Eastern Christianity liturgy according to Saint John Paul II

 

In Venice, before the representatives of the ecclesiastical world, who held a rather narrow idea of the Church and were opposed to this vision, Saint Cyril defended it with courage. He showed that many peoples had already in the past introduced and now possessed a liturgy written and celebrated in their own language, such as " the Armenians, the Persians, the Abasgians, the Georgians, the Sogdians, the Goths, the Avars, the Tirsians, the Khazars, the Arabs, the Copts, the Syrians and many others".

Reminding them that God causes the sun to rise and the rain to fall on all people without exception, he said: "Do not all breathe the air in the same way? And you are not ashamed to decree only three languages (Hebrew, Greek and Latin), deciding that all other peoples and races should remain blind and deaf! Tell me: do you hold this because you consider God is so weak that he cannot grant it, or so envious that he does not wish it?". To the historical and logical arguments which they brought against him Cyril replied by referring to the inspired basis of Sacred Scripture: "Let every tongue confess that Jesus Christ is Lord, to the glory of God the Father"; "All the earth worships you; they sing praises to you, sing praises to your name"; "Praise the Lord, all nations! Extol him, all peoples!".

...

Furthermore, the translation of the sacred books, carried out by Cyril and Methodius together with their pupils, conferred a capacity and cultural dignity upon the Old Slavonic liturgical language, which became for many hundreds of years not only the ecclesiastical but also the official and literary language, and even the common language of the more educated classes of the greater part of the Slav nations, and in particular of all the Slavs of the Eastern Rite. It was also used in the Church of the Holy Cross in Cracow, where the Slav Benedictines had established themselves. Here were published the first liturgical books printed in this language. Up to the present day this is the language used in the Byzantine liturgy of the Slavonic Eastern Churches of the Rite of Constantinople, both Catholic and Orthodox, in Eastern and South Eastern Europe, as well as in various countries of Western Europe. It is also used in the Roman liturgy of the Catholics of Croatia.

22. In the historical development of the Slavs of Eastern Rite, this language played a role equal to that of the Latin language in the West. It also lasted longer than Latin in part until the nineteenth century-and exercised a much more direct influence on the formation of the local literary languages, thanks to its close kinship with them. These merits vis-à-vis the culture of all the Slav peoples and nations make the work of evangelization carried out by Saints Cyril and Methodius in a certain sense constantly present in the history and in the life of these peoples and nations.
