John of Husinec, or John Hus as he is usually called, was, according to ancient tradition, born on 6th July 1369; neither day nor year of his birth are, however, absolutely certain.[29] Many tales told of the early days of Hus are taken from the records of the Bohemian brethren, written many years after his death. From the year 1400 onward authentic accounts of the events of the life of the Bohemian reformer exist, and from the year 1409 to the time of his death we have a continuous and detailed record of his life.

At a very early age Hus proceeded to Prague to pursue at the university there the studies required for the purpose of entering the Church. With his usual candour and simplicity Hus himself tells us that he originally decided to adopt the ecclesiastical career rather for the purpose of gaining a living than through any special vocation. It is, however, certain that during his years of study he already led a pious and studious life. He has indeed confessed[30] that before he was ordained "he had been fond of playing chess, thus wasting time and causing irritation" (to his partners). Such a confession, written while he was preparing for his fatal journey to Constance, proves indeed how little he had to confess, and is a touching instance both of his extremely sensitive conscience and of the profound humility so characteristic of Hus.

In September 1393 Hus took the degree of bachelor of arts, in the following year that of bachelor in divinity, and in 1396 that of master of arts. His reputation for great learning seems to have spread very rapidly at the university, for in 1401 we already find him dean of the Faculty of Arts, and in the following year he became, for the first time and at an unusually early age, rector of the university of Prague. He seems soon to have attracted attention by his great learning, and by the acumen which he displayed in the learned disputations that formed so large a part of the routine of mediæval universities. His learning was at that period noticed rather than any special religious fervour. His lectures, as Dr. Lechler has conjectured, were probably founded on Wycliffe's philosophical works, which became known to the Bohemians earlier than the theological works of the English divine.

A change appears to have come over the mind of Hus about the beginning of the fifteenth century. He has himself told us that after his ordination as a priest (probably in 1400) he led a yet simpler and more ascetic life. The principal cause of the enthusiasm, both religious and national, that henceforth distinguishes Hus was, however, undoubtedly his appointment in 1402 as rector and preacher at the Bethlehem Chapel in Prague. The foundation of the Bethlehem Chapel, which took place in 1391, and was the work of Križ, a tradesman of Prague, and John of Milheim, one of the courtiers of King Wenceslas, is an important manifestation of the desire to reform the Roman Church and to enlarge the sphere of the native language, which was then gaining ground in Bohemia. In their deed of endowment the founders stated that their object was the encouragement of the preaching of biblical doctrines in the Bohemian language. No special provision for the reading of masses was made, and no doubt many Bohemians, after hearing mass in other churches where German sermons were still preached, then proceeded to the Bethlehem Chapel. The stress laid on the preaching of the Gospel, one of the points to which the partisans of Church reform attached great importance, proves that the founders, or at least Milheim, sympathised with this movement. The increased use of the Bohemian language for preaching and its general development greatly irritated the Germans in Bohemia, who believed their preponderant position in the town and University of Prague to be menaced. The Germans in Bohemia were therefore thoroughgoing partisans of the Church of Rome, rather from antagonism to their fellow-citizens of Slav nationality than from any sympathy for the abuses then prevailing in the Roman Church. This division by nationalities, according to which the Bohemians favoured Church reform, while the Germans defended the authority of Rome, continued during the whole period of the Hussite wars, and indeed far later. It was only with the appearance of Luther that this distinction entirely ceased.

The sermons of Hus at the Bethlehem Chapel immediately attracted general attention. His great eloquence is evident in the few sermons of Hus that have been preserved, as well as in the fragments of them which he undoubtedly afterwards introduced into his Postilla. He seems to have preached on a wide range of subjects, and by no means to have eschewed the topics of the day. In one of Hus's earliest sermons[31] he refers to the invasion of Bohemia by the troops of the Margrave of Meissen, the ally of Rupert, Elector-Palatine, whom the enemies of King Wenceslas had elected King of the Romans. It is easy to imagine the strong impression which Hus's fiery words produced on his Bohemian audience, which, though thoroughly aware of the many faults of King Wenceslas, yet supported him against his German rival. "The Bohemians," Hus said, "are more wretched than dogs or snakes, for a dog defends the couch on which he lies, and if another dog tries to drive him away, he fights with him; and a snake does the same. But us the Germans oppress, seizing all the offices of state while we are silent. Bohemians in the kingdom of Bohemia, according to all laws, indeed also according to the law of God, and according to the natural order of things, should be foremost in all the offices of the Bohemian kingdom; thus the French are so in the French kingdom, and the Germans in the German lands. Therefore should a Bohemian rule his own subordinates, and a German German (subordinates). But of what use would it be that a Bohemian, not knowing German, should become a priest or a bishop in Germany? He certainly would be as useful as a dumb dog who cannot bark is to a herd! And equally useless to us Bohemians is a German; and knowing that this is against God's law and the regulations, I declare it to be illegal!" Though the date of this sermon is certain, and its immediate motive consisted no doubt in the cruelties that German troops were then committing in Bohemia, yet it is evident that Hus already had in view the preponderating influence which the Germans exercised in the university and city of Prague.

