And yet another Imperial Diet was convened with reference to these religious disturbances. It was held in Augsburg in the spring of 1530. The emperor was in the zenith of his power. He had overcome his French rival. He had spoiled Rome, humbled the pope, and reorganized Italy. The Turks had withdrawn their armies. And the only thing in the way of a consolidated empire was the Reformation in Germany. To crush this was now his avowed purpose, and he anticipated no great hardship in doing it. He entered Augsburg with unwonted magnificence and pomp. He had spoken very graciously in his invitation to the princes, but it was in his heart to compel their submission to his former Edict of Worms. It behoved them to be prepared to make a full exhibit of their principles, giving the ultimatum on which they proposed to stand. Luther had been formulating articles embodying the points adhered to in his reformatory teachings. He had prepared one set for the Marburg Conference with the Swiss divines. He had revised and elaborated these into the Seventeen Articles of Schwabach. He had also prepared another series on abuses, submitted to the Elector John at Torgau. All these were now committed to Melanchthon for careful elaboration into complete style and harmony for use at the Diet. Luther assisted in this work up to the time when the Diet convened, and what remained to be done was completed in Augsburg by Melanchthon and the Lutheran divines present with him. Luther himself could not be there, as he was a dead man to the law, and by command of his prince was detained at Coburg while the Diet was in session. The first act of the emperor was to summon the protesting princes before him, asking of them the withdrawal of their Protest. This they refused. They felt that they had constitutional right, founded on the decision of Spire, to resist the emperor's demand; and they did not intend to surrender the just principles put forth in their noble Protest. They celebrated divine service in their quarters, led by their own clergy, and refused to join in the procession at the Roman festival of Corpus Christi. This gave much offence, and for the sake of peace they discontinued their services during the Diet. At length they were asked to make their doctrinal presentation. Melanchthon had admirably performed the work assigned him in the making up of the Confession, and on the 25th day of June, 1530, the document, duly signed, was read aloud to the emperor in the hearing of many.
