It was arranged by composer and teacher Mykola Leontovych in 1916, and tells a story of a swallow flying into a household to sing of wealth that will come with the following spring.  "Shchedryk" was originally sung on the night of January 13, New Year's Eve in the Julian Calendar (December 31 Old Style), which is "Shchedry Vechir".  Early performances of the piece were made by students at Kyiv University.

Greek Orthodox Patriarch of Jerusalem: The Greek Orthodox Patriarch of Jerusalem or Eastern Orthodox Patriarch of Jerusalem, officially Patriarch of Jerusalem, is the head bishop of the Greek Orthodox Patriarchate of Jerusalem, ranking fourth of nine Patriarchs in the Eastern Orthodox Church.  Since 2005, the Eastern Orthodox Patriarch of Jerusalem has been Theophilos III.  The Patriarch is styled "Patriarch of the Holy City of Jerusalem and all Holy Land, Syria, beyond the Jordan River, Cana of Galilee, and Holy Zion."  The Patriarch is the head of the Brotherhood of the Holy Sepulchre, and the religious leader of about 130,000 Eastern Orthodox Christians in the Holy Land, most of them Palestinians.

Mykola Leontovych: Leontovych was born and raised in the Podolia Governorate of the Russian Empire (present-day Ukraine).  He was educated as a priest in the Kamianets-Podilskyi Theological Seminary and later furthered his musical education at the Saint Petersburg Court Capella and private lessons with Boleslav Yavorsky.  With the independence of the Ukrainian state in the 1917 revolution, Leontovych moved to Kiev where he worked at the Kiev Conservatory and the Mykola Lysenko Institute of Music and Drama.  He is recognized for composing "Shchedryk" in 1904 (which premiered in 1916), known to the English-speaking world as "Carol of the Bells" or "Ring, Christmas Bells".  He is known as a martyr in the Eastern Orthodox Ukrainian Church, where he is also remembered for his liturgy, the first liturgy composed in the vernacular, specifically in the modern Ukrainian language.  He was assassinated by a Soviet agent in 1921.

Volodymyr Sabodan: Metropolitan Vladimir (Volodymyr; secular name Viktor Markianovich Sabodan, Russian: Виктор Маркианович Сабодан , Ukrainian: Віктор Маркіянович Сабодан , November 23, 1936 – July 5, 2014) was the head of the Ukrainian Orthodox Church (Moscow Patriarchate) (UOC-MP) from 1992 to 2014.  Metropolitan Volodymyr's official title was "His Beatitude Vladimir, Metropolitan of Kiev and all Ukraine".  As head of the Ukrainian Orthodox Church (Moscow Patriarchate), he was the head of the only Ukrainian Church inside Ukraine to have canonical standing (legal recognition) in Eastern Orthodoxy worldwide.

Eastern Orthodoxy in Moldova: The Eastern Orthodox Church in Moldova is organized by the Metropolis of Chișinău and All Moldova, commonly referred to as the "Moldovan Orthodox Church", a self-governing church body under the Russian Orthodox Church, and by the Metropolis of Bessarabia, also referred to as the "Bessarabian Orthodox Church", a self-governing church body under the Romanian Orthodox Church.  According to a 2011 Gallup survey on religion, among the Eastern Orthodox of Moldova, 86% belonged to the Moldovan Orthodox Church, while 13% belonged to the Bessarabian Orthodox Church.

