Luther was not greatly pleased with their coming, for he had read the epistle already mentioned, and thought that the opposite party were not seeking a sincere union. However, this does not seem to have been the case, for on the road to Wittenberg they had visited FREDERICK MYCONIUS at Gotha, who soon led them to converse on the Lord's Supper, and found them inclined to unite with the Wittenbergers upon a proper basis. This he relates in a detailed narrative of the proceedings of the Convention. MENIUS also had understood this to be the case, and they both informed Luther and Melanchthon of it. Early on the 22d of May, Bucer and Capito visited Luther, but the convention did not begin until three o'clock in the afternoon. One side was represented by Luther, Pomeranus, Jonas, Cruciger, Melanchthon, Menius, Myconius, Weller, and Rorarius; the other merely by Bucer and Capito. Bucer opened the meeting by a lengthy address, in which he particularly expressed his joy on account of this Conference, and stated that this was now the fourth year that he had been laboring to bring about a union. Luther replied, and expressed his disapprobation of the epistle of Zwingli and Oecolampadius, prefaced by a letter from Bucer, which did not at all agree with this union. He believed it would be better to leave matters as they were, than to make this business, which is already bad enough, a hundred times worse by a fictitious form of concord. This of course greatly perplexed Bucer; but in a long speech he again declared that there was no deception in the case, but that the Upper Germans had fully expressed their sentiments, and that the said epistle had been printed against his will, yea, even against his express injunctions; and that his own letter had been written to others during the previous year, and had not been intended for publication. Luther now, in his reply, demanded that they should, _first_ of all, publicly recant their previous opinion as incorrect; and _secondly_, that they would henceforth teach in unison with the Wittenbergers. He began to explain this doctrine at length; but, during this address, he became so feeble, that he was obliged to desist. They did not resume the conference until three o'clock in the afternoon of the next day. Luther insisted upon the two points referred to yesterday, and requested an answer from them. Bucer consented to recant, and confessed in his own name and that of the Swiss, that the bread in the Lord's Supper is truly the body of Christ, and that the wine is truly the blood of Christ; and that the body and blood of Christ, namely, the natural, essential body, are received, not only by the heart, but with the mouth of those who receive it, if worthily, unto salvation, but if unworthily, unto damnation. His friends also, upon Luther's inquiry, expressed themselves to be of the same opinion, and earnestly requested that they might be received in a brotherly manner into such a union, as members of Christ.
