Church Slavonic
old Slavic language used in the liturgy of some branches of the Orthodox Church
Church Slavonic is a Slavic language belonging to the South-Slavic linguistic sub-branch of Balto-Slavic languages, in the Indo-European family. It is used, both historically and in the modern era, as a liturgical language by various Eastern Christian denominations. During medieval and early modern periods, it was also used as a literary language among Slavs. It stemmed from the Old Church Slavonic (9th-10th centuries), and later developed by adopting various regional and dialectal influences from local Slavic vernaculars, thus branching into several varieties, also called recensions, or redactions.
In its conservative form, that was standardized in the 18th century, it is used today by Eastern Orthodox churches in Belarus, Bosnia and Herzegovina, Bulgaria, Czechia and Slovakia, Croatia, North Macedonia, Montenegro, Poland, Russia, Serbia, Slovenia, and Ukraine. The language also appears in the services of the Russian Orthodox Church Outside of Russia, the American Carpatho-Russian Orthodox Diocese, and occasionally in the services of the Orthodox Church in America.
In addition, Church Slavonic is used by some churches which consider themselves Orthodox but are not in communion with the Orthodox Church, such as the Montenegrin Orthodox Church and the Russian True Orthodox Church. The Russian Old Believers and the Co-Believers also use Church Slavonic. The language is also used in some communities belonging to the Orthodox Church of Finland.
Church Slavonic is also used by Greek Catholic Churches in Slavic countries, for example the Croatian, Slovak, and Ruthenian Greek Catholics, as well as by the Roman Catholic Church (Croatian and Czech recensions).

Why this record matters
The phrase “old Slavic language used in the liturgy of some branches of the Orthodox Church” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q33251. The Library of Congress control number is sh85025754. Authority coordinates are 50.000, 30.000. 1 of 4 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
