Mosellanus, by order of the duke, mounted a pulpit, to remind the theologians of the manner in which the discussion was to be carried on. "If you begin to quarrel," said the orator to them, "what difference will there be between a theological disputant and a swaggering duellist? What is victory here but just to recall a brother from his error?... Each, it would seem, should be more desirous to be conquered than to conquer."[73] [73] Seckend., p. 209. [Sidenote: PORTRAITS OF LUTHER, CARLSTADT, ECK.] At the conclusion of the address, sacred music echoed along the aisles of the Pleissenberg, the whole assembly knelt down, and the ancient hymn of invocation to the Holy Spirit, "Veni, Sancte Spiritus," was sung. Solemn hour in the annals of the Reformation! The invocation was thrice repeated; and, while the solemn chant was pealing, the defenders of the ancient, and the champions of the new doctrines, the men of the Church of the middle ages, and those desirous of re-establishing the Church of the apostles, mingling together without distinction, in lowly attitude bent their faces to the ground. The ancient tie of one single communion still united all these different minds, and the same prayer still proceeded from all these lips as if a single heart had dictated it. These were the last moments of external lifeless unity for which a new spiritual living unity was about to be substituted. The Holy Spirit was invoked in behalf of the Church, and the Holy Spirit was about to answer by a revival of Christendom. When the hymn and prayer were finished, the assembly rose up. The discussion should have now commenced; but, as the hour of noon had arrived, there was an adjournment of two hours. The leading personages who proposed to attend the debate, having dined with the duke, returned with him after dinner to the castle hall, which was filled with spectators. Meetings of this description were the public assemblies in which the representatives of the age discussed questions of general and engrossing interest. The orators were soon at their post. That a better idea may be formed of them, we will give their portraits as drawn by one of the most impartial witnesses of the debate.
