The archbishop of Prague, finding the reformists daily increasing, issued a decree to suppress the farther spreading of Wickliffe's writings: but this had an effect quite different to what he expected, for it stimulated the friends of those doctrines to greater zeal, and almost the whole university united to propagate them. Being strongly attached to the doctrines of Wickliffe, Huss opposed the decree of the archbishop, who, however, at length, obtained a bull from the pope, giving him commission to prevent the publishing of Wickliffe's doctrines in his province. By virtue of this bull, the archbishop condemned the writings of Wickliffe: he also proceeded against four doctors, who had not delivered up the copies of that divine, and prohibited them, notwithstanding their privileges, to preach to any congregation. Dr. Huss, with some other members of the university, protested against these proceedings, and entered an appeal from the sentence of the archbishop. The affair being made known to the pope, he granted a commission to cardinal Colonna, to cite John Huss to appear personally at the court of Rome, to answer the accusations laid against him, of preaching both errors and heresies. Dr. Huss desired to be excused from a personal appearance, and was so greatly favoured in Bohemia, that king Winceslaus, the queen, the nobility, and the university, desired the pope to dispense with such an appearance; as also that he would not suffer the kingdom of Bohemia to lie under the accusation of heresy, but permit them to preach the gospel with freedom in their places of worship. Three proctors appeared for Dr. Huss before cardinal Colonna. They endeavoured to excuse his absence, and said, they were ready to answer in his behalf. But, the cardinal declared Huss contumacious, and excommunicated him accordingly. The proctors appealed to the pope, and appointed four cardinals to examine the process: these commissioners confirmed the former sentence, and extended the excommunication not only to Huss but to all his friends and followers. From this unjust sentence Huss appealed to a future council, but without success; and, notwithstanding so severe a decree, and an expulsion in consequence from his church in Prague, he retired to Hussenitz, his native place, where he continued to promulgate his new doctrine, both from the pulpit and with the pen. The letters which he wrote at this time were very numerous; and he compiled a treatise in which he maintained, that reading the book of protestants could not be absolutely forbidden. He wrote in defence of Wickliffe's book on the Trinity; and boldly declared against the vices of the pope, the cardinals, and clergy, of those corrupt times. He wrote also many other books, all of which were penned with a strength of argument that greatly facilitated the spreading of his doctrines.
