Huss felt confident that he could convince the council of the truth of his views and willingly appeared at Constance. He was provided with a "safe-conduct," a document in which Emperor Sigismund ordered that no one should do him any violence and which permitted the bearer to leave Constance whenever he wished. In spite of this he was speedily arrested and imprisoned, in December, 1414. His treatment well illustrates the mediæval attitude towards heresy. When Sigismund indignantly protested against the violation of his safe-conduct, he was informed that the law did not recognize faith pledged to suspected heretics, for they were out of the king's jurisdiction. The council declared that no pledge which was prejudicial to the Catholic faith was to be observed. In judging Sigismund's failure to enforce his promise of protection to Huss it must be remembered that heresy was at that time considered a far more terrible crime than murder, and that it was the opinion of the most authoritative body in Christendom that Sigismund would do a great wrong if he prevented the trial of Huss. [Sidenote: Trial of Huss.] Huss was treated in what would seem to us a very harsh way; but from the standpoint of the council he was given every advantage. By special favor he was granted a public hearing. The council was anxious that Huss should retract; but no form of retraction could be arranged to which he would agree. The council, in accordance with the usages of the time, demanded that he should recognize the error of all the propositions which they had selected from his writings, that he should retract them and never again preach them, and that he should agree to preach the contrary. The council did not consider it its business to decide whether Huss was right or wrong, but simply whether his doctrines, which they gathered from his books, were in accordance with the traditional views of the Church. [Sidenote: Conviction and execution of Huss, July, 1415.] Finally, the council condemned Huss as a convicted and impenitent heretic. On July 6, 1415, he was taken out before the gates of the city and given one more chance to retract. As he refused, he was degraded from the priesthood and handed over to the civil government to be executed for heresy, which, as we have seen, the state regarded as a crime and undertook to punish.[208] The civil authorities made no further investigation but accepted the verdict of the council and burned Huss upon the spot. His ashes were thrown into the Rhine lest they should become an object of veneration among his followers. [Sidenote: The Hussite wars, 1419-1431.]
