But when these points had been settled, there still remained the real subjects of dispute. These were the lawfulness of the Slavonic ritual, and the position of Methodius as Archbishop of Moravia. Svatopluk had thrown himself with eagerness into the cause of Methodius’s opponents, and joined in the denunciation of the Slavonic ritual, declaring that it degraded worship by connecting it with a barbarous dialect. The champions of the Latin ritual attempted to strengthen their cause by referring to the inscription written by Pilate on the Cross in Hebrew and Greek and Latin. This argument brought them the nickname of Pilatici, or followers of Pilate, while Methodius and his disciples appealed, in answer, to the authority of the Apostles, who, on the Day of Pentecost, had uttered in all languages the wonderful works of God. Pope John seems clearly to have understood that the opposition to Methodius arose rather from prejudice of race than from ecclesiastical principle; and he recognised this fact in the Bull which sanctioned the Slavonic ritual. For in this document he expressly required that all the clergy in the diocese of Moravia and Pannonia, whether Slav or of whatever race they might be, should be submissive to the archbishop. A very noteworthy modification was subjoined to this decision which seemed to stamp a popular and democratic character on the Slavonic movement. “If Svatopluk,” said the Pope, “and the members of his Court desire to use the Latin ritual, they may do so still.”

An even more crushing blow to the hopes of the enemies of Methodius was given in a second decision of the Pope. The German party had persuaded Svatopluk to appoint a preacher named Wiching as Bishop of Nitra in Pannonia, thereby hoping at any rate to counterbalance the authority of Methodius. Pope John, however, decided that he would only recognise this appointment on condition that Wiching acknowledged the archbishop as his superior; and he expressly recommended Svatopluk to choose his next bishop with the advice and consent of Methodius. So alarmed were Wiching and his friends at this letter from the Pope that they succeeded in suppressing it, before it could reach Svatopluk; and they forged another in which the Pope was made to say that Methodius had indeed recanted his heresy about the Double Procession; but that he was forbidden to use the Slavonic ritual, and that Bishop Wiching was appointed to carry out the papal decrees.

Methodius denied the genuineness of the document, and wrote to Rome for another letter. John confirmed his former decree, and summoned Wiching to Rome to answer for his proceedings. Wiching, however, refused to go; and he was backed in his opposition both by Svatopluk and by Arnulf, the claimant of the Empire, whose hold over Pannonia had been one of the chief causes of the opposition to the episcopal authority of Methodius.

The relations between Methodius and Svatopluk, always hostile, would now have probably culminated in the death or exile of the archbishop, but that a quarrel broke out between Svatopluk and Arnulf; and the desire of Svatopluk to overthrow Arnulf’s influence in Pannonia naturally hindered his action against Methodius. For the few remaining years of the archbishop’s life, he was able to carry on his work, both moral and religious, with much less opposition; but when, after his death, his friends attempted to get his pupil Gorazd appointed as successor in the archbishopric, Wiching succeeded in stirring up Svatopluk against him, in renewing the alliance with Arnulf, and finally in securing the expulsion from Moravia of the leading followers of Methodius. But in spite of the opposition of dukes and Germans, the Slavonic ritual held its own in Moravia, and Svatopluk’s son Mojmir became its champion against the bishops of Salzburg.

Important, however, as the defence of the Slavonic language and ritual was in the history of Bohemia and Moravia, the enemy against whom it had specially served as a watchword had ceased to become the object of uncompromising hostility. A new power had made its way into Europe, more dangerous, for the moment, to Slavonic unity and Bohemian independence than Frank, Saxon, or Bavarian; and the Bohemians and Moravians were for a time compelled to forget their fears and hatred of the Germans, in order to combine with them against a new enemy.
