The gentle Melancthon wrote a tract or letter to urge the princes on; it was entitled, "Das weltliche Oberkeiten den Widerteuffern mit leiblicher straffe zu wehren schüldig sey. Etlicher bedenken zu Wittemberg gestellet durch Philip Melancthon, 1536. Ob Christliche Fürsten schüldig sind der Widerteuffer unchristlicher Sect mit leiblicher straffe und mit dem schwert zu wehren." He enumerates the doctrines of the unfortunate sectarians at Münster and elsewhere, and then he says that it is the duty of all princes and nobles to root out with the sword all heresy from their dominions; but then, with this proviso, they must first be instructed out of God's Word by the pure reformed Church what doctrines are heretical, that they may only exterminate those who differ from the Lutheran communion.
He then quotes to the Protestant princes the example of the Jewish kings: "The kings in the Old Testament, not only the Jewish kings, but also the converted heathen kings, judged and killed the false prophets and unbelievers. Such examples show the office of princes. As Paul says, the law is good that blasphemers are to be punished. The government is not to rule men for their bodily welfare, so much as for God's honour, for they are God's ministers; let them remember that and value their office."
But it is argued on the other side that it is written, "Let both grow together till the harvest. Now this is not spoken to the temporal power," says Melancthon, "but to the preachers, that they should not use physical power under the excuse of their office. From all this it is plain that the worldly government is bound to drive away blasphemy, false doctrine, heresies, and to punish in their persons those who hold to these things.... Let the judge know that this sect of Anabaptists is from the devil, and as a prudent preacher instructs different stations how they are to conduct themselves, as he teaches a wife that to breed children is to please God well, so he teaches the temporal authorities how they are to serve God's honour, and openly drive away heresy."[281]
So also did Justus Menius write to urge on an exterminatory persecution of the sectaries; he also argues that "Let both grow together till the harvest," is not to be quoted by the princes as an excuse for sparing lives and properties.[282]
On the 12th January, 1536, John of Leyden, Knipperdolling, and Krechting were brought back to Münster to undergo sentence of death.[283]
A platform was erected in the square before the townhall on the 21st, and on this platform was planted a large stake with iron collars attached to it.
When John Bockelson was told, on the 21st, that he was to die on the morrow, he asked for the chaplain of the bishop, John von Siburg, who spent the night with him. With the fear of a terrible death before him, the confidence of the wretched man gave way, and he made his confession with every sign of true contrition.
Knipperdolling and Krechting, who were also offered the assistance of a priest, rejected the offer with contempt. They declared that the presence of God sufficed them, that they were conscious of having committed no sin, and that all their actions had been done the sole glory of to God, that moreover they were freely justified by faith in Christ.
On Monday the 22nd, at eight o'clock in the morning, the ex-king of Münster and his companions were led to execution. The gates of the city had been closed, and a large detachment of troops surrounded the scaffold. Outside this iron ring was a dense crowd of people, and the windows were filled with heads. Francis of Waldeck occupied a window immediately opposite the scaffold, and remained there throughout the hideous tragedy.[284] As an historian has well observed, "Francis of Waldeck, in default of other virtues, might at least have not forgotten what was due to his high rank and his Episcopal character; he regarded neither—but showed himself as ferocious as had been John Bockelson, by becoming a spectator of the long and horrible torture of the three criminals."[285] John and his accomplices having reached the townhall, received their sentence from Wesseling, the city judge. It was that they should be burned with red-hot pincers, and finally stabbed with daggers heated in the fire.[286]
