Slavorum Apostoli §7

⁷ His far-seeing work, his profound and orthodox doctrine, his balance, loyalty, apostolic zeal and intrepid magnanimity gained Methodius the recognition and trust of Roman Pontiffs, of Patriarchs of Constantinople, of Byzantine Emperors and of various Princes of the young Slav peoples. Thus he became the guide and legitimate Pastor of the Church which in that age became established in the midst of those nations. He is unanimously venerated, together with his brother Constantine, as the preacher of the Gospel and teacher "from God and the holy Apostle Peter", and as the foundation of full unity between the Churches of recent foundation and the more ancient ones. For this reason, "men and women, humble and powerful, rich and poor, free men and slaves, widows and orphans, foreigners and local people, the healthy and the sick" made up the throng that amid tears and songs accompanied to his burial place the good Teacher and Pastor who had become "all things to all men, that I might by all means save some". To tell the truth, after the death of Methodius the work of the holy Brothers suffered a grave crisis, and persecution of their followers grew so severe that the latter were forced to abandon their missionary field. Nonetheless, their sowing of the Gospel seed did not cease to bear fruit, and their pastoral attitude of concern to bring the revealed truth to new peoples while respecting their cultural originality remains a living model for the Church and for the missionaries of all ages.
