A peculiarity of Luther’s teaching on the Sacrament is to be found in his two theories of Impanation and Ubiquity. Impanation, viz. the opinion that the substance of the bread persists in the Sacrament and that Christ is present together with the bread, served him as a means to escape the Catholic doctrine of a change of substance (Transubstantiation). With the help of the theory of Ubiquity which affirmed the presence everywhere of the Body of Christ, he fancied he could extricate himself from certain difficulties raised by opponents of the Sacrament. The history of both opinions presents much that is instructive. Here, however, we shall consider only the second, viz. the ubiquity of Christ’s Body.

The theory of the omnipresence of the Body of Christ which Luther reached together with his doctrine of the Supper, like his other theory of the faith of infants, shows plainly not only of how much his imagination was capable, but also what curious theses he could propound in all calmness and serenity. Thus we hear him asserting that the Redeemer, the Lord of Creation, is present, in His spiritualised Body, everywhere and penetrates all things! He is present bodily at the right hand of God according to the Scriptures; but the right hand of God is everywhere, hence also in the consecrated Bread and Wine lying on the altar; consequently the Body and Blood of Christ must be there too.[1739] To the question how this comes about, he replies: “It is not for us to know,” nor does reason even understand how God can be in every creature.

Much more important is it, so he says, that we should learn to seize, grasp and appropriate this ever-present Christ. “For though Christ is everywhere present, He does not everywhere allow Himself to be seized and laid hold of.... Why? Because it is one thing for God to be present and another for Him to be present to you. He is present to you then when He pledges His Word to it and binds Himself by it and says: Here you shall find Me. When you have His Word for it, then you can truly seize Him and say: Here I have Thee, as Thou hast said.”[1740] In this way Christ assures us of His presence in the Sacrament, and invites us, so Luther teaches, to partake of Him in the Bread of the Supper. This, however, is practically to explain away the presence of Christ in the Bread (to which Luther adheres so firmly) and to dissolve it into a purely subjective apprehension. Nevertheless, at least according to certain passages, he was anxious to see the Sacrament adored and did not hesitate to do so himself.[1741]

To the belief that Christ’s Body is truly received in Communion he held fast, as already stated, till the end of his life.

The report, that, in the days of extreme mental tension previous to his last journey to Eisleben, he abandoned the doctrine of the Real Presence, hitherto so passionately advocated, in order to conciliate the Zwinglians or Melanchthonians, is a fable, put into circulation by older Protestant writers.[1742] In view of the proofs, met with up to the very last, of his belief to the contrary, we may safely dismiss also the doubtful account to be mentioned directly which seems to speak in favour of his having abandoned it.

Luther’s “Kurtz Bekentnis” of September, 1544, certainly was true to his old standpoint and showed that he wished “the fanatics and enemies of the Sacrament, Carlstadt, ‘Zwingel,’ Œcolampadius, Stinkfield [Schwenkfeld] and their disciples at Zürich, or wherever else they be, to be sternly condemned and avoided.”[1743] In his last sermon at Wittenberg on Jan. 17, 1546, he warned his hearers against reason, that “fair prostitute and devil’s bride,” and, indirectly, also against the Sacramentarians and those who attacked his doctrine of the Supper. George Major relates that when he was sent, on Jan. 10, 1546, by Luther to the religious conference at Ratisbon he found scribbled on his door these words: “Our professors must be examined on the Supper of the Lord”; Luther also admonished him not to endeavour to conceal or pass over in silence belief in the Real Presence. On his journey Luther said much the same in the sermons he delivered at Halle and Eisleben; even in his last sermon at Eisleben we find the Sacramentarians described as seducers of mankind and foes of the Gospel.[1744]

That Luther changed his opinion is the purport of a communication, which, after his death, Melanchthon is said to have made to A. R. Hardenberg, a friend of his. Hardenberg speaks of it in a document in his own handwriting preserved in the Bremen municipal archives. There he certainly affirms that Melanchthon had told him how that Luther, before his last journey, had said to him: People have gone too far in the matter of the Supper; he himself had often thought of writing something so as to smooth things down and thus allow the Church again to be reunited; this, however, might have cast doubts on his doctrine as a whole; he preferred therefore to commend the case to God; Melanchthon and the others might find it possible to do something after his death.[1745]—Evidently it is our duty to endeavour to understand and explain this account, however grounded our suspicions may be. One recent Protestant writer has justly remarked: “There must be something behind Hardenberg’s testimony”[1746]; and another, that it “cannot be simply set aside.”[1747]

J. Hausleiter, in 1898, seems to have given the most likely explanation of it:[1748] After Luther’s death Amsdorf complained bitterly that the Wittenberg edition of Luther’s German works, then in the press, had not preserved the real Luther undefiled; he pointed out, that, in the second volume, Luther’s violent attack on the Sacramentarians had been omitted where (at the end of the work “Das diese Wort Christi ‘Das ist mein Leib, etce.,’ noch fest stehen,” 1527) he had said that the devil with the help of Bucer and his denial of the Sacrament had “smeared his filth” over Luther’s books; that Bucer was a “sly, slippery, slimy devil”; where Luther had spoken of Bucer’s “poisonous malice, murderous stabs and arch-scoundreldom,” thanks to which he had “defiled, poisoned and defamed” Luther’s teaching, and where a protest was registered against the assertion that “to begin with,” Philip too had taught the same as the Sacramentarians, viz. that there is “nothing but bread in the Lord’s Supper.”[1749] It was known that those pages had been suppressed in the new edition at Luther’s own hint. This was stated by George Rörer, Luther’s former assistant, who supervised the correction. He said, “he did this with the knowledge and by the request and command of Luther, because M. Bucer, who had there been so severely handled as a notable enemy of the Sacrament, had since been converted.” Of any real conversion of Bucer there can be no question, but as he was then doing good work at Ratisbon in the interests of the new Evangel it may be that Luther—perhaps moved thereto by his Electer at the instance of the Landgrave of Hesse—consented to display such indulgence. This may well have formed the subject of the communication Hardenberg received from Melanchthon, only that the one or the other, or possibly both, in the interests of the movement hostile to Luther’s Sacramental teaching, distorted and exaggerated the facts of the case, and thus gave rise to the legend of Luther’s change of views.

Support for it may also have been seen in the circumstance that Luther, in spite of Melanchthon’s defection on the doctrine of the Sacrament, never broke off his relations with him. In his severe “Kurtz Bekentnis” (1544) he forbore from attacking Melanchthon either openly or covertly. Even in 1545, in the Preface to his own Latin works, Luther bestowed his well-known eulogy on Melanchthon’s “Loci theologici.”[1750] It has been pointed out elsewhere that the services his friend rendered him had been and continued to be too important to allow of Luther’s breaking with him.[1751]
