Rottmann had for some while been wavering in his adhesion to Lutheranism.[108] He doubted first, and then disbelieved in the Real Presence, which Luther insisted upon. He thought that the reformation of the Wittenberg doctor was not sufficiently thoroughgoing in the matter of ceremonial; then he doubted the scriptural authority for the baptism of infants. Two preachers, Heinrich Rott and Herman Strapedius, fell in with his views. The former had been a monk at Haarlem, but had become a Lutheran preacher. He regarded the baptism of infants as one of those things which are indifferent to salvation. Strapedius was more decided; he preached against infant baptism as an abomination in the sight of God. He was named by the people preacher at S. Lambert's, the head church of the city, in spite of the opposition of the authorities.[109] [108] Kerssenbroeck, p. 429 _et seq._; Sleidan, French tr. p. 409; Bullinger, "Adv. Anabapt.," 116, ii. c. 8. [109] Kerssenbroeck, pp. 431, 432; Dorp., f. 322-3. The Lutheran senate of Münster, which a few months previously had been elected enthusiastically by the people, now felt that before these fiery preachers, drifting into Anabaptism, their power was in as precarious a position as was that of those whom they had supplanted. Alarmed at the rapid extension of the new forms of disbelief, they twice forbade Rottmann to preach against the baptism of infants and the Real Presence, and ordered him to conform in his teaching to authorised Lutheran doctrine. He treated their orders with contempt. Then they summoned him before them: he appeared, but on leaving the Rath-haus, preached in the square to the people with redoubled violence. The senate, at their wits' end, ordered a public discussion between Rottmann and the orthodox Lutherans, represented by Hermann Busch. The discussion took place before the city Rath, and the senate decided that Busch had gained the day, and they therefore forbade all innovation in the administration of baptism and the Lord's Supper.
