But you're unlikely to hear much of that this year. Not of Moscow has its way. St. Cyril composed an alphabet for the Slavs which is the parent of the current Russian, Ukrainian, Serbian and Bulgarian orthography. Even though the Polish, Czech, Slovenian, most of Slovak and Croatian people now belong to the Roman Rite, originally they did not and were subducted under the authority of German bishops as the Carolingian military began to subdue these areas by the power of the sword. Most Romanians, some Albanians and many Hungarians are also members of the Byzantine Rite, as well as many of the people of Southern Italy and Sicily.
People still speak it in their homes.
The use of English is widespread in the United States in all usages of the Byzantine Rite.
