Pope John VIII. in 879, wrote as follows to the Moravians: “Methodius, your archbishop, ordained by our predecessor Adrian, and sent to you,” &c. Whereas he calls Cyril only the philosopher, of whom he writes to Count Sfendopulk, “The Sclavonian letters or alphabet invented by Constantine the philosopher, that the praises of God may be sung, we justly commend.” (Ep. 194, ad Tuvantarum.) (This is a direct quote from Fr. Alban Butler, “Lives of the Saints”, December 22. SS. Cyril and Methodius)
