And when Cyril and Methodius had preached the Word of God among the Bulgarians, they journeyed on, bearing the bones of S. Clement, and their Sclavonic translation of the Holy Gospels, into Moravia, where they laboured about four and a half years with great success. The bishops of the neighbouring German provinces, however, viewed the mission of these Easterns with jealousy, and complained to pope Nicolas I. of their performing the liturgy in the Sclavonic language. The unsuccessful war waged by Rostislaw with the Germans, and the deposition of Photius at Constantinople, who had commissioned the two apostles, gave Nicolas the opportunity of summoning the two Greek missionaries to Rome. On their journey (in 868) they were subjected to vexatious treatment at Venice, on account of their cause, but pope Adrian II., who had succeeded Nicolas, dreading to lose Moravia and Pannonia, received them with great cordiality, permitted them to celebrate the divine mysteries in Sclavonic at the grave of the Apostles, ordained their disciples, Formosus and Gonderik,[38] bishops, three others priests, and two lectors. He also sanctioned the use of the Sclavonic liturgy. The following account from the Lections of the Olmutz Breviary will not prove uninteresting. "The blessed Cyril, by the grace of God, after he had converted the Moravians, invented new alphabetical letters, and translated the Old and New Testaments, and many other things from Greek or Latin, into the Sclavonic tongue; and he appointed to be sung Mass, and the other canonical hours in the church. And to this day they are thus sung in Sclavonic parts, especially in Bulgaria, and thereby many souls are drawn to Christ the Lord. And when after some time the said Cyril went to Rome out of devotion, he was rebuked by the sovereign pontiff and the other rulers of the church, because, contrary to the canons, he had appointed the holy Mass to be sung in the Sclavonic tongue. But he, humbly endeavouring to satisfy them, but not able to convince them wholly, snatched up the Psalter, and read the words of the Psalmist, 'Let everything that hath breath praise the Lord.' _Omnis spiritus laudet Dominum._ And he said, 'If every one that hath breath is to praise the Lord, why, my fathers, do ye forbid me to perform the Mass in the Sclavonic tongue, or to translate other things from Latin and Greek into the vernacular? Finding the people simple and ignorant of the ways of the Lord, I, by the inspiration of God, found this means of drawing many to God. Therefore, pardon me, my fathers, and, following the example of S. Paul, the doctor of the Gentiles,--Forbid not to speak with tongues. (I Cor. xiv. 39.)' And they, hearing him, and wondering at his sanctity and faith, gave him authority in those parts to say Mass, and sing the Canonical Hours, in the aforesaid tongue."
