Kadylo,
This is the kind of query that drives me right off the edge (was pretty close to begin with

), as I can't get it out of my mind.
So, for your edification and education, several more acronyms and abbreviations that get bandied about here. Some (
e.g., CCEO, CIC, RISU) occur rather regularly, others (
e.g., HOCNA and TOC) only occasionally, and a few (
e.g., SCOOCH) are practically obscure (I know, folks - what a surprise coming from me

).
ACA = Armenian Church of America (Orthodox)
BC = Byzantine Catholic
CCEO = Code of Canons of the Oriental Churches(
Codex Canonum Ecclesiarum Orientalium)
CIC = Code of Canon Law (
Codex Iuris Canonici) of the Latin Church
CNEWA = Catholic Near East Welfare Association
EC = Eastern Catholic
ECUSA = Episcopal Church of the USA
FRY = former (Federal) Republic of Yugoslavia
HOCNA = Holy Orthodox Church in North America
HTM = Holy Transfiguration Monastery
IOCC = International Orthodox Christian Charities
LCMS = Lutheran Church Missouri Synod
LOL = Laughing out loud
OC = Old Catholics
OCMC = Orthodox Christian Mission Center
OCS = Old Church Slavonic
PNCC = Polish National Catholic Church
RISU = Religious Information Service of Ukraine
ROAC = Russian Orthodox Autocephalus Church
ROCA = Russian Orthodox Church Abroad
ROCiE/ROCE = Russian Orthodox Church in Exile
ROCOR(L) - Russian Orthodox Church Outside Russia (Metropolitan Lavra)
ROCOR(V) - Russian Orthodox Church Outside Russia (Metropolitan Vitaly)
ROTFL = Rolling on the Floor Laughing (not done much, we're very dignified :rolleyes: )
SCOBA = Standing Conference of Orthodox Bishops in America
SCOOCH = Standing Conference of Oriental Orthodox Churches (in America)
SVS = Saint Vladimir's Seminary
TOC = True Orthodox Church
UMC = United Methodist Church
UAOC-C = Ukrainian Autocephalus Orthodox Church - Canonical
UAOC-S = Ukrainian Autocephalus Orthodox Church - Sobornopravna
USCCB = United States Conference of Catholic Bishops
VIS = Vatican Information Service
And, before you ask, yes - the Ukrainians (and the Russians as well) deserve a listing onto themselves
I would amend my friend Gaudior's listings for:
"ACROD ... American Carpatho-Russian Orthodox" to add "Diocese" at the end of the name
"AO ... Antiochian Orthodox" to "AOCANA = Antiochian Orthodox Christian Archdiocese of North America" (the Antiochians' current usage)
There are, undoubtedly, others that escape me at the moment - but, I'll be mulling this over for days yet to come.
Many years,
Neil
