At an early date the government took its stand against the heresy. Luther's books were examined by a committee of the University of Cambridge, [Sidenote: 1520] condemned and burnt by them, and soon afterwards by the government. At St. Paul's in London, [Sidenote: May 12, 1521] in the presence of many high dignitaries and a crowd of thirty thousand spectators Luther's books were burnt and his doctrine "reprobated" in addresses by John Fisher, Bishop of Rochester, and Cardinal Wolsey. A little later it was forbidden to read, import or keep such works, and measures were taken to enforce this law. Commissions searched for the said pamphlets; stationers and merchants were put under bond not to trade in them; and the German merchants of the Steelyard were examined. When it was discovered [Sidenote: 1526] that these foreigners had stopped "the mass of the body of Christ," commonly celebrated by them in All Hallows' Church the Great, at London, they were haled before Wolsey's legatine court, forced to acknowledge its jurisdiction, and dealt with. With one accord the leading Englishmen declared against Luther. Cuthbert Tunstall, a mathematician and diplomatist, and later Bishop of London, wrote Wolsey from Worms of the devotion of the Germans to their leader, and sent to him _The Babylonian Captivity_ with the comment, "there is much strange opinion in it near to the opinions of Boheme; I pray God keep that book out of England." [Sidenote: January 21, 1521] Wolsey himself, biassed perhaps by his ambition for the tiara, labored to suppress the heresy. Most important of all, Sir Thomas More was promptly and decisively alienated. {283} It was More, according to Henry VIII, who "by subtle, sinister slights unnaturally procured and provoked him" to write against the heretic. His _Defence of the Seven Sacraments_, in reply to the _Babylonian Captivity_, though an extremely poor work, was greeted, on its appearance, as a masterpiece. [Sidenote: July, 1521] The handsome copy bound in gold, sent to Leo X, was read to the pope and declared by him the best antidote to heresy yet produced. In recognition of so valuable an arm, or of so valiant a champion, the pope granted an indulgence of ten years and ten periods of forty days to the readers of the book, and to its author the long coveted title Defender of the Faith. Luther answered the king with ridicule and the controversy was continued by Henry's henchmen More, Fisher, and others. Stung to the quick, Henry, who had already urged the emperor to crush the heretic, now wrote with the same purpose to the elector and dukes of Saxony and to other German princes.
