King Ladislas of Naples still recognised Gregory XII. as Pope, and had therefore incurred the bitter enmity of Pope John XXIII. The latter decided on undertaking a crusade against the King of Naples, and caused a decree to be read in all churches promising all those who should contribute to the expenses of the intended expedition the same remission of sins that had been formerly granted to those who fought against the infidels in Palestine. In May 1412, Wenceslas Tiem, Dean of Passau, arrived at Prague, and immediately began to collect money for the intended crusade. This caused great irritation among the population of Prague, then almost entirely favourable to Hus and his doctrines. Hus and his followers had already previously frequently denounced the system of indulgences, and they now renewed their attacks with increased vigour. A very stormy meeting of the members of the university took place on June 7, though the theological faculty had forbidden all bachelors of theology to attack the papal decree. Hus in an eloquent speech sharply attacked the practice of granting indulgences in the manner then usual at Rome. Of the contents of this speech we can form a certain judgment from a pamphlet on the same subject which Hus published about this time and which has been preserved. He emphatically maintained that priests had the right of remitting sins to those only who showed signs of repentance and penitence, but not merely on receipt of a sum of money. Hus's teaching was here very similar to that of Wycliffe, and his opposition to the crusade against the King of Naples recalls that of Wycliffe against the Flemish crusade of Henry Spencer, Bishop of Norwich. Meanwhile the Theological Faculty of Prague again condemned as heretical the forty-five articles drawn from Wycliffe's works, now adding six more which were attributed to Hus; it was stated that they had been extracted from his speech against indulgences (on June 7) and from his pamphlet on the same subject. About the same time a considerable portion of the clergy of Prague forwarded to Pope John a written complaint against Hus. The author was a German, one Michael of Deutschbrod, also known as Michael de Causis, one of the most steadfast opponents of Hus and of Church reform. In this document Hus was accused of railing (_oblatrare_) against the clergy and against the papal indulgences, and also of having "by means of his writings spread his pestilential opinions through various districts of the kingdom of Bohemia, Poland, Hungary, and the marquisate of Moravia."[41] The consequence of these denunciations was a papal decree pronouncing the "aggravation" of the excommunication of Hus which had already been proclaimed by Cardinal Colonna in the previous year. Several of the former adherents of Hus, such as Stanislas of Znaym and Stephen Paleč, now abandoned his cause, and the latter afterwards became one of his most dangerous opponents at the Council of Constance.
