The deaths of King George and of Rokycana released them for a time from persecution. The new King showed himself more kindly towards them. This King was Ladislaus, the son of the King of Poland. He had been chosen King of Bohemia, in spite of the resistance of Matthias. He was only sixteen years old when he began to reign, and he seems to have speedily left on people around him the impression of a youth of mild and weak temperament. He released the Brothers who were still in prison, and they renewed their propaganda. But their troubles were not yet at an end. Joanna, the widow of King George, fiercely demanded their suppression; and when they asked for a free discussion on the points at issue, the Masters of the Prague University informed them that they might come to Prague to state their doctrines, and then submit to be convinced of their errors by the Masters. This was precisely what the Council of Basel had proposed to the Utraquists themselves, a proposal which they had scornfully rejected; and the inconsistent character of the claim made by the Utraquist leaders seems forcibly to have impressed, not only their Catholic enemies, but even some of their supporters. Therefore, under the pressure of public opinion, the Masters of the Prague University consented, in 1473, to a discussion with the Brothers. Strangely enough, the points which the Masters proposed for discussion did not refer to the distinctive doctrines of Peter of Chelc̆ic, but were rather concerned with the meaning of the sacrament of the Lord’s Supper, and the right means of obtaining salvation. The Brotherhood denied the doctrine of the Real Presence, and maintained that salvation was only to be found in a virtuous life; they were consequently denounced by the Masters of Prague, and very little real discussion took place. The Masters soon after issued a letter, in which they declared that the Brothers were the chief enemies of the Church; and they further complained of them for choosing workmen for the office of priests.
