In Münster lived a draper, Bernhard Knipperdolling by name, who assembled the malcontents in his house, or in a tavern, and poured forth in their ears his sarcasms against the Pope, the bishops, the clergy and the Church. He was well known for his dangerous influence, and the bishop, Frederic von Wied, arrested him as he passed near his residence at Vecht. The people of Münster, exasperated at the news of the captivity of their favourite, obliged the magistrates and the chapter to ask the bishop to release him. Frederick von Wied yielded with reluctance, using these prophetic words, "I consent, but I fear that this man will turn everything in Münster and the whole diocese upside down." Knipperdolling left prison, after having taken an oath to keep the peace; but on his return to Münster he registered a vow that he would terribly revenge his incarceration and would make the diocese pay as many ducats as his captivity had cost him hellers.[56] [56] Kerssenbroeck, p. 143. There was another man in Münster destined to exercise a fatal influence on the unfortunate city. This was a priest named Bernard Rottmann.[57] As a child he had been chorister at St. Maurice's Church at Münster, where his exquisite voice had attracted notice. He was educated in the choir school, then went to Mainz, where in 1524 he took his Master's degree, and returning to Münster, was ordained priest in 1529. He was then given the lectureship of the church in which, as a boy, he had sung so sweetly. He shortly exhibited a leaning towards Lutheranism, and the canons of St. Maurice, who had placed great hopes on the young preacher, thinking that he acted from inexperience and without bad intent, gave him a paternal reprimand, and provided him with funds to go to the University of Cologne, and study there dogmatic and controversial theology; at the same time undertaking to retain Rottmann in the receipt of his salary as lecturer, and to this they added a handsome pension to assist him in his studies.
