The Elector seems also to have enjoined silence on Luther with respect to the articles until they had been approved at Wittenberg. For in his letter to Spalatin, of December 15, 1536, Luther wrote: "But you will keep these matters [his journey to Wittenberg to discuss the articles] as secret as possible, and pretend other reasons for your departure. _Sed haec secreta teneas quantum potes, et finge alias causas abeundi._" (St. L. 21b, 2135.) December 11 the Elector again called attention to the articles, desiring that Amsdorf, Agricola, and other outside theologians be called to Wittenberg at his expense to take part in the discussion. Shortly after, Luther must have finished the articles. The numerous changes and improvements appearing in the original manuscript, which is still preserved in the Heidelberg library, show how much time and labor he spent on this work. Concluding his articles, Luther says: "These are the articles on which I must stand, and, God willing, shall stand even to my death; and I do not know how to change or to yield anything in them. If any one wishes to yield anything, let him do it at the peril of his conscience." (501, 3.) Toward the close of the year Luther submitted the draft to his colleagues, Jonas, Bugenhagen, Cruciger, Melanchthon, and those who had come from abroad, Spalatin, Amsdorf, and Agricola. After thorough discussion it was adopted by all with but few changes, _e.g._ regarding the adoration of the saints, concerning which Luther had originally said nothing. (Kolde, 44.) Spalatin reports that all the articles were read, and successively considered and discussed. The Elector had spoken also of points in which a concession might be possible. In the discussion at Wittenberg, Spalatin mentioned as such the question whether the Evangelicals, in case the Pope would concede the cup to them, should cease preaching against the continuance of the one kind among the Papists; furthermore, what was to be done with respect to ordination and the adiaphora. Luther had not entered upon a discussion of these questions, chiefly, perhaps, because he was convinced that the council would condemn even the essential articles. (Compare Melanchthon's letter of August 4, 1530, to Campegius, _C. R._ 2, 246.) After the articles had been read and approved, Spalatin prepared a copy (now preserved in the archives at Weimar), which was signed by the eight theologians present, by Melanchthon, however, with the limitation that the Pope might be permitted to retain his authority "iure humano," "in case he would admit the Gospel." Perhaps Melanchthon, who probably would otherwise have dissimulated, felt constrained to add this stricture on account of the solemn demand of the Elector that no one should hide any dissent of his, with the intention of publishing it later.
