One of the most powerful arguments in Luther’s work consisted in the full and detailed description of the Roman money traffic, Germany and other countries being exploited on the pretext that contributions were necessary for the administration of the Church. Luther had drawn his information on this subject from the writings of the German Neo-Humanists, and from a certain “Roman courtier” (Dr. Viccius) resident in Wittenberg. It was, however, the promise he received of material help which spurred Luther on to give a social aspect to his theological movement and thus to ensure the support of the disaffected Knights and Humanists. Concerning Silvester von Schauenberg, he wrote to a confidant, Wenceslaus Link: “This noble man from Franconia has sent me a letter ... with the promise of one hundred Franconian Knights for my protection, should I need them.... Rome has written to the Prince against me, and the same has been done by an important German Court. Our German book addressed to the whole Nobility of Germany on the amelioration of the Church is now to appear; that will be a powerful challenge to Rome, for her godless arts and usurpations are therein unmasked. Farewell and pray for me.”[68] By the end of August another new book by Luther, which, like the former, is accounted by Luther’s Protestant biographers as one of the “great Reformation-works,” was in the press; such was the precipitancy with which his turbulent spirit drove him to deal with the vital questions of the day. The title of the new Latin publication which was at once translated into German was “Prelude to the Babylonish Captivity of the Church.”[69] He there attacks the Seven Sacraments of the Church, of which he retains only three, namely, Baptism, Penance, and the Supper, and declares that even these must first be set free from the bondage in which they are held in the Papacy, namely, from the general state of servitude in the Church; this condition had, so he opined, produced in the Church many other perverse doctrines and practices which ought to be set aside, among these being the whole matrimonial law as observed in the Papacy, and, likewise, the celibacy of the clergy. The termination of this work shows that it was intended to incite the minds of its readers against Rome, in order to forestall the impending Ban. This end was yet better served by the third “reforming” work “On the Freedom of a Christian Man,” a popular tract in Latin and German with its dangerously seductive explanation of his teaching on faith, justification and works.[70]