It is noteworthy that Hus was during the early days of his priesthood on good terms with his ecclesiastical superiors at Prague. This continued to be the case even after discussions on the teaching of Wycliffe had in 1403 begun to disturb the peace of the university. At a meeting of the magisters which took place in May of that year, and over which Walter Harasser, then rector of the university, presided, the twenty-four articles from Wycliffe's writings which the London Synod had already declared either heretical or erroneous, were laid before the assembly by John Kbel and Wenceslas of Bechin, canons of the chapter of Prague, the archiepiscopal seat then being vacant. Besides these twenty-four articles, the representatives of the archbishopric brought twenty-one other articles to the notice of the magisters, which a German member of the university, one John Hübner, had selected from Wycliffe's writings, and submitted to the ecclesiastical authorities. The articles of Hübner, as Hus truthfully declared, contained various statements that cannot be found in Wycliffe's works. "After these articles had been read out, and Magister Walter Harasser, the rector, had carefully noted down the votes of each and all the magisters present as representatives of the university of Prague, it was decided by a majority of the votes of the members of the university that no one should dogmatise, preach, or assert, publicly or privately, the articles which had been presented to the lord rector by John, official of the archbishopric, and Wenceslas, the archdeacon, under penalty of violating his oath."[32] A renewed discussion on the teaching of Wycliffe took place somewhat later; this time, however, the matter was only brought before the Bohemian "nation", one of the four sections into which the university of Prague was then divided. The condemnation of the articles taken from Wycliffe's works was renewed with a restriction—suggested by Hus—which stated that no master or scholar of the Bohemian "nation" should defend these articles in their false, erroneous, or heretical sense.

Shortly after the first deliberation on Wycliffe's articles, Zbyněk Zajic of Hasenburg was elected Archbishop of Prague. A member of one of the most ancient Bohemian families, Zbyněk had—though long ordained a priest and for some time provost of the town of Mélnik—devoted himself mainly to political and military matters, as was then so frequently the case with ecclesiastics of high descent. Though his ignorance has been exaggerated, he certainly possessed no profound knowledge of theology. He brought, however, to his new office a strong feeling of indignation against the immorality and dishonesty of the clergy of his archdiocese, and had, at least at first, a firm determination to remedy these evils by establishing a system of severer discipline among his subordinates. It is a striking proof of the great respect in which Hus was then held, both because of his pure and honourable life and because of his great learning, that the Archbishop's attention was immediately directed to him. "At the commencement of his rule," the Archbishop, as Hus afterwards recalled to his memory, "ordered him, whenever he noticed any irregularity contrary to the rules of the Church, to bring such irregularity to his (the Archbishop's) knowledge, either in person, or, in case of absence, by means of a letter."[33] The Archbishop gave a further proof of his confidence in Hus when he appointed him one of the preachers before the synod of the diocese. These assemblies were held by Archbishop Zbyněk more frequently than by his predecessors; he no doubt thought that they would contribute to the reformation of his clergy, which he had so much at heart. Of the sermons preached before the synod by Hus, only few have been preserved, but they are sufficient to prove how mercilessly he censured the immorality, avarice, and haughtiness of the Bohemian clergy. These accusations, which were unfortunately but too well founded, caused many to become enemies of Hus, those in particular to whom Hus's words were specially applicable.

The amicable relations that at first existed between Hus and his Archbishop did not continue long. In 1408 the clergy of the city of Prague and of the archdiocese forwarded to the Archbishop a written statement complaining of Hus's preaching in the Bethlehem chapel. In this document—printed by Palacký—it was stated that Hus had, "in opposition to the decisions of the Holy Church and to the opinions of the holy fathers, and to the injury, shame, detriment, and scandal of the whole clergy and the people generally," declared heretics all those priests who received remuneration for the administration of the sacraments or for other ecclesiastical functions, whether such payment took place before or after the ceremony. Hus was further accused of having spoken strongly against the ecclesiastics who held numerous benefices. Hus indeed wrote an eloquent defence of his preaching, and certainly succeeded in proving that Archbishop Ernest of Prague had, when issuing an enactment against the avarice of the clergy in 1364, used language almost identical with his own. Hus was none the less deprived of his office of preacher before the synod.

It is important to note that this denunciation of Hus in no way accused him of having preached anything contrary to the dogmas of the Roman Catholic Church; up to the year 1409, indeed, no such charge was ever brought forward against him. For the present, the priests of the diocese only stated that Hus had shown extreme and imprudent zeal in his endeavours to reform the clergy; such endeavours necessarily met with the approbation of the worthier priests; the others could not, at any rate, openly oppose them.

Relations with the Archbishop were yet further embittered by a letter which Hus addressed to him in July 1408 in defence of Nicholas (or Abraham) Velenovic, a priest who had been accused of preaching Wycliffe's doctrine with regard to communion. As a Protestant divine, Dr. Lechler has truly remarked, this letter reaches the extreme limit of what is permissible to a priest when writing to his ecclesiastical superiors. At the end of his letter Hus addresses the Archbishop in these words: "Therefore, most reverend father, open your eyes inwardly and within, love the good, observe those who are evil, do not let the ostentatious and avaricious flatter you; rather let the humble and the friends of poverty find favour with you; oblige the indolent to work; do not hinder those who work steadfastly at the harvest of the Lord."[34] It was inevitable that the form, if not the contents, of this letter should cause offence. It is indeed a characteristic of Hus, that while always speaking of himself with extreme humility and almost exaggerating his petty failings, he yet uses authoritative, not to say provocatory, language when he considers himself as defining "God's law."
