The effect of it upon the assembly was indescribable. Many of the prejudices and false notions against the Reformers were effectually dissipated. The enemies of the Reformation felt that they had solemn realities to deal with which they had never imagined. Others said that this was a more effectual preaching than that which had been suppressed. "Christ is in the Diet," said Justus Jonas, "and he does not keep silence. God's Word cannot be bound." In a word, the world now had added to it one of its greatest treasures--the renowned and imperishable AUGSBURG CONFESSION. Luther was eager for tidings of what transpired at the Diet. And when the Confession came, as signed and delivered, he wrote: "I thrill with joy that I have lived to see the hour in which Christ is preached by so many confessors to an assembly so illustrious in a form so beautiful." Even Reformed authors, from Calvin down, have cheerfully added their testimony to the worth and excellence of this magnificent Confession--the first since the Athanasian Creed. A late writer of this class says of it that "it best exhibits the prevailing genius of the German Reformation, and will ever be cherished as one of the noblest monuments of faith from the pentecostal period of Protestantism." The Romanists attempted to answer the noble Confession, but would not make their Confutation public. Compromises were proposed, but they came to naught. The Imperial troops were called into the city and the gates closed to intimidate the princes, but it resulted in greater alarm to the Romanists than to them. The confessors had taken their stand, and they were not to be moved from it. The Diet ended with the decision that they should have until the following spring to determine whether they would submit to the Roman Church or not, and, if not, that measures would then be taken for their extermination. THE LEAGUE OF SMALCALD. The emperor's edict appeared November 19th, and the Protestant princes at once proceeded to form a league for mutual protection against attempts to force their consciences in these sacred matters. It was with difficulty that the consent of Luther could be obtained for what, to him, looked like an arrangement to support the Gospel by the sword. But he yielded to a necessity forced by the intolerance of Rome. A convention was held at Smalcald at Christmas, 1530, and there was formed the _League of Smalcald_, which planted the political foundations of Religious Liberty for our modern world. By the presentation of the great Confession of Augsburg, along with the formation of the League of Smalcald, the cause of Luther became embodied in the official life of nations, and the new era of Freedom had come safely to its birth. Long and terrible storms were yet to be passed, but the ship was launched which no thunders of emperors or popes could ever shatter.[17]
