To Bareille, who was Professor of Patrology at the Catholic University of Toulouse, Eternal Memory!
This name, taken from the Latin word calix, used to describe, among supporters of John Huss, who in the fifteenth century, reducing the minimum of their claims to four articles, vindicated especially the use of the chalice or communion under both species for the laity. Communion sub utraque was not unknown in Christian practice, see COMMUNION UNDER BOTH SPECIES [Vol. 3, col. ####; PDF ###-###], but the Church had long prohibited it because of its disadvantages. Huss himself, at least in its early days, had not thought to resume this use without the express consent of the Church. But some of his supporters, under the inspiration of Jacobel, vindicated the right to practice it. And the Council of Constance, faithful to the prescriptions of the past sages and suspecting moreover, not without reason, that this innovation masked some dogmatic error on the real presence, condemned in its thirteenth general session, June 15, 1415.

X, p. 477-478. But neither the Archbishop of Prague or the king of Bohemia, Wenceslas could enforce the decree of the council. Jacobel composed a violent diatribe against the Fathers of Constance he called "the doctors of the use." And Huss, changing of attitude that prisoner, hastened to write to his disciple Haulick, who had replaced the flesh in Bethlehem, not oppose the use of the chalice, not to fight Jacobel, and his friend Christian to adjure Bohemian nobility of having to defend a use which the council had to ban contrary to the teaching of the Gospel and the primitive tradition. The execution of Huss, which occurred on the following July 6, aroused the indignation of supporters of the chalice and excited a bloody revolt in Bohemia. Despite the intervention of the Bishop of Leitomysl, who was powerless to avert the storm, the nobility sent a protest to the council, notifying its refusal to obey. The use of the chalice was maintained and widespread; it became a rallying sign, the symbol of Calixtines.
Since 1418 the council tasked King Wenceslas with protecting the Catholic faith, purging the University of Prague, and bringing before the Roman court the main instigators of heresy. It decided that the laity who had received communion under both species should abjure their error and that the writings of Jacobel were to be delivered and destroyed. Pope Martin V, in his bull Inter cunctas in February 1418, ratifies these decisions and requires that heretics are asked about whether they admit the real presence in each species, and if they agree to do more communion under one. Hefele, op. cit., vol. XI, p. 69-79. Neither John Dominic nor Beautfort, Bishop of Winchester, nor Julian Cesarini, successively sent as cardinal legates to pacify Bohemia were successful; all efforts were useless. The Hussites persisted; moreover, taking advantage of the royal weakness, they organized militarily, putting no bounds to their audacity and prelude to a long and bloody tragedy. In 1419, they refused to recognize the Emperor Sigismund as king. The blind John Žižka took over the party of this revolutionary and heretical movement; he built a fortress, 25 miles from Prague on Mount Hardistin, which he named Tabor. At his death in 1424, divisions burst forth and four parties were formed: that of the Taborites, turbulent and unscrupulous minority, with Prokop the Great; that of Orphaniens, Orphanites or Orophelins, many more with Prokop the Little; that of Orebites without a hint of doctrine but equal agitation; and finally that of the moderates, the people of Prague or Calixtines themselves with the Bohemian [John] Rokytsana, pastor of Prague, and Wycliffite Englishman Peter Payne.
Julian Cesarini, charged in 1431 by Martin V to open and chair the Council of Basel and confirmed in these functions by Eugene IV, was quick to enter into relations with moderate Czech Calixtines, hoping to bring them back. ...
