The Bet Din of the once Central Spiritual Board of the Russian Qaraim Abroad is the Central Spiritual Board of Qaraites formerly Russian and abroad. It exists as a service for the average Russian "Qaraim" style Sabbatarian (Karaim Subbotnik) in the Galut, to offer support by providing documents for births, brit milah (for Qaraim Sabbatarians admitted to the seminary only), religious status, marriages, aliyah, divorces and deaths.
The "Qaraim umma" consists of "Zera Yisrael" congregations from many nations claiming a relationship to the Qaraim religious identity or heritage in one way or another. However, while neither the average "Qaraim" Sabbatarian (Karaim Subbotnik) abroad of Lithuanian origin (e.g. in Poland) nor of Crimean origin needs a high central religious body, there has long been a need for the Russian-style "Qaraim" of any ethnicity (Sabbatarians numbering around 30,000 related to Qaraism only by descent from and/or religious affiliation with the "Qaraimist" Molokan-Subbotniki a.k.a. Qaraimizers of Qaraimizm originating in the former lands of all Rus') to have one high central religious body for records concerning births, brit milah (for Qaraim Sabbatarians admitted to the seminary only), religious status, marriages, aliyah, divorces and deaths in the same way that the Qaraims originating in Lithuania and Crimea have had. Thus the Central Spiritual Board for the Russian Qaraim abroad has become the highest central religious body of the Qaraim umma for all the affiliates and descendants of the Qaraims originating in the Former Russian Empire wherever they live today.
NB The CSBRQA Bet Din is a records office only for such religious affiliates (Караимствующие) as described above whether as Qaraims (Ezrakhim) or Qaraimits (Gerim) and never seeks to represent the descendants of those Sabbatarians (Subbotniki) who became the Lithuanian Qaraims (Karaimai), nor Crimean Qaraims (Кърымкъарайлар), nor Abyssinian Qaraims (Falashas), nor Egyptian Qaraims (Ishmaelites), nor Byzantine Qaraims (Romaniotes), nor Palestinian Qaraims (Hebrews) nor anyone who primarily considers themself to be Qaraim because of some imagined ethnic reason. Spiritually, all Qaraim Sabbatarians, whether Ger or Ezrakh, are Israelites and acceptable proof of that identity is in nothing other than being shomer masoret.
