Then followed a lengthy controversy on all the heretical doctrines of the Anabaptist sect, in which the king exhibited no little skill. The preachers having brought the charge of novelty against Anabaptism, John of Leyden very promptly showed that those living in glass houses should not throw stones, by pointing out that Lutheranism was not much older than Anabaptism, that he had proved his mission by miracles, whereas Luther had nothing to show to demonstrate his call to establish a new creed. The discussion on Justification by Faith only was most affectionate, for both parties were quite agreed on this doctrine--surely a very satisfactory one and very full of comfort to John of Leyden. But on the doctrine of the Eucharist they could not agree, the king holding to Zwingli.[277] [277] "Denn wiewol ichs fur dieser zeit mit dem Zwingel gehalten," &c., f. 384. "That in this Sacrament the faithful, who are baptised, receive the Body and Blood of Christ believe I," said the king; "for though I hold for this time with Zwingli, nevertheless I find that the words of Christ (This is my Body, This is my Blood) must remain in their worth. But that unbelievers also receive the Body and Blood of Christ, that I cannot believe." _The Preachers_: "How that? Shall our unbelief avail more than the word, command and ordinance of God?" _The King_: "Unbelief is such a dreadful thing, that I cannot believe that the unbelievers can partake of the Body and Blood of Christ." _The Preachers_: "It is a perverse thing that you should ever try to set our faith, or want of faith, above the words and ordinance of God. But it is evident that our faith can add nothing to God's ordinance, nor can my unbelief detract anything therefrom. Faith must be there, that I may benefit by such eating and drinking; but yet in this matter must we repose more on God's command and word than on our faith or unbelief." _The King_: "If this your meaning hold, then all unbelievers must have partaken of the Communion of the Body and Blood of Christ. But such I cannot believe." _The Preachers_: "You must understand that our unbelief cannot make the ordinance of God unavailing. Say now, for what end was the sun created?" _The King_: "Scripture teaches that it was made to rule the day and to shine." _The Preachers_: "Now if we or you were blind, would the sun fail to execute its office for which it was created?" _The King_: "I know well that my blindness or yours would not make the sun fail to shine."
