fall, on free will, on the cause of sin, and on original sin, passed without difficulty. The article on justification encountered great opposition, especially from Eck, but an agreement was finally arrived at; neither Elector John Frederick nor Luther were satisfied with this article. With respect to the articles on the doctrinal authority of the Church, the hierarchy, discipline, sacraments, etc., no agreement was possible, and they were all passed over without result. On 31 May the book, with the changes agreed upon and nine counter-propositions of the Protestants, was returned to the Emperor. In spite of the opposition of Mainz, Bavaria, and the Imperial legate, Charles V still hoped for an agreement on the basis of the articles which had been accepted by both parties, those in which they differed being postponed to a later time.