Old Calendarists: An Old Calendarist is any Eastern Orthodox Christian or any Eastern Orthodox Church body which uses the historic Julian calendar (called "Old Style Calendar" or "Church calendar" or "Old Calendar"), and whose Church body is not in communion with the Eastern Orthodox Churches that use the New Calendar.  The "Old Calendarists" (who are also sometimes styled "Old Calendar") are to be distinguished from Eastern Orthodox Christians or Eastern Orthodox Church bodies which are "on the" Old Calendar.  The latter use the historic Julian calendar cited above, but "are" in communion with the Eastern Orthodox Churches that use the New Calendar (the Revised Julian calendar).  Thus, to be "Old Calendarist" or "Old Calendar" is not the same thing as being "on the Old Calendar".  The Russian Orthodox Church, for instance, is not Old Calendarist (or Old Calendar), but it is on the Old Calendar.  There are a great many Eastern Orthodox Christians who are (or who belong to Churches that are) "on the Old Calendar", but far fewer in number are the Eastern Orthodox Christians who are "Old Calendar" or "Old Calendarist."  It also should not be confused with the Oriental Orthodox churches, all of which are either "on" the Old Calendar or use their own calendar, but who are not in communion with either the Old Calendarists or mainstream Eastern Orthodoxy, although they are currently engaged in ecumenical dialogue with the latter.

Balamand declaration: Uniatism, method of union of the past, and the present search for full communion, also known as the Balamand declaration and the Balamand document, is a 1993 report written by the Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church during its 7th plenary session at Balamand School of Theology in Lebanon.  The report discusses ecclesiological principles and suggests practical rules for both the Catholic Church and the Eastern Orthodox Churches to implement about improving relations by reciprocally avoiding interfering in each other's Churches and not using history in a polemical manner.  According to Cardinal Edward Cassidy, the report contains three principles: that individuals have the freedom to follow their conscience, that Eastern Catholic Churches have the right to exist, that uniatism is not the current method of full communion; and two conclusions: that the Catholic Church and the Eastern Orthodox Churches are "sister churches" and that rebaptism should be avoided.  The Eastern Catholics rejected the report "because it seemed to imply they should never have existed in the first place" while the Eastern Orthodox rejected it because it did not call for the abolition of the Eastern Catholic Churches.

Saint Sava Serbian Orthodox Church: Saint Sava Serbian Orthodox Church (Serbian: Црква светог Саве; "Crkva svetog Save" ) is a Serbian Orthodox church in Jackson, California.  Built in 1894, the church was the first Serbian Orthodox church in America.  Amador County had a large Serbian-American population in the late 1800s due to the California Gold Rush, and the county's Serbs established the St. Sava Church Organization of Amador County in 1886–87; the organization was responsible for purchasing land for and building the church.  The church's original design had an Eastern Orthodox influence, complete with an onion dome; while the dome was later replaced by a bell tower, the church's stained glass windows and use of icons still give it a distinctive Eastern Orthodox character.  The church has been used for Serbian-American religious and social activities since its opening and is now part of the Serbian Orthodox Eparchy of Western America.

Greek Orthodox Church of Jerusalem: The Eastern Orthodox Patriarchate of Jerusalem (Greek: Πατριαρχεῖον Ἱεροσολύμων , "Patriarcheîon Hierosolýmōn") or Greek Orthodox Patriarchate of Jerusalem (Arabic: كنيسة الروم الأرثوذكس في القدس‎ ‎ "Kanisatt Ar-rum al-Urtudoks fi al-Quds", literally Rûm/Roman Orthodox Church of Jerusalem), and officially called simply the Patriarchate of Jerusalem, is an autocephalous Church within the wider communion of Eastern Orthodox Christianity.  Headed by the Patriarch of Jerusalem, it is regarded by Eastern Orthodox Christians as the mother church of all of Christendom.  Christians believe that it was in Jerusalem that the Church was established on the day of Pentecost with the descent of the Holy Spirit on the disciples of Jesus Christ ( ) and that the Gospel of Christ spread from Jerusalem.  The Church celebrates its liturgy in the Byzantine Rite, whose original language is Koine Greek, the original language of the New Testament, and follows its own calendar of feasts, preserving the Julian calendar (that is thirteen days behind the Western (Gregorian) calendar).  It is also often called "Σιωνίτις Εκκλησία" (Greek: Sionitis Ecclesia , i.e. the "Church of Zion").
