!XIII Leo pápa encyclikajából
The brethren Cyril and Methodius were born in an honourable position at Thessalonica. As they advanced in years they went to Constantinople to study letters in the capital of the Eastern world. Both made quick progress, but most chiefly Cyril, who gained such learning that he was called for excellency the Philosopher. Methodius became a monk, but the Empress Theodora, on the recommendation of the Patriarch Ignatius, deemed Cyril worthy of receiving the task of teaching Christianity to the Khazar who dwelt beyond the Crimea. By the grace of God he so taught them that they laid aside their many superstitions and were joined to Jesus Christ. After properly establishing the new community of Christians Cyril hastened back to Constantinople, where he entered the monastery of Polychron, whither Methodius had already withdrawn himself. Rastilaw, Prince of Moravia, having heard tell of the good deeds beyond the Crimea, sent to Constantinople to the Emperor Michael III. to obtain some Gospel labourers. Cyril and Methodius were sent to him, and gladly received in Moravia, and applied themselves with such power and industry to the work of Christianising souls that it was not long before that nation also joyfully submitted to Jesus Christ. To this end Cyril found of great use the knowledge of the Slavonic language, which he had already acquired, and much effect was produced by the translation of holy Scripture which he made into the language of the people. Cyril and Methodius were the inventors of the alphabet in which the language of the Slavs is characteristically expressed, and for this reason they have been not unjustly termed the fathers of Slavonic literature.
