition he has toned down this view of Luther’s periodical attacks of mental illness out of regard for the objections which had, not without reason, been urged against his statement. In Luther’s case, however, there is no reason for assuming any “monkish mental disease,” nor can he be proved to have suffered from any disturbance whatever of his mental functions at any time of his life.[972] But if we take it that the night of the soul which he passed through, whether in the monastery or during his later struggle, had at its basis a peculiar physico-psychic disposition revealing a want of normal inward stability, then we can perhaps easily explain some other strange and at first blush inexplicable phenomena which his case presents.

At any rate, the fundamental new dogma of the assurance of salvation was not the product of a clear, quiet, calm atmosphere of soul. It was born amidst unbearable inward mental confusion, and was a frantic attempt at self-pacification on the part of the Wittenberg Doctor whose active but unstable mind had already left the true course.

It is of interest and helps us to reach a right understanding of the Tower Experience, to follow the change of view regarding assurance of salvation which is apparent in Luther’s statements and writings in the latter months of 1518 and beginning of 1519.

At the time when, in October, 1518, Luther, a prey to other anxieties, stood before Cardinal Cajetan at Augsburg, he was already making great strides towards the new and consoling dogma of faith alone, moved thereto by indignation at the censure which one of his propositions had called forth. He says to Cardinal Cajetan in his explanation of the second of the assertions which he was required to withdraw, that it was incorrect to speak of it as “a new and false theology that no one can be justified except by faith, and that it is necessary to hold it as certain in faith that one is justified, and not in any way to doubt the obtaining of grace, because whoever doubts or is uncertain is no longer justified, but is rejecting grace.”[973]

He attempts to prove this first as regards Confession. The principal thing is to believe the words of Christ: “Whatsoever thou shalt loose,” etc., i.e. by applying the words to oneself; “under pain of eternal damnation and to avoid committing a sin of unbelief,” it is necessary to believe this; this faith is the only disposition for the sacrament and no work whatever serves as a preparation.[974] No one could receive grace who doubted of its reception; but, if we believed, then we received everything in the sacrament. The belief that we receive a personal remission of sin is, according to St. Bernard, the testimony of the Holy Ghost in our heart; this, according to the same Father, is expressed in Romans iii. 28: “We hold that a man is justified by Faith without the works of the law.” Let Cardinal Cajetan, he says finally—after quoting a great number of biblical passages having no bearing on the matter in hand—show him how he is to understand in any other way all these texts from the Divine utterances.

What is remarkable is, however, that, during his trial at Augsburg, he allows Confession and Absolution to recede further into the background than in the Resolutions; he no longer speaks of the above-mentioned magical production of the personal assurance of salvation, by the formula of absolution, as by the testimony of another; he now holds the absolute certainty of justification to be present by faith even before this, whenever a man is willing to submit himself, according to his instructions, to the Sacrament of Penance.[975] Thus faith alone and the assurance of salvation were already present. The principal difficulty, however, as he admits below (p. 389 f.), still troubled his mind. This was the Justice of God, which haunted his conscience, though it did not hinder his going forward.
