Here, as everywhere else, the changeableness of Luther’s doctrinal opinions is deserving of notice. The numerous instances where he relinquishes a position previously held and virtually betakes himself to another, are scarcely to the credit either of his logic or of his foresight. Such wavering and groping hither and thither is the stamp of error. In the “Histoire des variations” which might be written on the fate of Luther’s views even during his lifetime, much would be found truly characteristic of them.

One sacramentarian doctrine, which to the end of his life he would never consent to relinquish, was, as we know, the Presence of Christ in the Supper. And relentless as he was in combating the Sacrifice of the Mass (see below, p. 506 ff.), yet he insisted steadfastly on the literal acceptance of Christ’s words of institution: “This is My Body.”

His Teaching on the Supper.

Luther’s retention of the Presence of Christ in the Eucharist may to some extent be explained by the influence which, side by side with the Bible, tradition and the authority of the Church still exercised over him, at least on such points as did not call for modification on account of his new doctrine of Justification. He had grown up in this faith, and was accustomed to give practical proof of it even when on other scores he had already broken with the Church. In this matter Scripture presented no difficulty. Had he shared Zwingli’s rationalistic leanings it is likely that, like him, he might have sought for some other interpretation of the words of institution than the obvious and literal one. It is also possible that the mysticism to which he was addicted in early years may have contributed to make him acknowledge the “mysterium tremendum” of the Sacrament, as he terms it in the language of olden days.

It is true there came a time—according to him the year 1519-1520—when he felt strongly tempted to throw the Sacrament overboard, because, as he says in the well-known words, “I could thus have given a great smack in the face to Popery.” At that time I “wrestled and struggled and would gladly have escaped.” But from the plain text of the Bible, he had, so he declares, been unable to free himself. This statement, which is on the whole worthy of belief, we find in “Eyn Brieff an die Christen zu Straspurg” which he published in 1525, and it is further corroborated by the fact, that he there refers to two men who had been anxious to move him to the denial of the Presence of Christ, but who had failed to convince him. The two, whose names he does not mention, were probably Cornelius Hendriks Hoen, a Dutchman, and Franz Kolb of Baden, whose letters to Luther, in 1522 and 1524, trying to induce him to accept the Zwinglian sense of the Sacrament, still exist.[1735]

When Carlstadt began his attack on the Real Presence, this, in view of the then situation, so Luther declares in his letter to the people of Strasburg, merely “confirmed his opinion.” “Even had I not believed it before, I should at once have known that his opinions were nought, because of his worthless, feeble stuff, devoid of any Scripture and based only on reason and conceit.” Offended vanity and annoyance with Carlstadt were here not without their effect on Luther; to deny this would argue a poor acquaintance with Luther’s psychology. It is true that the arguments of his opponent were very weak; it was not without reason that Luther speaks of his “stuff and nonsense” and “ridiculous tales.” He ranks the objections of the two letter-writers mentioned above higher than the proofs adduced by Carlstadt; at least they “wrote more skilfully and did not mangle the Word quite so badly.” Luther was, however, tactless enough to give the Strasburgers a glimpse of the secondary motives which led him to defend the Presence of Christ so strongly and defiantly from that time forward. He complains that Carlstadt was making such an ado as though he wanted “to darken the sun and light of the Evangel,” so “that the world might forget everything that had been taught them by us [by Luther] hitherto.” “I have up till now managed well and rightly in all the main points, and whoever says the contrary has no good spirit; I trust I shall not spoil it in the matter of the externals on which alone prophets such as these lay stress.”[1736]

It is unnecessary to show anew here how Luther’s later defence of the Real Presence in the Eucharist against the Zwinglians contains indubitable evidence in its virulence that Luther felt hurt. This personal element is, however, quite insufficient for one to base upon it any suspicion as to the genuineness of his convictions.

If, on the other hand, we consider the strange and arbitrary form he gave to the doctrine of the Supper, more particularly by insisting that the sole aim and effect of communion is to inspire faith in the personal forgiveness of sins, then his belief in the presence of Christ appears to a certain extent to harmonise with his peculiar theological views. Amidst the storm of his struggle after certainty of salvation the pledge of it which Christ bestows in the Sacrament seems to him like a blessed anchor. That this Body was “given” for us, and this blood shed for us, and that the celebration is in memory of the saving death of Christ, as the very words of institution declare, was frequently brought forward by him as a means to reassure anxious souls. The need of strengthening our faith should, according to him, impel us to receive the Sacrament.

He demands accordingly of others the same traditional faith in the Eucharist in which he found his own stay and support. While clinging to the literal interpretation of the words of the Bible, he, as we already know, is quite ready to appeal to the “dear Fathers” and to the whole of the Church’s past, at least when thereby he hopes to make an impression.[1737] To such lengths does he go in the interests of the confirmation of faith to which he strives to attain by means of this indispensable Sacrament.

He overlooks the fact, however, that his view of the Supper, according to which its only purpose is to be a sign for the stimulating of saving faith, in reality undermines the doctrine of the Real Presence. True to his theory of the Sacrament and of faith he reduces the Supper to an outward sign destined to confirm the forgiveness of sins. One might ask: If it is merely a sign, is so sublime a mystery as the Real Presence at all called for? And, if it is a question of assurance, how can we be rendered secure of our salvation by something which is so far removed above the senses as the belief in the Real Presence of Christ, or by an act which makes such great demands on human reason? Luther’s theory requires a sign which should appeal to the senses and vividly remind the mind of the Redemption and thus awaken faith. This is scarcely the case in the Eucharist where Christ is invisibly present and only to be apprehended by “the Word.” If bread and wine are merely to call forth a remembrance of Christ which inspires faith, then the Zwinglian doctrine of the Sacrament fulfils all that is required. Luther does not face this difficulty, but Protestants were not slow to urge it against him.[1738]
